Most string inverters have a normal voltage operating range, but that range can usually be extended by 10% or so. However, AC overvoltage issues can occur, leading to inverter shutdowns or even damage to appliances. Enphase Microinverters, like all utility-interactive inverters, sense voltage and frequency from the AC grid and cease. . I'm using a SolarEdge inverter and after it synced with the optimizers, we got a "AC Voltage Too High" error (and apparently it also burnt out his test meter, or maybe it was a coincidence, but it would no longer turn on). However, like any electronic device, they can experience issues.
