Learn how to troubleshoot and resolve Solis Error Code 1029 related to export limit protection.
Error Code 1029 indicates that the inverter has reached its export limit protection threshold, preventing further energy export.
You can check the export limit settings through the inverter's user interface or monitoring software to ensure they are configured correctly.
Error 1029 signifies that the inverter has detected an export limit condition, which is a protective measure designed to prevent the system from sending excess energy back to the Utility Grid. This can occur when the inverter’s output exceeds the configured export limit, often due to high solar irradiance or incorrect settings. The inverter continuously monitors parameters such as grid voltage and frequency, and if these exceed preset thresholds, it will trigger this fault to safeguard both the inverter and the grid.
Upon encountering Error 1029 on the Solis RHI inverter, users typically observe a red LED indicator blinking or a notification in the monitoring app indicating an export limit protection error. Additionally, there may be a noticeable drop in energy production, which is reflected in the daily or real-time output data.
Always ensure that a licensed electrician or certified solar installer addresses inverter issues. Working on electrical equipment can be hazardous and should only be performed by qualified licensed technicians.
To avoid encountering Error 1029 in the future, regularly check and adjust the export limit settings based on seasonal changes in solar irradiance. Periodic maintenance of the array, including cleaning and inspection for shading, can also help maintain optimal performance. Additionally, ensure that the inverter firmware is updated to reflect any changes in grid requirements or inverter capabilities.
