Important Safety Instructions  
WARNING  
This chapter contains important safety and operating instructions as required by UL and  
CSA standards for inverters used in residential applications. Read and keep this  
Installation Guide for future reference.  
1. Before using the inverter, read all instructions and cautionary markings on the  
unit, the batteries, and all appropriate sections of this manual.  
2. Use of accessories not recommended or sold by Xantrex Technology Inc. may result in  
a risk of fire, electric shock, or injury to persons.  
3. The inverter is designed to be permanently connected to your AC and DC electrical  
systems. Xantrex recommends that all wiring be done by a certified technician or  
electrician to ensure adherence to the local and national electrical codes applicable in  
your jurisdiction.  
4. To avoid a risk of fire and electric shock, make sure that existing wiring is in good  
condition and that wire is not undersized. Do not operate the inverter with damaged or  
substandard wiring.  
5. Do not operate the inverter if it has been damaged in any way. If the unit is damaged,  
see the Warranty and Product Information section at the end of this manual.

XW Inverter/Charger  
The XW Inverter/Charger is a modular “building block” sine-wave inverter/charger that  
can be used for both residential and commercial stand-alone, grid-backup, and grid-tie  
applications with battery energy storage. The XW Series is a self-contained DC to AC  
inverter, battery charger, and AC transfer switch. Up to three inverters can be installed in  
parallel to create larger 120-240-volt, 3-wire, single-phase systems allowing for increased  
capacity.  
Figure 1-2 XW Inverter/Charger  
A Battery Temperature Sensor (FGA # 808-0232-02) is also included with the XW  
Inverter/Charger. The Battery Temperature Sensor monitors the temperature of the battery  
bank and adjusts the charging accordingly. See page 2–13 for installation instructions for  
this accessory.  
XW Conduit Box  
A conduit box (FGA # 865-1025) is available to enclose the bottom of the XW  
Inverter/Charger and protect the cabling. Use of the conduit box may be required  
depending on the local electrical code. Be sure to consult with the local electrical authority

Introduction  
XW Solar Charge Controller  
The XW Solar Charge Controller (FGA # 865-1030) is a 60 amp charge controller with  
integrated PVGFP and separate Battery Temperature Sensor. The XW Solar Charge  
Controller can be used with 12-, 24-, 36-, 48-, and 60-volt DC battery systems. However,  
the XW Inverter/Charger can only work at 24 or 48 volts depending on the model. When  
the XW Solar Charge Controller is used with the XW Inverter/Charger, it is limited to 24-  
or 48-volt battery banks. The XW Solar Charge Controller will automatically detect the  
24- or 48-volt settings.  
Figure 1-6 XW Solar Charge Controller  
XW System Control Panel  
The XW System Control Panel features a graphical, backlit liquid crystal display that  
displays system configuration and diagnostic information for all devices connected to the  
network. When installed as an XW Power System accessory, the XW System Control  
Panel eliminates the need for separate control panels for each device and gives a single  
point of control to set up and monitor an entire XW Power System.

System Components and Accessories  
XW Automatic Generator Start  
The XW Automatic Generator Start can automatically activate a generator to provide an  
XW Series Inverter/Charger with power to recharge depleted batteries or assist with heavy  
loads. The XW Automatic Generator Start adds intelligence to power management and  
eliminates time spent monitoring batteries and inverter loads.  
The XW Automatic Generator Start is compatible with popular generators, and can be  
configured to start the generator in response to low battery voltage, thermostat operation,  
or load size on the inverter battery. A quiet time setting prevents the generator from  
starting at inconvenient times. LEDs display the status of the XW Automatic Generator  
Start, while all user-defined settings are programmed through the XW System Control  
Panel.  
FGA Number:  
865-1060  
Figure 1-8 Automatic Generator Start  
Generator  
The generator should be a 120/240V, 2-wire or 3-wire generator with Auto Start capability.  
Important: Do not use a 120-volt only generator. The inverter will not accept  
power from a generator of this kind.  
The generator should also supply a Generator Run signal. This signal is used by the XW  
Automatic Generator Start to detect whether the generator is running. Some generator  
manufacturers refer to this signal as the Hour Meter Signal or Switched B+.  
Generator  
Compatibility  
The XW Automatic Generator Start supports most two and three-wire generator starters.  
Some manufacturers include, but are not limited to, Onan (Quiet Diesel, gasoline, and LP),  
Power Tech, Generac, Northern Lights, Fisher Panda, Westerbeke, Kohler, Honda, and  
Yamaha. Check with the generator manufacturer to ensure the generator in question  
includes automatic starting capabilities.  
XW System Control  
Panel  
A XW System Control Panel is required to configure the XW Automatic Generator Start  
and monitor generator starting and stopping activity.  
The XW System Control Panel also provides real-time clock information for the XW  
Automatic Generator Start Quiet Time and Exercise Time features.

Inverter/Charger Installation  
Pre-Installation  
Before installing the XW Inverter/Charger, read all instructions and cautionary markings  
located in this manual.  
Important: Be sure to obtain the appropriate permits, if necessary, prior to  
starting this installation. Installations must meet all local codes and standards.  
Installations of this equipment should only be performed by skilled personnel  
such as qualified electricians and Certified Renewable Energy (RE) System  
installers.  
WARNING: Personal Injury  
The XW Inverter/Charger weighs approximately 120 pounds (54 kg). To prevent personal injury,  
always use proper lifting techniques and have someone available to assist with lifting during  
installation.  
Location  
The XW Inverter/Charger is certified for indoor (heated or unheated) installations only.  
Close to battery  
bank  
Locate the inverter as close to the batteries as possible in order to keep the battery cable  
length short. The maximum recommended battery cable length is 10 feet (3 m).  
WARNING: Explosion and Corrosion Hazard  
Do not locate the inverter directly above the batteries or in the same compartment as vented  
batteries.  
Locate any electronic equipment susceptible to radio frequency and electromagnetic  
interference as far away from the inverter as possible.  
Fire safety  
Do not locate the inverter near readily flammable materials such as cloth, paper, straw, or  
plastic sheeting. Flammable materials should be kept a minimum distance of 24 inches  
(60 cm) from the top surface and 12 inches (30 cm) from either side surface and the front  
of the XW Inverter/Charger.  
Knockout Preparation  
Remove your choice of knockouts from the chassis to facilitate conduit installation for  
wire runs. Ensure no debris from this procedure remains inside the inverter enclosure.  
Important: Do not drill, cut, or punch holes into the XW power distribution  
Panel. Use only the knockouts provided for conduit entry.

Pre-Installation  
Clearance Requirements  
Provide a minimum clearance of 6 inches (15 cm)—12 inches is preferred—around the top  
and 6 inches (15 cm) at the bottom of the inverter for ventilation. There must be at least  
three feet of clearance in front of the inverter. Ensure that the vents are not obstructed with  
foreign objects and that the minimum clearances are met.  
Figure 2-1 Clearance Requirements  
Mounting  
The XW Power System is designed to be mounted on a vertical surface. The supporting  
surface must be strong enough to support a minimum of 500 pounds (227 kg). To facilitate  
installation, a wall mounting plate (Xantrex p/n 210-0462-01-01) is provided for each XW  
Inverter/Charger and XW Power Distribution Panel. The mounting plate and hardware on  
the XW Inverter/Charger and XW Power Distribution Panel are designed to meet  
standards for structural and seismic stability. When properly installed, the system also  
meets Section 59 of UL 1741 for Static Loads.

