Power to Heat System Storage

Überschüsse effizent speichern im kraftBoxx Hybridspeicher

All advantages at a glance

  • Utilize total PV surplus through stepless power modulation
  • Use additional latent heat capacity
  • 10 times higher performance compared to conventional Latent storages
  • 2 – 3 times the storage capacity of a water reservoir
  • 10 times cheaper than a comparable battery storage system
  • Capacity 30 kWh, 50 kWh and 60 kWh

Heat, electricity, and water
The PV-Heat system storage tank for heat pumps, gas, pellet, wood, and PV heating systems, with capacities ranging from 500 L to 1,500 L.

  • Ready for solar thermal and PV loading through external loading assemblies

System integration of renewable energies with the kraftBoxx

Bring your system up to date with the latest energy technology

All advantages at a glance

  • Increase storage capacity by 3-4 times with the same volume; easy retrofitting also possible.
  • Reduction of storage volume by 3-4 times with the same capacity, ideal for limited space conditions.
  • Increase service life – you benefit twice! – Peak shifting and extended run times.
  • Reduction of operating costs – reduce power peaks ( = connected load ) ( peak cutting / peak shifting ), use favorable “night electricity tariffs” and own production.
  • Simplified process control – by transforming the temperature peaks to phase change temperature and thus constant injection and withdrawal temperature. An integration as a thermal switch.
  • Higher efficiency – increase of COP (coefficient of performance) and reduction of heat losses due to constant temperature level (operating costs up to minus 40% !), use of smaller cooling/heating generators possible.
