Your line voltage seems reasonable. But I have had similar symptoms from high line voltage
at times of peak PV production. One of your line to neutrals is a bit high a 126V, my inverter
also monitored that. If your inverter connects to neutral it might have that monitor. With no
current in the inverter lead, a transformer/variac could be wired to shift a balanced signal to
the inverter. Bruce Roe

What did the installer and SolarEdge say when you told them all you've done and researched ?Leave a comment:

New Se 7600H inverter Drops out 1 to 5 times a day
Hello Everyone, I just had a 8.7kw solar system installed by a solar company. The spec are 29 300w panels, 29 p320 optimizers, and a se7600h HD wave inverter. The inverter is 4ft from my 200 amp meter breaker panel, the 40amp 240 inverter breaker is the last breaker in the panel. I have a monitoring instrument called sense that connects to my mains and solar with ct's so I can monitor usage and solar output in real time. The very first day I seen the inverter drop out for 1.5 minutes, the next day it drop out 5 times all 1.5 minutes. I'm in central California with cloudy rainy cool weather mix. It seems to be when the production comes close to max. one day I caught it when it drop out and seen the code
18XB5. I called the installer with this. No reply so I called solaredge and made a ticket, called solaredge the next day
and was told that code ment I had a harmonics problem and to call pg&e. So I research line harmonics. Them bought a multimeter with a oscillator and check my breaker panel.
sine wave looked good smooth with no distortion, I noticed the neutral wire for the inverter was connected to the earth ground buss bar so I checked voltage L1 had 118v, L2 had 126v. so then I checked voltage with the neutral buss bar L1 was123v L2 123v 246v total, so moved the neutral to the neutral bus. I know earth ground and neutral can be tied together but in my panel that are not bonded other than attach to the panel that is painted, Still the inverter drops out. Then I found some have had luck with capacitor, surge protector. Well that didn't help. Any idea what could be the problem.
also the inverter didn't store any codes
