DeltaTherm® PV
The DeltaTherm® PV immersion heater controller detects excess current, e.g. produced by PV systems, calculates the energy available and redirects it to an electric heater. Thus, excess PV current can be directly converted into thermal energy and stored. By means of a Datalogger or the Communication module, the self-generated current can be visualised via the www.VBus.net Internet portal.
incl. sensor module, 3 current sensors and 1 Pt1000 sensor (FRP6)
