Reference project
Apartment-building
An apartment building from the 1960s becomes a showcase example of sustainable living. With a 21.5 kWp PV system and a Voltfang battery storage system, it demonstrates how contemporary, self-sufficient and energy-efficient living can be designed.

“This building gives all residents the opportunity to benefit from the local energy transition. It not only supplies energy for their own use, but also feeds surplus energy into the grid.” – Jan Wollesen
Advantages for the apartment building
Implemented use cases
In this modern residential unit, self consumption has been optimized to increase energy efficiency. Our advanced energy management system ensured that the electricity generated by a 21.5 kWp photovoltaic system was used efficiently for the building’s own requirements. This way, energy costs were reduced and a significant contribution was made to sustainability.
Aim of the project
The aim of the project in the apartment building was to increase energy efficiency, in particular by optimizing self consumption. An energy management system ensures that the electricity generated is used efficiently for the building’s own needs. The house was built to the KfW 40-EE standard for an even more sustainable energy balance.
Our customized solution
The battery storage system was delivered with a net capacity of 58 kWh and an output of 30 kW. The storage unit measures 2100 x 800 x 600 mm and is equipped with suitable inverters to ensure efficient power conversion.
