PKOM4 & PSOL+ system solution

PKOM4 system solution with renewable energy

As a compact ventilation unit, the patented heat pump combi unit PKOM4 replaces a complete heating/cooling/service water system. The combination with renewable energies such as photovoltaics and an intelligent energy management system like PSOL+ makes the PKOM4 an efficient, cost-effective system solution with which operating costs are reduced to a minimum, thus making it possible to implement a zero-energy building or even a "plus energy" building.

PSOL+ providing for the easy integration of renewable energies


  • Storage battery up to 11 kWh
  • Hybrid inverter with emergency power function up to 10 kW
  • Energy management for system optimization
  • One app/visualization for the whole system solution

Advantages / pro arguments:

  • Pre-assembled / installed overall solution
  • Plug & play – easy, reliable
  • Lower installation/energy costs
  • Everything from one single source – one contact person
  • One app / visualization
  • Independent in the event of power failures – emergency power function
  • High degree of personal energy usage of the photovoltaics system
