Whisper Wind Generator and included Controller are shipped from the factory configured for 24 volt operation unless specially ordered.
200 kWh/month (in 12mph average winds)
The versatile Whisper 200 delivers off-grid energy for applications ranging from remote homes to water pumping. This unit works well in low to moderate winds (3 m/s or above), and with larger blades it produces up to twice the energy of the Whisper 100. A high voltage model is available for transmission over long distances. Ships standard with corrosion resistant finish for coastal or extreme environments.
Whisper wind generators capture the power of nature to provide energy to off-grid areas around the world. Whether you’re creating a hybrid system with wind and solar, powering telecommunications sites or water pumping, Whisper provides dependable energy anywhere there’s consistent wind. Whisper’s patented side-furling design protects the turbine in high winds and continues output at most wind speeds.
In addition to its patented side-furling action, the Whisper 200 Land has other important features that help make it the ideal choice for generating maximum energy at lower wind speeds:

Included with every Whisper is the Southwest Windpower Whisper Controller. Unlike many competitors, the Whisper controller includes a diversion load to ensure quiet safe operation of your wind turbine when the batteries are fully 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 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 200.
Whisper wind generators are designed in America with standard features you may not expect from a small-wind system, including the exclusive side-furling angle. Unlike other wind turbines that lose as much as 80% of their output in high winds, Whisper provides maximum output in most wind speeds.

Here are some tips from the altE staff
I completed the installation of a Whisper 200 system this past July (2006). My electric usage has decreased by an average of 40 to 51% (u=45). I'm very happy with my Whisper 200, but I’m not satisfied as the Connecticut Light & Power has had a few
