Product Description
Solar Surge Protector PV SPD 1500V DC Lightning Arrestor Solar Surge Protection Device
Product Introduction
DKG-20 is a kind of module DC power surge protection device(short for SPD), which is installed in the front end equipment of photovoltaic DC power distribution system. It is designed as module with 35mm din rail mounting. It has working indication window in each line. When working indication window turns red, the SPD breaks down. With temperature control circuit breaker and built-in over current protective circuit, this modular SPD can automatically release to avoid fire danger when it breaks down.The optional remote alarm function is convenient for remote monitoring and automated management. The main module and the base are replaceable. It can be used for lightning protection of +-PE.

Installation Instruction
1) DKG-20 photovoltaic DC power surge protective device shall be installed in the front end of DC power distribution equipment. It is installed in the output bus of PV combiner box, or the input terminal of DC power distribution cabinet/box and grid tie inverter. It is in parallel connection with the power grid (Please pay attention to the power line and the ground wire);
2) When installation, please use Kevin Connection Mode as soon as possible, that is, shuck off the Insulating Layer from the Middle of Power Distribution Power Line, then put the Power Line in the relative connection terminal and tighten the screw;
3) When using the General Parallel Connection Mode, the conductor sectional area of power SPD should be in the range from 4mm2 to 35mm2 (the specific conductor size, please choose according to the size of distribution power line). The length of connecting line should be less than 0.5 meter.
4) The sectional area of grounding connection line should be larger than the power connection line, and the distance from the grounding wire to grounding assembly row should be less than 1 meter.
