Whisper Wind Generators and parts are not currently available

Whisper Wind Generator  The blades are injection-molded fiber reinforced.  Alternator is  direct drive, brush-less, permanent magnet 3-phase for high power and low cost. Unregulated AC power from wind generator is sent to be rectified to DC at the control box which is used for charging batteries. Sealed bearings are permanently lubricated for low maintenance. Frame is cast aluminum. Preset for 24 volt and is easy to configure to 12, 24 or 48 volt.

Includes Charge Control Box and meter display. It shows: Total Kilowatt Hours, Peak Amps (and peak or average wind speed with optional Anemometer) The meter 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.
Start up wind speed is 7-8 mph. Patented side angle governor tilts alternator and blades up and back at an angle for over-speed protection in higher winds.  Made in USA.

Monthly Energy Production
Estimated kilowatt-hours (kwh) per month generated for each model at different average wind speeds (mph).
Local conditions can change energy production. The tower top wind speed is used for calculations. Wind speed is normally stronger with height. Tall towers are recommended.

Guyed Fold-Over Tower Kits

Tilt-up towers can be quickly raised and lowered with a vehicle by one experienced person. No climbing, no welding, no crane. Installation and inspections are done on the ground. The four guy wire anchors are located one-half the tower height away from the hinged base. Components will need to be painted with the color of your choice. Not included is the schedule 40 tower pipe, lifting line, anchors, ground rods, rebar (all of which you can purchase more cheaply locally) and concrete. Shipped freight collect. Tower manuals included with kits or available separately for $12.

There are four types of anchors that are most commonly used with our towers, screw in "Auger" type anchors, hammer driven "duckbill" anchors, cast concrete anchors and expansion bolts (for use only in solid rock). What anchor should be used depends on the soil type that the anchors will be placed in. See the following table for our suggestions.
