Sol-Ark › GEN port and two-wire generator start relay
AC-coupled PV drops loads or feeds during generator run
manufacturer says
Symptoms
- With microinverters or a string inverter coupled on the load side, the Sol-Ark shows no AC-coupled production, may cut power to loads for several seconds when the utility drops, and the GEN terminal is unusable
- With AC-coupled PV on the GEN port and a generator on the same port, the PV can keep feeding or latch onto the generator's sine wave once the generator runs
