Learn about the clicking sound and flashing green light in GoodWe Inverters and how to troubleshoot it effectively.
A clicking sound in an inverter may indicate a fault in the system or a protective mechanism activating. It's essential to check the inverter's status and connections.
A flashing green light typically indicates that the inverter is operating normally but may also signal a temporary issue. Review the user manual for specific meanings.
The clicking sound from the inverter is often a result of internal relay operations, which may be triggered by safety mechanisms in response to abnormal conditions. The inverter continuously monitors insulation resistance (RISO), which is critical for identifying ground faults. If the RISO measurement falls below a safe threshold, the inverter will engage protective actions, including audible alerts and LED signaling. Moreover, overvoltage conditions or grid frequency limits can also activate these protective features, as the inverter is designed to safeguard both itself and the connected array from damage.
Upon observing a GoodWe inverter, you may notice a repetitive clicking sound accompanied by a flashing green LED light. The LED pattern may vary, but typically it indicates an operational alert or fault condition. Additionally, monitoring apps may show production drops or alerts related to inverter performance.
For any troubleshooting or repairs involving electrical components, it is crucial to consult a licensed electrician or certified solar installer to ensure safety and compliance with local codes.
Regularly inspect the inverter and array connections to ensure integrity and proper insulation. Schedule periodic maintenance checks, including insulation resistance testing and visual inspections of the wiring and junction boxes. Keeping the firmware updated can also prevent software-related issues.
