6 Freedom SW Owner’s Guide
Introduction
Generator Assist
The Freedom SW Series of inverter/chargers can operate in
tandem with a generator (or shore power) to temporarily
assist power loads with large start-up demands such as air
conditioners, water pumps etc. A Xanbus AGS is not required
for this feature to work when shore power is present to assist
the Freedom SW but the AGS is needed if a generator were to
be used in assisting the Freedom SW.
When the
Gen Support
mode is enabled and the generator’s
or shore power’s current capacity defined (in amps), the
inverter will come on-line and assist the generator or shore
power with starting and operating the load (drawing power
from the battery). The battery bank must be well charged in
order for the inverter to engage this mode. For more details,
see “Gen Support” on page 66.
Basic Protection Features
The Freedom SW has the following protection features:
•
Over temperature shutdown for critical components such
as the transformer and the power board
• Battery temperature sensor (BTS) failure/battery
temperature out-of-range fault protection
• DC output over voltage protection during charge mode
• AC transfer relay failure detection
• AC output overload and short circuit protection during
invert mode
• AC backfeed

protection
• Short circuit protection for the BTS and communication
connector ports including protection from incorrectly
inserting the remote panel communication cable plug into
the BTS port and vice versa
The Battery Temperature Sensor (BTS) provides these
protection features:
•
Battery over temperature charging protection preventing
battery charging at 60 °C (140 °F) or higher
• Charging voltage compensation based on the temperature
of the battery where the BTS is connected
1.An AC backfeed error occurs when the AC output of the inverter/charger is con-
nected or routed back to the inverter/charger’s AC input terminal or if the internal
transfer relay fails.
