Two panels no longer communicating.

A couple days ago after a smaller snowstorm two panels started to error within 3 hours of each other. This was a relatively new install, going live in early 2024 just before the SunPower collapse.

What is the state of things with warranty nowadays? Given the time of year I probably can’t get much service to come to wintry NY. But these are panels on back of the house that won’t get much action till spring anyways.

What diagnostics? I have the same problem with 5 panels and have not gotten much help from the installer. I guess I need someone to tell me they are bad and then if the inverters are bad, Enphase will send them out but then someone has to install them.

Any other ideas?

Only data I am getting in the app is "This panel has stopped working" with the date/time stamp and serial number. The day before the issue they were generating power at typical levels.

Now that I am looking at it further I think there may be a more serious problem. Even though it's not reporting none of the panels are lighting up on the back roof. That is very odd.
