Low Battery Disconnect (Aux Mode) - Alpha Group OutBack Power FLEXmax Series Owner's Manual

Operation

Low Battery Disconnect (AUX Mode)

This mode disconnects "auxiliary" loads from the batteries in the event of low voltage. These are
separate from the usual loads. Auxiliary loads are controlled by the AUX output, usually by a larger
relay. When the battery voltage falls below the DISCONNECT VOLTS setting, the AUX loads are
disconnected. When the voltage rises above the RE-CONNECT VOLTS, they will be reconnected.
Any loads not controlled this way, such as an inverter, may continue discharging the battery.
