1800.  
WARNING: Limitations on use  
The Freedom HF is not intended for use in connection with life support systems  
or other medical equipment or devices.  
1. BEFORE INSTALLING AND USING THE FREEDOM HF, READ ALL  
INSTRUCTIONS AND CAUTIONARY MARKINGS ON THE FREEDOM HF,  
THE BATTERIES, AND ALL APPROPRIATE SECTIONS OF THIS GUIDE.  
CAUTION: Risk of injury  
To reduce the risk of injury, charge only 12 Vdc lead-acid (GEL, AGM, or  
Flooded) rechargeable batteries. Other battery types may burst, causing personal  
injury and damage.  
2. Do not expose the Freedom HF to rain, snow, spray, or bilge water.  
To reduce risk of fire hazard, do not cover or obstruct the ventilation  
openings. Do not install the Freedom HF in a zero-clearance  
compartment. Overheating may result.  
3. 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 Freedom HF with damaged or substandard wiring.  
4. The use of any attachments not recommended or sold by Xantrex,  
may result in risk of fire, electric shock, or injury to persons.  
5. Do not operate the Freedom HF if it has received a sharp blow, been  
dropped, or otherwise damaged in any way. If the Freedom HF is  
damaged, see the Warranty section.  
v
Safety  
6. Do not disassemble the Freedom HF. It contains no user-serviceable  
parts. See Warranty for instructions on obtaining service. Attempting  
to service the Freedom HF yourself may result in a risk of electrical  
shock or fire and will void your warranty. Internal capacitors remain  
charged after all power is disconnected.  
7. To reduce the risk of electrical shock, disconnect both AC and DC  
power from the Freedom HF before attempting any maintenance or  
cleaning or working on any circuits connected to the Freedom HF.  
Turning off controls will not reduce this risk.  
8. The Freedom HF must be provided with an equipment-grounding  
conductor connected to the AC input ground.  
WARNING: Explosion hazard  
1. WORKING IN THE VICINITY OF BATTERIES IS DANGEROUS. BATTERIES  
GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION.  
THEREFORE, IT IS OF UTMOST IMPORTANCE THAT EACH TIME BEFORE  
SERVICING THE UNIT IN THE VICINITY OF THE BATTERY, THAT YOU  
READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY.  
2. This equipment contains components which tend to produce arcs or  
sparks. To prevent fire or explosion, do not install the Freedom HF 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, as well as  
joints, fittings, or other connections between components of the fuel  
system.  
3. To reduce the risk of battery explosion, follow these instructions and  
those published by the battery manufacturer and the manufacturer of  
any unit you intend to use in the vicinity of the battery.

Safety  
Personal Precautions When Working With Batteries  
WARNING: BATTERIES PRESENT RISK OF ELECTRICAL SHOCK  
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE OR  
EXPLOSION FROM ENTED GASES. OBSERVE PROPER  
PRECAUTIONS  
,
V
.
1. Study and follow all of the battery manufacturer's specific  
precautions, such as removing or not removing cell caps while  
charging, and recommended rates of charge.  
2. Add distilled water in each cell until battery acid reaches the level  
specified by the battery manufacturer. This helps to purge excessive  
gas from cells. Do not overfill. For a battery without cell caps,  
carefully follow manufacturer's recharging instructions.  
3. Make sure the area around the battery is well ventilated.  
4. Never smoke or allow a spark or flame near the engine or batteries.  
5. Use extra caution to reduce the risk or dropping a metal tool on the  
battery. It could spark or short circuit the battery or other electrical  
parts and could cause an explosion.  
6. Remove all metal items, like rings, bracelets, and watches when  
working with batteries. Batteries can produce a short circuit current  
high enough to weld metal to skin, causing a severe burn.  
7. Have someone within range of your voice or close enough to come to  
your aid when you work near a lead-acid battery.  
8. Have plenty of fresh water and soap nearby in case battery acid  
contacts skin, clothing, or eyes.  
9. Wear complete eye protection and clothing protection. Avoid  
touching your eyes while working near batteries.  
975-0390-01-01  
vii  
Safety  
10. If battery acid contacts skin or clothing, wash immediately with soap  
and water. If acid enters your eye, immediately flood it with running  
cold water for at least twenty minutes and get medical attention  
immediately.  
11. If you need to remove a battery, always remove the ground terminal  
from the battery first. Make sure all accessories are off so you don’t  
cause an arc.  
12. Never charge a frozen battery.  
13. Clean battery terminals. Be careful to keep corrosion from coming  
into contact with your eyes.  
MARINE UNIT LOCATION  
14. Locate the Freedom HF unit away from batteries in a separate, well  
ventilated compartment.  
15. Never place the Freedom HF unit directly above batteries; gases from  
a battery will corrode and damage the unit  
16. Never allow battery acid to drip on the unit when reading gravity, or  
filling battery.  
17. Do not operate the unit in a closed in area, or restrict the ventilation in  
any way.  
DC CONNECTION PRECAUTION  
18. Connect and disconnect DC output connections only after setting any  
marine unit switches to off position and opening AC disconnect  
19. FOR MARINE INSTALLATIONS, EXTERNAL CONNECTIONS  
TO THE UNIT SHALL COMPLY WITH THE UNITED STATES  
COAST GUARD ELECTRICAL REGULATIONS(33CFR183, SUB  
PART I)  
20. PROPER DISPOSAL OF BATTERIES IS REQUIRED. REFER TO  
YOUR LOCAL CODES FOR DISPOSAL REQUIREMENTS.

