Maximum Efficiency: A Single-Family House with system openness

With a 10 kWp photovoltaic system, a KOSTAL Plenticore Plus inverter, a battery storage system from BYD, and the Photovoltaic Power Manager AC•THOR from my-PV, this single-family house demonstrates how maximum benefit can be obtained from self-generated PV electricity through system openness and compatible partners.

Christoph R., a homeowner from Upper Austria, sought an efficient way to utilize renewable energy for the hot water supply of his single-family house. After the installation of a 10 kWp photovoltaic system and a 5 kWh battery storage system from BYD, it quickly became apparent that surplus electricity – which existed not only in summer but also during months with weaker yield – should be optimally utilized. Thanks to the system openness of my-PV and compatible partners, the integration was seamless - and not associated with additional investments. The necessary surplus information that the AC•THOR receives for heat preparation does not come from a my-PV WiFi meter, but it evaluates the signal from the KOSTAL Smart Energy Meter and prioritizes the BYD battery.

The challenge was to effectively use surplus electricity for hot water preparation without unnecessarily drawing power from the grid. This goal was achieved through intelligent control options and precise coordination of the components. Even during sunny days, surplus electricity is optimally utilized before a minimal remainder is fed into the public grid.

For Christoph R., the decision to invest in photovoltaic heat with my-PV was a clear investment in the future. Not only from an ecological perspective but also from an economic standpoint, utilizing self-generated PV electricity offers clear advantages. With a well-thought-out installation and easy integration into the existing system, the path to increased energy efficiency was a convincing step forward.

How exactly the project was implemented? This is detailed in our reference description.
