Introduction
Key Features
Power for Most Appliances The Freedom HFS inverter/charger
provides up to 1000 wattsaor up to 2000 wattsbof continuous utility
grade, sine wave power derived from a battery bank. It is designed
to handle loads such as microwave ovens, TVs, DVD/Blu-ray
players, and power tools. In addition, the Freedom HFS’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 shore power from recreational facilities such as boat
docks or campsites to ensure power is always available.
The built-in charger also automatically charges the battery bank
when the Freedom HFS is connected to shore power.
Comprehensive Protection The Freedom HFS’s built-in
protection features safeguard your batteries and equipment, such as:
• the low battery voltage alarm and shutdown prevents your
batteries from becoming completely discharged
• the three-stage charging capability ensures that batteries
receive efficient charge
• when shore power is available, inverter power switches
automatically to shore power in milliseconds allowing
continuous operation of connected equipment
Back-up Capability If incoming shore power is interrupted by
external events like brownouts, the Freedom HFS automatically
becomes an independent power sourcecthat supplies utility grade
AC power to your loads.
Overload Alarm and Shutdown During inverter mode, the
Freedom HFS automatically alerts you if the loads that are
connected and drawing power from the unit are close to
approaching the maximum operating limit. If so, the Freedom HFS
automatically shuts down when the maximum operating limit is
exceeded.

975-0727-01-01 3
Introduction
Over temperature Alarm and Shutdown During inverter mode,
the Freedom HFS automatically alerts you if it is overheating and
approaching the over-temperature shutdown limit.
The Freedom HFS automatically shuts down when the limit is
exceeded.
Low Power Consumption When the Freedom HFS is inverting
without a load, it draws less than 0.6 amp of current from the battery
(or battery bank).
This feature allows the unit to operate without draining too much
stored energy.
Battery-friendly Charging For the inverter to perform
effectively, the batteries must be charged correctly. The Freedom
HFS 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 HFS—unlike many
chargers—also has the ability to recharge a near-zeroavoltage
battery and an ignition-switched 20-amp auxiliary 12-volt power
sourceb.
Selectable Low Battery Shutdown The low battery shutdown
for the inverter can be manually selected by the user by choosing a
low (10.5 V), middle (11.8 V), or high (12.1 V) setting.
Ignition Control The Freedom HFS provide two user-selectable
ignition control method:
•Ignition Lockout: The Freedom HFS features the ability
to inhibit the inverter from operating in the absence of a
voltage signal from a vehicle's ignition circuit. This is
particularly useful if the inverter is required to operate only
when a vehicle's engine is running.
•Ignition Auto-on: The Freedom HFS can automatically
turn the inverter on and off with the vehicle's ignition
circuit.
Inverter Power Save The Freedom HFS has the ability to
automatically turn off after 25 hours of continued operation of loads
that are under 50 watts. It is designed to, in conjunction with LBCO,
to prevent the battery from deep discharge.
a.Near-zero or dead batteries can be recharged. However, some batteries which have
been left uncharged for days can become severely damaged thus, recharging is futile.
b.Available on the Freedom HFS 1055 120VAC EMS model (PN: 807-1055-02) and
Freedom HFS 2055 120VAC EMS model (PN: 807-2055-02). The inverter/charger
features a 20-amp fused and switched output voltage supplied from the inverter/char-
ger's positive terminal. When connected to a vehicle's ignition signal, a switched pos-
itive voltage is available to power auxiliary circuits that are required to operate only
when the vehicle is operational.