Inverter/Charger Installation  
Step 1: Installing the Mounting Plate  
Each XW Inverter/Charger and XW Power Distribution Panel requires a separate  
mounting plate. This bracket is first attached to the wall, then the inverter/charger or  
distribution panel is attached to the wall bracket.  
The wall bracket is attached to the wall with lag bolts or other fasteners, provided by the  
installer. A minimum of four ¼-inch diameter fasteners are required. The fasteners must  
be sufficiently strong to support 500 pounds.  
The wall bracket has mounting holes spaced 16 inches (40 cm) apart and is designed to  
span two wall studs spaced 16 inches on-center. Additional mounting holes are also  
provided for flexibility in mounting options. If the wall does not have 16-inch on-center  
studs, the installer will need to provide adequate supports for the brackets. For example, a  
sheet of plywood can be attached to the wall, and the wall brackets can then be attached to  
plywood.  
Both the XW Inverter/Charger and XW Power Distribution Panel use the same wall  
bracket. The brackets are designed to interlock (as shown in Figure 2-3), so that additional  
mounting plates are easily installed without additional measuring or levelling.  
The type of fastener required to secure the mounting plate varies according to the vertical  
surface and wall structure of your installation location.

Inverter/Charger Installation  
Step 4: Wiring the Inverter  
This section provides procedures for making AC and DC connections between the XW  
Inverter/Charger and the power distribution panel using the cables that are pre-installed in  
the distribution panel. This section also assumes that the XW Conduit Box was installed in  
the previous section.  
For diagrams and information about installing the inverter/charger without the XW  
Conduit Box and XW Power Distribution Panel, see Appendix C.  
Important: Communication and signal cables must be segregated from all DC and  
AC wiring. Therefore, a small raceway has been included in the design of both the  
XW Power Distribution Panel and the XW Conduit Box to separate the  
communications cables from the power cables. This is a small raceway run built into  
the bottom of both the XW Power Distribution Panel and the XW Conduit Box and is  
held in place by a single screw at the top of the raceway.  
Installation Tip  
Before making the AC or DC cable connections, route the communications cables through  
the raceway, but do not connect them to their components until after all the inverter  
connections are made. Once the AC and DC connections are made the run becomes  
difficult to access. Use different colors for the communications cables (or cable tags) to  
help make them easier to identify.  
Route the communications cables for any  
accessories being installed BEFORE  
making AC or DC Connections.  
IMPORTANT: When routing communications cables through the XW  
Power Distribution Panel, the raceway conduit must be used to keep the  
communications cables separate from the power cables.

Step 4: Wiring the Inverter  
Batteries  
See the FAQs section of the Xantrex Web site for information on determining battery bank  
requirements.  
Consider the following recommendations for battery use.  
•
•
•
Use only the deep discharge types for inverter applications.  
Use the same battery type for all batteries in the bank.  
Use only batteries from the same lot and date in your battery bank. This information is  
usually printed on a label located on the battery.  
CAUTION: Damage to Equipment  
The XW Inverter/Charger is intended to operate with batteries as its source of DC power. Do not  
connect DC power sources, such as PV arrays, wind turbines, or micro-hydro turbines, directly to  
the XW Inverter/Charger without a battery. Connect DC power sources to a charge controller such  
as the XW Solar Charge Controller instead. If DC power sources are connected directly to the  
inverter, the DC rating of the inverter can be exceeded and the inverter can be damaged.  
Battery Bank Requirements  
The DC voltage of the inverter must match the nominal voltage of the system and all  
battery-connected devices. If the inverter is a 24-volt inverter, then the battery bank and all  
battery-connected devices in the system need to be configured for 24 volts.  
Important: The minimum recommended battery bank is 100 Ah. The inverter is designed to  
operate with batteries and should not be operated without them. Also, do not allow the battery  
bank to become completely discharged. If the voltage of the battery bank falls below 10 volts, the  
XW Power System will not operate.  
Battery Cable Requirements  
WARNING: Fire Hazard  
Undersized cables can overheat and melt, creating a fire hazard when subjected to heavy (peak)  
loads. Always use a cable of proper size and length, rated for the amperage of the inverter and  
batteries.  
Important: Use only fine-stranded copper cables for battery and inverter DC connections. Do  
not use coarse-stranded wire, as the lack of flexibility may damage battery and inverter terminals.  
Battery cable length  
Battery cable lugs  
Runs should be kept as short as practical. Length should not exceed 10 feet (3 m). For best  
performance, the positive and negative cables should run alongside each other. Avoid  
cable loops.  
Battery cables must have crimped copper compression lugs or crimped and soldered  
copper compression lugs. Soldered connections alone are not acceptable. Lugs must be  
rated for use with fine-stranded cable.  
Overcurrent  
protection  
For safety and compliance with regulations, battery overcurrent protection is required.  
Fuses and disconnects must be sized to protect the wiring in the system and are required to  
open before the wire reaches its maximum current carrying capability.

Inverter Grounding  
Important: The grounding requirements vary by country and by application. All installations  
must comply with national and local codes. Consult local and national codes for specific grounding  
and bonding requirements for the desired installation.  
Backfeed Protection Requirements  
Important: Installers must make allowance for the amount of power that can  
be fed into a distribution panel and the means and location for feed-in, in  
accordance with NEC 2005 article 690.64 or similar requirements of the local  
electrical code.

Inverter/Charger Installation  
Wiring the Inverter to the XW Power Distribution Panel  
Important: If a XW Conduit Box is installed, communication and Battery Temperature Sensor  
cables must run through the raceway at the rear of the XW Conduit Box. Before making AC and  
DC connections, route all communication and Battery Temperature Sensor cables through the  
raceways. The raceways becomes more difficult to access after all AC and DC wiring is completed.  
Grounding the DC System  
The inverter’s chassis ground bar (see Figure 2-7) is used to connect the chassis of the  
inverter to the DC grounding system. The terminal accepts wires from #14 AWG to  
#2 AWG.

Step 4: Wiring the Inverter  
Installing the Battery Temperature Sensor  
The Battery Temperature Sensor (BTS) port is for connecting to the Battery Temperature  
Sensor, which regulates battery charging based on battery temperature. Installing a sensor  
extends battery life by preventing overcharging in warm temperatures and undercharging  
in cold temperatures. This port is also considered part of the DC interface (see Figure 2-9).  
To install the Battery Temperature Sensor:  
1. Pass the end of the Battery Temperature Sensor cable through a conduit hole and insert  
the Battery Temperature Sensor plug into the Battery Temperature Sensor port.  
2. Route the cable to the battery enclosure and connect the ring terminal on the Battery  
Temperature Sensor directly to a battery terminal (recommended), or use the adhesive  
backing on the sensor back to attach the sensor to any side of the battery to be  
monitored.  
If using the adhesive backing, install the Battery Temperature Sensor on the side of the  
battery below the electrolyte level. It is best to place the sensor between batteries and  
place the batteries in an insulated box to reduce the influence of the ambient  
temperature outside the battery enclosure.