Safety  
Precautions for Using Rechargeable Appliances  
CAUTION: Equipment damage  
Most rechargeable battery-operated equipment uses a separate charger or  
transformer that is plugged into an AC receptacle and produces a low  
voltage charging output.  
Some chargers for small rechargeable batteries can be damaged if  
connected to the Freedom HF. Do not use the following with the Freedom  
HF:  
•
Small battery-operated appliances like flashlights, razors, and night  
lights that can be plugged directly into an AC receptacle to recharge.  
•
Some chargers for battery packs used in power hand tools. These  
affected chargers display a warning label stating that dangerous  
voltages are present at the battery terminals.  
Important: if you are unsure about using your rechargeable appliance with the  
Freedom HF, contact the equipment manufacturer to find out if the appliance is  
acceptable for use with modified sine wave input voltage. See the detailed  
description of the Freedom HF waveform in Appendix A, “Specifications” under  
“Electrical Specifications: Inverter Mode” on page A–2.

Introduction  
Chapter 1 introduces you to the Freedom HF, explains  
the inverting, charging, and power system management  
functions.  
It covers the following:  
•
•
Freedom HF’s major features, and  
Freedom HF’s function as an independent power  
system.  
1–1  
Freedom HF Inverter/Charger  
Congratulations on your purchase of the Freedom HF Inverter/Charger  
(Freedom HF). As part of the Freedom Inverter/Charger family, the  
Freedom HF 1000 and Freedom HF 1800 give you quality power, worry-  
free operation, and outstanding reliability. The Freedom HF’s integrated  
inverting–charging functions and numerous power management features  
make it ideal for marine installations, recreational and commercial  
vehicles.  
Quality Power  
The Freedom HF provides up to 1000 watts (Freedom HF 1000) or up to  
1800 watts (Freedom HF 1800) of continuous modified sine wave power  
from a battery bank. It is designed to handle loads such as a 600-watt  
microwave (Freedom HF 1000) or 1000-watt microwave (Freedom HF  
1800), TVs, VCRs, and midsized power tools.  
The Freedom HF’s high surge capability lets you handle many hard-to-  
start loads, including large TVs and small refrigerators.  
The built-in transfer switch automatically transfers between inverter  
power and incoming AC power (shore power) to ensure power is always  
available.  
The built-in charger automatically charges the battery bank when the  
Freedom HF is connected to incoming AC power (shore power).  
Comprehensive  
Protection  
The Freedom HF’s built-in protection features safeguard your batteries  
and equipment to give you worry-free operation:  
•
•
•
The low battery voltage alarm and shutdown prevents your  
batteries from becoming completely discharged.  
The three-stage charging capability ensures that batteries receive  
the “best” charge with minimal wear and tear.  
If the Freedom HF detects “bad” AC voltage, it switches  
automatically to Inverter mode and supplies your equipment with  
modified sine wave power derived from the batteries. When “good”  
AC becomes available again, the Freedom HF allows the AC to pass  
through to your loads and automatically begins to recharge the  
batteries.  
Reliable  
Back-up  
If incoming shore power fails, the Freedom HF automatically detects the  
failure and instantly becomes an independent power source that supplies  
quality AC to your loads.  
1–2  
975-0390-01-01  
Independent Power System  
Overload  
Alarm and  
Shutdown  
During Inverter mode, the Freedom HF automatically alerts you if the  
loads that are connected and drawing power from the unit are close to the  
maximum operating limit.  
The Freedom HF automatically shuts down when the maximum operating  
limit is exceeded.  
Over-temp  
Alarm and  
Shutdown  
During Inverter mode, the Freedom HF automatically alerts you if it is  
overheating and approaching the over-temperature shutdown limit.  
The Freedom HF automatically shuts down when the limit is exceeded.  
Independent Power System  
Your Freedom HF has been designed to be the heart of a sophisticated,  
independent power system. While the Freedom HF is an extremely  
“friendly” product to operate, Xantrex wants to ensure that you get the  
best performance from your system.  
Inverting  
Charging  
Freedom HF produces 120 Vac from your 12V batteries and is capable of  
starting heavy loads like refrigerators and pumps.  
When the Freedom HF is inverting (producing 120 Vac output) without a  
load, it draws less than 1A of current from the battery (or battery bank).  
This feature allows the unit to operate without draining too much stored  
energy.  
For the inverter to perform effectively, the batteries must be charged  
correctly. The unit has a built-in three-stage charging system that extends  
the life and optimizes the performance of the batteries.  
In addition to the numerous features which let you maximize your  
battery’s life and performance, the Freedom HF—unlike many  
chargers—also has the ability to recharge batteries even if the voltage is  
near zero (sometimes called dead battery charging).

