In that case, we're getting way off track and way more complicated :P Just put a contactor between the PV array and the POI using the NC contacts, with the coil powered off the generator. Then the PV array can never backfeed the generator because it'll be turned off anytime the generator is running.
Zeke ------------------ Thanks but I'm just trying to grid-tie a small Enphase array without ESS where the point of interconnection is on the customer side of the generator/ATS. Trying to use existing wires in place to simplify and lower costs...but the generator is my constraint because I need the PoI to be on line side of the ATS.
