Learn about Sungrow Error Code 041, its meaning, causes, and solutions for leakage current issues.
Error Code 041 indicates an abnormality in the leakage current self-test of the inverter. This could suggest potential safety issues that need to be addressed.
To troubleshoot Error Code 041, check the inverter's grounding and wiring connections. Ensure that all components are properly installed and functioning.
The Sungrow inverter's fault 041 indicates an abnormality detected during a leakage current self-test. This self-test measures the insulation resistance (RISO) of the system's components. If the measured insulation resistance falls below a predetermined threshold, it suggests a potential ground fault. Ground faults can lead to safety hazards including electric shock or fire, prompting the inverter to enter a protective shutdown mode. The inverter continuously monitors for leakage currents to ensure safe operation and compliance with NEC standards.
When error 041 is triggered on a Sungrow inverter, users may observe a flashing LED indicator on the inverter, typically accompanied by an alert in the monitoring app indicating a fault. Additionally, there may be a noticeable drop in energy production, as the inverter may cease operation to protect itself from potential damage.
Always ensure that any troubleshooting or repairs are conducted by a licensed electrician or certified solar installer to maintain safety and compliance with local electrical codes.
To prevent future occurrences of this fault, ensure regular inspections of the solar array and inverter components for signs of wear, moisture, or damage. Implement a routine maintenance schedule that includes insulation resistance testing and ensure that all components are rated appropriately for the system's operating conditions. Additionally, consider installing rodent guards and moisture barriers to protect wiring and junction boxes.
