Solar PV Inverter Lightning Arrester
Grounding is the most fundamental technique for protection against lightning damage. You can't stop a lightning surge, but you can give it a direct path to ground that bypasses your valuable equipment and safely discharges the surge into the earth. An electrical path to ground will constantly discharge static. The weakest aspect of many installations is the connection to the earth itself. After all, you can't just bolt a wire to the planet! Instead, you must bury or hammer a rod of conductive, noncorrosive metal (generally copper) into the ground and make sure most of its surface area. Array wiring should use minimum lengths of wire tucked into the metal framework. Positive and negative wires should be of equal length and be run. For building wiring, the NEC requiresone side of a DC power system to be connected—or “bonded”—to ground. The AC portion of such a.
