Learn how to troubleshoot and fix a general internal error in Goodwe inverters effectively.
Common causes include firmware issues, wiring problems, or component failures. Regular maintenance can help prevent these errors.
To reset your Goodwe inverter, turn off the inverter, wait for a few minutes, and then turn it back on. This can clear temporary errors.
Inverters are designed to convert DC electricity generated by the solar array into AC electricity for use in the home or for export to the utility grid. When an internal error occurs, it often indicates that the inverter has detected an anomaly that could pose a risk to the system's safety or performance. For example, ground fault detection systems monitor insulation resistance (RISO) to prevent electrical shocks or fires. If the RISO falls below acceptable thresholds, the inverter will trigger a fault to protect itself and the connected array. Similarly, variations in grid frequency can cause the inverter to shut down to avoid damage, as it must operate within strict voltage and frequency limits dictated by the utility grid.
Homeowners may notice that the inverter's LED indicator is flashing red or displaying an error message on the monitoring app. Additionally, there may be a significant drop in energy production, which can be observed through the system's performance data. Alerts regarding internal errors could also appear in the monitoring system, indicating that the inverter is not functioning optimally.
Always prioritize safety when working with electrical systems. It is highly recommended to consult a licensed electrician or certified solar installer for any troubleshooting or repairs to ensure compliance with safety standards and regulations.
To avoid future internal inverter errors, ensure regular maintenance of the solar array, including cleaning panels and inspecting for physical damage. Implement periodic insulation resistance testing and verify that the inverter's cooling system is functioning efficiently. Keeping firmware updated and monitoring grid conditions can also help preemptively identify issues before they trigger faults.
