New member here. I'm planning a solar arrangement for my 4WD Suburban that I use for camping and photography excursions and have just begun acquiring parts. I notice on some 12V system videos that some attach a fuse directly to battery positive terminal, even though the pos cable terminates at a circuit breaker before outputting to the appliances (MPPT, inverter, fuse block, etc.). I plan on using an SOK 12V/100aH LiFePO4 battery connected to a 175A breaker. Do I still need a large fuse at the battery terminal, or is this overkill? If the fuse is needed in addition to the breaker, why? Thanks for any help.
