Learn how to troubleshoot and resolve Growatt error code 118 initialization failure effectively.
Error code 118 typically indicates an initialization failure due to incorrect settings or hardware issues. Checking connections and settings can help resolve this.
To reset your Growatt 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 Growatt inverter triggers Error 118 during the initialization phase, primarily due to electrical anomalies that prevent it from properly establishing a connection with the solar array or the utility grid. This may involve insufficient DC voltage from the array, which can be caused by shading or soiling. Additionally, ground fault detection mechanisms may activate if the inverter detects irregularities in the grounding system or wiring, which can also lead to safety concerns. The inverter is designed to monitor grid frequency and voltage; if these parameters exceed operational limits, the inverter will halt its operation to protect itself and the connected systems.
Upon encountering a Growatt Error 118, users may observe the inverter's LED indicators flashing in a specific pattern, accompanied by alerts in the monitoring app indicating an initialization failure. The system's production may drop significantly or halt altogether, leading to an unexpected loss of energy generation.
Always consult a licensed electrician or certified solar installer when troubleshooting or working on electrical components to ensure safety and compliance with local codes.
To prevent future occurrences of Error 118, ensure regular maintenance of the solar array, including cleaning and inspection of all connections. Periodically check the grounding system for integrity and verify that the inverter's firmware is up to date. Monitoring the performance of the system through the app can help identify issues before they lead to fault codes.
