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.
INV Bypass/AC Output OFF (INV Input ON)
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 loads in the sub-
panel, or any installed equipment beyond the MP
enclosure to be serviced. To service the inverter,
the Inv Input breakers also must be turned OFF.
Inverter Bypass Operation
With the AC breakers in this position, power passes
directly to the loads in the sub-panel, bypassing
the inverter. When the inverter input breaker is
ON, the batteries will continue to be charged. If
inverter maintenance or service is required, the
inverter input breaker must be turned OFF. If
AC power from the main panel fails while the AC
breakers are in this position, the loads in the sub-
panel will not be powered.
