3-PV String Combiner Box. Complete with DC Fuses and DC Isolator
Most of the solar panel strings have to connected in parallel with several PV modules. PV combiner boxes is the safest solution to connect the solar cables of the PV array to your battery charge controller or the inverter. The combiner boxes contain cylindrical string fuses to protect the PV string from high current. The fuses are compulsory all solar arrays with parallel strings. The current Amp rating is easy to calculate, (N-1) x Isc , this will give you the maximum rating of your string fuse. N is the number of parallel strings. Isc is the short circuit current of the solar panel. It is imprerative to use fuses in both positive and negative terminals.
