Increasing the auxiliary power supply of PV systems

The principle of Power to Heat

The basic principle is to use the surplus electricity from the PV system to generate heat via an electric screw-in heating element - independently of the heat generator. This is then stored in the thermal stratified storage tank.

Inverter and power meter

An inverter first converts the direct current of the PV module into alternating current. A power meter then analyzes the PV system's power flows. It transmits information about surplus power to the AC-THOR. In this way, only the available energy is used for heat generation without feeding back into the grid. This maximizes the PV system's own consumption.

Power Manager and screw-in heaters

The Power Manager uses the surplus energy from the photovoltaic system to supply the infinitely variable screw-in heating element. This allows up to 18 kW of electrical energy to be converted into usable heat. The screw-in heater is available in various output levels from 2 to 9 kW. So you can find the right solution for your needs.

Stratified charging unit

In addition to the screw-in heater, a stratified charging device can be installed in the Sailer storage tank. This layers the electrically generated heat directly into the usable storage tank area.

The advantages of power-to-heat systems:

• Environmentally friendly storage: generation of heat without producing CO2 or other environmentally harmful substances
• Self-sufficiency: Power-to-Heat increases independence from the existing energy system
• Simple retrofitting: A power-to-heat system can be integrated into both new and existing systems
• Own use of electricity: Good alternative to unprofitable feed-in to the public grid
• Optional stratification: When using a stratified charging device for electric screw-in heating elements, the electrically generated heat can be efficiently stratified directly into the usable storage area
