ABB / Power One Aurora Int Error E031 – What to do
Have you just walked past your ABB or Power One solar inverter and been greeted with a Int. Error E031 fault message on the screen?
According to the ABB / Power One Aurora operators manual Int. Error E031 indicates a wrong voltage measure or a voltage misreading by the inverter; so the inverter has an issue where it isn’t measuring voltage correctly. Unfortunately this is an internal error which will require the inverter to be replaced.
Int. Error E031 Fault – Covered by ABB / Power One Aurora Warranty
Thankfully if your ABB or Power One Aurora inverter is showing the Int. Error E031 it will be covered under warranty by the manufacturer if the inverter is still within the warranty period. ABB / Power One solar inverters have a standard warranty of 5 years.
ABB / Power One Aurora Inverter Int. Error E031 Fault – What To Do
If your ABB / Power One Aurora inverter was installed within the last 5 years then the best thing to do is get in touch with the manufacturer, ABB, directly to make a warranty claim.
ABB can be contacted on 1800 222 435.
If your ABB / Power One Aurora inverter with the Int. Error E031 is out of the 5 year warranty the best thing to do would be to replace it with a quality new unit. We recommend the Fronius solar power inverters with a long 10 year parts warranty as a perfect replacement for the ABB / Power One Aurora inverters.

The EO31 indicates one of the 4 AC relays has a fault
, most commonly just one of the four pins has lost it’s solder on the printed circuit board. This is a steel pin from the main steel relay frame & didn’t receive proper heat at time of manufacture, an overlooked manufacturing fault. The relay is a Zettler AZ2150W-1AE-12DEFT. I bought five of these from a Malaysian co. for $3 postage free to Tasmania. I have now repaired 3 of these in inverters within my family with this fault. Only 1 relay had to be replaced as the steel pin was burned away, the others just required better soldering with harder solder & adequate heat. From start to finish takes about half an hour. For half an hour’s labour and at most, a $1 for a new Zettler relay why would you scrap a whole inverter? I low of a local solar installer who has a bundle of these ‘dud’ in inverters stacked in his workshop having been replaced mostly under warranty. What a nonsense! The Zettler manufacturer ought to advise that special attention to correct soldering practice should be applied to the relay main frame pin, a quick dab of solder as applied to the other circuit board component pins is insufficient.

Hi Roger, well done for rectifying the ABB / Power-One Aurora E031 error yourself! I have personally repaired quite a few of these E031 faults however I have found over time that the other relays tend to fail as well and quite often the damage to the Printed Circuit Board (PCB) from the relay pins overheating causes the PCB to be damaged beyond repair. Due to these factors, as a company we cannot recommend repairing the inverter as we are not prepared to provide a warranty on this work. Thanks for sharing your success with us!
