To connect our inverter to the panel, we simply connected our inverter to a receptacle which was running on the desired phase (L2 in our case). Ideally, this receptacle should not be on a circuit containing a GFCI or arc fault breaker and should not have any loads between the inverter and the panel.
Please consider the following situation:
In the above situation, the 15A breaker is not protecting you. If the inverter can supply more than 15 amps, then the wires between panel and the inverter could be carrying up to 27 amps in the above diagram which would be over the rated amperage of the wires!
Connection Steps
- Turn off the main power circuit on panel!
- Turn off all circuits
- Ensure all 240v breakers are OFF. Any 240v breakers that feed sub panels can be kept on. Ensure 240v breakers on sub panels are OFF.
- Connect inverter to receptacle on desired phase. (Ideally a circuit not protected by a GFCI or arc fault breaker)
- Power on inverter
- Turn on critical circuits on panel.

To connect our inverter to both phases we will need to connect to two different receptacles on different phases. We will need to ensure all 240v breakers are turned off.
