The energy storage project was officially opened in June 2015 to supply the first e-charging station located in the National Park Šumava with green power. The park is part of the Bohemian Forest, one of the largest connected forest areas in Central Europe. In order to supply a fleet of electric vehicles, which can be rented by visitors, a green solution was sought, that could also operate grid-independent. In this case the CellCube storage system works in combination with an 11 kWp solar system as well as with a 5 kW wind power plant. The combination of power generation from renewable energy sources with a storage system allows for 100% CO2-free charging of electric vehicles, 24 hours a day, seven days a week.
