This owner’s manual describes the
Freedom 458 Series
Inverter/Chargers from
Xantrex. These units perform three distinct
functions:
1. DC to AC power inverting.
2. Automatic transfer switching between
inverter power and incoming AC power.
3. Automatic three-stage battery charging
plus manual battery equalizing.
• The inverter provides regulated 120 volt AC
power at a crystal controlled frequency from a
deep cycle battery bank and is rated at:
Freedom 10 1000 watts
Freedom 15 & 15D 1500 watts
Freedom 20 & 20D 2000 watts
Freedom 25 2500 watts
Freedom 30 3000 watts
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 modified
sine wave.) 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 start-
ing electric motors. High efficiency ensures the
longest possible battery life between charges.
• The internal transfer switch allows the
Freedom Inverter/Charger to be connected to
an external AC source and transfer the source
power through directly to the loads. When the
external AC power source is disconnected, the
transfer switch allows automatic switching
back to the inverter.
INTRODUCTION
The Freedom Inverter/Charger operates
as a self-contained backup power system—
just add batteries.
• Freedom battery chargers are electronically
controlled and rated at a maximum output
current:
Freedom 10 50 amps DC
Freedom 15 & 15D 75 amps DC
Freedom 20 & 20D 100 amps DC
Freedom 25 130 amps DC
Freedom 30 140 amps DC
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
three 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 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).
