The strings are connected in a string box, which is installed between the PV array and the SunMaster CS inverter. The high DC loads and currents require top quality and safe components. The varistors in the StringMaster reduce the risk of lightning strike damage to the PV array, cables and inverter.
Choose breaking capacity: In > Isc x 1.56. Example: Isc = 7.95 A --> 7.95 x 1.56 = 12.4 --> next higher rating --> choose 15 A fuse.
StringMaster fuses are marked with the ‘gPV’ and ‘’ symbols, showing compliance with IEC60269-6. Use of non-compliant fuses is prohibited as it may lead to severe damage or even fire.
