  Hot water and Heating with photovoltaic

Photovoltaic own consumption up to 100% - with the cheap storage medium water !

With the current surplus of the photovoltaic system, hot water is generated via an intelligent heating element. This is better than the surplus electricity to feed into the grid.

Hot water and heating with photovoltaic!

There are several possibilities:

  • AC-THOR: In addition to heating rods for hot water production, AC-Thor can deliver excess PV power to electric heating mats for wall and underfloor heating systems as well as infrared panels and electric storage convectors and regulate their power continuously.
  • DC-ELWA grey: 6 to 8 PV modules deliver their direct current directly to the heating rod without an inverter (!)  
  • AC-ELWA blue: The PV current, which can not be directly consumed in the house, is used on the heating element for hot water generation.

  • AC-ELWA-E green: In addition, if a battery system is present, the battery is first fully charged, and the excess is sent to the heating element.
