It needs plenty of wind
The power generation curve is pretty steep and narrow. You'll need almost 20 mph to start producing anything worthwhile. In a 30 mph wind it does it's job very well. In a 40 mph wind power output will drop off considerably. When shorting the output wires, it shuts down very nice and stays shut down, which is important in high wind areas. I had a whisper 200 that disintegrated in a high wind. If you don't have the wind, it's not for you. If you've got the wind, it'll do as advertised.
