This conversation is quite old, but I'll add my 2 cents worth. Yes, I am a Silentwind customer. All in all I've been quite satisfied with my Spreco Silentwind. I've had it for 3 years now, and one thing I can say is it IS the quietest unit I've ever heard. There's no question about that in my mind. However, I did have the controller fail after about a year and a half. The good news is that even though I bought it in St. Maarten, the repair depot in Florida
replaced the controller without even a sales receipt! That is impressive service!
There is no whoosh sound from the unit as is most common from wind generator
blades, but the unit DOES sing when it gets producing, and when the wind gets higher, say around 25 knots, the singing becomes a 2 part harmony! However, this is not annoying for some reason.
This year I had the boat winterized and I did not adequately protect the head
. It had laid all winter at an angle necessitated by having the boat lifted on a travellift, which exposed the unit to rain into the front, and even though it appears to be closed, water
did get in and washed the bearings. I do not think this would be a situation which would happen to the head
when oriented in a normal horizontal position. Now the bearings are noisier and I need to contact the company to see if there is a way to re-lubricate them. But the unit still works as usual.
I recently read another review in which an owner was bashing the Silentwind for being usable in only a narrow wind band, but I cannot say I have had the same experience. I've not seen the unit have any problems with wind into the 35 knot
range. It WILL automatically shut down for 50 seconds (user adjustable value) when it overheats or puts out "too much" (user adjustable values) current
and/or voltage, but this is correct operation. And it should start turning, but not yet producing, at around 5 knots of wind. Any other questions are welcome.
