kraftBoxx System integration of renewable energies
powerReducer– Increase your own power consumption:
Self-consumption set 3kW
- 3-phase energy meter
- Power electronics for connection
to a 1 phase standard 3 kW heating element, such as heating rod or eTherm C3
PV-Heat
with powerReducer+ energyCounter
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

Fast solution for my projects - very happy to do it again

The PCM elements make the kraftBoxx storage units very compact, which saves us a lot of space when space is tight in existing buildings.
In times of climate change and high energy prices, efficient storage systems make an important contribution to the energy transition.

The team from kraftBoxx GmbH has been able to help us with our projects several times and always offers great support.

With heatStixx, I was able to retrofit my existing storage tank and can significantly reduce my fuel consumption.
