SG Ready (Smart Grid Ready)

Effectively control heat pumps with smart SG Ready relays

SG Ready certification for heat pumps can be sustainably optimized with intelligent IP relays. Relays contribute to the effective implementation of the SG Ready functionality of heat pumps and enable efficient energy use throughout the smart home or industrial plant.

The IP relays Expert Net Control 2302 and 2304 from GUDE support home and industrial owners in controlling their heat pump systems.

What are SG Ready certified heat pumps?

SG Ready (Smart Grid Ready) is a certification in Germany, Austria and Switzerland for heat pumps that shows that they can be integrated into an intelligent power grid (smart grid). Digital interfaces allow smart grids to control the heat pumps flexibly, e.g. during periods of high electricity production from renewable resources or low grid load. This helps to stabilize the power grid and balance load peaks.

How does a smart grid operate with heat pumps and how can this be linked to photovoltaic systems?

Heat pumps are widely used as heating and hot water systems in German buildings. Around 356,000 heat pumps were sold in 2023. The digital link to the smart grid allows heat pump operation to be optimized automatically. For example, the heat pump can be activated at times of low electricity prices or high electricity production from renewable resources such as wind or solar power. In phases of high grid load, on the other hand, when many consumers require electricity, the heat pump can reduce its output or temporarily cease operation. This helps to stabilize the grid load and avoid overloads.

Many heat pumps are also linked to solar systems. These can work together via the smart grid interface, for example to tap excess energy from the solar system and use it for heating. With this technology, the hot water system can also be heated with solar energy if the consumer uses it.

SG Ready heat pumps in terms of energy efficiency. How does it benefit me as a home or industrial owner?

SG Ready heat pumps play an important role in the energy transition as they can efficiently use excess solar or wind power. In combination with solar systems, they can use excess electricity directly for heating or hot water. This saves costs and reduces the load on the electricity grid.

For homeowners, SG Ready offers the opportunity to take advantage of cheaper electricity rates through flexible operation. Grid operators benefit from more stable grid capacity consumption, as heat pumps can act as controllable consumers.

Future developments could improve its integration with intelligent industrial and smart home systems to further optimize a building’s overall energy consumption.

The Expert Net Control 2302 and 2304 are compatible with systems such as 50Hz Energy Manager and Solar Manager. These energy management systems make the relays a flexible solution for heat pump set-ups with SG Ready functionality.

Conclusion regarding SG Ready

Smart relays enable efficient control of SG Ready certified heat pumps and help to optimize energy consumption. By integrating into smart grids, heat pumps can respond flexibly to grid conditions and use excess renewable energy, resulting in cost savings and a more stable grid load.

Relays such as the Expert Net Control 2302 and 2304 provide a reliable interface between heat pumps and energy management systems, supporting efficient control that benefits both consumers and grid operators. Future developments could further integrate this technology into smart home technology and further increase energy efficiency in industrial and domestic environments.