Operating in Shore Power Mode  
Operating in Shore Power Mode  
The Freedom HF operates in shore power mode when an AC source (a  
generator or utility power) is present at the AC input terminals. When the  
AC source is within operating range, the Freedom HF unit bypasses  
inverter function and powers the appliances connected to the unit. See  
“Transitioning from Inverter Mode to Shore Power” on page 4–7.  
The Freedom HF also automatically charges the battery bank that is  
connected while in shore power mode. See “Battery Charging” on  
page 4–11.  
The Green status LED lights up to indicate that the Freedom HF is using  
utility (or generator) power and the battery is full. A flashing Green LED  
indicates that the unit is charging the battery.  
When shore power is present, AC power will automatically pass through  
the Freedom HF. Pressing the Inverter button on the display panel will not  
interrupt the supply of shore power. Shore Power mode supersedes  
Inverter mode.  
When the Freedom HF ‘s Inverter button is turned ON and the AC source  
is outside the operating range or is disconnected, the transfer switch  
automatically switches to inverter mode. See “Transitioning from Shore  
Power to Inverter Mode” on page 4–7.  
975-0390-01-01

Operating in Inverter Mode  
The Freedom HF is in inverter mode when shore power is not presently  
available and the unit is using the battery (inverting DC to AC) to power  
the appliances connected to the Freedom HF.  
The Yellow status LED lights up to indicate the Freedom HF is using the  
battery to power the appliances.  
The table below illustrates the battery status during inverter mode as  
shown on the display panel.  
Turning the Inverter Function On and Off  
The Inverter button on the display panel turns the Freedom HF’s Inverter  
function ON and OFF. To operate, press the button and hold for one  
second.  
When shore power is NOT present:  
•
the AC outlets will supply power to any attached appliances when the  
Inverter button is turned ON, and  
•
the AC outlets will not supply power to any attached appliances when  
the Inverter button is turned OFF.  
WARNING: Shock hazard  
Turning the Inverter button OFF does not disconnect DC battery power from the  
Freedom HF. You must disconnect both AC and DC power before working on  
any circuits connected to the Freedom HF.  
To prevent unnecessary battery discharge, turn the Inverter button off  
when you are not using the Freedom HF.

Checking Output Power  
During Inverter mode, you can check how much power (displayed in kW)  
the Freedom HF is supplying to the connected loads by pressing the  
Select button until the Output Power LED illuminates.  
Operating Several Loads at Once  
If you are going to operate several loads from the Freedom HF, turn them  
on one at a time after you have turned the inverter on.  
Turning loads on separately helps to ensure that the inverter does not have  
to deliver the starting current for all the loads at once, and will help  
prevent an overload shutdown.  
Turning the Audible Alarm ON or OFF  
The Freedom HF’s audible alarm can be turned ON or OFF. Any  
warnings such as fault conditions or imminent shutdown are both  
displayed on the display panel’s screen and sounded on the alarm  
speakers.  
It is not possible to turn OFF the screen and prevent it from displaying  
error codes but it is possible to turn OFF the audible alarm.  
Note: The alarm setting will reset to its default setting when the  
Freedom HF’s Inverter button is turned OFF then turned ON  
again.

