Learn how to troubleshoot and resolve Sungrow Error Code 305 related to grid frequency disturbances.
Error Code 305 indicates a grid frequency disturbance that affects inverter operation. It is crucial to address this issue to ensure system stability.
To prevent grid frequency disturbances, ensure your inverter is properly configured and monitor grid conditions regularly. Consult your utility provider for specific guidelines.
Error 305 is triggered when the inverter detects grid frequency disturbances outside its operational threshold. Inverters are designed to operate within specific frequency limits, typically between 58 Hz and 62 Hz. When the frequency deviates beyond these parameters, the inverter will disconnect from the Utility Grid to prevent damage to its internal components and maintain safety. This protective mechanism is crucial in ensuring that the inverter does not feed unstable power back into the grid.
Upon encountering Error 305, users may observe the inverter's LED indicators flashing in a specific pattern, indicating a fault state. The monitoring app may display alerts related to grid disturbances, and homeowners may notice a sudden drop in energy production, as the inverter ceases operation to protect itself from potential damage.
Always prioritize safety when working with electrical systems. For any troubleshooting or repairs, consult a licensed electrician or certified solar installer to ensure compliance with local codes and safety standards.
To avoid encountering 305 in the future, ensure regular maintenance of the solar system, including periodic inspections of the inverter and grid connection. Proper grounding and wiring practices should be followed during system, and inverter settings should be checked against any updates from the local utility. Additionally, installing surge protection devices can help mitigate the impact of external disturbances.
