When powering a home with a portable generator utilizing an inlet, generator breaker in the main panel and a mechanical interlock to prevent a back feed to the utility, is there anything that must be done when there is also a PV system in place?
I don't know much about PV systems but this one has roof panels, an inverter, a seperate meter and disconnect at the meter and some kind of controller near the main panel in the basement.
I'm thinking as long as the interlock prevents the generator from back feeding the utility it should not be an issue. And if that is the case, if the generator is feeding the home and the sun is shining will the solar synch up with the generator and just keep feeding the house? That seems unlikely but I really don't know. I'm guessing the solar system should just be shut down when the generator is running and wonder if it would be damaged if it were not shut down.
