Batteries & equipment mounted INDOORS - Code?

Have read a few threads about people mounting batteries & equipment indoors but haven't seen it addressed specifically from the angle of code & permitting.

We're in the planning stages of an off-grid new build and I am planning on putting all the equipment in a utility room inside the main living space, but I want to make sure I don't run afoul any building code for permitting purposes.

Batteries are Dakota Lithium 48v with built-in BMS, and the inverter/PV charger will likely be a Sol-Ark 12k. I know the Sol-Ark is rated for outside installation but I'd rather not.

There will not be an attached garage so that is not an option.

Anyone have a permitted system with everything inside?

Your most reliable answer will be from whomever will be inspecting your system to see what they say.

Yes I know I'm going to need to talk to the county; I'm just trying to gather input from others who may have done something similar so I'm going into it as informed as possible. ?
