Quick Summary

Goodwe Solar Inverters are reliable and efficient but may sometimes show error codes. Understanding these codes is key to effective troubleshooting and ensuring the longevity of your solar system.

Understanding Goodwe Solar Inverter Error Codes

Goodwe Solar Inverters come with a built-in display that shows different error codes when there’s a problem with the system. These codes are designed to help you identify the issue and take appropriate action. It’s important to note that some issues can be resolved by the user, while others may require professional solar inverter repairs.

The most common error codes include “Error 117” which indicates an issue with the inverter’s internal temperature, “Error 102” which points to a problem with the grid frequency, and “Error 103” which signifies a grid voltage issue. Each of these issues requires a different approach to resolution.

How to Troubleshoot Goodwe Solar Inverter Error Codes

Once you’ve identified the error code on your Goodwe Solar Inverter, the next step is troubleshooting. For instance, if you encounter “Error 117”, it’s advisable to check the inverter’s ventilation and ensure it’s not exposed to direct sunlight. If the problem persists, it might be time to consider solar inverter replacement.

For “Error 102” and “Error 103”, it’s best to consult with a solar electrician in Melbourne. These errors typically indicate issues with the grid, which require professional expertise to resolve. Always remember that safety should be your top priority when dealing with electrical systems.
