How to Choose

String fuses matter most when several PV strings are connected in parallel: if one string develops a fault, the others can push current back into it, and a fuse on each string stops that. Fuses also make fault-finding easier, because a blown fuse shows which string has the problem. This premium kit combines those fuses with surge protection and breakers. Choose the AC MCB rating, 32A, 40A or 63A, to suit your inverter’s output current.
