Safety  
Explosive Gas Precautions  
WARNING: Risk of explosive gases  
Working in the vicinity of a lead-acid battery is dangerous. Batteries generate  
explosive gases during normal battery operation. For this reason, it is of utmost  
importance that each time before servicing equipment in the vicinity of the  
battery, you must read this guide and follow the instructions closely.  
1. To reduce the risk of battery explosion, follow these instructions and  
those published by the battery manufacturer and the manufacturer of  
any equipment you intend to use in the vicinity of a battery. Review  
the cautionary markings on these products and on the engine.  
2. This equipment contains components which tend to produce arcs or  
sparks. To prevent fire or explosion, do not install the inverter/charger  
in compartments containing batteries or flammable materials or in  
locations that require ignition-protected equipment. This includes any  
space containing gasoline-power machinery, fuel tanks, as well as  
joints, fittings, or other connections between components of the fuel  
system.  
Personal Precautions When Working With Batteries  
1. Someone should be within range of your voice or close enough to  
come to your aid when you work near a lead-acid battery.  
2. Have plenty of fresh water and soap nearby in case battery acid  
contacts your skin, clothing, or eyes.  
3. Wear complete eye protection and clothing protection. Avoid  
touching your eyes while working near batteries.  
4. If battery acid contacts your skin or clothing, wash immediately with  
soap and water. If acid enters your eye, immediately flood the eye  
with running cold water for at least ten minutes and get medical  
attention immediately.  
5. Never smoke or allow a spark or flame in the vicinity of the battery or  
engine.  
6. Be extra cautious to reduce the risk of dropping a metal tool onto a  
battery. It might spark or short-circuit the battery or other electrical  
parts that may cause an explosion.

Safety  
7. Remove personal metal items such as rings, bracelets, necklaces, and  
watches when working with a lead-acid battery. A lead-acid battery  
can produce a short-circuit current high enough to weld a ring or the  
like to metal, causing a severe burn.  
8. Never charge a frozen battery.  
9. If it is necessary to remove a battery, always remove the grounded  
terminal from the battery first. Make sure all the accessories are off,  
so as not to cause an arc.  
10. Be sure the area around the battery is well ventilated.  
11. Clean the battery terminals. Be careful to keep corrosion from coming  
in contact with your eyes.  
12. Study all battery manufacturer’s specific precautions such as  
removing or not removing the cell caps while charging and the  
recommended rates of charge.  
13. For refillable (flooded) batteries, add distilled water in each cell until  
the battery acid reaches the level specified by the battery  
manufacturer. This helps to purge excessive gas from cells. Do not  
overfill. Carefully follow the manufacturer’s recharging instructions.

Installation  
AC Components  
AC Input  
AC input to the RS3000 can be supplied from a split-phase or dual-input AC  
source such as the utility grid (power company), a generator, or the output of a  
transfer switch. The RS3000 can be operated from the following types of 120 volt  
60 Hz AC sources:  
Split phase: This source type has two lines, one neutral, and one ground. The  
two 120 VAC lines are 180 degrees out of phase with each other, so that the  
two voltages total to 240 VAC. The voltage between each line and neutral is  
still 120 VAC, and the voltage between the neutral and ground is  
approximately zero.  
Because the two lines are out of phase, the currents from each line subtract in  
the neutral, and the neutral current will be approximately zero if the loads are  
equal. For example, if Line 1 is supplying 20A and Line 2 is supplying 15A,  
the current in the neutral will be 5A.  
Dual input: This source type has two line inputs, one neutral, and one ground.  
Unlike the split-phase type, the two lines are in phase (not out of phase), and  
must come from the same source. The voltage between the two lines is zero.  
The voltage between each line and the neutral is 120 VAC, and the voltage  
between the neutral and ground is approximately zero.  
Because the two lines are in phase, the currents from each line add together in  
the neutral. For example, if Line 1 is supplying 20A and Line 2 is supplying  
15A, the current in the neutral will be 35A.  
Important: Single-phase input (where only one of the AC inputs (L1 or L2) is  
energized) is not supported because the RS3000 is designed for inputs that energize both  
lines (L1 and L2). This may be accomplished with an appropriate transfer switch ahead of  
the RS3000. Consult a qualified installer.  
AC Output  
AC Loads  
AC output from the RS3000 is 120 VAC, and can be wired as single output or dual  
output.  
The RS3000 is intended to power loads consisting of 120 VAC appliances.  
In Invert mode, the RS3000 connects L1 and L2 output lines together to provided  
120 VAC to loads on either line. In AC Bypass mode, the source connected to the  
AC input is passed through to the load. Because of the way invert mode operates,  
only 120 VAC appliances can be connected to the RS3000 output.

