SMA Sunny Boy Storage 3.7
Sunny Boy Storage 3.7 - A reliable supply at all times
The Sunny Boy Storage 3.7 is a high-performance SMA battery inverter for private homes. Larger storage systems are easy to implement and are flexible to expand with a total of three battery connections.
Store solar energy
Expand with additional battery power as needed
New installation: PV system with battery storage
A storage system makes you independent from conventional power companies and rising energy costs. Thanks to high-voltage technology, storage systems with the Sunny Boy Storage are particularly efficient and easy to install.
Modernize: PV system with battery storage
To use even more self-generated solar energy in the home, an existing PV system can be expanded into a fully fledged storage system with just a few additional components. The operator further reduces the amount of electricity purchased from the grid and minimizes electricity costs.
Expand: Align a storage system with increasing demand
Thanks to multistring technology, up to three high-voltage batteries can be connected to the Sunny Boy Storage anytime. This allows the storage system to be expanded gradually and adapted to individual needs.
Always up and running quickly with modern communications
Reliable electricity supply
Reliable power supply–even in the event of grid failure
