Project Background

The Müller family, residing in an energy-efficient house built in 2015 on the outskirts of Munich, Bavaria, Germany, decided to install an energy storage system due to rising electricity prices in Germany (currently as high as €0.42/kWh) and the pressure on power supply from the government's phase-out of nuclear power. The house already had a 15kW rooftop photovoltaic system, but lacked an effective energy management solution.

User Feedback

"This system makes our energy use more intelligent. In winter, when sunlight is insufficient, the system automatically selects the most economical time to purchase electricity. Recently, we even earned extra income by participating in a virtual power plant project and selling electricity to the grid during peak hours."