Installation  
WARNING: Shock Hazard  
Do not connect 240 VAC loads to the RS3000 outputs. Doing so may result in  
120 VAC on exposed parts of the appliance.  
AC Disconnect and Over-Current Protection Device  
To meet CSA, UL, and electrical code requirements, and to protect system wiring,  
the AC inputs and outputs of the inverter/charger must be provided with over-  
current protection on both the AC input and output. This protection may be a  
circuit breaker or a fuse with a disconnect device (for simplicity the following  
refers to breakers). Refer to your applicable installation codes and the following  
requirements:  
AC Input Protection  
The breakers protecting the AC input of the RS3000 must be approved for use on  
120 VAC branch circuits, and must be located in each Line. The breakers must be  
rated as shown below, so that the 50A maximum current that the inverter/charger  
and its transfer relay can handle is not exceeded:  
Split-phase input: No more than 50 amps max in each line.  
Dual input: The neutral current in a dual-input system is the sum of the two  
line currents, and must be limited to 50A max to protect the transfer relay.  
Each breaker must not exceed 50A, and the total (sum) of the ratings of the  
two breakers must not exceed 50A. For example, if Line 1 has a 30A breaker,  
the Line 2 breaker cannot exceed 20A. The sum of the breakers can exceed  
50A if both are fed from a common feeder line protected at no more than 50A  
(for example a 50A breaker feeding a pair of 30A breakers).  
AC Output Protection  
The breaker between the RS3000 AC output and the AC loads must be rated to  
protect the AC output wire size used. If the AC output wiring is based on the full  
50A pass-through rating, then a 50A output breaker is acceptable. If the AC  
output wiring is smaller, then the breaker size will have to be smaller as well, in  
accordance with applicable electrical installation codes.  
GFCI Requirements  
A GFCI (ground fault circuit interrupter) is a device that deenergizes a circuit  
when a current to ground exceeds a specified value that is less than that required  
to open the circuit breaker. GFCIs are intended to protect people from electric  
shocks and are usually required in wet or damp locations.  
Installation in recreational vehicles requires GFCI protection of certain branch  
circuits. Consult all applicable codes.

Installation  
Tested GFCIs  
Compliance with UL standards requires that Xantrex test and recommend specific  
GFCIs for use on the output of the inverter. Table 1 lists models that have been  
tested and will function properly when connected to the AC output of the RS3000.

Disconnect Devices  
Each system requires a method of disconnecting the AC circuits. If the over-  
current protection device is a circuit breaker, it will also serve as the disconnect. If  
fuses are used, separate AC disconnect switches will be needed between the  
source and the fuses.  
Distribution Panels  
Some systems incorporate distribution panels both ahead of the inverter/charger  
(the AC source panel) and between the inverter/charger and the loads (the AC  
load panel). The AC source panel includes a main circuit breaker, which serves as  
over-current protection for the panel. Additional circuit breakers serve individual  
circuits, one of which serves the inverter/charger.  
AC Wiring  
Definition  
AC wiring includes input wiring (all the wires and connectors between the AC  
source and the inverter/charger input) and output wiring (all the wires between the  
inverter/charger and the AC load panels, circuit breakers, and loads).  
Type  
The type of wiring required varies according to the electrical codes or regulations  
applicable to your installation. For RV applications, this may be solid wire in  
multi-conductor cables, but stranded wire is required if single conductors are  
used. All wiring must be rated 90 °C or higher.

Installation  
Size of Input Wiring  
Wire size must be coordinated with the overcurrent protection provided ahead of  
the wire involved, in accordance with the electrical codes or regulations  
applicable to your installation.  
Therefore, the wiring used between the AC input circuit breaker and the inverter/  
charger input must be sized to match the input breaker rating.

