Mode Settings
Built-in low voltage and under voltage protection preserves lift gate battery power to keep the EPJ from depleting the
LG batteries. Four different mode settings are available to customize how to utilize the available power from the liftgate
battery based on fleet's operations.

If LG batteries are <10.2V for
three seconds, the inverter will
automatically shut off to
protect the batteries. The
inverter will power back up
when input battery voltage is
raised to normal operating
ranges.

If mode is set to P02 or P04 where the power save mode is active, when no AC load is connected to the unit, the inverter
will pulse two sinewave AC Output cycles every 4 seconds to detect if AC load is present. If it senses AC load connected
is >10W, it will continuously provide AC Output power. Unit will switch back to pulsing two AC Output cycles if it senses
the AC Output load drops to ~ 6W or below.
