System solution for lightning current and surge protection of PV inverters with 2 separate inputs (MPP tracker) pre-assembled in the housing ready for connection. The arresters with fault-resistant Y-circuit with 3 varistors for use according to 0100-712, pluggable with dynamic disconnection device and optical function display are characterized by a low DC protection level < 2.6 kV. The housing including cable gland set, with protection class IP65, made of polycarbonate is UV-resistant and suitable for outdoor use. 10 terminal points up to 6 mm are already pre-installed per protection device. The simple, quick and safe connection of the DC cables via the feed-through terminal blocks enables optimal protection from the electrical inverter. The protection devices are to be selected according to the maximum total open circuit voltage (Uoc) of the PV string. If there is a risk of condensation due to wind, ice, temperature or sun, additional measures may be necessary!
