Good day,
We used to install SolarBridge microinverters when we first started. You know the deal."we've improved what Enphase started".and they were great - up until Sunpower bought it to meet market demand for an AC-module, then a reemergent Enphase bought it from a cash-strapped Sunpower, and promptly threw the whole kit and caboodle into the trash heap never to be seen again. But now we have some 25-year warrantied MIs not working, and the associated "Home Power Manager" monitoring device failed which means by-module monitoring is gone. These were AC-modules from ET Solar and that seemingly went bankrupt at some point, too and reemerged as a new ET Solar. A coupled of questions: Other than the seemingly infinite permutation of module strings it would take to narrow down inop MIs, does anyone have techniques or tips on how to identify individual faulty MIs? Did anybody else install SolarBridge and if so, any feedback on warranty support?