Inverter/Charger Installation  
Making AC Connections  
This section describes how to make AC connections between the XW Inverter/Charger  
and the XW Power Distribution Panel (using the pre-installed AC wiring in the XW Power  
Distribution Panel) and between the XW Power Distribution Panel and the AC distribution  
panel, or sub-panel (using wiring provided by the installer). See Appendix C, “Alternate  
System Configurations” if the installation will not be including an XW Power Distribution  
Panel.  
CAUTION: Damage to the Inverter  
The inverter’s AC output must never be wired to the utility or generator output. This will cause  
severe damage to the inverter which is not covered under warranty.  
Do not use a GFCI equipped AC source to power either the grid or generator inputs. The  
AC input filters on the XW may cause nuisance tripping of ground fault protected outputs.  
AC Connections and Communication Ports  
AC Connections  
The AC terminal block includes three terminals each (L1, L2 and Neutral) for AC Grid  
input, AC Generator input, and AC Load connections. The neutrals are connected to each  
other, requiring only one neutral connection when installed with an XW Power  
Distribution Panel. Without the XW Power Distribution Panel, additional neutral  
connections may be required at the input sources.  
Communication  
Ports  
Four communications ports and one AUX Port are located on the bottom of the inverter  
and support the following features.  
•
•
The two AC sync ports are used for connecting multiple inverters in parallel.  
The two Xanbus ports are used for network connections between inverters, charge  
controllers, and accessories.  
•
The AUX port provides 12 Vdc/250 mA output to control a relay, fan, indicator light  
or other device. The auxiliary output can be configured (using a XW System Control  
Panel) to trigger in response to low- or high-battery voltage or high- or low-battery  
temperature. The auxiliary output can also be triggered manually using a XW System  
Control Panel.

Inverter/Charger Installation  
Grounding the AC System  
Important: Place the Neutral-to-ground bond in a permanently installed AC distribution panel  
that is part of the system. This may be a main panel or a sub-panel.  
See Table 2-4 on page 10 for torque values for the AC terminal and AC Ground bar.  
See Figure 2-8 on page 2–11 for torque requirements for the ground bar in the XW Power  
Distribution Panel.  
Actual ground requirements may vary.  
* Depending on the location of the generator and  
local code requirements, the generator disconnect  
may be located in the power distribution panel.  
In an off-grid installation (i.e., where no utility grid is available), the  
generator can be connected to the breakers provided in the XW Power  
Distribution Panel. No additional breaker is required.

Step 4: Wiring the Inverter  
AC Wiring to the Inverter AC Distribution Panel  
An inverter AC distribution panel (also known as a sub-panel or inverter load panel) and  
AC conduit must be installed before AC wiring is connected to the inverter.  
Install the inverter AC distribution panel and conduit as follows:  
1. Determine the location for the inverter AC distribution panel and install it according to  
the manufacturer’s directions.  
2. Install an AC conduit between the XW Power Distribution Panel and the inverter AC  
distribution panel.  
3. Determine which circuits the inverter will power and install the appropriate circuit  
breakers into the inverter panel.  
4. For On-Grid systems:  
a) Disconnect all power to the main utility panel.  
b) Determine which circuits will be backed by the inverter(s) and remove their wires  
from the main panel.  
c) Reroute these wires to the new inverter subpanel.  
5. Remove unused breakers from utility panel. It is now safe to re-energize the main  
utility panel.  
6. Install a 60-amp maximum (disconnect) main circuit breaker in the inverter panel.  
This will later be wired to the inverter’s output.  
WARNING: Shock Hazard  
Before making any electrical connections, ensure both the AC and DC disconnect devices are in the  
OPEN (disconnect) position.  
CAUTION: Equipment Damage  
Verify that only one neutral/ground bond exists in the system. Having more than one neutral to  
ground bond in a system violates local electrical codes, may create a shock or fire hazard, and may  
cause some sensitive equipment to malfunction.  
CAUTION: Damage to the Inverter  
The inverter’s AC output must never be wired to the utility or generator output. This will cause  
severe damage to the inverter which is not covered under warranty.  
AC Wiring to the XW Power Distribution Panel  
To connect the XW Power Distribution Panel to the inverter:  
Important: The XW Inverter/Charger is provided with fixed disconnect limits for voltage and  
frequency. These limits are fixed when the unit is exporting power to the grid. The unit shall not be  
aggregated such that it can export more than 30 kW on a single point of common connection.  
Important: Both lines of input power must be connected in order for the XW Inverter/Charger to  
operate. For example, L1 and L2 of Grid Input and/or L1 and L2 of Gen Input need to be connected.  
1. Connect the wires labelled “INV1 N-LOAD (SPLIT PHASE)”, “INV1 L1-LOAD,  
and “INV1 L2-LOAD” (from the L1 and L2 terminals on the input (top) side of the  
output breaker and the neutral bus) to the AC Load (L1-LOAD, N-LOAD, L2-LOAD)  
terminals on the inverter. Connect the neutral wire first to the N-LOAD terminal.

Inverter/Charger Installation  
2. Connect the wires labelled “INV1 L1-GRID” and “INV1 L2-GRID” to the inverter. If  
the AC source will be the utility grid, connect to the GRID (AC1) terminals  
(L1-GRID, L2-GRID). If the system will be off-grid and the only AC source will be a  
generator, these wires can be connected to the GEN (AC2) terminals (L1-GEN,  
L2-GEN). No additional neutral connection is needed when using the XW Power  
Distribution Panel. (Additional neutral terminals (N-GRID, N-GEN) are provided on  
the inverter for installations that do not use the XW Power Distribution Panel.)  
3. Connect L1 (from the L1 output Power Distribution Bar) and L2 (from the L2 output  
Power Distribution Bar), Neutral, and Ground to the sub-panel that supplies power to  
inverter loads.  
4. Connect L1 and L2 from the input side of the AC1 Breaker (L1 and L2 Power  
Distribution bars) to the utility grid AC Panel. Connect Neutral from the XW Power  
Distribution Panel to the utility grid AC panel. Connect the ground wire between the  
XW Power Distribution Panel and the utility grid AC panel.  
Power Distribution bars in the XW Power Distribution  
Panel accept up to a #2/0 AWG cable (maximum).

