Freedom you generate yourself.
From consuming energy to generating it.
A building used to be a place where energy arrives and is consumed. It can just as well be the place where it is generated.
Freigeist means having more say over your own energy. COR.set generates heat and your own power, especially in winter when electricity is expensive. COR.stor stores your own energy for later. The COR Platform connects everything into one system, so you generate and use more yourself and have more control over your energy costs.
- The building generates energy.
- It stores energy.
- It uses energy when it is needed.
Three products. One system.

What could your home save?
The calculator simulates your building for a full year in 15-minute steps, using the weather data for your region: heating, electricity demand, photovoltaics and storage. You see the result straight away, and can also download it as a PDF.

Energy when it matters most.
In winter, heat demand rises while photovoltaics deliver less. That is exactly when the heat and power plant in COR.set generates up to 2.2 kW of your own power while heating. Heat demand becomes a source of your own winter power, and you need to buy in less, or even none, of that expensive winter electricity.

A completed installation, commissioned in 2026: three COR.stor units and three inverters, run together as one system.

Your energy is your freedom.
Generate more yourself. Store more yourself. Use more yourself. That way you decide for yourself how you use your energy — when you use it and how little you need to buy in.
