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 an 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. In other words, the inverter has an issue where it isn’t measuring voltage correctly. In our experience, we’ve found that E031 errors are caused by issues with the relays inside the inverter. Unfortunately, the E031 Error is an internal error which means your inverter will need 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 we do have some good news for you – it is covered under warranty. Warranty coverage is, however, dependant on the inverter still being within the warranty period. ABB / Power-One solar inverters came with a standard 5-year warranty so subsequently for a valid warranty claim it would’ve needed to have been installed with the last 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 it should still be covered under warranty. If so please contact the manufacturer directly. Power-One & ABB solar inverter warranties are covered by a company called FIMER.
FIMER, who honour the Power-One / ABB warranties, can be contacted on 1800 769 663.
If your ABB / Power-One Aurora inverter with the Int. Error E031 is out of the 5-year warranty we recommend replacing it with a quality new unit. You can try and have the faulty internal relays repaired however in our experience even after being repaired it doesn’t take long for another problem to develop. If that happens you’ll have to throw more money at the thing, so it makes sense to bite the bullet and get a new inverter with a full warranty from the start. For this purpose, we recommend Fronius solar power inverters as they have a long 10-year parts warranty and are a perfect replacement for the ABB / Power-One Aurora inverters.

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!
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.
