Features MAIN PURPOSE: An arrester protection grounding component that collects static electricity from photovoltaic modules and brackets and introduces it to the ground through copper wire. WORKING PRINCIPLE: When the screw is locked, the spike will pierce the anodized layer of the aluminum rail or other conductive metal layer, forming an airtight electrostatic connection. COMPATIBLE RAIL: The photovoltaic grounding clip is compatible with various aluminum PV guide rails (roof, ground, car shed), C shape steel, U shape steel, H shape slot steel, etc. METAL STRUCTURE: This terminal is assembled from aluminum alloy body and stainless steel screws, metal structure is stable and reliable, wear resistance and oxidation resistance. REPLACEMENT PARTS: Including 5pcs grounding clips, used in solar mounting system, can directly replace old or damaged ones, allows for multiple grounding conduction installation methods.
