Store solar energy
Expand with additional battery power as needed

  • Ideal for grid-connected systems
  • Connect up to three high-voltage batteries
  • Integrated Secure Power Supply function
  • Fully automatic backup function for supplying electricity to the complete home (optional)
  • The integrated service package SMA Smart Connected for automated monitoring of battery inverters

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.
