  • GFI Tripped on 3 M-215s

    I'm about to post 2 threads about 2 different systems...

    So I'm looking to purchase a home that has 21 panels connected with M-215s. I asked the owner to get access to the Enphase data. To his surprise, 3 of the microinvertors were not producing. Looking in the events, 3 of these units are error out as "GFI Tripped". They all tripped at different times, but they've not been producing for over a year. They are all the top panels on the ridgeline of the roof. My suspicion is that there was some water that got where it wasn't supposed to, and when I reset the flag on the Envoy, everything will come back to normal. The company that installed the system is hours away, and wants essentially $300 plus work time to fix this. I can likely find a local company to deal with it, but I want to take a stab at it first.

    Anyone else experienced this and have suggestions?
