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.
I’m an electrical PM so the lack of overcurrent protection jumped out at me, I have to consider overcurrent protection for every single circuit I reason about, it’s mandatory and should be included in this installation.
The image part of your comment was nerd bait so everyone replied to that :P