975-0390-01-01  
Operating During Transition Between Shore Power and Inverter Mode  
Operating During Transition Between Shore Power and  
Inverter Mode  
The Freedom HF’s advanced power management is capable of  
transitioning power from an AC source to DC source within a fraction of  
a second and vice-versa.  
The Freedom HF automatically detects when shore power is present and  
when it becomes unavailable or drops to less than 90 Vac.  
Transitioning from Shore Power to Inverter Mode  
When the unit is operating in shore power mode and shore power is lost,  
the Freedom HF has less than 30 ms (milliseconds) to switch to inverter  
mode and start drawing power from the battery.  
The Status LED will turn from solid or flashing GREEN to a solid  
YELLOW.  
Transitioning from Inverter Mode to Shore Power  
When the unit is operating in inverter mode and shore power becomes  
available, the Freedom HF begins a 20-second countdown to verify the  
stability of the shore power. If shore power remains stable within 20  
seconds, at the end of the countdown, the Freedom HF has less than 30 ms  
(milliseconds) to switch to shore power mode and start drawing power  
from the AC source.  
The Status LED will turn from solid YELLOW to flashing YELLOW  
during the 20-second countdown, then turn to GREEN when battery  
power is transitioned successfully to shore power.

975-0390-01-01  
Inverter Loads  
Inverter Loads  
The Freedom HF will operate most AC loads within its power rating of  
1000 watts (Freedom HF 1000) or 1800 watts (Freedom HF 1800).  
However, some appliances and equipment may be difficult to operate, and  
other appliances may actually be damaged if you try to operate them with  
the Freedom HF. Please read “High Surge Loads” and “Trouble Loads”  
carefully.  
Overload Conditions  
There are two kinds of overload conditions:  
•
•
An overload warning and  
An overload shutdown.  
Overload  
Warning  
When the Freedom HF’s AC load is approximately 100 W below the  
overload shutdown limit of ~1000 W (Freedom HF 1000) and ~1800 W  
(Freedom HF 1800), the audible alarm beeps once every two seconds and  
the display screen shows a fault code E06.  
Overload  
Shutdown  
When the Freedom HF’s AC load increases to near ~1100 W (Freedom  
HF 1000) and ~2000 W (Freedom HF 1800), the audible alarm beeps  
every second and the display screen shows a fault code E03. The Status  
LED turns solid RED and in 30 seconds, both the unit and the display  
screen will shut down to prevent damage to the inverter and protect the  
battery from being over-discharged.  
High Surge Loads  
Some induction motors used in freezers, pumps, and other motor-operated  
equipment require high surge currents to start. The Freedom HF may not  
be able to start some of these motors even though their rated steady state  
current draw is within the inverter’s limits. The unit will shut down and  
indicate an overload shutdown.  
975-0390-01-01  
4–9  
Trouble Loads  
CAUTION  
Some equipment may be damaged by the Freedom HF’s modified sine wave  
output, which has a different wave form than utility-supplied electricity.  
Some appliances, including the types listed below, may be damaged if  
they are connected to the Freedom HF:  
•
Speed controllers found in some fans, power tools, kitchen  
appliances, and other loads may be damaged.  
•
Some chargers for small rechargeable batteries can be damaged. See  
“Precautions for Using Rechargeable Appliances” on page ix for  
details.  
•
Metal halide arc (HMI) lights can be damaged.  
Important: If you are unsure about operating any device with the Freedom  
HF, contact the manufacturer of the device to ensure that it is compatible with the  
modified sine waveform.  
Over-temperature Conditions  
During Inverter mode, when the Freedom HF’s internal temperature starts  
to approach its preset shutdown limit, the alarm will beep every two  
seconds and the display will show fault code E07. If the over-temperature  
condition persists, the alarm will beep once per second and the display  
will show fault code E04. The Status LED turns solid RED and the  
inverter will shut down to prevent damage to the inverter and protect the  
battery from being over-discharged. However, when the internal  
temperature drops and falls within normal operating temperature, the  
Freedom HF will recover automatically and will continue inverting.  
During AC shore power mode, when the Freedom HF’s charger  
temperature starts to approach its limit, the charging current will be  
reduced to 10A (Freedom HF 1000) or 20A (Freedom HF 1800).  
The Freedom HF also monitors the internal transfer relay temperature. It  
automatically turns on the fan when the relay starts to approach its preset  
temperature limit and turns off when it cools down. If the relay exceeds  
its preset temperature limit, the display shows a fault code E11. See “To  
reset error codes E10 to E12:” on page 5–7.

