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 confi 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.
