I just upgraded the solar system at my family's off-grid cabin. It's incredible how much battery technology has improved over the last 10 years. Everyone is getting tired of me checking the panel to see how many watts we're bringing in. Next project, install a shunt and get a Raspberry Pi talking to it over USB. And then I'll be able to build a Grafana dashboard. :)
Really curious about the difficulty of doing a self install with Solar. I'm moderately handy (built a Sauna from no plans) and confident with electrical. Any gotchas?
