Using the correct cable size is critical to achieving the rated
performance of the Freedom XC unit. When starting a heavy load the
Freedom XC can draw current surges from the battery of up to 400A. If the
DC wiring is too small the voltage drop from this surge will result in a
voltage at the Freedom XC terminals that is too low for the Freedom XC to
operate correctly. The Freedom XC may appear to operate correctly with
smaller cables until a heavy load such as a microwave or refrigerator
attempts to start - then the unit may work correctly sometimes and not work
correctly other times.

Basic Installation Procedures
DC Disconnects and Over-Current Devices
The DC circuit from the battery to the Freedom XC must be
equipped with a disconnect and over-current device. This usually
consists of a circuit breaker, a “fused-disconnect”, or a separate fuse
and DC disconnect. Do not confuse AC circuit breakers with DC
circuit breakers. They are not interchangeable. The rating of the fuse
or breaker must be matched to the size of cables used in accordance
with the applicable installation codes. The breaker or disconnect
and fuse should be located as close as possible to the battery, in the
positive cable. Applicable codes may limit how far the protection
can be from the battery.
Batteries
The Freedom XC uses 12-volt battery banks. Every Freedom XC
system is recommended to have a deep-cycle battery or group of
batteries with a total capacity of 100 Ah or more which provides the
DC current that the Freedom XC converts to AC.
Ground Fault Circuit Interrupters (GFCIs)
A GFCI is a device that de-energizes a circuit when a current to
ground exceeds a specified value that is less than that required to
blow the circuit breaker. GFCIs are intended to protect people from
electric shocks and are usually required in wet or damp locations.
Installations in marine and recreational vehicles require GFCI
protection of branch circuits connected to the AC output of the
Freedom XC.
The following GFCI will work correctly with the Freedom XC
whether installed on the AC panel or in the inverter’s AC output
distribution wiring system.
