PV heating
DeltaTherm® PV
The DeltaTherm® PV immersion heater controller detects
excess current, e.g. produced by PV systems, calculates the
power 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.
