More sun for your home
Easy and cost-effective solar energy store

The Sunny Boy Storage is the right solution for all, who want to make their own home through the intermediate storage of solar energy easily and cost-effectively, regardless of the conventional energy suppliers and rising electricity costs. Because for you to stay today and in the future, maximum flexibility.
A clever combination of
For a flexible and cost-effective plant design

With the Sunny Boy Storage customers benefit from significantly reduced System and installation costs and flexible applications. Thanks to the AC-coupling of the battery inverter can be installed at any time and anywhere to install or expand – regardless of whether a PV system is present or not. The Sunny Boy Storage is a real all-round Talent: The used high voltage technology makes it inexpensive and easy. At the same time, he comes with only a few components, because the most important functions are integrated for an intelligent memory usage. The power of the Sunny Boy Storage the ideal choice for more solar in the power supply.

  • For New plants: less installation effort Stock, at any time upgradable and expandable to individual needs
  • Suitable for nearly all PV types of inverters: String inverters, module inverters or power optimizer
  • Can be combined with many types of energy: PV, wind power, CHP
  • Free choice of Li-ion battery (currently Tesla's power wall, additional batteries will follow soon)

  • Cost-efficient AC-coupled battery-inverter on the market
  • 97 % efficiency, allows optimum use of the stored energy
  • Maximum PV yields, in compliance with all applicable regulations for feed-in limitation (e.g., EEG, KfW 275, Zero Export)

  • Quick and easy 1-man Installation thanks to the low weight of only 9 kg
  • Convenient Installation via Smartphone or Tablet through Wi-Fi and intuitive Web-based Interface
  • Everything at a glance through direct involvement in Sunny Portal/Sunny Places
