All the information in the tables above has been taken from the ABB Aurora Power-One Inverter user manual’s Troubleshooting section.  Should you follow the troubleshooting steps above but are still having issues with your ABB solar inverter, check if it’s still within the 5 year warranty period. If it is we recommend contacting the equipment installer or supplier.

If your ABB Aurora Power-One Inverter is outside the warranty period or your original installation company is no longer trading we suggest that you contact a local professional solar power expert. Enter your details into the following form and we’ll see if we can help.
