I'm working on putting together my DIY solar energy station. I have all the major parts and the remaining cables are coming.
The one remaining question I have is circuit protection (fuse/breaker/etc) on the battery side of the SCC. In Will's designs (e.g., https://www.mobile-solarpower.com/the-classic-400-watt-rvs-vans-buses.html) he uses a circuit breaker or a fuse block on the positive line between the battery and SCC.
What is the purpose of the circuit protection here? Is it just to protect the wires in the event of massive over-current (e.g., short on the SCC side)? And does it matter what type? Do you need something fast acting (like an ANL fuse), or would a much cheaper MAXI or MIDI fuse or circuit breaker suffice?
