In addition to its patented smooth acting side furling design, the Whisper 200 has a number of new features that make it ideal 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
Whisper Controller
Unlike many other small wind systems, the Whisper 200 ships with a controller that 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.
The 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 200.
Wind as easy to use as photovoltaics
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.
Solar and wind work together
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.
Maximum output in any wind
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.
Whisper Towers
Southwest Windpower offers tower kits that are easy and safe to install. Our kits don't require welding or machining – you just need to obtain pipe material and power wires. We sell anchors separately.
