Description

The WK -4.4 / 2 wind generator is designed to provide electricity to small and medium-sized objects. On its basis, energy supply complexes are created with an output power of 2-6 kW and an average monthly energy production of 250-500 kW · h.

  It is mainly used for energy supply of autonomous objects, often as part of wind elephant complexes. But it can also be used in places with a network as a backup source and to save network energy.

  Design features of the WK-4.4 / 2 wind generator:

• aeromechanical speed stabilization system

• stop by feathering (aerodynamic brake)

• low-speed generator with direct drive

• reduced design wind speed
