I did the shorting current calculation on that battery in the pic elsewhere in this thread. The fuse was there for decorative purposes only, at those currents everything is a fuse, the one Ththing you really have to hope for is that it will douse fast enough and that there will be no air/fuel or H2/O2 mixture nearby. That's the main reason I built this pack into a little building (underground bunker really) of its own near the house but not so near that it would be a problem if it would break down.

The inverters were housed in the second half of that bunker so as far as the house was concerned nothing changed.

The whole system was capable of producing 11KW, two tandem 5.5KW inverters ganged to produce 240 V for well pumps and other large consumers (welder, plasmacutter).

It worked super good but you really had to keep an eye on the charge level when running big tools, the plasmacutter would drain the battery in about an hour.

But running the plasmacutter was the exception, not the rule so most of the time it was just powering a very low level of loads compared to most houses.

I really miss the system, and the farm it sat on.
