Learn about the flashing red and green lights on your Sungrow inverter and how to troubleshoot it effectively.
A flashing red and green light on a Sungrow inverter typically indicates a fault or error condition. It is essential to check the inverter's manual for specific error codes and troubleshooting steps.
To reset your Sungrow inverter, turn off the inverter and disconnect it from the power source. Wait for a few minutes before reconnecting and turning it back on.
The alternating red and green lights typically indicate a fault condition that the inverter has detected. This could be a result of ground fault detection, which occurs when the insulation resistance of the array falls below acceptable levels, potentially leading to unsafe conditions. The inverter may also monitor grid parameters such as voltage and frequency; deviations from acceptable limits can trigger protective measures. Moreover, communication failures between the inverter and monitoring systems can cause erroneous fault indications, leading to operational interruptions.
The Sungrow inverter exhibits a flashing red and green LED pattern, alternating rapidly. Users may also notice alerts on the monitoring app indicating a fault condition. Additionally, there may be a significant drop in energy production, with the inverter displaying a low output or shutting down entirely.
Always consult a licensed electrician or certified solar installer when troubleshooting or repairing solar equipment to ensure compliance with local codes and safety standards.
To avoid this issue in the future, conduct regular maintenance checks on the solar array and inverter. Inspect wiring and connections for wear or damage, and ensure that all components are properly grounded. Keep the inverter's firmware updated and perform periodic insulation resistance testing to catch potential issues early.
