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.
