Whisper 100 Land Wind TurbineThis Product is no longer available

Historical Information presented below:

Whisper, a name with more than 10 years of experience in the field, has been re-engineered and launched under the Southwest Windpower family of wind turbines. The Whisper has an all-new look featuring a cast aluminum frame and smooth, quiet operation of the patented "angle- governor" furling design.

The Whisper 100 Land Wind Turbine is designed to operate in a site with medium to high wind speed averages of 12 mph, 5.4 m/s. and greater. The Whisper 100 provides 100+ kWh per day, in a 12 mph average wind location. The Whisper 100, with its 7 ft (2.1m) rotor diameter and 40 sq. ft. swept area, is rugged enough for extreme environments.

The redesigned Whisper 100 turbine incorporates a permanent magnet brushless alternator, which combined with Whisper's high efficiency composite airfoil blade design, delivers 900 watts peak power at 28 mph (12.5 m/s).

Applications - Stand-alone or hybrid Telecommunications applications, remote home and ranch applications

New 12/24/36/48 volt Controller - The Whisper 100 comes with the new multi voltage charge controller that offers greater reliability and superior control for battery charging. The price of the Whisper 100 turbine includes the multi voltage controller.

New Design Features

    Whisper 100 Land Wind Generator
  • The 100 was redesigned in the fall of 1999
  • Stronger cast aluminum housing
  • New Angle-Governor provides higher maintained output while furling
  • Improved current carrying capacity
  • Sealed yaw bearings
  • Temperature tested from -30F to over 90F
  • Temperature tested from ?40?F (-40?C) to 110?F (43?C)
  • Increased heat transfer for better cooling
  • Blades: 3 injection-molded, fiber reinforced

Patented Angle-Governor 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.
