Fronius Ohmpilot heating element controller
The Fronius Ohmpilot is a heating element controller for domestic hot water preparation using surplus PV energy . Its stepless control from 0 to 9 kW allows for the connection of single-phase or three-phase heating elements, efficiently utilizing excess PV energy. This enables you, for example, to heat your domestic hot water from April to October using the surplus energy from your PV system. As a result, the conventional heating system can be switched off during this period.
