Powering Premium Living: KOSTAL and Dyness Tower Pro Bring Smart Energy Storage to a German Villa

The project combines two KOSTAL inverters with one Dyness Tower Pro TP11 energy storage system, featuring three stacked battery modules and a total rated capacity of 11.52 kWh. By bringing together KOSTAL’s inverter technology and Dyness’s modular battery storage, the installation highlights the value of this compatible solution for modern German households.

Premium Living, Higher Energy Demands

A private sauna and a temperature-controlled swimming pool bring comfort and leisure to everyday life, but they also create considerable electricity demand. Sauna heaters, pool heating and circulation equipment can contribute to household consumption alongside everyday appliances, making efficient energy management particularly important.

For homeowners seeking a more sustainable lifestyle, the challenge is to make better use of available solar power while maintaining the comfort and convenience of their living spaces.

A Coordinated Solution: KOSTAL Inverters Meet Dyness Tower Pro

At the heart of the project is the combination of KOSTAL inverters and Dyness Tower Pro, bringing together inverter technology and battery storage in a coordinated residential energy solution.

As an important local inverter partner in Germany, KOSTAL is a key part of this collaboration. Dyness Tower Pro is compatible with KOSTAL inverter systems, offering homeowners and installers a flexible option for integrating battery storage into a solar installation.

By storing surplus solar energy for use when household demand rises, the combined solution can help increase solar self-consumption and reduce reliance on grid electricity. For a home with energy-intensive amenities, this creates more opportunities to use locally generated renewable energy throughout the day.

Dyness Tower Pro: Flexible Storage for Modern Homes

Designed for residential energy storage, Dyness Tower Pro combines modular construction with high charging and discharging performance to meet a range of household energy needs.

Modular, space-efficient design: Three stacked battery modules form a single Tower Pro TP11 system with 11.52 kWh of rated capacity, providing a compact storage solution for the villa.

High charging and discharging capability: Supporting up to 1C charging and discharging under compatible operating conditions, Tower Pro can help make stored solar energy available when household demand increases. Actual system output also depends on the connected inverter and overall system configuration.

Adaptability to colder conditions: An optional heating function supports charging in temperatures as low as -20°C, helping the system accommodate colder environments.

Safety and durability: IP55 protection, aerosol fire suppression and a rated cycle life of at least 8,000 cycles support long-term residential energy storage.

Together, these features make Tower Pro a practical option for households looking to improve solar energy utilization without compromising their preferred lifestyle.

With an estimated 200–250 equivalent full cycles per year and net savings of €0.20–€0.28 per kWh discharged, the 10.944 kWh of usable storage capacity could deliver approximately €440–€770 in annual electricity cost savings. By making better use of solar energy and reducing reliance on grid electricity, the system can help lower household energy costs while making sustainable, energy-efficient living more accessible.

A Smarter Approach to Sustainable Home Comfort

This project illustrates how KOSTAL and Dyness can bring their respective strengths together to address the energy needs of modern German homes. By combining compatible inverter technology with modular battery storage, the solution offers homeowners greater flexibility in how they store and use solar energy.

For households with energy-intensive amenities such as saunas and heated swimming pools, better use of self-generated electricity can help balance everyday comfort with more responsible energy consumption. For installers and distribution partners, the project also demonstrates the potential of combining an established local inverter brand with Dyness residential storage technology to serve diverse household requirements.

Through continued collaboration with partners such as KOSTAL, Dyness remains committed to developing flexible energy storage solutions that help households make better use of renewable energy and move toward greater energy independence.
