SWWP has done a good job with both the Whisper H-500 and their 70 foot tilt-up tower kit. The tower assembled easy with the step by step instructions. ARE has a similar 5" Sch. 40 tilt-up tower for the H-500 that can be as high as 84 feet. My hope is that SWWP will have higher tower available soon. The H500 was assembled easily and went up easily. The controller wired and installed easily.

I have it on a SW5548 inverter. All work very well. Last month produced 150 KWH in our wind zone 2-3 and that was only 3 weeks of operation since for a week it was iced over. Compared to the Skystream located 1 mile away, the H-500 consistently spins and produces usable power when the Skystream does not even turn. So far I'm very happy with the H-500 although a bit noisy when furling. Peak Power for last 30 days: 3700 watts.
