Hi all - I have 2x Pylontech US5000 batteries in parallel, each with their own set of cables (as the cables are rated at 120a). It seems to be a very common mistake that people use the supplied cable to connect 1x positive and 1x negative to the inverter with batteries in parallel, but with 2x batteries there would be a potential 250a flowing through cables which are only rated at 120a max. It seems a bit worrying how many people have this setup (look on YouTube).
I plan to connect each battery cable to a 100a fuse on the positive wires before connecting to a bus bar, which will then be on a 250a between itself and the inverter.
I have a Blue Sea 5502 250A T fuse in place, but I was just wondering what people use on the battery cables for protection? Do you prefer a t fuse or something like a switched fuse unit? I assume a fuse unit means the cables can be connected directly without the need for a copper cable lug?
Many thanks
