Community Power

As a sonnen customer, you are at the heart of the energy eco-system. Your sonnenBatteries, in partnership with sonnenFlat or sonnenConnect can collectively contribute to a more stable electricity grid through a virtual power plant (VPP).

The sonnen VPP connects batteries digitally to form a large virtual battery to create a virtual power plant, which works to stabilise fluctuations in the electricity grid and place downward pressure on energy prices. Only by connecting many decentralised home batteries into one VPP, are we able to take the place of traditional intensive power plants.

By connecting to the sonnen VPP, you will be helping to compensate for fluctuations in the grid. Depending on the demand, electricity can occasionally be temporarily stored in the battery or released back into the grid. Your sonnenBatterie can make an important contribution to the clean energy transition in times of need.
