ABB Aurora Power-One InverterThe ABB Aurora Power-One range of solar inverters include a variety of different sized solar inverters to suit nearly any on grid application and like every range of solar inverter they have a number of fault codes which can in certain situations be displayed.

The following is a list of error codes, messages, causes and solutions from ABB Aurora Power-One Inverter user manual. The following list contains the error and alarm messages that the ABB Aurora Power-One inverters may display along with the procedures for solving possible problems and some appropriate trouble shooting tips. If you require any further assistance please fill out the following form and we’ll help if we can.

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.
