Heat pump with photovoltaics

Renewable energies intelligently combined

Connecting electricity, heating and transport

Expanding renewable energy is one of the objectives of European energy policy. Electricity generated from renewable sources can be used for heat pumps and electric vehicles, among other things.

Sector coupling connects electricity, heating and transport. This allows renewable energy to be used across different applications. When heat pumps are combined with photovoltaics, part of the electricity needed to run the heat pump can be supplied by the PV system.

Advantages for your customers

The KeEnergy control system for your heat pump

As a manufacturer of heat pump systems, you can offer your customers decisive added value in the implementation of intelligent energy management systems by using the KeEnergy heating control system.

Cost savings

As electricity for heat pumps gets closer and closer to the price of normal electricity for households, the consumption of cheaper, self-generated electricity is becoming more and more attractive.

Combining a heat pump with photovoltaics can increase the savings from self-generated and consumed electricity.

Optimisation of self-consumption

As the feed-in remuneration for private photovoltaic systems continues to decrease, the implementation of decentralised energy supply and the coupling of electricity, heat supply and transport is becoming an increasingly interesting option. With suitable controls, this can increase the share of self-generated electricity used on site.

Easy integration

into your heat pump

For those who want a precise overview

This is how the KEBA heating control system KeEnergy is integrated into your heat pump:

Our innovative heating control system has a Modbus TCP interface. This means that it can be integrated into an energy management system that supplies the heat pump with information about the excess power fed into the grid. Alternatively, this information is passed on to the heat pump via an S0 meter. The Smart Grid Ready interface can also be used to control the heat pump with PV energy.

Modbus TCP interface

The energy manager determines the surplus power supplied to the grid and transmits it via Modbus TCP to the heat pump control. As soon as the PV surplus power exceeds a configured limit value, the heat pump is switched on and operated with PV power.

The KeEnergy heating control system regulates the power consumption of the variable-speed heat pump exactly to the power specification of the energy manager.

S0 interface

upstream or downstream of the heat pump

The feed-in meter with the S0 interface determines the surplus power supplied to the grid and passes it on to the heat pump control. As soon as the PV surplus power exceeds a configured limit value, the heat pump is switched on and operated with PV power.
The KeEnergy heating control system regulates the power consumption of the variable-speed heat pump exactly to the power specification of the energy manager.

Smart Grid Ready interface

As soon as the power of the PV inverter exceeds a configurable value, a potential-free relay contact is closed in the inverter. This controls the Smart Grid Ready input on the heat pump control and the heat pump is operated with PV power.
