Frequently asked questions (FAQ).

Formerly the Whisper H80, the Whisper 200 has been updated for 2005 with new features and added flexibility for your renewable energy system. Now, any Whisper 200 can have its voltage changed, 12-48V DC, within a few minutes in the field. The Whisper 200 is designed to operate in a site with low to medium speed averages of 8 mph, 3.6 m/s, and greater. The 200 provides 200+ kWh per month, 3.4 kWh per day, in a 12 mph average wind. The Whisper 200 does produce more noise than it’s 100 counterpart, but it does produce almost twice the power. Click on the link above for a copy of the noise data report.

In addition to its patented smooth acting side furling design, the Whisper 200 has a number of new features that make it idea for any new or existing photovotaic system.

A new four bearing spindle for a smoother operation and longer life
An upgraded Yaw shaft that more efficiently delivers current to your batteries
New bronze bushing and larger diameter furling pin for smoother furling action
New castings that allow easy access to the stator for changing voltage

Included with every whisper is our new Whisper Controller. Unlike many of our competitors, the Whisper controller includes a diversion load to ensure quiet safe operation of your wind turbine when the batteries are charged.

It installs in minutes and it protects both your wind turbine and battery. The Whisper controller fits easily inside your battery room. Add the optional LCD display and you will instantly receive real time data on the performance of your Whisper 200 wind generator. The display can be mounted on the controller, or 1000 ft (300 meters) away, letting you know what is happening. You can even add an anemometer to your controller so you can measure wind speed, and compare it to the output to make sure you are getting the most from your Whisper 200.The Whisper 200 is designed for even the novice. The Whisper can be installed in just a few hours with no welding, no concrete or cranes. Our engineers designed the work out of installing wind turbines. Now wind is as easy to use as photovoltaics.

Why small wind? Solar and wind resources often compliment each other. Generally when it is sunny it is calm and when it is cloudy it is windy. This complimentary effect is even greater during seasonal changes. During the winter and spring when the sun is at its least exposure, the wind is at it highest. A Whisper 200 during these periods is essential to keep your batteries charged and your lights on.

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.