Basic Functional Test - Single Inverter  
Basic Functional Test - Single Inverter  
The following steps will complete a basic functional test of the XW Inverter/Charger. If  
any test fails, please refer to the Troubleshooting section in the XW Inverter/Charger  
Operation Guide for assistance.  
Confirm All Connections  
Once the AC and DC wiring have been installed and connected, take a moment to go back  
over all connections and make sure they are secure and have been installed correctly.  
Applying DC Power to the Inverter  
CAUTION: Reverse Polarity Damage  
Before making the final DC connection or closing the DC breaker or disconnect, check cable  
polarity at both the battery and the inverter/charger. Positive (+) must be connected to positive (+).  
Negative (–) must be connected to negative (–).  
Reverse polarity damage is not covered by warranty.  
To apply DC power to the inverter:  
1. Before applying DC power to the inverter, measure the voltage and polarity of the  
cables (measure at the battery side of the disconnect or breaker).  
Important: Voltage should be between 40 to 60 volts for a 48-volt  
system, and 20 to 30 volts for a 24-volt system. If the DC voltage is low,  
the battery bank needs to be charged externally. Charge the battery bank  
and restart the functional test.  
2. Apply battery (DC) power to the inverter by closing the battery bank DC disconnect.  
The inverter will power up, the display will illuminate, but the inverter will remain in  
the Standby Mode (as shown in Figure 2-19).  
Note: If the inverter was  
previously powered up then it will  
power-up in the last operating  
state (Operating or standby)  
All LEDs temporarily illuminate.

Inverter/Charger Installation  
Enable the Inverter  
CAUTION: Equipment Damage  
Prior to activating the inverter, ensure that all AC loads are disconnected from the output of the  
inverter.  
By default, Invert Mode is enabled and the unit should start inverting upon transitioning  
from Standby Mode. If Invert Mode is disabled, the display will show (---) once out of  
Standby Mode. If the unit powers up in Standby Mode, prese the ON/OFF button  
momentarily to change the mode from Standby to Operating.  
To enable the inverter:  
◆ Press the inverter ON/OFF button and the Equalize button at the same time. “En” is  
briefly displayed on the inverter panel to indicate the inverter is enabled.  
To disable the inverter:  
◆ Press the inverter ON/OFF button and the Equalize button at the same time. “diS” is

Figure 2-20 Enable the Inverter  
3. Monitor the INVERT (Green kW) LED to confirm which mode the inverter is in:  
•
LED Off – Invert Mode is disabled. The inverter/Charger is not powering the AC  
loads. However, if good AC is present, it is passed through to the loads.  
•
One blink/sec – The inverter/charger is in the Search Mode and is looking for an  
AC load greater than the Search Watts setting (default = 25 watts). The Display  
shows Sch (Search) when this mode has been enabled.  
•
LED On – The inverter/charger is on. The inverter is operating and is able to  
provide power to the AC loads. This is the default mode on initial powerup once  
the unit is taken out of Standby Mode.  
If the inverter is not operating or the INVERT LED (kW) does not illuminate, check all  
connections. Check the inverter’s DC voltage on the positive (+) and negative (–)  
terminals. Check the Fault LED. If the fault LED is illuminated, check for a fault code on  
the information panel. Correct the reported fault if possible and clear the fault. If the DC  
voltage is low, the battery bank needs to be charged externally. Charge the battery bank  
and restart the functional test.

Basic Functional Test - Single Inverter  
AC Voltage Check  
Important: This test requires the use of a voltmeter.  
To perform an AC voltage check:  
1. With the inverter on (INVERT [green, kW] LED on solid), verify the AC voltage at  
AC Loads block terminal L1-Load to N-Load.  
2. Verify that neutral is bonded to ground in the system by measuring the hot and neutral  
voltages relative to ground. Neutral-to-ground should equal zero (0) volts.  
3. After confirming the correct AC voltage, turn on your AC output breaker and place a  
load on the inverter (plug in a light or other load to an outlet the inverter is powering).  
4. Confirm that the AC load that was just applied works properly.

Confirming Battery Charger Operation  
To confirm battery charger operation:  
1. Apply AC from grid or generator, confirm voltage.  
2. Check LEDs (AC1 or AC2) on the front panel. One of them must be illuminated for  
the unit to charge. Check the “A” LED. If the “A” LED is illuminated, the unit is  
charging and the battery current is displayed on the information panel.  
Amp LED  
Figure 2-22 Checking Charging Operation  
Important: Unless the inverter/charger settings have been changed, the inverter will charge as  
if it has a large (> 440 Ah) flooded battery bank (factory default setting). Therefore, ALL systems  
may need to have the battery charging set points “fine tuned” to avoid damage to the batteries.  
This completes the functional test. If all tests pass, the inverter is ready for use. If any of  
the inverter’s internal set points need to be adjusted, consult the configuration chapter of  
the operation guide.

Basic Functional Test - Multiple Inverters  
The following steps will complete a basic functional test of multiple XW Inverter/  
Chargers. If any test fails, please refer to the Troubleshooting section in the XW Inverter/  
Charger Operation Guide for assistance.  
To perform a functional test on multiple inverters:  
1. Check/verify all wiring and cable connections.  
2. Measure DC voltage at the DC terminals on the inverter and confirm its within range  
and has correct polarity. The acceptable range is >20 Vdc for 24 V system or >40 Vdc  
for 48-V Systems.  
3. Switch INV1 DISCONNECT to ON position.  
4. Check inverter display for startup self-test during which all LED's will flash  
momentarily. Once self-test is complete, inverter will display "Stb". (The Fault/  
Warning LED may flash for a few seconds but eventually will turn off. If Fault/  
Warning LED persists, check to ensure battery temperature sensor is connected. Also,  
if the inverter has been pre-configured, it may go straight into normal operating  
mode.)  
5. Using the XW System Control Panel, set First (Master) Inverter Device Number  
a) Go to the inverter’s Advanced Settings menu by pressing Down arrow + Enter  
from System Status screen and then simultaneously pressing Enter + Up arrow +  
Down arrow.  
b) Select Multi Unit Config menu.  
c) Change Dev Number from “00” to “01”. The inverter will now appear as  
XW6048-01 in the device list.  
d) Press Exit to go back to the System Status screen.  
6. Switch INV2 DISCONNECT to ON position.  
7. Check inverter display for startup self-test during which all LED's will flash  
momentarily. Once self-test is complete, inverter will display "Stb". (If the inverter has  
been pre-configured, it may go straight into normal operating mode or display F66  
warning.)  
8. Using the XW System Control Panel, set Second (Slave) Inverter Device Number and  
Inverter Mode.  
a) Select new inverter XW6048-00 in the device list.  
b) Go to the inverter’s Advanced Settings>Multi-Unit Config menu.

17. Disconnect AC LOAD breakers.  
18. Using the XW System Control Panel, reduce Maximum Charge Rate.  
a) From System Status screen, go to System Settings and enable Cascading (if not  
enabled). With Cascading enabled, a change to a setting in one inverter will auto-  
matically ripple through to the other inverter(s) in the system.  
b) Go to Advanced Settings>Charger Settings in one of the inverters.  
c) Set Max Chg Rate to 10%.  
d) Press Exit until you see the System Status screen.  
19. Switch AC Input breakers ON. Note - all inverters in the system must be connected to  
the same AC Input source before they will qualify the source.  
20. Confirm both inverters start charging. Note -- With the Max Chg Rate set to 10% the  
maximum charge rate is limited to 10 A on each inverter. Depending on the battery  
bank’s state-of-charge, the output from one or more inverters may quickly drop to  
zero. This is considered normal operation.  
21. Check for faults. If fault condition(s) exist, correct and restart Functional Test.  
If the Inverters pass the Functional Test, proceed to Commissioning procedure as defined  
in XW Inverter/Charger Operation Guide.

