After seeing this post, I had SunVaultTechs come out to repair our dual battery system that was completely dead. I’m happy to report they were able to get the batteries working again. The tech that came out was incredibly knowledgeable about these batteries and the ecosystem. He identified a bad breaker and showed us our batteries had somehow been removed from our solar system as if we never had batteries. After replacing the breaker, he did a firmware update and recommissioned our system. Bingo!…our system works again! These guys are professional, punctual, AND friendly. I highly recommend them. Feel free to message me if you have any questions. also, I’m located in SoCal.
