Silentwind wind generator thoughts
I'm zeroing in on a replacement wind generator for our old Air-X, and have come up with the Spreco Silentwind as a top contender. I've read all that has been said here on CF regarding the Silentwind, as well as the other threads about windgens. But since the Silentwind is fairly new on the scene, I'd love to hear from those who've got some experience with them.

Factors I'm balancing are:

- Quality and durability; it's gotta last.
- Output; especially across the 10 to 20 knot range
- Noise level; quieter the better.
- Ease of installation; I would like to use our existing 2" mast.
- Expandability; potential to add solar to the controller system.
- Cost; I have some money now, but won't when we leave in 1 1/2 years.

BTW, others I'm still considering are: KISS, Superwind 350, D400 and Airmaax.

No one running a Silentwind? How about an Airmaax?

Hi Mike,
I've been running a Silentwind for two years now. I got it through eMarine. Output is good, maybe a bit lower than advertised but it does run with just a puff of air. At 15-20k it produces about 12-14 amps. It is very quiet. Other factors: Easy install and assembly, all other components seem to be in great shape (the blue logo is fading) break works very well and the unit has held up in 45+ wind, unbraked, my bad.
Now the bad news. After about 1 year the front bearings began to fail. I shipped it back to eMarine and they replaced it. Great! One year later, same problem/symptoms. It was like pulling teeth to get Silentwind to respond. Finally, eMarine stepped up and sent me a bearing set. Bad news, Peerless bearings, made in China. Nothing but bad press online. Good news, NSK makes bearings that will fit. I hope to see the difference come October 2015! It is a shame that manufactures will cut corners on components, NSK are about twice as much, but everyone wants the stuff cheap. Our fault. Good luck with your search, sorry this reply is late.

Re: Silentwind wind generator thoughts
Wish you had been able to chime in last year windnrock. I purchased a SilentWind and have run with it two seasons now. So far it has worked flawlessly. I'm cruising seasonally though (although moving into full-time) so perhaps I've not put enough hours on it yet. I'll pay special attention to the bearings. So far so good. It's performed pretty much to spec, and it is pretty quiet.
