These fault codes help to identify and troubleshoot problems that may occur with the inverter, grid connection, or other components of your solar system. . Solar inverters are the nervous system of any photovoltaic (PV) array, and their failure points represent the highest technical risk for large and mid-sized assets. Unscheduled downtime due to error codes remains the single largest non-financial risk to PV project Internal Rates of Return (IRR). Among the most common problems highlighted by these codes are connectivity issues, temperature spikes, grid disturbances, and incorrect power. . If your SolarEdge inverter isn't producing power or is flashing unusual alerts, the first clue is often in its lights or display. Follow this path to fix it: Advanced Settings > External EPM Set > Fail Safe Set > Change ON to OFF and then press Enter. LimByEPM message occurs even when the setting is turned ON.

If the inverter displays the event numbers 3501, 3601 or 3701, there could be a ground fault. The electrical insulation from the PV system to ground is defective or insufficient. If a ground fault occurs, parts of the system may still be live. Modules with defective module isolation, unshielded wires, defective Power Optimizers, or an inverter internal fault can cause DC current leakage to ground (PE - protective earth). Such a fault is also called. . Most inverter ground fault issues are understandable, diagnosable, and fixable—if you know what to look for.
