Understanding ABB Solar Inverter Error Codes

ABB solar inverters display error codes on their LCD screens to alert users of potential issues. These codes are designed to help you identify the problem quickly and take appropriate action. However, understanding what these codes mean can be confusing without a reference guide.

For instance, error code 0008 indicates an issue with the inverter’s internal temperature, while code 0014 suggests a problem with the DC/AC converter. Familiarising yourself with these codes can save you time and stress when troubleshooting your system.

Troubleshooting Common ABB Solar Inverter Issues

Several common issues can occur with your ABB solar inverter. These include no power output, inconsistent power output, and error codes. Here’s how to troubleshoot these issues:

  • No power output: Check the AC and DC isolators to ensure they’re turned on. If they are and there’s still no power, it’s time to call in the professionals.
  • Inconsistent power output: This could be due to shading, dirty solar panels, or a faulty inverter. Consider cleaning solar panels or seeking professional help.
  • Error codes: Refer to your ABB solar inverter manual or the section above for guidance on what these codes mean and how to address them.
