kraftBoxx System integration of renewable energies
System integration
of renewable energies
for single-family homes, multi-family buildings, and industrial facilities in the fields of refrigeration, heating, and HVAC, featuring innovative storage systems.
kraftBoxx advanced energy and heat storage solutions based on phase change materials (PCM) and innovative storage systems.
Using PV electricity, our products enable sustainable storage and management of thermal energy.
Trade press
Germany and Italy are joining forces for the future of thermal storage.
kraftBoxx, Axiotherm and the Italian thermal storage pioneer I‑TES are launching a strategic alliance to promote compact PCM storage systems across Europe.
The collaboration combines system integration, materials expertise and innovative product design – and gives I‑TES access to the key markets in the DACH region.
The first systems will be available from 2027 and will complement the existing kraftBoxx portfolio in the 6 to 40 kWh capacity range.

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