Size of Output  
Wiring  
Wire size must be coordinated with the current the wiring will carry. This may be  
determined by the 25 A maximum inverter current, or by the bypass current,  
which is determined by the overcurrent protection provided ahead of the RS3000  
If the input wiring is split-phase, the output wiring must be sized to coordinate  
with the breakers used on the input. Refer to your applicable installation  
codes. For a 50 A input breaker, the output wiring is usually No. 8 AWG.  
If the input wiring is dual-input and the output wiring is single-input, the  
following rules apply: If the input breaker on L1 is greater than 25 A, the wire  
size must be coordinated for that amperage. If the input breaker on L1 is less  
than 25 A, the wire size must be coordinated for 25 A. The wire size must not  
be sized for anything lower than 25 A.  
If both the input and the output wiring are dual-input, the output wiring for  
each line (L1 and L2) must be calculated separately, following these rules: If  
the input breaker on the specific line is greater than 25 A, the wire size for that  
line and its neutral must be coordinated for that amperage. If the input breaker  
on the specific line is less than 25 A, the wire size for that line and its neutral  
must be coordinated for 25 A. The wire size must not be sized for anything  
lower than 25 A.  
Size of Wiring  
Downstream of the  
AC Output Breaker  
The wiring used between the AC output breaker and your loads must be sized to

Installation  
AC Output Neutral Bonding  
The AC source must have its neutral conductor bonded to ground.  
Bonding system  
The RS3000 provides a system that automatically connects the neutral conductor  
of the inverter’s AC output circuit to safety ground (“bonding” it) while the  
inverter/charger is inverting, and disconnects it (“unbonding” it) when the  
inverter/charger is connected to external AC power. This system is designed to  
conform to installation codes that require AC sources such as inverters and  
generators to have their neutral conductors tied to ground at the source of power in  
the same way that the neutral conductor from the utility is tied to ground. These  
same codes specify that the neutral can only be connected to ground in one place  
at any one time.  
Suitability  
This automatic neutral-to-ground bonding system requires AC input sources with  
bonded neutral. This will be the case in most situations: in a utility feed, at an  
external AC hook-up, or a generator with a bonded neutral. If not, have an  
electrician look into bonding the source’s neutral to ground. See also “AC Input

Restrictions on the size of appliances.  
For information on cabling and hooking up batteries, see “Cabling and Hook-up  
For detailed information about specific brands of batteries, you’ll need to consult  
individual battery manufacturers for this information.  
DC Disconnects and Over-Current Devices  
The DC circuit from the battery to the inverter/charger must be equipped with a  
disconnect and over-current protection device. (Refer to your applicable  
installation code.)  
Type  
This device usually consists of a circuit breaker, a “fused-disconnect,” or a  
separate fuse and DC disconnect. Do not confuse AC circuit breakers with DC  
circuit breakers. They are not interchangeable.  
Rating  
The rating of the fuse or breaker must be matched to the size of cables used in  
accordance with the applicable installation codes.  
Location  
The breaker or fuse and disconnect should be located as close as possible to the  
battery in the positive cable. Applicable codes may limit how far the protection  
can be from the battery.

Installation  
Installing the Inverter/Charger  
Overview  
This section provides detailed information on installing the RS3000. The overall  
procedure is divided into eight steps:  
Step 1: Choosing a Location for the Inverter/Charger  
WARNING: Risk of fire or explosion  
This equipment contains components that could produce arcs or sparks. To reduce the risk  
of fire or explosion, do not install this equipment in compartments containing batteries or  
flammable materials, or in locations that require ignition-protected equipment. This  
includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings,  
or other connections between components of the fuel system.  
WARNING: Fire hazard  
Do not cover or obstruct the ventilation openings. Do not install this equipment in a  
compartment with limited airflow. Overheating may result.  
The location of the inverter/charger is a key factor in system performance.  
Allow sufficient clearance around the unit (recommended minimum 3 inches  
(76 mm)) and install in a well-ventilated compartment to prevent overheating and  
premature shutdown of the inverter/charger.  
The inverter should only be installed in a location that meets the following  
requirements:  
Ventilated  
Do not operate the inverter/charger in a closed-in area or restrict  
ventilation in any way. The inverter/charger requires air circulation  
to maintain optimum operating temperature and provide best  
performance. If the unit has inadequate ventilation, it may shut down  
due to overheating.  
The air vented through the openings should also have a path to  
circulate away from the inverter/charger.

