Up until this point, I've basically just been following instructions and "over-building" whenever in question.
But I'm curious, if a system has 2 parallel strings and you're pulling 100 amps on the total battery, would the cable between each battery string and the bus bar read as 50 amps? I'd never do this, but hypothetically if you wanted to fuse each string as low as possible (forgetting that the cable itself could handle much more), how would one determine the fuse size you could get away with?
