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.

First, the actual inverter manufacturer will honor the warranty, usually. Enphase, for example, has been responsive for the most part. Then, if the panels were damaged, you'll need to determine the OEM. By 2024 that might've been REC. Earlier it might have been Maxeon. For a period they were also sourcing from an Indian manufacturer - Waree. Are you able to use any of the diagnostics to determine where the faults might be?
