How it Works

The generator starts automatically when the battery voltage drops to less than the Self-Start Voltage. The generator stops automatically when the output current is less than 20 amps for more than two minutes in constant current mode, or stops automatically after 50 minutes in constant voltage mode.

Not Running	Mode	Self-Start Voltage
Green LED flashes QUICKLY	Higher	72v, 60v, 48v, 24v, 12v - Lifepo4 3v/cell - Li-ion 4v/cell - AGM/Lead-Acid 2v/cell
Green LED flashes SLOWLY	Lower	69v, 57.5v, 46v, 23v, 11.5v - Lifepo4 2.875v/cell - AGM/Lead-Acid 1.91v/cell
Generator is Running	Mode
Green LED is ON STEADY	Constant Voltage AGM / Lead-Acid	58v/28.5v constant output voltage. Generator will stop automatically after 50 minutes of operation.
Green LED flashes SLOWLY	Constant Current Lifepo4 / Li-ion	~54v/27v output voltage. Generator stops automatically when output current < 20 amps for > 2 minutes.

To change Self-Start Voltage Mode - observe if the Green LED is flashing quickly or slowly. The generator must not be running, and the battery must be connected.
