Wind turbine for home and small businesses
Wind turbine for home: Up to 25KW
Viking VS: The domestic wind turbine
Variable speed wind turbine with a rated power of 10 to 25kW
This variable speed household wind turbine is based on its proven and reliable predecessor, the Viking 25. First and foremost, it retains all the great features of the Viking 25, but the Viking VS has a more efficient performance and is more flexible. The domestic wind turbine can be adapted to the conditions required by its location and always complies with the applicable regulations for household wind turbines.
Viking VS' predecessor - Viking 25, was introduced in 2009. It has since been tested with the largest number of turbines in operation in Denmark at the time, making it the best tested wind turbine for home in its class. Since then, we have further developed the turbine based on extensive and real data, of which Viking VS is the result.
To ensure a long lifetime of the turbine, larger safety factors and more conservative calculations on various components have been used at strategic locations compared to the very large megawatt turbines and certain new types of household wind turbines. The turbine will therefore most likely, in most locations, have a lifetime exceeding 20-25 years.

Easy and inexpensive installation and service
There are great cost reductions to get on the assembly and installation of the Viking VS small wind turbine. There is no need for a crane to hoist the turbine. A simple winch can do it - and you are placed on the ground while working with the wind turbine.
This makes service and maintenance of the Viking VS simple and cost-effective. The turbine has to be serviced once a year according to legislation, and the wind turbine can then be lowered and raised with an electric winch. This ensures a low-cost service.
The Viking small wind turbine is 100% functional Danish design.
The Viking Wind turbine is 100% Danish design. With its three blades, it is as aesthetically pleasing as the big megawatt wind turbines
Type
Viking VS optimizes the production at different wind speeds / Tip brakes keep the turbine from running out of control.
Tower
Viking VS is manufactured with a tilt tower for easier installation and maintenance.
Active Yaw
The wind turbine's yaw mechanism turns the wind turbine's rotor upwind. (Wind turbine yaw is used to regulate the position of the blades to the direction of the wind.)
Brake
3 independent brakes for greater safety (Inverter, Electromechanical fail-safe and Tip Brake)
Viking VS wind turbine for home
Is a variable speed household wind turbine based on its proven and reliable predecessor, the Viking 25. First and foremost, all the great features of the Viking 25 are retained, but Viking VS has a more efficient performance and is more flexible. This is because it can be adapted to the conditions required by its location.
Viking VS is designed to meet international standards for domestic wind turbines and comes with a 5-year warranty on all components in Denmark.
To ensure a long lifetime of the turbine, higher safety factors and more conservative calculations on various components have been used in strategic locations compared to large megawatt turbines and some new types of residential wind turbines. The turbine will therefore most likely, in most locations, have a lifetime exceeding 20-25 years.

Flexible and efficient domestic wind turbine
Viking VS is flexible and adaptable, which makes the turbine very efficient. The technical explanation is that the turbine is also speed-regulated in addition to being stall-regulated. So it's not only the wind conditions but also technical calculations that control the rotation speed of the blades. This gives greater control over the turbine, which means that wind conditions can be better utilized.
This also means that the private wind turbine can be adapted to both a location on the west coast and a location further inland, even if the wind conditions are very different. In other words, the home wind turbine utilizes the conditions that its location offers.
