I have done systems in Hawaii, here is one with a 30 k PV system and with a 250k Cummins back up genny. We have a contactor in the ATS that will open if the genny is operating, this in turn sends a door open signal to the Satcon shutting it down I don't want anything effecting the genset operation so with the open created in the ATS it tricks the inverter to shut off safely. We as a policy will not run a genset and PV unless as a AC coupling system and you have some active over voltage like freq and voltage triggers.