Installation  
Dry  
Do not allow water or other fluids to drip or splash on the inverter.  
Do not expose to rain, snow or water.  
Cool  
Normal air temperature should be between 32 °F and 122 °F  
(0 °C and 50 °C)—the cooler the better within this range.  
Clearance  
Allow as much space around the inverter/charger as possible.  
Xantrex recommends that other objects and surfaces be at least  
3 inches (76 mm) away from the ventilation openings for best  
performance.  
Safe  
Locate the inverter/charger away from battery in a separate well  
ventilated compartment. Do not install the inverter/charger in any  
compartment containing flammable gases or liquids like gasoline.  
Close to  
battery  
compartment  
The length and size of your DC cables will affect performance. Use  
the DC cables recommended in Table 3 on page 14. The unit should  
not be installed in the battery compartment due to the possible  
presence of explosive hydrogen gas from the batteries.  
Protected  
from battery  
Never place the inverter/charger directly above the batteries—gases  
from battery will corrode and damage the inverter/charger. If the  
acid and gases inverter/charger is installed in a compartment above the batteries,  
make sure there is a solid, gas-impermeable wall dividing the two  
compartments.  
Never allow battery acid to drip on the inverter/charger or its wiring  
when filling the batteries or reading their specific gravity.  
Orientation  
To meet regulatory requirements, the RS3000 must be mounted in  
one of the approved mounting orientation. See Figure 4 on page 20.  
WARNING: Fire Hazard  
Mount the RS3000 only in an approved orientation.

Step 2: Mounting the Inverter/Charger  
Considerations  
Before mounting the RS3000, take the following two factors into account.  
1. The weight of the inverter/charger requires two people to install it.  
2. Mounting considerations are shown in Figure 4 on page 20.  
WARNING: Heavy load  
The RS3000 Sine Wave Inverter/Charger is heavy (see “Inverter/Charger Physical  
Specifications” on page 38). The unit is too heavy for one person to safely lift and mount.  
Xantrex recommends that two people lift and mount the unit. Always use proper lifting  
techniques during installation to prevent personal injury.

Installation  
Step 3: Connecting the AC Input and AC Output Wires  
WARNING: Fire, shock, and energy hazards  
Make sure wiring being connected to the inverter/charger is disconnected (physically or  
by opening the breaker) from all electrical sources before handling. All wiring must be  
done in accordance with local and national electrical wiring codes.  
General AC Wiring Considerations  
AC and DC Wiring Separation Do not mix AC and DC wiring in the same  
conduit or panel. Consult the applicable installation code for details about DC  
wiring and AC wiring in vicinity to each other.  
AC Input and Output Isolation The AC input and output circuits of this  
inverter/charger are isolated from each other when in invert mode to ensure safe  
operation. This isolation must be maintained in the installation, by being sure not  
to connect AC input and output wiring to a common point. For example, do not  
route the AC input and output neutrals to a common neutral bus.  
AC Wiring Compartment For your reference, the AC wiring compartment is  
shown in Figure 5 on page 22.  
AC Knockouts There are two 3/4" trade-size knockouts on the front panel for  
AC wiring. For easier wiring access, there are also 1" trade-size knockouts on  
either side of the unit (not shown). Use the same trade size of strain relief as the  
trade size of the knockout(s) you are using.  
AC Wiring Terminals The AC wiring terminals accept cables of a specific

Step 4: Connecting the DC Cables  
DC Connection Precautions  
WARNING: Energy hazard  
Connect and disconnect DC wiring only after opening the disconnect switches or breakers  
at all AC and DC sources.  
Recommended Cable Sizes and Lengths and Fuse Size  
For recommended DC cables and fuse size, see Table 3 on page 14.  
Preparing the Cables  
To prepare the DC cables:  
1. Cut the negative and positive cables to the required length. Strip off enough  
insulation so you can install the terminals you will be using.  
Xantrex recommends the use of crimp connectors. The connector should be  
designed for a 3/8" stud size to connect to the RS3000. If a crimp connector is  
used, it should be crimped using the tool indicated by the connector  
manufacturer.  
2. Cut the DC ground cable to the required length. Strip off enough insulation so  
you can install the terminals you will be using.  
Xantrex recommends the use of crimp connectors. The connector should be  
designed for a 1/4" stud size to connect to the RS3000. If a crimp connector is  
used, it should be crimped using the tool indicated by the connector  
manufacturer.  
3. Attach the connectors to the ends of both cables. Make sure no stray wire  
strands protrude from the connectors.