975-0390-01-01  
Battery Charging  
Battery Charging  
Battery charging is possible only when shore power is present and the  
Freedom HF unit is connected to a battery (or battery bank).  
The frequency of battery charging is determined by how much energy in  
the battery is used up during inverting. Whenever the Freedom HF detects  
a battery voltage that falls below 12.8 Vdc, the unit will begin charging  
the battery, i.e., enter into bulk and absorption stages then settle in float  
stage. If battery voltage does not reach 5 Vdc after 1 minute or 10 Vdc  
after 15 minutes as shown in the graph, the unit will terminate the  
charging process and the error code E12will show on the display screen.  
Figure 4-1 below illustrates the three-stage charging process used to  
maximize Freedom HF’s charging efficiency.  
NOTE:

Routine Maintenance  
Routine Maintenance  
Freedom HF Unit  
Minimal maintenance is required to keep your Freedom HF operating  
properly. Periodically you should:  
•
Clean the exterior of the unit with a damp cloth to prevent the  
accumulation of dust and dirt.  
•
•
Ensure that the DC cables are secure and fasteners are tight.  
Make sure the ventilation openings are not clogged.  
Batteries  
When possible, you should recharge your batteries whenever a low  
voltage warning or a shutdown occurs with the Freedom HF. This gives  
the batteries a much longer life than recharging when the batteries have  
been almost completely discharged.

Common Problems  
Buzz in Audio Equipment  
Some inexpensive stereo systems may emit a buzzing noise from their  
loudspeakers when operated from the Freedom HF. This occurs because  
the power supply in the audio system does not adequately filter the  
modified sine wave produced by the inverter. The only solution is to use a  
sound system that has a higher quality power supply.  
Television Reception  
When the Freedom HF is operating, it can interfere with television  
reception on some channels. If interference occurs, try the following:  
1. Make sure that the chassis ground stud on the Freedom HF is solidly  
connected to the ground system of your vehicle or vessel.  
2. Make sure that the television antenna provides an adequate (“snow-  
free”) signal, and that you are using good quality cable between the  
antenna and the television.  
3. Keep the cables between the battery and the Freedom HF as short as  
possible, and twist them together with two to three twists per foot.  
(This minimizes radiated interference from the cables.)  
4. Move the television as far away from the Freedom HF as possible.  
5. Do not operate high power loads with the Freedom HF while the  
television is on.

Inverter Applications  
The Freedom HF performs differently depending on the AC loads  
connected to it. If you are having problems with any of your loads, read  
this section.  
Resistive Loads  
These are the loads that the inverter finds the simplest and most efficient  
to drive. Voltage and current are in phase (i.e. in step with one another).  
Resistive loads usually generate heat in order to accomplish their tasks.  
Toasters, coffee pots, and incandescent lights are typical resistive loads. It  
is usually impractical to run larger resistive loads—such as electric stoves  
and water heaters—from an inverter due to their high current  
requirements. Even though the inverter can most likely accommodate the  
load, the size of battery bank required would be impractical if the load is  
to be run for long periods.  
5–10  
975-0390-01-01  
Inverter Applications  
Motor Loads  
Induction motors (motors without brushes) require two to six times their  
running current on start up. The most demanding are those that start under  
load (e.g. compressors and pumps). Of the capacitor start motors (typical  
in drill presses, band saws, etc.), the largest you can expect to run is 1/2 to  
1 hp (the transfer relays are rated at 2 hp.) Universal motors are generally  
easier to start. Since motor characteristics vary, only testing will  
determine whether a specific load can be started and how long it can be  
run.  
If a motor fails to start within a few seconds or loses power after running  
for a time, it should be turned off. When the inverter attempts to start a  
load that is greater than it can handle, it will turn itself off after a few  
seconds.  
Long Transfer Times  
Xantrex has observed a specific situation where the Freedom HF may  
take a long time to transfer to inverter mode when shore power fails -  
maybe 0.1-0.2 seconds. This can occur when the Freedom HF is power  
motor loads where the motor is able to freewheel when power is removed  
(e.g. a grinder). This long transfer may cause computers or other sensitive  
equipment to operate incorrectly. If power glitches must be minimized  
then Xantrex recommends that motor loads not be operated when  
sensitive equipment is being used.
