Safety
viii 975-0390-01-01
5. Do not operate the Freedom HF if it has received a sharp blow, been
dropped, or otherwise damaged in any way.
6. Do not disassemble the Freedom HF. It contains no user-serviceable
parts. 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.
NOTES:
1. 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.
2. 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.
EXPLOSION HAZARD
Working in the vicinity of batteries is dangerous. Batteries
generate explosive gases during normal operation. Before
servicing the unit in the vicinity of the battery, read this
manual and follow the notes belowexactly.
Failure to follow these instructions can result in death or serious
injury.

975-0390-01-01 ix
Personal Precautions When Working With Batteries
NOTES:
1. Remove (or do not remove) cell caps while charging and follow
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.

1Introduction
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.

1–2 975-0390-01-01
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:
•Thelow battery voltage alarm and shutdown prevents your
batteries from becoming completely discharged.
•Thethree-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.

Independent Power System
975-0390-01-01 1–3
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 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.
Charging 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).
