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.
