Photovoltaic inverter separate grounding

Ground fault detection (GFCI) will cause the AC power to trip when it detects unequal currents flowing through the positive (live) and neutral conductors. The fault detection assumes that the current flow is because the electricity has found an unwanted path to the ground. If you accidentally touch a live wire connection, an.
