New Inverter needed?
My girlfriend’s mom has a 15yr old system and she said that the inverter will shut off, she resets it, and then it shuts off not long after again. I did residential solar for about 2 years with Sunpower but we mostly installed AC solar systems and this is DC so I’m not sure if this is something I should take a crack at. I’ve done panel upgrades and other electrical work pertaining to solar so I feel comfortable replacing the inverter if that’s what’s needed. I have a multimeter and tools for an install and I’m aware of the hazards working near electricity. I haven’t worked in the residential solar field for about 2 years now so I just want some opinions on what might be wrong and if this seems like a DIY project. Thanks for any advice!
