Effective use of surplus PV power

Solar-Log™ in combination with a heat pump

Combining photovoltaic with heat pumps offers another potential way to optimize the consumption of self-produced power. The basic idea is to use surplus PV power to run the heat pumps. Here, depending on how the heat pump is connected to the Solar-Log™, a release signal or the surplus is reported to the heat pumps.

Key advantages for plant owners

  • A building can be used as a heat buffer storage.
  • Energy efficient buildings (i.e. energy-efficient building shell) are especially well suited for this.
  • The target temperature in the rooms is then maintained by the IDM heat pumps depending on the selected comfort mode.
