For an update, the installer came this morning and swapped out the P300s for the proper P400s. I took the opportunity to show them the piercing star grounding washers that came with the optimizers and explained how they are to be used to, you know, actually ground the equipment. Sigh. But, anyway, I've now got properly sized optimizers for my Sunpower E-20 327 panels, they are grounded properly, and even my wire management under the panels is cleaner.
But, the error remains. ERROR 31: AC VOLTAGE TOO HIGH. As suspected, the root problem is in the inverter. SolarEdge is sending out a "new board", whatever that means.
And every hour my meter continues to tick in the wrong direction.....
