That is what I was thinking, but how will the contactor coils "know" when the ATS switches to inverter power. I'm thinking I need to use an AUX relay or a series of relays to produce the desired result. I don't think it will be necessary when going from solar to generator in this case, but maybe. I guess the question is how to activate the time delay any time the ATS switches over. That would be the easiest solution maybe.
I'm probably looking at a quad Conext XW+ system here. Even at over 100A @ 240V continuous rating I'm anticipating some startup issues with all those motors (I forgot to mention well and pressure pumps also!)
