Proven technology
Now Even More Affordable
With the new generation of devices, the tried-and-tested Sunny Island battery inverters are easier and more affordable to install than ever – both in your home and in commercial applications as well as to the utility grid and in off-grid locations.
The Sunny Island has been installed more than 120,000 times worldwide. With the new generation, installers and PV system operators benefit from an even more user-friendly battery inverter.
The Sunny Island 4.4M version is no longer produced by SMA. Technical information, such as operating manuals or datasheets of these versions can still be found in the download area.
