Charger Back-off
– When the AC loads increase, the MSH3012RV inverter reduces or stops the
battery charge current to allow the grid/generator to continue powering the AC loads.

Charging and AC Pass-thru
– The MSH3012RV inverter uses current from the grid/generator
to power the AC loads, and also converts this current to charge the battery.
