    Building inspector & code SECTION R328 ENERGY STORAGE SYSTEMS - Bluetti

    Inspector mentioned fire rated room. My thought was that a fire rated box would be the same thing but I did not run that by the inspector.

    Building inspector & code SECTION R328 ENERGY STORAGE SYSTEMS - Bluetti

    I can put it in my basement or garage but I need it for an office in the main living space. I can put it on my covered porch as long as it is 3' from a window and I may look into doing that. To qualify for those incentives there is income and town location restrictions which I wouldn't meet...

    Is Bluetti AC300 UL Certified?

    This isn't going to answer your question but I ran a the same question past my building inspector and he said because the Bluetti AC200Max was a third party device he had no issue with me using it.

    Break'n the Law! Codes?

    Where I am I inquired about a small off grid system. If you mount a panel on the roof only an electrical permit is needed. For this permit you would have to show that the roof structure could handle the weight of the panel and the components are UL listed, proper wire sizing, etc. If you ground...

    Thanks for your reply, I see what you're saying. This inverter comes with a cig adapter plug for a 12v socket.
