EDIT: Discovered the problem was the DC disconnect got filled with water somehow.
June 4th, my SolarEdge 7600 inverter began reporting Error 25, (2x19), Isolation Fault and stopped producing AC power. Diagnostics on the inverter LCD shows:
R Iso[KOhm]: 156.8
[------------------------*]
DC+ DC-
100.0%
where resistance between DC and ground is reported as 156kOhm when it needs to be over 600. A couple days later it showed 86kOhm and today it shows 28kOhm.
I sent all this info to my solar installer (including a link to pictures and videos) who contacted SolarEdge who somehow diagnosed it as a communication board fault and sent out a comm board via the slowest 7-10 business day shipping method available. Is it even conceivable that a comm board could cause an isolation fault or am I doomed to wait however many days for them to send someone out only to find it does nothing to fix the problem, followed by another 7-10 business days for another part?
The SolarEdge web portal continues to work and shows it's generating no power, but it does show the panels providing DC volts and other live info, so it doesn't seem like there's anything wrong with the comm board at all. Only odd thing is the portal always shows "Inverter Status: Starting" and "Last Isolation Value [KOhm]: 0".
Is there anything I can do to speed this up? Is it worth contacting SolarEdge directly?