Accurate. Digital information is less susceptible to interference and line loss.  
The Xanbus System  
What is a network?  
A network is a collection of devices that perform individual functions, but also  
communicate and interact with the other devices. The network capability of the XW  
Power System provides a robust, integrated product solution that simplifies and automates  
the installation, configuration, control, monitoring, and integration of devices that deliver  
and distribute AC or DC power.  
Network  
components  
Each device is integrated into the network using cables, network connectors, and  
terminators. An example of a network-managed power system is shown in Figure 3-1.  
Figure 3-1 Network-Managed Power System  
Network  
The network can be installed in one of two configurations: as a multi-drop backbone (see  
configurations  
Figure 3-5) or as a daisy chain (see Figure 3-6).

The Xanbus System  
Network Components  
A Xanbus network consists of the following components:  
•
Xanbus-enabled devices—these include the XW System Control Panel, the XW  
Inverter/Charger, XW Automatic Generator Start, and XW Charge Controller. The  
maximum number of Xanbus devices connected to a single Xanbus network should  
not exceed eight devices.  
•
Xanbus power supply—the network must have at least one device with a power supply  
to run the network. The total network current supplied by all the power-sourcing  
devices must be greater than or equal to the total current drawn by the power  
consuming devices. The power supply must be capable of providing 15 Vdc/200 mA  
to each device. The XW Inverter/Charger can provide sufficient network power.  
For example, in a system with an inverter/charger, a XW System Control Panel and an  
Automatic Generator Start, the inverter/charger is a power-sourcing device capable of  
providing 800 mA at 15 Vdc while the two other devices each consume a maximum of  
200 mA for a total maximum consumption of 400 mA. In this example, the network is  
properly configured from a power perspective because the power source is capable of  
providing more current than is needed: 800 mA > 400 mA.  
Important: See the specifications for each Xanbus device to determine how much power each  
device consumes or supplies.  
•
Xanbus cables—each Xanbus-enabled device is connected by a Category 5 (CAT 5 or  
CAT 5e) cable, a standard cable available from Xantrex or any computer supply store.  
The cable consists of eight conductors in four twisted pairs with an RJ45 modular  
connector wired to the T568A standard.  
CAUTION: Equipment Damage  
Do not use crossover cable.  
Table 3-1 contains the arrangements of wire colors to pin numbers for the T568A  
standard.

Network terminators (Figure 3-3)—the Xanbus network must be properly terminated  
at each end with male or female network terminators to ensure the communication  
signal quality on the network. If the network is not properly terminated, signal quality  
is degraded and performance on the network is reduced. Permanent configuration  
without terminators is not supported by Xantrex. The XW Series and other  
Xanbus-enabled devices ship with one male terminator already installed. Depending  
on your network layout, this terminator may need to be removed and inserted into  
another device elsewhere in the network.  
Female network terminator  
Male network terminator

•
Network connectors—The three-way connector houses three RJ45 inputs that provide  
a device connection point on a multi-drop backbone layout (see “Multi-Drop  
Backbone Layout” on page 3–5). All three inputs are wired identically and can accept  
either Xanbus cables or terminators. One input is available for connecting to a  
Xanbus-enabled device. The remaining inputs are reserved for connection to other  
network connectors, a Xanbus cable terminated with a female terminator, or a male  
terminator.  
The network connector is mounted to a bulkhead or a wall, as shown in Figure 3-4.

Network Layouts  
Xanbus-enabled devices can be connected in one of two Xanbus network layouts:  
multi-drop backbone or daisy chain. Each network layout has advantages and  
disadvantages, depending on the application and/or environment. It is up to the installer or  
system designer to decide which layout is best for the installation.  
Important: Do not mix the two types of network layouts. Mixed configurations are not  
supported by Xantrex.  
Multi-Drop Backbone Layout  
In a multi-drop backbone layout, each Xanbus-enabled device on the network is connected  
by a drop cable to the network bus or backbone with a network connector, as shown in  
Figure 3-5.  
Terminators are required at both ends of the multi-drop backbone cable, as shown in  
Figure 3-5. Therefore, the Xanbus-enabled devices do not require their own termination.  
With only one terminator, the signal quality is degraded and performance on the network is  
reduced. Permanent configuration with only one terminator is not supported by Xantrex.  
If cables are placed at the end of the network, female terminators are required. Otherwise,  
male terminators can be inserted directly into the open jack of each network connector at  
the end of the network.  
Advantages In this layout, Xanbus-enabled devices can be removed or replaced while  
still keeping the network operating.  
Disadvantage The main disadvantage of this layout is the cost of the network  
connectors (a daisy chain layout uses no network connectors). Each device in this layout  
requires its own network connector.

Figure 3-5 Multi-Drop Backbone Layout  
Daisy Chain Layout  
In a daisy chain layout, each device on the network is linked with separate lengths of  
Xanbus cable, as shown in Figure 3-6. This layout does not require network connectors.  
As in the multi-drop backbone layout, two terminators are required to ensure the  
communication signal quality on the network. The Xanbus-enabled devices at each end of  
the chain must have a male terminator inserted into their open network ports.  
Advantage The advantage of this layout is that it is less expensive to install because  
network connectors are not required.  
Disadvantage The disadvantage of the daisy chain layout is that Xanbus-enabled  
devices cannot be removed from the network without interrupting the network. To make  
the network function after removing a device, you must connect the Xanbus-enabled  
devices on either side of the missing device to each other or replace the device.

bends in the cable—no less than a 4-inch (100 mm) radius.  
•
Allow at least 2 ¼ inches (57 mm) of space behind the wall to accommodate the depth  
of the unit and allow room for the cables to bend.  
•
•
•
Allow for some slack in the cable tension.  
Keep the alignment of wire pairs inside the sheath as straight as possible.  
Allow separation between data and power cables (data cables should only cross a  
power cable at right angles).  
•
•
Do not staple the cable with metal cable staples. Use appropriate hardware fasteners to  
avoid damage to the cable.  
Support horizontal cables using J hooks or cable trays.

XW Solar Charge Controller Installation  
Installing the Charge Controller  
This chapter describes installing the XW Solar Charge Controller with the XW Power  
System, including the power distribution panel. For stand-alone installation, see the XW  
Solar Charge Controller Owner’s Guide.  
PV Array Requirements  
Each Charge Controller must be connected to its own PV array. For optimum  
performance, each individual array must be composed of the same type of solar panel,  
with the same Voc and Vmp specifications.  
Important: The following information provides only general guidelines. The installation and  
rated performance of your PV array is subject to inspection and approval by the authority having  
jurisdiction.  
Array Size  
For PV array sizing guidelines, use the XW Solar Charge Controller PV array sizing tool  
accessible from www.xantrex.com/support.  
Although the Solar Charge Controller can harvest a maximum of 3500 W, the PV array  
size can be as large as 6720 W (based on 48 A × 140 Vdc = W).  
Array Voltage  
CAUTION; Equipment Damage  
The PV array voltage must never exceed 150 Voc (open circuit voltage) under  
any conditions.  
The maximum PV array voltage for XW Solar Charge Controller MPPT operation is  
140 Vdc.  
When calculating PV array size for the XW Solar Charge Controller, consider the  
expected Voc of the array under all possible conditions. Panel voltage increases with  
decreasing temperature. The array needs to be sized so that 150 Vdc does not occur, even  
at the lowest expected panel temperature during open circuit. The panel manufacturer  
provides a Voc rating per panel, but it is usually rated at 25 °C (77 °F).  
Array Current  
Important: The I (short circuit current) rating of the array must not exceed  
sc  
the 60 A input current rating of the XW Solar Charge Controller at any time.  
Panels rated up to 48 A at 25 °C (77 °F) are recommended to allow for increases in Isc at  
low panel temperatures and at solar noon. Ensure that the Isc rating under all conditions  
does not exceed 60 A. A factor of 1.25 is applied to the rated Isc at 25 °C (77 °F) when the  
panel is colder than -21 °C (70 °F).

