Operation
3.3 Current Flow
The following fi gures show the current fl ow in the MSH-M Series during different modes:
Figure 3-4, MSH Current Flow – Inverting
Inverting – The MSH inverter converts the current from the battery to power the AC loads.
Figure 3-5, MSH Current Flow – Charging and AC Pass-thru
Charging and AC Pass-thru – The MSH inverter uses current from the grid/generator to power
the AC loads, and also converts this current to charge the battery.

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