Key Features
Power for Most
Appliances
The built-in transfer switch automatically
transfers between inverter power and shore
power from recreational facilities such as
campsites to ensure power is always
available.
Back-up
Capability
If incoming shore power is interrupted by
external events like brownouts, the Freedom
XC automatically becomes an independent
power source1that supplies utility grade AC
power to your loads.
1Assuming the inverter/charger is connected to a battery source with an adequate charge at the time of the
power interruption.

Materials List
975-1175-01-01 3
Comprehensive
Protection
The Freedom XC’s built-in protection features
safeguard your batteries (from unnecessary
drain) such as the low battery voltage alarm
and shutdown and protect equipment such as
a configurable AC transfer speed.
nSelectable Low Battery Shutdown:
The low battery shutdown for the
inverter/charger can be manually
selected by the user from 10.1 to
12.8VDC.
nLow Voltage Shutdown Delay Timer:
Configurable from 1 to 300s to reduce
an unnecessary shutdown of inverter
operation such as during cranking or
other brief but heavy discharge of
battery.
nInverter Power Save: The Freedom XC
can be programmed to automatically
turn off after 1 to 25 h of continued
operation of loads that are under 50W.
It is designed, with LBCO (low battery
cut off), to prevent the battery from deep
discharge.
Configurable AC
Transfer Speed
The Freedom XC allows two speed settings
for the AC transfer from Grid Mode to Battery
Mode and vice versa which avoids nuisance
resetting of appliances. The normal transfer
rate is for common appliances and the faster
transfer rate is designed for more sensitive
digital equipment like a desktop computer.
Overload Alarm
and Shutdown
During Battery Mode (also called Inverter
Mode), the Freedom XC 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 XC automatically shuts
down when the maximum operating limit is
exceeded. See the Troubleshooting section
for precautions.
Over temperature
Alarm and
Shutdown
During Battery Mode, the Freedom XC
automatically alerts you if it is overheating
and approaching the over-temperature
shutdown limit. The Freedom XC
automatically shuts down when the limit is
exceeded. See the Troubleshooting section
for precautions.

Materials List
4 Freedom XC 1800 (12VDC) Owner's Guide
Built-in Charge
Formulas
For the inverter/charger to perform at the
highest level, the batteries must be charged
correctly. The Freedom XC has optimized
algorithms for flooded, gel, AGM, custom,
and lithium iron phosphate [LFP (or LiFePO4)]
batteries.
Manual
Equalization
Over a period of time, the cells in a flooded
battery can develop uneven chemical states.
This can result in a weak (undercharged) cell
which, in turn, can reduce the overall capacity
of the battery. To improve the life and
performance of a non-sealed, flooded battery,
the Freedom XC multi-stage charging cycle
includes a manual equalize mode that can be
used, if recommended by the battery
manufacturer.
Dead Battery
Charging
Another feature of the Freedom XC is dead
battery charging. This is the ability to
recharge batteries, even if the battery voltage
has reached 0VDC.
Ignition Control The Freedom XC provides two user-
selectable options for ignition control:
nIgnition Auto-on: The Freedom XC
can automatically turn the
inverter/charger on and off in tandem
with the vehicle's ignition circuit or a
manually operated remote switch.
nIgnition Lockout: The Freedom XC
features the ability to inhibit the
inverter/charger from operating in the
absence of a voltage signal from a
vehicle's ignition circuit. This is
particularly useful if the inverter/charger
is required to operate only when a
vehicle's engine is running.
Configurable AC
Output Frequency
and Voltage
The Freedom XC is factory set to 60Hz AC
output frequency and 120V AC output
voltage. It can be configured to 50Hz for use
in regions outside the USA and Canada. The
AC voltage setting can also be configured to
either of three settings: 108, 110, or 120volts.

Materials List
975-1175-01-01 5
Load
Management
The Freedom XC has a built-in 20A transfer
relay that connects the inverter output or AC
input from the AC generator to the loads.
Because the usual AC power sources such
as small generators often have limited current
availability, having the capability to manage
your AC loads is extremely valuable. The
Freedom XC provides a number of features to
facilitate this.
nThe charger is power factor corrected to
use AC current as efficiently as
possible. Minimizing the AC current
used by the charger means more current
is available for your AC loads.
nThe Freedom XC has a power share
feature which prioritizes your AC loads
by reducing the charge current and
maintaining the total input current to
less than the breaker setting.
