Setup
STANDBY MODE
Current from the grid/generator to the inverter’s
AC input is used to power the inverter’s AC loads
and to charge the battery.
Example below:
Current to inverter input (AC Input)
= 20 Amps AC
Current to power the AC loads (AC Load)
= 10 Amps AC
Current to charge battery (Inv/Chg Amps)
= 10 Amps AC

LOAD SUPPORT MODE
(MSH Series Only)
The MSH Series uses current from the battery to
assist in powering the inverter’s AC loads and to
reduce the current from the grid/generator.
Example below:
Current to inverter input (AC Input)
= 10 Amps AC
Current to power the AC loads (AC Load)
= 20 Amps AC
Current from battery (Inv/Chg Amps)
= -10 Amps AC

INVERT MODE
Current from the battery is used by the inverter
to power the inverter’s AC loads.
Example below:
Current to inverter input (AC Input)
= 0 Amps AC
Current from battery (Inv/Chg Amps)
= -10 Amps AC
Current to power the AC loads (AC Load)
= 10 Amps AC
