DeltaTherm® PHM
The DeltaTherm® PHM is the ideal solution for using excess PV current for the control of different loads. Heat pumps, electric immersion heaters, and charging stations for electric vehicles can be controlled as needed. All the while household power has absolute priority. Each load can also be supplied with mains current on a time-controlled basis. Furthermore, the DeltaTherm® PHM measures the electric loads at the energy meter which can be visualized via VBus.net.
incl. measuring unit, 3 current sensors and 3 Pt1000 sensors (FRP6)
