tubra®-eTherm S
Power to heat
The tubra®-eTherm S detects surplus electricity from PV systems, determines the available power and passes it on to an electric heater. In this way, excess electricity is converted directly into thermal energy and stored. Power electronics for stepless control of 3 kW electric heating elements for buffer and drinking water tanks.
- increasing the self-consumption of the PV system
- priority for household electricity
- applicable on all potable water and buffer storage tanks with 6/4 socket to accommodate an electric heating rod
- energy storage in hot water tanks with significantly higher storage capacities than in batteries
- optimal for retrofitting to existing storage tanks
- fast power modulation 0 – 3000 W
- exact, fast measurement of the excess current
