Warranty service for Enphase converter

Anyone having issue getting warranty service for their solar panel converter? Enphase claimed 15 years warranty. My system was installed in mid 2010, and one of the converter had failed. It’s the only one reporting low/no voltage for the past 4 weeks. The rest of my 20+ panels and converters are fine.

It look like Enphase is not geared to support home end users. They kept re-directing me to my “installer”. Unfortunately, my installer had gone out of business a few years ago. Yes, live and learn for me. Next time I’ll use a more reputable company.

In any case, Enphase is giving me the run around. Sounds like time to complain to Consumer Protection Agency and local state agency.
