Normal Operation
With the AC Breakers in this position, power passes
through the inverter to the connected loads. If an AC
line failure occurs, the inverter will use DC power from
the batteries to maintain the loads in the sub-panel.
Inverter Bypass Operation
With the AC Breakers in this position, power passes
directly to the loads in the sub-panel, bypassing the
inverter. In this con guration, the sub-panel loads will
continue to be powered if inverter maintenance or
service is required. If AC power from the main panel
fails while the AC breakers are in this position, the sub-
panel loads will not be powered.
AC OFF Operation
With the AC Breakers in this position, power from both
the main panel and inverter are removed from the
sub-panel. This allows the inverter, the loads in the
sub-panel or any installed equipment beyond the MMP
enclosure to be serviced.
