This assembly consists of nickel-plated aluminum grounding terminals, stainless steel barbed washers, aluminum sliding nuts, and stainless steel screws/bolts/nuts. The package includes 5 sets of cable clamps/grounding terminals (with barbed washers, sliding nuts, and washers), M8*20 hex bolts and M8*25 socket head cap screws, and 5 spare M8 hex nuts. The solar photovoltaic lightning protection grounding terminal assembly collects static electricity from photovoltaic modules and mounting brackets and conducts it to the lightning protection grounding components via grounding copper wire. The upgraded grounding terminal features adjustable mounting holes and spare parts, making it compatible with more installation scenarios and supporting multiple grounding methods. Rugged, durable, and corrosion-resistant, it is suitable for lightning protection and grounding applications in solar photovoltaic systems, compatible with various aluminum photovoltaic rails (roof/ground/shed), C-shaped/U-shaped steel, H-channel steel, and other mounting brackets. After the screws are tightened, the spikes on the grounding barb washers will pierce the anodized layer on the surface of the aluminum alloy rail or other conductive metal structure, causing the metal structure to form an electrostatic connection and conducting the static electricity on the photovoltaic modules and mounting brackets to the grounding copper wire, and finally to the ground.
