Southwest Windpower Whisper H-40 with Multi Voltage Controller
Whisper H-40 with Multi Voltage Controller
Whisper H-40 Marine Wind Turbine
To get the most out of low to moderate wind speeds (up to 12 mph), the Whisper H80 is the turbine of choice. Featuring a ten-foot (3 m) rotor diameter, the H80 will deliver twice the power in marginal wind areas than the H40. In a 12 mph average wind (5.4 m/s), expect 200 KW/h per month to your batteries.
A high voltage model is available for long wire runs up to 2 miles, and an AC direct drive Water Pumping model connects directly to an electric water pump without the need for batteries.
The bigger brother to the H40, the Whisper H80 features a 10 ft (3.1m) rotor diameter and an 80 sq. ft. swept area that provides the user with greater output at low wind speed averages. The H80 has twice the swept blade area, providing double the potential energy as compared to the H40. The H80 also incorporates a permanent magnet alternator powered with an advanced airfoil, thus capturing the most energy in its class as compared to other competitive wind turbines. At 12 mph average wind speed, the H80 can deliver 6.3 KWH per day.
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 its 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.
