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

Flow
The following
fi
gures show the current
fl
ow in the MSH-RE Series during different modes:
Inverting
– The MSH inverter converts the current from the battery to power the AC loads.
• Load Support VDC
– In this mode, an external DC source (i.e., solar, hydro, wind, etc.,) is
providing more current than needed, causing the battery bank voltage to rise. The inverter/
charger reduces the incoming AC current and uses current from the batteries in an effort to
keep the battery voltage from rising above the temperature-compensated battery type setting
on the remote control.
Info:
The charger must be enabled (not in Charger Standby) and in the Absorb, Float,
or EQ charge modes in order for the Load Support VDC feature to be active.
