Whisper 500

The Whisper 500 ships complete with a controller and diversion load, ensuring quiet, safe operation of your wind turbine when the batteries are charged. The controller installs in minutes and it protects both your wind turbine and battery and easily fits inside your battery room.

Add the optional LCD display to instantly monitor real-time data on the performance of your Whisper 500. The display can be mounted on the controller or up to 1000 feet (300 meters) away, so you can monitor performance in the comfort of your home. You can even add an anemometer feed to compare wind speed with turbine output to make sure you are getting the most from your Whisper 500.
