Very nice. It get's my like. I think I'll stick with my part solar Chia farming though. (a mans gotta eat) Keep this sort of content coming, it's grate.
I'm wondering why you have the bulb there. It's function seems to be to just waste solar power. You have plenty of metering to tell you what is happening.
It's temporary. There's a situation: battery voltage is brought up slowly, miner switches on, sun shines strongly, miner is not ready to mine, battery voltage rises, BMS takes the battery out of circuit, system is unstable. This requires a charge control relay which I have on order.
It would be interesting to know the self consumption of the balancer ? With such a small battery pack do you get more storage with top balancing and turning off the balancer, or leaving it running ?
