    Yeah, legally that’s what it needs to do at that point in the system. if you want a solar system to be energized during an outage, you have to have what’s called a “Grid-forming” inverter (as opposed to grid-following) and it would likely need to connect up at the utility connection point

      Grid forming inverters are for solar generating plants. They are allowed to start up an unenergized grid. At that level they are a part of the utility grid.

      For homes to run of of solar when the grid is down you need to do islanding. This is a seperate beaker box feed directly by the solar and battery. This allows the house or a portion of it to stayed powered without putting power back to the grid and endangering any linemen working on the grid.
