Is your Aurora inverter displaying a W001 – Sun Low error message?

What does a W001 – Sun Low fault mean?

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.


How do I resolve a W001 fault?

If it’s early in the morning, late in the afternoon, or if it’s a cloudy day, it may not be sunny enough for your system to generate power. However, if there’s plenty of sun around, further investigation into your panels will be required. In this case, we recommend you give Solargain a call and book a health check to determine the cause of the fault.


Is a W001 fault covered under warranty or on my home and contents insurance?

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.

Aurora inverters come with a five-year warranty. If you’re a Solargain customer and we installed your inverter within the last five years, please contact us urgently to arrange resolution. 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) and a photo of the screen displaying the fault, and forward these details to us so we can lodge a warranty claim on your behalf.

For more information about Aurora W001 faults or to book your system in for an inverter health check, please call Solargain on 1300 73 93 55.