Installation  
Guidelines for Routing the DC Cables  
Follow these guidelines to ensure maximum performance.  
WARNING: Fire and shock hazard  
Route the cables away from sharp edges that might damage the insulation. Avoid sharp  
bends in the cable.  
Do not attempt to use the chassis in place of the battery negative connection  
for grounding. The inverter requires a reliable return path directly to the  
battery.  
To reduce the chance of radio frequency interference, keep the positive and  
negative cables close together—ideally, held together by straps, loom, or  
insulated clamps at regular intervals.  
To ensure maximum performance from the inverter/charger, do not route your  
DC cables through a DC distribution panel, battery isolator, or other device  
that will cause additional voltage drops. The exception is the DC fuse and  
Disconnect or the DC circuit breaker which is required at the battery to  
protect the DC wiring.  
To help avoid damage caused by reverse polarity battery connection, it is a  
good idea to mark each end of each cable to identify it as a positive (red) or  
negative (black) cable before routing the wiring.

Installation  
Connecting the DC Cables to the Inverter/Charger  
WARNING: Fire hazard  
Use only appropriately sized copper cable. Loose connections or improper connections  
will overheat. Make sure the bolts supplied by Xantrex on the inverter/charger are  
tightened to a torque of 15–16 ft-lbs (20.4–21.7 Nm). Torque all other connections to the  
manufacturer’s specifications. Make sure the DC cable, washers, and bolt are assembled  
in the order shown in Figure 6.  
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 (–).  
To connect the DC cables:  
1. Route the DC cables from the battery bank to the inverter/charger. Observe  
2. Install a DC fuse and disconnect switch or a DC circuit breaker between the  
inverter/charger and the battery. It must be installed in the positive side of the  
DC circuit, as close as possible to the battery.  
This protects your battery and wiring in case of accidental shorting. See  
Table 3 on page 14 for required fuse or breaker size.  
3. Open the DC disconnect switch or turn off the DC circuit breaker.  
4. Connect one connector on the POSITIVE (+) cable to the POSITIVE DC  
terminal on the inverter/charger, as shown in Figure 6. The connector goes on  
first, then the flat washer (steel), lock washer (steel), and 3/8" bolt (brass).  
5. Connect the other connector to the POSITIVE (+) terminal on the fuse or  
breaker. Observe polarity carefully while completing the installation.  
Use a wrench to tighten the bolt to a torque of 15–16 ft-lbs (20.4–21.7 Nm) at  
the inverter/charger end. Observe the fuseholder or breaker manufacturer’s  
recommendation at the other end.  
6. Connect one connector on the NEGATIVE (–) cable to the NEGATIVE (–)  
DC terminal on the inverter/charger, as shown in Figure 6. The connector  
goes on first, then the flat washer (steel), lock washer (steel), and 3/8" bolt  
(brass).

Installation  
DC Grounding  
The Chassis Ground point on the inverter/charger is used to connect the chassis of  
the inverter/charger to your system’s DC grounding point, as required by  
regulations for some installations. Use copper wire that is either bare or provided  
with green insulation.  
The grounding guideline given below assumes you are using the code-compliant  
DC supply cable and fuse sizes indicated on page 14. If you are using different  
sizes, refer to the applicable code for DC grounding detail.  
To connect the chassis ground:  
1. Using the appropriate wrench, loosen the bolt on the chassis ground point  
shown in Figure 8.  
2. Connect the grounding cable (see page 25) between the chassis ground point  
and the DC grounding point for your system.  
In an RV or vehicle installation, the DC grounding point will usually be the  
vehicle chassis or a dedicated chassis ground bus.  
3. Tighten the screw to a torque of 1.0–1.25 ft-lbs (1.47–1.7 Nm).

