Introduction
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
the BTS is connected to
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.
