Whisper 100 Wind Turbine

Turbine features:

Reliable operation by thousands of customers makes Whisper 100 the top selling small wind turbine in its class.

Solar and wind resources often compliment each other. Generally when it is sunny it is calm and when it is cloudy it is windy. This complimentary effect is even greater during seasonal changes. During the winter and spring when the sun is at its least exposure, the wind is at it highest. A Whisper 100 during these periods is essential to keep your batteries charged and your lights on.

Unlike many other small wind systems, the Whisper 100 includes a controller that has a diversion load to ensure quiet safe operation of your wind turbine when the batteries are charged. The display can be mounted on the controller or up to 300 meters away letting you know what is happening. You can even add an anemometer to your controller and now you can measure wind speed and compare it to the output to make sure you are getting the most from your Whisper 100.

A new four bearing spindle for a smoother operation and longer life.
An upgraded Yaw shaft that more efficiently delivers current to your batteries.
New bronze bushing and larger diameter furling pin for smoother furling action.
New castings that allow easy access to the stator for changing voltage.

Exclusive to the Whisper, the side-furling Angle-Governor protects the turbine in high winds by turning the alternator and blades out of the wind, reducing turbine exposure. Unlike other wind turbines that lose as much as 80% of their output when furled, the Angle-Governor allows the Whisper to achieve maximum output in any wind.