Installation  
Step 5: Connecting the Battery Temperature Sensor (BTS)  
Installing a battery temperature sensor (BTS) extends the life of a battery by  
preventing overcharging in warm temperatures and undercharging in cold  
temperatures. With a BTS monitoring the battery temperature, the voltage  
delivered to the battery is adjusted according to the battery’s actual temperature.  
The BTS has a self-adhesive backing and attaches to the side of the battery. A  
25-foot (7.6 m) cable is supplied with the BTS, as shown in Figure 9.  
Figure 9 BTS with Cable  
WARNING: Energy and explosion hazard  
Review the “Important Safety Instructions” on page v.  
Mounting Options  
You can mount the BTS in one of two ways:  
Mounting the sensor to the negative battery post allows the internal battery  
temperature to be sensed and provides the most accurate results.  
Attaching the sensor to the side of the battery using the self-adhesive backing  
also provides good results in most situations.

Installation  
Mounting to the Negative Battery Terminal  
To mount the sensor on the negative battery terminal:  
Figure 10 BTS Mounted on the Negative Battery Terminal  
1. Select the battery to be monitored. The BTS should be connected to the  
battery bank that is directly connected to the inverter/charger.  
2. Switch off all devices operating from the battery, or open the battery switch (if  
present) to disconnect the battery.  
3. Wait 10 minutes for any explosive battery gases to dissipate.  
4. Remove the nut that connects existing wiring ring terminals to the battery  
negative terminal stud.  
5. Move or reorient the existing wiring ring terminals on the battery negative  
terminal stud, so there is a flat surface on which to seat the BTS mounting  
plate.  
You may need to bend the ring terminal crimp and/or wires slightly downward  
to allow the sensor to seat flush to the top surface of the upper ring terminal.  
6. Mount the sensor directly on top of the ring terminal, as shown in Figure 10,  
and firmly tighten the terminal nut.  
WARNING: Fire hazard  
In this procedure, you must install the DC wire on the battery terminal, then install the  
sensor on top of the DC wire. This sequence is required to provide the best connection to  
the battery and to ensure correct performance of the sensor.  
7. Check to ensure that the sensor and all wires are held firmly and cannot be  
moved.

Battery Information  
Battery Bank Sizing  
Battery capacity  
Battery size or capacity is just as important as the battery type selected for use  
with the RS3000. The batteries are the most important part of your system, so  
Xantrex recommends that you purchase as much battery capacity as possible. A  
large battery will extend running time and ensure that your inverter/charger  
delivers full rated surge.  
Xantrex recommends a minimum battery size of 200 amp-hours (Ah) for  
moderate loads (<1000W) and greater than 400 Ah for heavy loads.  
See “Estimating Battery Requirements” below for information on a more detailed  
calculation.  
About Amp-hours  
A number of different standards are used to rate battery energy storage capacity.  
Automotive and marine starting batteries are normally rated in cranking amps.  
This is not a relevant rating for continuous loads like an inverter. Deep-cycle  
batteries use a more suitable rating system such as amp-hours (Ah).  
Amp-hour capacity is the number of amps a battery can continuously deliver  
during a specified number of hours. It is represented by the product of the two —  
amps multipled by hours.  
A typical marine or RV battery rated for 100 Ah can deliver 5 amps for 20 hours  
(5A × 20 hours = 100 Ah). This same battery can deliver a higher or lower current  
for less or more time, limited approximately by the 100 Ah figure (50 A for 2  
hours or 200 A for 1/2 hour), but usually the capacity figure given is only accurate  
for the specified duration (20 hours).  
Estimating Battery Requirements  
Calculating Battery Size  
Step1: Compute  
Amp-hours  
For each appliance, compute the number of amp-hours that will be used between  
charging cycles, as follows:  
1. Obtain the wattage. If the wattage is marked on the nameplate rating, use that.  
Otherwise, multiply the marked voltage and amperage:  
WATTS = VOLTS × AMPS.  
2. Obtain the Watt-hours by multiplying that amount by the hours the appliance  
will be used:  
WATT-HOURS = WATTS × HOURS.  
3. Obtain the amp-hours that the appliance requires by dividing that amount by  
10 (the factor for the RS3000, which is a 12-volt system):  
BATTERY AMP-HOURS USED = AC WATT-HOURS/10  
For example, a 100 W light bulb that is used for 4 hours will use 400 watt-hours  
(Wh) and the inverter will consume approximately 40 Ah from a 12 volt battery.

