Learn about GoodWe Error Code 19, its meaning, causes, and solutions for grid frequency issues.
Error Code 19 indicates an abnormal grid frequency setting in the inverter. This can affect the inverter's performance and connection to the grid.
To resolve grid frequency issues, check the inverter settings and ensure they align with local grid requirements. Adjustments may be needed to restore normal operation.
Error 19 is triggered when the inverter detects that the grid frequency is outside of its operational limits. The inverter is designed to operate within a specified frequency range, typically ±5% of the nominal frequency (50Hz or 60Hz). If the frequency exceeds these limits, the inverter's internal safety protocols activate to protect both the device and the electrical system. This can result from grid disturbances, incorrect settings, or component failures that affect the inverter's ability to accurately measure the grid frequency.
Homeowners may observe an error 19 displayed on the inverter's screen or monitoring app, indicating a grid frequency abnormality. This may also be accompanied by a drop in energy production, as the inverter may automatically disconnect from the grid to prevent damage. LED indicators may flash in a specific pattern, typically signaling an operational fault.
Always consult a licensed electrician or certified solar installer when addressing electrical issues or performing maintenance on your solar system.
To avoid encountering error 19 in the future, ensure that the inverter is installed according to local electrical codes and that it is regularly maintained. Periodic inspections of the wiring and connections can help identify potential issues before they lead to faults. Additionally, stay informed about local grid conditions and any maintenance schedules from your utility provider.