Mounting  
MPPT Voltage Range  
The XW Solar Charge Controller maximum power point tracking algorithm maximizes the  
output power of PV arrays as long as the operating voltage is within the MPPT operational  
window. Ensure that the PV array used in the system operates within the MPPT  
operational window.  
Effects of array voltages outside of the MPPT operational window are shown in Table 4-1.

Mounting  
The instructions in this section apply to an installation including the power distribution  
panel. Installation procedures will vary according to your specific application. For special  
applications, consult a qualified electrician or your Xantrex Certified Dealer.  
Important: Installations must be compliant with all local electrical codes. Installation of this  
equipment should only be performed by a qualified electrician or by a Certified Renewable Energy  
(RE) System installer.  
Choosing a Location  
The XW Solar Charge Controller is designed to be mounted vertically to the side or the top  
of the power distribution panel.  
The XW Solar Charge Controller must be installed indoors in a dry, protected location  
away from flammable materials, sources of high temperature, moisture, and vibration, and  
direct sunlight. The location must also be sheltered from direct sunlight, rain, snow, and  
wind-blown debris.  
CAUTION: Equipment Damage  
Never install the XW Solar Charge Controller where it is exposed to salt water spray. Exposure to  
salt water will void the warranty and may cause a malfunction or a shock hazard.

XW Solar Charge Controller Installation  
WARNING: Explosion/Corrosion Hazard  
To reduce the risk of fire or explosion, do not install the XW Solar Charge Controller in sealed  
compartments containing batteries or in locations that require ignition-protected equipment.  
To reduce the risk of corrosion from hydrogen-sulfide gas vented by batteries, do not install the XW  
Solar Charge Controller in sealed compartments containing batteries.  
If using “sealed” batteries, the controller can be mounted in the same enclosure as long as  
it is adequately ventilated.  
For optimal and safe operation, ensure there is adequate clearance around the XW Solar  
Charge Controller. See Table 4-2. If clearances are reduced below these minimums, rated  
performance may not be achieved.

XW Solar Charge Controller Installation  
Grounding  
The XW Solar Charge Controller is designed to work only with negative-grounded  
electrical systems. Grounding for both PV and battery circuits is provided inside the  
wiring compartment. Each ground connection can accommodate up to #6 AWG wire size.  
A fuse rated at 1 A, 600 V (accessible from inside the wiring compartment) grounds the  
negative conductor of the PV array and provides PV ground-fault protection (PV-GFP).  
Replace with Littelfuse KLKD 1 or equivalent.  
Important: Only one Charge Controller is to have the PV-GFP fuse installed in  
installations with multiple parallel XW Series. Before mounting and connecting the XW  
Seriess, remove the PV-GFP fuse from each unit except one.  
WARNING: Shock Hazard  
Do not connect the battery negative to ground. NEC requirements specify that the battery  
negative ground must be done only through the 1A PV-GFP fuse. Bonding the battery  
negative to ground disables PV ground-fault protection. The battery compartment must  
only be grounded if it is metal.  
WARNING: Fire Hazard  
Ensure there is no other ground connection in the DC  
wiring or the PVGFP will be defeated and will not protect  
the array from ground fault conditions.

Wire Size and Over-current Protection Requirements  
The wiring, over-current protection devices (fuses and circuit breakers), and installation  
methods used must conform to all national and local electrical code requirements.  
Wiring must be protected from physical damage with conduit or a strain relief clamp.  
The BTS, auxiliary output, and network cables must pass through a different conduit than  
the conduits used for PV wiring and battery cables. Pull the BTS cable through the conduit  
first as the connector may not fit if other wires have been pulled first.  
Current rating  
The XW Solar Charge Controller is rated for 60 A maximum Isc. Since PV outputs can  
vary due to the array size or sunlight striking it, the safe minimum wire size must be  
chosen for maximum array short-circuit current. Consult PV array manufacturer  
specifications.  
Minimum wire  
gauge  
For installations where the PV array output is the maximum allowable 60 A Isc, the  
minimum allowable wire gauge is #6 AWG (13.3 mm2) copper wire with a 90 °C (194 °F)  
insulation rating. This wire gauge is determined by electrical code requirements regarding  
conduit knockout sizes, wire bending radius, and space available within the XW Solar  
Charge Controller wiring compartment.  
No crimp-on terminals or lugs are required.  
Over-current  
protection  
Over-current protection must be installed for the battery and PV circuits to protect the XW  
Solar Charge Controller from short circuits at its input and output. The NEC requires all  
circuits to be protected with a device rated for 125% of the rating of the circuit.

Battery Circuit  
The DC-rated fuse or circuit breaker between the battery and the XW Solar Charge  
Controller must have a maximum size of 1.25 × 60 A (the maximum current rating of the  
XW Solar Charge Controller). That is, the fuse or circuit breaker must be rated equal to or  
above 75 A.  
PV Circuit  
The DC-rated fuse or circuit breaker between the PV array and the XW Solar Charge  
Controller must be rated for the Isc of the array but will not exceed the 60 A rating.  
Long-distance wire  
runs  
If there is a significant distance between the PV array and the XW Solar Charge Controller  
or between the XW Solar Charge Controller and the battery, larger wires can be used to  
reduce the voltage drop and improve performance. Refer to Table 4-4 or Table 4-5.  
WARNING: Equipment damage  
Do not connect an array capable of delivering over 60 A I to the XW Solar Charge Controller.  
sc  
Wires larger than #6 AWG can be used only to reduce power loss in the wiring.  
To use a larger size wire, use a splicer block (terminal block) approved and rated for this  
application. This allows the larger cable size from the batteries to be “spliced” to the #6  
AWG wire connected to the XW Solar Charge Controller. The splicer block must be  
installed outside of the XW Solar Charge Controller wiring compartment.  
Follow manufacturer’s recommendations for torque and mounting. Splicer blocks and  
split-bolt kerneys are available from renewable energy suppliers.  
Important: Local and national electrical codes must be followed for determining additional  
installation requirements.  
Larger wire sizes may be used to improve performance, but may not be installed directly into this  
Charge Controller. Use a splicer block as previously described.  
Maximum one-way  
distance and wire  
size  
Refer to Table 4-4 or Table 4-5 and find the maximum current in the left column, and the  
one-way distance from the PV array to the XW Solar Charge Controller (or the distance  
from the XW Solar Charge Controller to the battery) on the same line, then read the wire  
size required at the top of the column.

