great news - one of the solar companies just called me back and is willing to help out. They figure it's an inverter failure, but they should have someone out to look later this week. 🙌

Just watching triathlon has me exhausted.

String 2? (bottom pair): "NA" isolation value and wouldn't provide more than 14VDC to the inverter. No information on the SetApp Isolation Status page. (For reference, the functional second inverter indicates a value of 11,000KOhm isolation value)
Both strings offered up their proper idle voltage, 14 and 12VDC respectively - corresponding to the number of optimizers on each string so I think the optimizers are okay.

I found:
String 1? (top pair): low isolation value of 194.37kOhm (ground fault?) but optimizers would spool up to 380VDC when the inverter was switched on. Inverter would cycle through its 5 minute Grid Monitoring and then return to Idle. The inverter reported a potential fault seemingly on the homerun at 99.83% of the string length.

So to follow up on this whole deal, I tried isolating the two strings. Turns out, the strings weren't labelled inside the safety switch. I assumed the top landings were String 1, the bottom String 2.
With both strings connected, SetApp was showing a 19.3 kOhm isolation value at 75.18% of the string length.

How are you celebrating the first summer grid alert of the season? 🙄

MASSIVE outdoor fire NE of the Henday currently burning, reportedly you can see it from downtown. EFRS is on scene.

Will this finally shut up the 15-minute city conspiracy theorists?
