Learn how to systematically inspect an inverter that frequently trips on an earth leakage alarm, covering areas such as insulation resistance, PV array, AC side, internal faults, grounding system, environmental conditions, firmware, and event log analysis. . In wet weather, "leakage current faults" are more likely to occur than "PV insulation faults", and leakage current protection equipment is more commonly triggered which will cause the inverter to shut down. A likely cause is that the inverter is disconnected from the grid, entering the protection. . Over time, I have observed that regular maintenance and thorough fault analysis are essential to prevent downtime and ensure long-term reliability. Such a fault is also called an isolation fault. Insulation Resistance Test insulation resistance of all cables (AC and. . Unplug all the strings on the input side of the solar inverter, and then connect them one by one. Modules with defective module isolation,unshielded wires,defective Power Optimizers,or an inverter internal fault can cause DC curre t leakage to ground(PE - protective earth).