XW Solar Charge Controller Installation  
Connecting the XW Solar Charge Controller to the Distribution Panel  
WARNING: Shock Hazard  
Whenever a PV array is exposed to light, a shock hazard exists at the output wires or exposed  
terminals. To reduce the risk of shock during installation, cover the array with an opaque (dark)  
material before making the connections. PV arrays generate voltage whenever light strikes the  
surface of the array. Before connecting the XW Solar Charge Controller, cover the array to prevent  
any current from being generated.  
WARNING: Shock Hazard  
Do not connect the battery negative to ground. Bonding the battery negative to ground disables PV  
ground-fault protection.  
To connect the XW Solar Charge Controller:  
1. Connect the PV array’s positive (+) output to the PV array disconnect.  
2. Route another (+) cable from the other end of the PV disconnect to the terminal  
marked PV + in the XW Solar Charge Controller.  
3. Connect the PV array’s negative (–) output to the terminal marked PV – in the XW  
Solar Charge Controller.  
4. Connect a positive (+) cable from the terminal marked BAT + to the battery disconnect.  
5. Connect a second positive (+) cable to the other side of the battery disconnect and  
connect to the positive (+) battery terminal.  
6. Connect the negative (–) battery cable to the terminal marked BAT – in the XW Solar  
Charge Controller.  
7. Torque the Charge Controller terminals as follows.  
•
•
•
15 inch-pounds (1.7 Nm) for #14–10 AWG wire  
18 inch-pounds (2.0 Nm) for #8 AWG wire  
20 inch-pounds (2.2 Nm) for #6 AWG wire.  
Be careful not to overtighten. Allow some slack on the cables within the controller and  
secure the wiring with strain reliefs or cable clamps.  
See Figure 4-8.

XW Solar Charge Controller Installation  
Commissioning  
During commissioning, the XW Solar Charge Controller prompts the installer to enter  
important system information such as the nominal battery voltage, battery type, and  
battery bank capacity. Ensure the system information is available prior to commissioning.  
If a XW System Control Panel is present, the XW System Control Panel is intended to be  
the configuration interface, so the prompt screens are suppressed. If you prefer to  
configure using the prompt screens, disconnect the Xanbus cable connecting the XW  
System Control Panel from the XW Solar Charge Controller before powering up for the  
first time.  
Configuration Screens  
When power is first applied to the XW Solar Charge Controller, several configuration  
screens prompt you to enter the following information:  
•
A “DC out” (battery) connection, which enables the XW Solar Charge Controller to  
read and share the same battery information with other Xanbus-enabled devices that  
charge or invert from the same battery bank.  
•
Battery type: Flooded (default), Gel, AGM, Custom.  
If you select Custom, the settings for battery type match the default settings for  
Flooded batteries until you reconfigure the settings on the Custom Battery menu.  
•
•
Nominal battery voltage of the battery bank connected to the XW Solar Charge  
Controller.  
The XW Solar Charge Controller automatically detects battery voltages of 12 V, 24 V  
and 48 V. If your nominal system voltage is 36 V or 60 V, enter the correct system  
voltage on this screen.  
Battery bank capacity, in amp-hours.  
Commissioning Units Using a XW System Control Panel  
In systems where an XW System Control Panel (SCP) is present, the SCP is intended to be  
the configuration interface. For information about SCP navigation and menus, see  
Appendix B, “XW System Control Panel Menus in the XW Inverter/Charger Operation  
Guide.  
Commissioning units using an SCP involves three separate procedures:  
1. Setting the Device Numbers for all XW Solar Charge Controllers.  
2. Configuring Connections and Charger Settings for the first XW Solar Charge  
Controller.  
3. Copying settings from the first unit to the other XW Solar Charge Controller.  
To set the Device Numbers for all XW Solar Charge Controllers:  
1. Ensure power is applied to the XW System Control Panel.  
2. Close the DC disconnect or use a selector switch to apply battery power to all of the  
XW Solar Charge Controllers at the same time. When the XW Solar Charge  
Controllers are powered up, they will detect that an SCP is already operating on the  
network, and be ready for configuration through the SCP. Do not apply PV power at  
this point.

Commissioning  
3. From the Select Device menu on the SCP, select a XW Solar Charge Controller (each  
unit should appear as “MPPT60 00” where the 60 stands for 60A, and the 00 is its  
device number).  
4. On the MPPT Setup menu, ensure the Advanced Settings item is displayed. If  
Advanced Settings are not displayed (and Basic Settings appears as the last item on the  
menu), press the up arrow, down arrow and Exit keys together. (See “Advanced menu”  
on page B-7 of the XW Inverter/Charger Operation Guide.)  
5. Select Advanced Settings, then select the Multi Unit Config menu. After entering the  
Multi Unit Config menu, the LCD backlight on the XW Solar Charge Controller to be  
configured will flash.  
6. On the Multi Unit Config menu, select Dev Number and set it to a number other than  
00.  
The device number can be set to any number between 01 and 31. For the first XW  
Solar Charge Controller, 01 is recommended. If you have two charge controllers,  
simply set them to 01 and 02.  
7. Press Exit until the Select Device menu is displayed.  
The XW Solar Charge Controller now appears as MPPT60 01 on the menu.  
8. Repeat steps 3 through 7 for the next XW Solar Charge Controller.  
When you have set the device number for all XW Solar Charge Controllers, you can  
configure Connections and Charger Settings for the first XW Solar Charge Controller.  
To configure Connections and Charger Settings for the first XW Solar Charge  
Controller:  
1. On the Select Device Menu, select “MPPT60 01.”  
2. Navigate to the Multi Unit Config menu and select Connections.  
On the Connections menu, you can configure PV In (PV input) and DC Conn (DC  
output, or the battery bank). If the system has only one battery bank, leave DC Conn at  
the default setting. The PV In setting allows you to differentiate which array is going  
to which XW Solar Charge Controller. This setting is used for status reporting only,  
not for any internal controls. Setting PV In to a non-default value is optional.  
3. Press Exit twice to leave the Connections menu and Multi Unit Config menu.  
4. From the Advanced Settings menu, select Charger Settings.  
5. Set the Battery Type, Battery Capacity, and any other charger settings required for  
your system.  
While in the Charger menu, ensure that the Nominal Battery Voltage is set correctly (it  
is shown as Batt Voltage and appears as the last item on the menu). If you select  
“Custom” for your Battery Type, you can further configure the Bulk, Absorption,  
Float and other settings for the charge cycle.  
The first charge controller should now be configured properly for your system.  
If multiple charge controllers are installed, you can now copy the first unit’s  
configuration over to other units.  
To copy the XW Solar Charge Controller setup to another unit:  
1. On the SCP, press Exit to leave the Advanced Settings menu and view the Select  
Device menu.  
2. On the Select Device Menu, select the next XW Solar Charge Controller for  
configuration.

