Most Common Faults with ABB/Aurora/Power-One Inverters

In short, if your Aurora inverter has an E031 - Int.Error it means a vital internal component has failed. Sadly, this also means that the entire inverter will need to be replaced.

Aurora inverters come with a 5-year warranty. If your system was installed within the last five years, you can send us a photo of the sticker on the side of your inverter (which displays the serial number, WK number and part number) along with a photo of the screen displaying the fault, and we will get straight onto lodging a warranty claim on your behalf. We will then install the new inverter at your premises, and dispose of the faulty one for you.

Please note that it may take up to three weeks for your claim to be processed and for a replacement inverter to arrive.

As this error is almost always an internal component failure, it’s unlikely to be covered by home and contents insurance. To get the ball rolling on your warranty claim or for more information about Aurora E031 internal errors, give our friendly team a call on 1300 73 93 55 or contact us here.

If your Aurora inverter has a W001 – Sun Low fault, it’s an indication that there’s either not enough sunlight hitting your panels or there may be an issue with your panels.
If it’s early in the morning, late in the afternoon, or just a cloudy day, it may not be sunny enough for your system to generate power. However, if there’s plenty of sun around and you’re confident that your panels should be generating power, further investigation into your panels will be required. In this case, we recommend you give our dedicated service department a call on 1300 73 93 55 and book a health check to determine the cause of the fault. As this fault is predominantly caused by internal failure of the unit or external components (such as panels), it is unlikely to be covered by home and contents insurance. Not all is lost though, as Aurora inverters come with a 5-year warranty.
If you’re a Solargain customer and we installed your inverter within the last five years, please contact us ASAP to arrange a health check, so we can determine the cause and help you find a solution. If you aren’t an existing Solargain customer, the fee for an inverter health check will apply to determine the cause of the error. Please take a photo of the sticker on the side of your inverter (which displays the serial number, WK number and part number) along with a photo of the screen displaying the fault, and forward these details to us so we can lodge a warranty claim on your behalf.

About Aurora/ABB solar inverters

Aurora inverters were manufactured in Italy and imported to Australia by ABB. They come with a 5-year warranty and have been installed from 2010 to present.

If your Aurora inverter has developed faults but is still under warranty, Solargain can help you file an insurance claim. You will need to provide a photo of the screen displaying the fault as well as a photo of the sticker located on the side of the unit (which displays the serial, WK and part numbers). Please note, the claim can take up to 3 weeks to process. If your inverter is out of warranty, we can contact the manufacturer for you to see if they will still honour it, which we cannot guarantee.

Some faults may require a site visit, which will be covered if you are a Solargain customer. If not, you will need to pay for a health check so we can properly assess the safety of the installation.

In order to ensure you get the greatest efficiency out of your system, we strongly recommend you monitor it regularly. A major part of this involves checking your inverter. If you have an Aurora inverter, please use the information below to get started!

The electronic display cycles through all available menus automatically, changing screens every five seconds. You can also manually move through the screens by using the up and down buttons (second and third buttons from the right). The third screen displayed will show a figure in the following format: E-tod XXXX Wh. This figure is the amount of kilowatt-hours your solar PV system has produced for the day. Since it’s a daily reading, it’s best to check your production towards the end of the day, before the sun goes down, as it’ll give you the best picture of your overall production.

You can check this figure against the yield estimates provided to you in your Solargain Customer User Manual. This was provided to you in a black handover folder on the day of your solar PV system installation. If you cannot find this manual please call us on 1300 73 93 55 and we will arrange to send a new one to you.

Scrolling down to the fourth screen will reveal the figure: E-tot XXXX. This is the cumulative total of kilowatt-hours produced by your system since it was installed. To work out your average monthly production, simply record the difference between your E-tot figure at the start and end of each month.

For example:

  • E-Total on 1st January is 1100
  • E-Total on 1st February is 1300

January’s Monthly Yield is therefore 200 units (1300 less 1100)
January’s Average Daily Yield is therefore 6.45kwh (200 monthly yield divided by 31 days in January)

Like the E-tod figure, this data can also be compared to the yield estimates in your Solargain Customer User Manual.
 

If you check your inverter first thing in the morning or late in the afternoon (as it’s turning on or shutting down), you may find that the fault light is on. Your inverter might also make clicking sounds. Both of these are normal functions. You should also note that the inverter’s sound increases as it works harder and produces more wattage. Any internal issues with the inverter will be detected by the device and will cause the fault light to be displayed permanently, rather than just during startup and shutdown.

If there is ample sunlight outside and your inverter is displaying the fault light, you should conduct a reset. An instructional guide explaining how to reset your inverter (conduct a manual shutdown) is available on our website here.

If the lights continue to flash orange or red despite resetting your Aurora inverter, then a fault code should appear across the bottom of the screen. Please note down this error message as well as the serial number of your inverter (which can be retrieved from the side of the unit).

Then proceed to call our team on 1300 73 93 55 and we will happily assist you to resolve the issue.

Many Aurora solar inverters are complicated pieces of equipment, so it’s essential they are repaired properly. In most cases, after our specially-trained technicians have visited your property and inspected your inverter, they’ll source replacement parts from the manufacturer, repair the faulty parts themselves or recommend a new system if that isn’t an option.
