I have a whole-house portable generator setup to backfeed my panel via an interlock kit. I know solar panels are set to somehow disconnect when POCO power goes down. But can they be disconnected in addition to disconnecting POCO power so as to isolate the generator feeding emergency power to a house?
My install has 3 opportunities to disconnect the array from the grid.
There's a dual breaker in my load center. There's a lock-out-tag-out throw switch next to the meter outside and there's another dual breaker in an external load center next to said switch and meter.
It would be a very good idea to disconnect the array prior to energizing your home from the portable generator. Portable gen sets aren't world renowned for their power output quality. And your inverters will probably struggle to keep up with it.
