In this guide, we will walk you through common Growatt solar inverter error codes and provide simple solutions to get your system back up and running.

Quick Summary

Growatt solar inverters are reliable but can sometimes show error codes. Understanding these codes and knowing how to troubleshoot them can help maintain your solar system’s performance.

Understanding Growatt Solar Inverter Error Codes

Growatt solar inverters come with a digital display that shows various codes to indicate the status of the inverter. These codes can help you identify any potential problems with your system. Some common error codes include:

  • E001: This indicates an internal error in the inverter.
  • E008: This code signifies an issue with the grid, such as a power outage.
  • E011: This code shows up when there is an over-temperature error.

These are just a few examples of the error codes you might encounter. It’s important to refer to your Growatt inverter manual for a complete list of error codes and their meanings.

Troubleshooting Growatt Solar Inverter Error Codes

Once you’ve identified the error code, the next step is troubleshooting. Here are some common issues and their solutions:

  • E001: Try resetting the inverter. If the error persists, it may require solar inverter repairs.
  • E008: Check if there’s a power outage in your area. If the grid power is fine, there might be a problem with the inverter’s grid connection.
  • E011: Ensure the inverter is not exposed to direct sunlight or high temperatures. If it’s properly shaded and ventilated but still showing this error, contact a solar electrician in Melbourne.
