The output is a modified sine wave and is
compatible with most appliances, tools and
other 120 VAC equipment. (Note: Certain laser
printers, breadmakers, digital clocks and
small battery chargers may not operate on
modfied sinewave.) An idle mode reduces bat­tery power consumption when loads are re­moved from the inverter. There is a low battery
cutout protection circuit and
momentary surge power of more than twice
the inverter rating for starting electric motors.
High efficiency insures the longest possible
battery life between charges.

They are designed to rapidly and optimally
charge wet, gel, or Absorbed Glass Mat
(AGM)** cell deep-cycle batteries. Battery
charging is automatically accomplished in 3
stages: Bulk Charge, Acceptance Charge and
Float Charge.

Using a Remote Control Panel or Link
Instrumentation, a manually engaged
Equalizing Charge cycle is possible. Simple,
automatic operation is made possible by the
microprocessor in the Freedom Inverter/
Charger. I n most cases, no attention or
maintenance is required.

reset by pushing the button back in. The
fault must be removed before resetting
the circuit breaker. Integral branch circuit
rated breakers are reset by setting the
appropriate breaker switch to the “on” po­sition. The fault must be removed before

Inverter Idle CircuitInverter Idle Circuit

This automatic energy saving feature
reduces battery power consumption when no
AC load is present. Response from idle is
instantaneous. In most cases, the operation of
the idle circuit is not noticeable. Use of the
Remote Control Panel or Link Instrumentation
allows the idle threshold to be adjusted. The
unit does not put out 120 volts when in idle. To
bring the unit out of the idle condition, apply a
load.

Low and High Battery ShutdownLow and High Battery Shutdown

Low and High Battery Shutdown

Low and High Battery ShutdownLow and High Battery Shutdown

When in inverter mode, if the battery
voltage drops to 10.0 volts, the inverter will
automatically shut off. Charge the batteries to

13.5 volts to automatically resume operation.

Voltage shut down also occurs for a high
battery condition at 15.5 volts. Operation will
resume automatically when the battery voltage
drops below 15.5 volts. Check all DC sources
on the system for the reason for the excessive
voltage.

Power SharingPower Sharing

Power Sharing

Power SharingPower Sharing

When connected to an external AC
source the battery charger and transfer
functions are engaged. A unique Power
Sharing feature automatically reduces the AC
power consumption of the battery charger
allowing necessary AC power to go to the load.
This prevents the source AC INPUT circuit
breaker from tripping within the specified rating
of the AC circuit breaker.

The Power Sharing set point of each unit
has a factory default setting of 30 Amps. This
can be changed using the Remote Control
Panel or Link Instrumentation.

When external AC power is not available
and the INVERT switch is ON (either through
the auxiliary switch or the INVERT button on
the remote), the inverter will automatically turn
ON. If the INVERT switch is OFF (the INVERT
LED will not be illuminated), the inverter will be
OFF.

If installed with the Remote Control Panel
or Link Instrumentation, the unit will be set up
and controlled from the remote. Refer to the

• When the LED is solid green, the unit is
in invert mode. This occurs by pressing the
INVERT switch for (3-5 seconds).

• The CHARGE push-button switch is lo­cated on the fornt of the unit.

When external AC is applied to the AC in­put of the unit, the charger automatically turns
ON. The CHARGE LED will be solid green.

• When the LED is blinking slowly, (1 time
per second) the charger is ready, but external
AC power is not available.

• Press the CHARGE switch again to turn

the charger OFF. The charger defaults to ON
when operation without a remote or with the
Freedom Remote Control Panel.

• When the LED is OFF, the charger has
been manually turned OFF. This can only be
accomplished while AC power is being
supplied.

NOTE: When AC power is available, the
default setting for the charger is ON. If the unit
was manually turned OFF and AC power is in­terrupted and becomes available again, the
charger will return to ON.

To achieve

50% cycling you should
calculate your Amp-hour consumption
between charging cycles and use a battery
bank with twice that capacity**. Each AC
appliance or tool has a rating plate on it and will
be rated in either AC Am ps o r W atts or AC VA
( Volt-Amps) apparent power. To calculate Amp­hour consumption, use one of the formulas to
the right to calculate the DC Amp-hour draw
for a 12 volt system.

Calculate the Amp-hours for every AC
appliance or tool that will be operated on the
inverter. This will provide the total number of
Amp-hours used between recharges. Size the
battery bank using this number as a guideline.
A good rule to follow is to size the battery bank
a minimum of 2 times larger than the
total Amp-hour load requirement. Plan on
recharging when 50% discharged.

**Batteries are typically charged to 85% of full
charge when charging with alternators without 3-stage
regulators.

Battery ChargingBattery Charging

Battery Charging

Battery ChargingBattery Charging

Completely charging wet cell deep-cycle
batteries requires the battery voltage to be
raised beyond what is known as the gassing
point. This is the voltage at which the battery
begins to bubble and gas is given off. If
charging stops short of this point, sulfate is left
on the plates and deterioration of the battery
begins. The gassing point will vary with battery
temperature.

At 77 degrees F, the gassing point of a 12
volt battery is about 14.0 volts.

AGM and Gel cell batteries must not be
charged to their gassing point. In fact, high
voltage charging which gasses these batteries
is harmful to them. They typically require a
lower bulk charge voltage and a higher float
voltage than wet cell batteries. Consult the
battery manufacturer for specifications.

For safety purposes, the chassis of the
inverter/charger must be connected to your AC
ground system. Use 8 AWG bare copper or
green insulated wire, strip one end and use a
screwdriver to secure it to the chassis ground
bonding lug on the side of the unit. This wire
will connect to the ground in your AC electrical
system. Make sure the connection is clean and
tight.

The system AC ground bonding terminal
is located on the front of the unit under the
wiring cover at the bottom of the unit. This
connector is for the bare copper or green
ground wires from the AC branch circuit supply
and to the AC loads or distribution panel. It is
important that these AC input and AC output
ground wires connect to the AC ground bus in
the circuit breaker panels.

For safety purposes and NEC code
requirements, the Freedom Combi unit
internally bonds the AC output neutral (white)
to the AC output ground (green), when the unit
is OFF or in the inverter mode. When
incoming AC power is applied and the transfer
switch is engaged, the internal neutral-to­ground bond is automatically lifted.

When external AC power is applied, the
grounding system is connected to the source
power ground, where neutral and earth ground
are bonded together. This technique insures
safety in all conditions and conforms to the
requirements of the NEC.

Some installations require heavier
grounding wire. Conform to local and national

terminal cover from the unit and attach the
battery cable. T ighten the battery terminal bolts
to a torque value between 160 inch-pounds
and 180 inch-pounds. Replace the cover for
the positive terminal.

The negative (-) cable should be
connected directly to the negative post of the
house or auxiliary battery bank or the ground
side of a current shunt. Tighten securely.

The positive (+) battery cable must be
fused and connected to the positive post of the
house or auxiliary battery bank, or through a
selector switch to one or more battery banks.

A spark may be generated when the final
battery connection is made. This is normal; do
not be alarmed. However, do not make the final
connection in the presence of flammable
fumes.

If multiple battery banks are to be
charged, a battery bank selector switch can be
installed, allowing the banks to be charged
either individually or simultaneously. A solenoid
can also be used. The PathMaker Battery
Combiner, b y Heart Interface, may be used to
connect multiple battery banks. The
PathMaker battery combiner is available from
your Heart dealer.

If multiple batteries are used, the
interconnecting jumper cables must be the
same A WG or larger as those connected to
the inverter/charger.

NOTE: If installing in a vehicle, do not use the
vehicle frame as the negative conductor.
