I've notified the installer and he's agreed that wiring over 14 S280's on a circuit was a mistake and has indicated that he will correct it. Of course I've been waiting for months for them to come back and correct an issue with my tilt mounts, so we will see.
So I went up on the roof today and swapped a good inverter from one array with a bad inverter from another array. The good one still worked on the new array and the bad one still shows no voltage in the location that good one used to be at. So it appears that if I do have a voltage/frequency problem, it only affects some of the microinverters. Is this possible? Or maybe my bad inverters are just misreporting the incoming voltage and frequencies?
