Southwest Windpower Whisper 200, 24v Wind Turbine w/ Charge Controller

The Whisper 200,1-WH200L-24 by Southwest Windpower is designed for the user who lives in low to moderate wind speed averages (less than 12 mph). The bigger brother to the 100, the 200 features a 10 ft (3.1 m) 3-blade rotor diameter and an 80 sq. ft. swept area that provides the user with greater output at low wind speed averages. The 200 has twice the swept blade area, providing double the potential energy, compared to the 100. It delivers 1000 watts peak power at 28 mph (12.5 m/s), but has a higher output than the 100 at lower wind speeds.

The Whisper 100 and 200 from Southwest Windpower are shipped in a 24-volt configuration, but can easily be changed to 12, 36, or 48 volts by the installer. The included controller is adjustable for use with 12-, 24-, 36- and 48-volt battery systems and the voltage can be adjusted for any battery type. The control can be set to stop the blade from spinning when the battery is fully charged, avoiding wear when power is not needed. The control has a "selectable silent mode" setting that allows the user to select any specific period to automatically turn the wind turbine on or off.

The Whisper 200 does produce more sound than it’s 100 counterpart, but it does produce almost twice the power.

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.

In addition to its patented smooth acting side furling design, the Whisper 200 has a number of new features that make it ideal for any new or existing photovoltaic system:

* 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.

Whisper Controller

Unlike many other small wind systems, the Whisper 200 can be shipped with a controller that 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 200.

The display can be mounted on the controller or up to 1000 feet (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 200.

Wind as easy to use as photovoltaics

The Whisper 200 is designed for even the novice. This turbine installs in just a few hours with no welding, no concrete or cranes. Our engineers designed the work out of installing wind turbines.

Solar and wind work together

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 200 during these periods is essential to keep your batteries charged and your lights on.
