Tech Tip: Determining the battery capacity in the SMA Sunny Island 6.0H, 8.0H and 5048
A common phenomenon is called "voltage recalibration", where the installer sees the state of charge drop from 60% or 70% down to 20% within a second. Every battery bank has a capacity at a different discharge rate and SMA Australia's Off Grid Solutions Expert shows you how to determine the battery capacity and how to enter the correct value of the estimated state of charge.
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.
