> No short-circuit protection? That’s the first thing I noticed too. You can buy a 277VAC/60VDC 7A DIN rail miniature circuit breaker that can handle 7,500 amps of fault current for $20 [0] there’s no excuse other than ignorance for the lack of overcurrent protection. I only know how to use a calculator to figure out AC fault current but that should be enough to handle a solar panel. It does mention an optional thermal switch and optional thermal fuse, my sauna stove definitely has a thermal switch and I’d include one if I was building this thing too.
