– If AC loads are added that are above the capability of the grid/generator, the
MSH converts current from the battery and combines it with the current from the grid/generator
to power the additional AC loads.

– If the battery is being charged externally (i.e., solar, wind, or hydro), the
MSH converts any excess current from the battery to power the AC loads and reduce the current
from the grid/generator.

– When the AC loads increase, the MSH-RE inverter reduces or stops the battery
charge current to allow the grid/generator to continue powering the AC loads.
