NEW INSTALLATION: PV SYSTEM WITH BATTERY STORAGE A PV system with a storage system makes the user independent of conventional power generators and rising electricity costs. With the Sunny Boy Storage, this is particularly easy and cost-effective. MODERNIZE: RETROFIT PV SYSTEM WITH BATTERY STORAGE PV system operators require only three additional components—Sunny Boy Storage, battery and Energy Meter—to turn their PV system into a fully-fledged storage system. In this way, they can use even more self-generated solar energy in their own home. EXPAND: ALIGN AN EXISTING PV STORAGE SYSTEM TO INCREASING DEMAND Retrospective system expansion is possible at any time. The PV system and the Sunny Boy Storage system can be expanded independently of each other and flexibly adapted to individual demand.
