System solution for the lightning current and overvoltage protection of PV inverters with separate input (MPP tracker) ready in the housing pre-assembled. The arrester with error-resistant Y-circuit with 3 varistors for use according to VDE 0100-712, pluggable with dynamic Disconnection device disconnects and visual function display are characterised by a low DC protection level< 3.0 kV. The housing including Cable screwing set, with protection class IP66, made of polycarbonate is UV-resistant and suitable for outdoor use. Per protective device are already pre-installed 3 clamping points up to 16 mm². The simple, fast and secure connection of the DC cable via the continuity series terminal enables an optimum protection against the electrical inverter. The protective devices are in accordance with the maximum sum of open-circuit voltage (uoc) of the PV-string. In the event of danger, condensation by wind, ice, temperature or sun are necessary additional measures required!
