Southwest Wind power 36Volt 900W Whisper Wind Turbine


  • The Whisper 100 is designed to operate in a site with medium to high wind speed averages of 12 mph, 5.4 m/s, and greater.

Years of reliable operation by thousands of customers have made the Whisper 100 the number one selling small wind turbine in its class. With thousands in the field, the Whisper 100 has become the standard for remote homes, telecom sites and rural developing projects for moderate to extreme environments. Assuming a 5.4 m/s average wind, a Whisper 100 will produce 100 KWh per month for batteries.


The Whisper controller and turbine can be quickly field set to 12, 24, or 36 volt configurations to match the system battery bank voltage.


The Whisper 100 provides 100+ kWh per month, 3.4 kWh per day, in a 12 mph average wind. Worried about noise? The Whisper 100 is one of the quietest wind turbines ever tested by the National Renewable Energy Labs.


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


Included with every whisper is our new Whisper Controller. Unlike many of our competitors, the Whisper controller includes a diversion load to ensure quiet safe operation of your wind turbine when the batteries are charged


It installs in minutes and it protects both your wind turbine and battery. The Whisper controller fits easily inside your battery room. Add the optional LCD display and you will instantly receive real time data on the performance of your Whisper 100. The display can be mounted on the controller or a 1000 (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.


The Whisper 100 is designed for even the novice. The Whisper can be installed in just a few hours with no welding, no concrete or cranes. Our engineers designed the work out of installing wind turbines. Now wind is as easy to use as photovoltaics.


Why small wind? 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.


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.
