That being said, why couldn't a couple of big contactors that would flip and prevent energy to being sent back to the utility be able to be installed and prevent that. Really not a big deal, but supposedly illegal here. Yet if you have backup battery system, it can operate with no utility power. Not sure how they do that.

They are called transfer switches commonly used with generators. If your system automatically drops out, sure seems like it could be stand alone.
