Tech Tip: Diagnosing error code Vac-Bfr/Vac-Srr or Event 801 (Grid Failure)

If the grid voltage goes outside the acceptable range (according to Australia Standards) due to a black-out, a spike, or voltage fluctuations in the utility grid, SMA inverters will quickly disconnect from the grid for safety reasons. SMA Australia's Technical Service Specialist demonstrates how to check the cause of the grid fault in classic and new generation SMA inverters.

The above video forms part of SMA Solar Technology Australia’s series of Training Videos which aim to deliver a better understanding of SMA Inverters and SMA Monitoring equipment for Clean Energy Council accredited photovoltaic installers.
