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 bat-

tery power consumption when loads are re-

moved 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. In most cases, no attention or

maintenance is required.

Electronic ProtectionElectronic Protection

Electronic Protection

Fast-acting electronic circuits protect

the inverter from overloads and short circuits.

Other protection includes a low and high

battery voltage cutoff and automatic shutdown

if an over temperature condition occurs. When

the fault condition is corrected, the unit will

automatically reset. Example: remove

overload, charge batteries or allow to cool.

**Battery type selection is set on the front of the unit

or with an optional remote

(Remote Control Panel or

Link Instrument).

Circuit Breaker ProtectionCircuit Breaker Protection

Circuit Breaker Protection

The Freedom Inverter/Charger is

supplemental breaker protected.

The INVERT/CHARGE breaker on the front

of the unit protects against sustained inverter/

charger over current conditions.

These breakers are reset by pushing the

button back in.

The output circuit breakers protect the output

AC circuits. Models are available with one or

two outputs.

Thermostat Controlled CoolingThermostat Controlled Cooling

Thermostat Controlled Cooling

Freedom Inverter/Chargers are equipped

with a thermostatically-controlled fan that cools

the unit so it can operate continually at its rated

THINGS YOU SHOULD KNOWTHINGS YOU SHOULD KNOW

THINGS YOU SHOULD KNOW

Units with only supplemental circuit breakers

between the unit and the load. Appropriate

wire gauges must be used throughtout the in-

stallation. Refer to NEC specifications.

Inverter Idle CircuitInverter Idle Circuit

Inverter 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

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

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.

*Note: Supplemental circuit breakers are

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” po-

sition. The fault must be removed before

resetting the circuit breaker

If a 30-Ampere service supplies the in-

put to the unit, a model with integral

branch circuit rated breakers allows di-

rect wiring from the unit to the load.

recommendations for maintenance.

Never allow the top of the battery plates to

be exposed to air, as contamination of the cell

will result. Keep the top of batteries clean.

Always provide adequate ventilation for the

battery storage compartment.

Do not use ordinary car batteries or

engine starting batteries with your inverter/

charger. Beware of any battery that is rated in

Cold Cranking Amps (CCA). This is a rating

which applies only to engine starting batteries.

In general, most wet cell batteries that are

described as hybrid type batteries, suitable for

either engine starting or deep-cycle

applications, are a compromise and will have

limited life if deeply discharged.

Deep-cycle batteries are usually rated in

Amp-hours. The Amp-hour rating is based on

a 20-hour discharge rate, therefore, a 100

Amp-hour battery can deliver 5 Amps for 20

hours. If the discharge rate is greater than 5

Amps, the available Amp-hours are de-

creased. For example, if the load is increased

to 100 Amps, only about 45 Amp-hours will be

available at this rate of discharge.

Deep-cycle batteries can be discharged

about 80% of capacity before damage occurs.

Shallow cycling will result in much longer

battery life. Calculating a battery bank size

based on 50% discharge cycling is generally

considered to be a good compromise between

long battery life and size.

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 Amps or WattsorAC VA

(Volt-Amps) apparent power.To calculate Amp-

hour 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.

Battery ChargingBattery Charging

Battery 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.

Bulk ChargeBulk Charge

Bulk Charge

During the bulk

charge stage most of the energy that has been

consumed during discharge is returned to the

battery bank. This phase is engaged as soon

as the battery charger is activated. Full rated

charger current is delivered to the battery bank

until the acceptance charge voltage limit is

reached. This results in a relatively rapid re-

charge.

Generally, a wet cell battery bank should

not be charged at a rate which exceeds 25% of

its capacity.

The

acceptance stage immediately follows the bulk

charge stage. During this stage the

battery voltage is held constant at the bulk

charge voltage limit and the current gradually

ramps down. During this stage the battery is

accepting its final amount of charge current

and the last

of the sulfate on the plates is

removed.

The acceptance stage lasts until the

Maximum acceptance time is 1 hour for

wet and AGM cells and 3 hours for gel cells.

Gel cell acceptance time can be longer

because they are less likely to gas. Expect wet

When the

acceptance stage is terminated, either

because the charge current ramped down to

the transition point or the timer engaged, the

charge current will shut off. The unit monitors

the battery voltage while it drifts down from the

acceptance charge voltage limit. When it

reaches the float voltage set point, the float

charge stage is engaged.

The float charge stage holds the battery

voltage constant at a preset lower level, where

it is safe for long term battery maintenance.

During the float charge stage, the full output

current of the battery charger is available to

operate any DC appliances that may be on the

system, while constantly maintaining the float

charge voltage.

The battery charger remains in the float

The equalizing charge is a timed, 8-hour

cycle. The cycle can be ended early by inter-

rupting the AC power to the charger at any

time during the cycle. Equalizing should only

be engaged after the batteries have been fully

charged by a normal battery charging cycle.

During this equalizing stage, the battery

voltage will increase to the equalize voltage.

This will cause the battery bank to gas

profusely and will accomplish the following:

1. Removal of residual sulfate.1. Removal of residual sulfate.

1. Removal of residual sulfate. Each time a

battery is cycled (discharged and charged), a

small amount of sulfate is left on the plates.

Over time, this gradual build-up of sulfate will

compromise the performance of the battery.

By applying an equalizing charge, the sulfate is

returned back to the electrolyte, raising the

specific gravity and fully exposing the active

material of the plates.
