I re-did my first solar install to be more permanent! Everything is now a few inches away from the wall to prevent water seepage, and there's drip loops where there should be drip loops.

In the box is an ESP32 running esphome that talks to the solar controller over modbus to collect metrics on the solar setup itself. (It reports back to @homeassistant.)

I still need to plug the hole in the waterproof box so the wasps don't find a new warm place to live. 😨

Oh. I also need to figure out a better way to do a quick disconnect on the battery for safety than spring clamps, but the spring clamps work for now.

@opsnlops How quick is quick? I use Anderson power poles in various colors for all sorts of DC applications. They disconnect quickly enough for me. I fuse everything so I don't have to grab wires with the insulation melting off in order to effect an emergency disconnect. (Been there, done that, learned to fuse everything.)

@shuttersparks Yeah, something like that could work. I really need to get fuses in-line. This is a 12v system, and it's in a shed that I don't really care about, but I wanna learn how to do things properly. 😅

@opsnlops Yeah. Fuse everything according to the gauge of wire. High current and melting copper wires is not fun. Plus it can start a fire and it smells bad. Hahaha.

Anderson Power Poles are fabulous connectors. I've used them for all DC stuff since 1994. Check out the ham radio standard way of assembling them and you'll be compatible with everything too.
