Friends: When I design a lead-acid battery system I decide if I need over-current protection right at the battery or not. My logic is: if the leads are short, don’t go through a wall and are well protected, I can rely on OCPD in the BOS cabinets. If any of these criteria is a no I put appropriately rated class T fuses right at the battery.
I’m thinking that since BMS devices have over-current protection baked-in, fusing at the battery would not be necessary for BMS equipped batteries in any case. Do you agree with that premise? William Miller Miller Solar.com 805-438-5600 www.millersolar.com
