The application video explains the benefits and versatility of AC•THOR.

Hot water heating and space heating with solar power

AC•THOR is a 0 - 3 kW linearly controlled photovoltaic power manager for hot water, electric heat sources and optional space heating.

Simple & efficient: AC•THOR controls electrical heat sources depending on the availability of PV energy and heat demand. And that for both hot water, as well as for space heating. It ensures your personal living comfort fully automatically. In a residential building that is built or renovated according to current energy standards, AC•THOR replaces conventional, water-based building installations. Missing residual energy can be obtained from the public grid.

Of course, AC•THOR can also be integrated into conventional, water-based systems such as buffer storages. Its flexibility leaves nothing to be desired. Thanks to the built-in touch display, it can be operated without any additional devices at any time and it is easy to install.

AC•THOR in combination with my-PV Power Meter

In combination with my-PV Power Meter, AC•THOR uses excess energy from your photovoltaic system to supply electrical heat sources such as immersion heaters, electric heating mats or infrared panels linearly with power. This ensures optimal energy utilization.

AC•THOR in combination with battery storage

In combination with compatible batteries, AC•THOR, like AC ELWA-E, performs a hybrid storage function. Not only the hot water, but also the building mass can be used as storage.

Thus, even with larger PV systems, excess PV energy is optimally used. Optimal priority regulation between battery and heat storage is guaranteed.

AC•THOR in combination with Smart Home

Thanks to its flexible control, the AC•THOR also communicates with energy management systems. As an alternative to my-PV Power Meter, the excess information can also be received from these sources. Thus there are no limits for the integration into individual home controls. Data can be visualized in the Smart Home System.
