a few observations . . . The batteries look like they are hooked together with very small wire. I don't see any fuses or breakers. looks like enough ventilation in the box but I wouldn't keep the rest of the controllers and inverters in there with the batteries, the gasses can be corrosive.

The wires are 6ga and each battery has a fuse. You can see one of them, it's that black, cylinder with the yellow stripe.
Like the guy below observed, these are gel batteries so they don't gas, plus, I have that fan sucking air out and the front of the box is cut at the top to make a big vent gap.[ Parent ]
