Features of Surge Protection Devices:- Standard: IEC 61643-11 / EN 61643-11, Type 2, Photovoltaic surge protection, Without Remote signaling contact, Integrated SPD health indicator, Backup Fuse Rating 80A gL/gG, Protecton Level ≤1.5kV.
Due to the combination of three power varistors, the overvoltage protection required for the inverters is implemented on the DC side. On the AC side, the overvoltage protection can be ensured using surge arresters type 2 (5SD7422-/5SD7424-)
