Wind Turbine

Whisper wind generators from Southwest Wind Power come with the EZ-Wire System Center, which provides battery charge control for the wind generator and for a solar array. An LED meter reads battery voltage, wind amps, solar amps and load amps.

All models are now rated and named based on the size of the rotor swept area. For instance, the H20 has 20 square feet of "swept area". This rating method gives a truer picture of the wind generator's power production capability. H indicates 3 blades. (The 3-blade design lasts longer and is more stable in turbulent wind, but is a little less efficient.)

Whispers are shipped in one voltage (indicated by bold in the table below), but can be changed by the user to other indicated voltages. The EZ-Wire system can also control up to 40 amps of solar modules (80 amps for the Whisper 175). Made in U.S.A. 2-year warranty.


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.
