powerReducer – Increase your own power consumption:
Self-consumption set 3kW
- 3-phase energy meter
- Power electronics for connecting
to a 1-phase standard 3 kW heating element, such as a heating rod or eTherm C3
PV-Heat
with powerReducer + energieZähler
increase self-consumption:
The photothermal solar system for the use and storage of excess PV electricity in the form of heat.
- Stepless conversion of excess electricity to heat
- 3 phase measurement of the injected energy
- The storage process increases the proportion of self
- consumed energy increased – grid relief takes place
- Profitability can be increased
- Increase of own demand by use of the not in the household itself
- required energy in the form of heat
- Easy installation without disconnecting the main electrical line