Installation  
4. Enter this information on the blank calculation worksheet (page 42).  
Step 2: Calculate  
Battery Size  
5. Complete the rest of the worksheet; see Table 1-1, “Battery Sizing Example”  
on page 41 for an example.  
Size the batteries at approximately twice the estimated total amp-hour usage.  
Doubling the expected amp-hour usage ensures that the batteries will not be  
overly discharged and extends battery life.  
Resist the temptation to skip this doubling step. More capacity is better since you  
will have more reserve capacity, be better able to handle large loads and surge  
loads, and your battery won’t be discharged as deeply. Battery life is directly  
dependent on how deeply the battery is discharged. The deeper the discharge, the  
shorter the battery life.  
Troubleshooting  
If you find that the system shuts down when appliances with large motors are  
started, the problem may be that this motor is too much for the battery. Even  
though you calculated the amp-hour requirements appropriately, the startup of a  
large motor makes high demands on the battery. You may find that adding more  
amp-hours (in the form of extra batteries or replacement with a bigger battery)  
solves the problem.

This example illustrates how quickly your battery needs can escalate. To reduce  
the required battery bank size, you can either conserve energy by eliminating or  
reducing the use of some loads, or recharge more frequently.

Installation  
Battery Banks  
As your power requirements increase, you may need to use more than one battery  
to obtain sufficient capacity. Batteries can be connected in parallel, in series, or in  
series-parallel to create higher capacity systems.  
about battery inter-connection schemes.  
Mixing Batteries  
Batteries connected in parallel should be of the same type and amp-hour rating  
and from the same manufacturer.  
It is not recommended to connect batteries of different types, amp-hour ratings or  
manufacturers. Improper charging and decreased battery life will result.  
Battery Bank Sizing Worksheet  
The following worksheet is a guide to help you determine your battery needs. Be  
generous in estimating the time for which you will run each of the loads to ensure  
sufficient battery capacity.  
Restrictions on Motor Size  
An appliance may require three to six times its normal running current in order to  
start. The RS3000 can handle surges to 7500 VA for 5 seconds, which translates to  
a locked rotor amp on the motor of no more than 60 A. The locked rotor amp may  
be specified on the motor nameplate as “LRA” or “LRI”.  
When considering appliances with large motors, follow these guidelines:  
Make sure that the motor’s LRA rating is no more than 60 A. The RS3000  
may not be able to start a motor with a higher LRA, and the RS3000 will shut  
down if the attempt is made.  
Make sure the battery bank, DC cables and DC fuses are capable of handling  
up to 750 A DC for five seconds. A weaker circuit may not be able to provide  
sufficient power to the RS3000 to allow the RS3000 to start up the appliance.  
Again if the circuit cannot deliver the required current, the system may shut  
down or the fuse may open.

Cabling and Hook-up Configurations  
Several smaller batteries can be connected to create a battery bank of substantial  
size. You can connect batteries in three ways: in parallel, series, or series-parallel.  
To make a larger battery bank, connect individual batteries with heavy cables. The  
actual size of the cable depends on whether the batteries are connected in parallel  
or series. Generally, the cable should not be smaller than the inverter cables—if  
the main cables are 4/0 AWG, the battery interconnects should be 4/0 AWG.  
The best configuration is to connect the batteries in series and parallel. This  
requires additional cables, but reduces imbalances in the battery bank and can  
improve the overall performance. Consult your battery supplier for more  
information regarding the hook-up configuration required for your system.  
Parallel Connection  
Batteries are connected in parallel when all the positive terminals of a group of  
batteries are connected and then, separately, all the negative terminals are  
connected. In a parallel configuration, the battery bank has the same voltage as a  
single battery, but an Ah rating equal to the sum of the individual batteries. See  
Figure 16 Batteries Connected in Parallel

Installation  
Series Connection  
When batteries are connected with the positive terminal of one battery to the  
negative terminal of the next battery, they are connected in series. In a series  
configuration, the battery bank has the same Ah rating of a single battery, but an  
overall voltage equal to the sum of the individual batteries. See Figure 17.

Installation  
Series-Parallel Connections  
As the name series-parallel implies, both the series and parallel configurations are  
used in combination. The result is an increase in both the voltage and the capacity  
of the total battery bank. This is common with all battery-inverter system  
voltages. The smaller, lower voltage batteries are first connected in series to  
obtain the necessary voltage, and then these “batteries connected in series” sets  
are connected in parallel to increase the battery bank capacity. See Figure 18.
