Will Prowse is the best resource I've found. He gets a little technical sometimes. And he is passionate about solar power so he sometimes talks a bit fast.
But he covers a lot of important topics about both vehicle and residential solar.
Wish I'd found his channel before I started on my power system. Would've changed a few things.
Thankfully he gives my charger unit a thumbs up when he reviewed it. But with what I've learned on his channel I realized I'm a bit painted in a corner with it.
Next solar system I build is definitely going to be 24v or 48v. Thinner cables and better solar panel compatibility.
