Your home energy system is like a puzzle—and the Leaflet HEMS intelligently puts all the pieces together. Let's take a closer look at two top features of the Energy Manager: dynamic tariffs and grid service.
Dynamic electricity rates are like the weather.
Supply and demand: When demand for electricity is high (for example, during a hot summer day when many people are using air conditioners), the price rises. Conversely, when demand is low (for example, at night when most people are asleep), the price may fall.
Generation costs: The costs of generating electricity can vary depending on the energy source. Renewable energies such as wind and solar often have lower production costs when they are available. This can lead to lower electricity prices. Conventional energies such as coal and gas can be more expensive and lead to higher prices when they are needed.
The good thing about Leaflet HEMS is that it takes dynamic electricity prices into account when they are low. And it still taps into your own PV electricity from the roof when there is enough available. One thing is certain: the energy management system ensures the lowest possible costs.
Grid-friendly control directs energy flows.
Grid serviceability according to Section 14a of the German Energy Industry Act (EnWG) may sound dry as dust, but it is an important part of the energy transition. In short, to protect the power grid from overload, grid operators can temporarily limit the output of controllable consumption devices if necessary. This is done by commands from a higher authority, the "control room." However, this control will only be necessary in absolute emergencies.
This means that if a large number of wall boxes, heat pumps, or storage units want to draw power from the grid at the same time, the supply can be limited. This is simply to prevent the power grid from becoming overloaded—while still ensuring that all consumers continue to receive a fixed minimum amount of power.
The Leaflet HEMS secures the entitlement to the statutory minimum benefit and displays any applicable regulations transparently in the app.
It's a kind of magic: one HEMS for all important functions.
Why we are combining all of this into one device: This creates a genuine economic incentive for private individuals to contribute to the energy transition. It is manufacturer-independent and does not require a long-term subscription to a specific system, contract, or tariff.
Installation companies of all sizes now have access to sought-after technologies such as dynamic tariffs and grid services in one package. This allows them to remain competitive with large corporations.
The ecological balance of Leaflet HEMS speaks for itself: a household without Leaflet HEMS would have to plant 1,290 trees to achieve the same potential CO2 savings.
