Power for Most Appliances The Freedom HF inverter/charger
provides up to 1000 watts (Models
HF 1055, and Freedom HF 1055 EMS), up to 1500 watts (Freedom
HF 1500
b
), or up to 1800 watts (Modelsc Freedom HF 1800,
a
Freedom HF 1000, Freedom
Freedom HF 1800 T, and Freedom HF 1800 EMS) of continuous
modified sine wave power derived from a battery bank. It is
designed to handle loads such as microwave ovens, TVs, VCRs, and
mid-sized power tools. In addition, 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 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 HF is connected to shore power.
Comprehensive Protection The Freedom HF’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, and
•automatic switching between inverter power to passthrough shore power.
Back-up Capability If incoming shore power is interrupted by
external events like brownouts, the Freedom HF automatically
becomes an independent power source
d
that supplies quality AC to
your loads.
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 approaching the
maximum operating limit. If so, 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.
Low Power Consumption When the Freedom HF is inverting
without a load, it draws less than 1 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
HF 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 a near-zero
a
voltage
battery and an ignition-switched 20-amp auxiliary 12-volt power
b
source
.
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 HF 1055 EMS model and Freedom HF 1800 EMS model.
The inverter/charger features a 20-amp fused and switched output voltage supplied
from the inverter/charger's positive terminal. When connected to a vehicle's ignition
signal, a switched positive voltage is available to power auxiliary circuits that are required to operate only when the vehicle is operational.
Introduction
Selectable Low Battery Shutdown The low battery shutdown
for the inverter can be manually selected by the user by choosing a
low, middle, or high setting. The low setting default for low battery
shutdown is 10.5 volts except Freedom HF 1500 (PN: 806-1544).
Ignition Control The Freedom HF 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.
Table 2 lists the default settings for the Freedom HF system.

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 21.
The Freedom HF also automatically charges the battery bank that is
connected while in shore power mode. See “Battery Charging” on
page 26.
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 Power 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 Power 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 21.
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 (by 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 on the next page illustrates the battery status during
inverter mode as shown on the display panel.
Inverter Mode Setting is ON (“Standby”)
When the Freedom HF’s Inverter mode setting is turned on (“”)
and the AC source is outside the operating range or is disconnected,
the transfer switch automatically switches to inverter function. This
means that the AC output terminals will provide power from the
battery and any appliance connected to the AC output terminals will
operate.

Failure to follow these instructions can result in death or serious
injury.
The Inverter Power 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 and Inverter mode is ON:
•the AC outlets will supply power to any attached appliances
when the Inverter Power button is turned ON and
•the AC outlets will not supply power to any attached appliances
when the Inverter Power button is turned OFF
ELECTRICAL SHOCK HAZARD
Turning the Inverter mode setting to OFF and/or turning the
Inverter Power button off do 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 Power
button off when you are not using the Freedom HF.
When the Freedom HF’s Inverter function is turned off (“”) and
the AC source is outside the operating range or is disconnected, the
Freedom HF will not switch to invert mode. This means that even if
the Inverter Power button is pressed to try and turn inverter function
on, there will be no power coming from the battery to the AC output
terminals. Therefore, any appliance connected to the AC output
terminals will not operate.
Energy Saver 25-hour Automatic Shut Off
a
During invert mode, a 25-hour countdown is initiated when the AC
load drops to less than approximately 80 watts and remains below
this level. After 25 hours the inverter automatically shuts off to
reduce battery discharge and preserve battery life.

volts.
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 Power button is turned OFF then turned ON again.
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 volts AC.
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 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 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.

Operating During Transition Between Shore Power and Inverter Mode
Inverter Loads
The Freedom HF will operate most AC loads within its power rating
of 1000 watts (Freedom HF 1000), 1500 watts (Freedom HF 1500),
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
•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 1500/
1800), the audible alarm beeps once every two seconds and the
display screen shows a fault code .
Overload Shutdown When the Freedom HF’s AC load increases
to near ~1100 W (Freedom HF 1000 models) and ~2000 W
(Freedom HF 1500/1800 models), the audible alarm beeps every
second and the display screen shows a fault code . 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 motoroperated 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.
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 . If the
over-temperature condition persists, the alarm will beep once per
second and the display will show fault code . 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.
24Freedom HF Owner’s Guide
Failure to follow these instructions can damage the unit and/or
damage other equipment.
Operating During Transition Between Shore Power and Inverter Mode
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 10 amps (Freedom HF 1000 models) or 20 amps
(Freedom HF 1500/1800 models).
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 . See “To reset error codes to :” on
page 37.
Trouble Loads
EQUIPMENT DAMAGE
Some equipment may be damaged by the Freedom HF’s modified
sine wave output, which has a different wave form than utilitysupplied 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 viii for details.
•Metal halide arc (HMI) lights can be damaged.

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 volts, 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 volts after one minute or 10 volts after 15 minutes as
shown in the graph, the unit will terminate the charging process and
the error code will show on the display screen.
Figure 4 illustrates the three-stage charging process used to
maximize Freedom HF’s charging efficiency.
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.
If the unit is in inverter mode and in elevated ambient temperature
above 25 °C, you will have to reduce power draw according to the
following chart to avoid over-temperature shutdown.
Do not disassemble the Freedom HF. It does not contain any userserviceable parts. Attempting to service the unit yourself could
result in an electrical shock or burn.

This section will help you narrow down the source of any problem
you encounter. Before contacting customer service, please work
through the steps listed below:
1. Check for any error codes displayed on the display screen. If a
message is displayed, record it before doing anything further.
2. As soon as possible, record the conditions at the time the
problem occurred so you can provide details when you contact
customer service for help. Include the following information:
•What loads the Freedom HF was running or attempting to run
•What the battery condition was at the time (voltage, state
•Recent sequence of events

of charge, etc.) if known
•Any known unusual AC shore power factors such as low
voltage, unstable generator output, etc.
•Whether any extreme ambient conditions existed at the
time (temperature, vibrations, moisture, etc.)
3. If your Freedom HF is not displaying an error code, check the
following to make sure the present state of the installation
allows proper operation:
•Is the inverter located in a clean, dry, adequately ventilated place?
•Are the battery cables adequately sized as recommended in
the Installation guide?
•Is the battery in good condition?
•Are all DC connections tight?
•Are the AC input and output connections and wiring in
good condition?
•Are the configuration settings correct for your particular
installation?
•Are the display panel and the communications cable
properly connected and undamaged?
•Are all disconnects and AC breakers closed and operable?
•Have any of the fuses blown in the installation?
4. Contact customer support for further assistance. Please be
prepared to describe details or your system installation and to
provide the model and serial number of the unit.
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.

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.
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
A specific situation has been observed where the Freedom HF may
take a long time (~ 0.1–0.2 seconds) to transfer to inverter mode
when shore power fails. This can occur when the Freedom HF is
used to power motor loads where the motor is able to “freewheel”
when power is removed (for example, a grinder). This long transfer
may cause connected computers or other sensitive equipment to
operate incorrectly. To avoid this effect, it is recommended not to
connect motor loads together with sensitive equipment to the
inverter for power.
