Independent: Heartbeat enables optimised self-consumption and thus increases your degree of self-sufficiency.

Connected: Your components are combined into a smart overall system in which energy production and consumption are coordinated.

Intelligent: Heartbeat intelligently controls your consumption and uses your electricity in a way that gives you the greatest economic advantage. You use up to 10% of your solar electricity yourself - that's about 100 Euro p.a..

Heartbeat is available in a bundle with our green electricity contract - it obtains clean electricity when it is cheap on the energy market.

Flexible: If there is a lot of wind energy available, the electricity price on the electricity exchange drops. This is exactly when Heartbeat controls your devices that are supplied with green electricity from the grid, such as the wallbox of your electric car or your heat pump.

Dynamic: Heartbeat optimises the procurement of your required residual electricity on the energy market. You benefit directly from the low electricity prices.

With the Mobility Bonus in the Heartbeat Package, you secure free electricity worth 300 Euro (per e-car) per year. We market your CO2 savings via the GHG quota!

GHG quota: The greenhouse gas reduction quota regulates the reduction of climate-damaging gases. CO2 savings from e-cars are made tradable by the Federal Environment Agency. The saved CO2 emissions are sold to companies that sell fossil fuels so that they share in the costs of environmental pollution.

No hassle: We organise the certification and market it to companies in the petroleum industry. The proceeds flow back to you - in the form of free green electricity.
