Whisper 500 with Controller 48V

Serious power from a medium size small wind turbine – The Whisper 500 can produce enough energy to power an entire home. Formerly the Whisper 175, the Whisper 500 was completely redesigned in 2004 to work in harsh high wind environments. The Whisper 500 is a two bladed fiberglass reinforced blade and incorporates the patented side furling design that optimizes output at any wind speed. Assuming a 12 mph (5.4 m/s) wind, a Whisper 500 will produce as much as 500 kWh per month. That is enough energy to power the average California home.

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. The display can be mounted on the controller or a 1000 (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 500.

The Whisper 500 is NOT for the novice. Installation of the turbine requires concrete foundations and at times a crane to lift the wind turbine into place.

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 500 during these periods is essential to keep your batteries charged and your lights on.

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.
