Whisper Wind Generators  The blades on all models, are injection-molded fiber reinforced. All models use a direct drive, brush-less, permanent magnet 3-phase alternator 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 stainless steel or cast aluminum. Models 100 and 200 are preset for 24 volt and are easy to configure to 12, 36 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. 5 year factory warranty. Made in USA.

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.
