Description
With the SUNNY BOY STORAGE multistring battery inverter, for the first time, up to three different high-voltage batteries can be connected to one battery inverter. To connect larger batteries, three DC inputs can also be connected in parallel. The Sunny Boy Storage has integrated emergency power, which can be switched manually. Furthermore, it can even take over the entire electricity supply of the three line conductors via the optional automatic transfer unit. Thanks to proven AC coupling, the Sunny Boy Storage is ideally suited to new and retrofitted systems. The integrated webserver, with a smart inverter screen and installation wizard or via the SMA 360° App, enables fast and easy commissioning. Energy flows in the household are fully transparent thanks to the direct connection to Sunny Portal and SMA Energy App.
