He did and end run around saftey, and just put the whole system in a shed, which in any real emergency situation , dramaticaly reduces risk to life and property. Also each battery bank is.air gapped , which will significantly reduce any fire from spreading to adjacent banks. The system looks well made, and has 8 years up time. I live off grid and am useing lead acid batteries, but would like to switch to sodium.

The banks are "air gapped" by just a few cm, are all interconnected with excellent heat conductors (the bus bars), is insulated with flammable plastic, and sit on a flammable shelf in a flammable shed.

There is no fire safety there. Let's just hope the shed is very far from a house, fences, trees, bushes, or anything else that could catch fire and close any "air gaps" and cause harm.

Edit, digging in, each single cell is fused, very nice work, and exceptionaly safe to run. As good as anything built, anywhere.

That is an astounding claim, and requires astounding proof.

I'm game, but first, would you be so kind as to give some indication of your practical or theoretical understanding of the subject of off grid, grid tie or remote/small grid or even portable power systems. I will restate that the homebuilt system under discussion is remarkable in just how simple and effectivly it has been designed to reduce risk to the lowest possible levels, ie: idivdual cell fuseing, coupled with very low power/volume density in a physicaly removed electrical building, means that the conditions for a fire are very low, the chance if that fire spreading to the whole bank are very low, and any possible, small, slowly burning fire then escaping the electrical build is low, and the chance of that small fire then injuring any unsuspecting indivuals is the exceptionaly low. The only astounding part is that the guy who designed and built it isn't bieng consulted in formalising his method for wider adoption.