3. On the Advanced Settings menu, select Copy From, then select the XW Solar Charge  
Controller you want to copy from. You should select the unit with the device number  
that matches the first unit you configured.  
4. Press Enter.  
The settings are automatically copied from the selected unit.  
Note: The Copy From command will not give you any indication that it has completed  
its task. However, you can quickly check for yourself that the charger settings you have  
chosen have been copied properly by viewing some of the settings you originally  
configured.  
5. Uncover the PV array and/or apply power with the disconnect or selector switch.  
The XW Solar Charge Controller starts up in sleep mode and waits for a short period to  
determine that the input voltage is greater than the output voltage. After the input voltage  
exceeds the output voltage by the required margin for 10 seconds, the unit begins  
operating.

XW System Accessories Installation  
The XW System Control Panel  
The XW Series Inverter/Charger can be controlled remotely by connecting a XW System  
Control Panel. The XW System Control Panel is optional for single inverter systems. The  
XW System Control Panel is required for configuring systems with multiple inverters. The  
XW System Control Panel allows access to programming features of the inverter and  
allows the system to be modified to specific installation requirements.  
The XW System Control Panel is connected to the inverter through one of two Xanbus  
ports.  
Figure 5-1 XW System Control Panel Xanbus Port Locations  
The XW System Control Panel is designed to be wall mounted (see “Mounting the XW  
System Control Panel” on page 5–3), and requires no connections other than the network  
cables or terminators that plug into the back of the unit.  
Because you cannot access the XW System Control Panel network inputs after the unit is  
mounted, the network cables need to be routed through the wall and connected before  
securing the XW System Control Panel.  
See Chapter 3, “Xanbus Network Installation”, for more information about installing a  
Xanbus-enabled device as part of a network-managed power system.

Connecting the Generator  
To connect the XW Automatic Generator Start to a generator, you must identify the start  
wiring configuration of the generator you want to use. Generators must be auto-start  
capable, and generators equipped with remote operation connections are ideal.  
If the generator is equipped for remote operation, you must examine the wiring of the  
remote cable and connector (or read your generator’s documentation, if available) and  
identify the following wires:  
•
•
•
•
Ground  
Start  
Stop  
Generator run signal, also known as the Hour Meter or Switched B+ (battery positive)  
Wiring  
requirements  
To wire the XW Automatic Generator Start to the generator, you need #16 or #18 AWG  
wire connected between contacts 12 to 20 on the wiring harness. How many of these wires  
you connect and in which combination depends on your generator type.  
Generator types  
The XW Automatic Generator Start has 13 preset generator configurations, or “Gen  
Types” (see the XW Automatic Start Owner’s Guide for details on Generator Types). To  
ensure that the XW Automatic Generator Start is compatible with your generator’s starting  
circuitry, you must select your type of generator from the XW Automatic Generator Start  
menu on the XW System Control Panel after completing the installation.

The XW Automatic Generator Start  
Important: You can only change GenType after you have put the system or the XW Automatic  
Generator Start into Standby mode. See the XW Inverter/Charger Operation Guide for instructions  
on putting the system in Standby Mode.  
This section describes the generator configurations and provides diagrams for connecting  
the wiring harness to the generator’s start wiring.  
Important: For an explanation of the terminology used in the following section, refer to  
Appendix B of the XW Automatic Generator Start Owner’s Guide. For more information about  
XW Automatic Generator Start internal relay activity and timing, see the Automatic Generator  
Start Owner’s Guide.  
Connecting the Thermostats (optional)  
Wires 1, 2, 3, and 4 on the wiring harness can be connected to two thermostats. Wires 1  
(yellow) and 2 (gray) are intended for thermostat 1 and wires 3 (orange) and 4 (gray) are  
intended for thermostat 2.

These wires connect to 12-volt/24-volt output signals from the thermostats. The XW  
Automatic Generator Start will start the generator in response to these signals.  
Thermostats can not be programmed using the XW Automatic Generator Start.  
For specific information about thermostat wiring and where XW Automatic Generator  
Start connections should be made, please consult your thermostat documentation or  
contact the thermostat manufacturer.  
Connecting an External Shutdown (optional)  
The external shutdown input is a 12-volt/24-volt input used to assure that the XW  
Automatic Generator Start keeps the generator off under conditions that may be potentially  
hazardous. Wire 5 (white/black) and 6 (gray) on the wiring harness are intended for an  
external switch or sensor (such as a moisture detector, carbon monoxide detector or coach  
running signal) that produces an active high 12-volt or 24-volt output.

XW System Accessories Installation  
Connecting an External Manual ON/OFF Switch (optional)  
The external manual ON/OFF inputs (wires 7 and 8 on the wiring harness) are intended for  
wiring to one or more remote ON/OFF switches for starting and stopping the generator  
manually. The other contact of the switch should be connected to ground. In order for the  
XW Automatic Generator Start to be able to detect these switches, wire the positive of the  
generator battery to the constant 12-volt/24-volt generator battery positive (wire 10 on the  
XW Automatic Generator Start wiring harness). See Figure 5-7.  
If the generator battery does not have the required voltage, any 12-volt or 24-volt power  
source will suit this purpose. If an alternate power source is used, the negative of the  
power source must be connect to the other contact of the switch.  
CAUTION: Equipment Damage  
Do not connect the XW Automatic Generator Start to a 48-volt battery bank. The  
XW Automatic Generator Start is limited to a 30V open-circuit maximum by its  
regulatory approval and cannot be connected to a 48-volt power source.  
Furthermore, tapping 12-volts or 24-volts from a 48-volt battery bank will  
unevenly wear out the batteries and shortens the battery bank life.

and will change its operating mode to External Manual On or External Manual Off (for  
more information, see the XW Automatic Generator Start Owner’s Guide). The XW  
Automatic Generator Start turns the generator on or off according to these inputs and the  
resulting operating mode change.  
The External Manual On and External Manual Off states are not affected by maximum  
generator run time. See the XW Automatic Generator Start Owner’s Guide for additional

Connecting an External ON/OFF LED  
Wires 9 (White/Blue) and 11 (Black) on the wiring harness can be connected to an LED or  
other light to accompany a remote external ON/OFF switch. This light turns on when the  
generator run signal is active to visually indicate that the generator is running.  
Important: With some generators, the generator run signal becomes active  
during the preheat stage, before the generator is actually running. In this case, the  
external ON/OFF LED (and the Generator On light on the XW Automatic  
Generator Start) will turn on during the preheat stage and remain on when the  
generator is running.  
For some generators, these lights will also remain on for a period of time after the  
generator has stopped.

Electrical Specifications  
XW Series Overload Capability  
Loads presented to the inverter are seldom constant. Typically, large loads are operated for  
only short periods of time. In order to provide the maximum utility, Xantrex inverters are  
allowed to operate at power levels that exceed their continuous power ratings. This graph  
shows how loads that are larger than the inverter can sustain continuously can be operated  
for useful periods of time.  
The length of time that the inverter can operate at high power is limited by temperature.  
When large loads are run, the inverter’s temperature increases. At the point where more  
heat is created in the inverter than can be dissipated, its ability to operate becomes time  
limited.
