Thanks for your posting about the Spreco generator! There's virtually no info on these silent gens to be seen save the factory loud pitch. So I'd really appreciate you sharing your experience with us. I have been waiting for someone to give an idea if it is worth its money and lives to the factory promise of: 1. low cut in wind speed, 2. low noise and 3. power generated

Good luck!

I have a Marine Breeze that I just changed the blades on, I bought the silent wind blades and the hub, fits well and easy to convert, but spendy. After putting them on I had to leave boat to work and have not had much time to monitor them in all conditions, but for the 24 hours I was on board they were very quiet and a big improvement. I could not here them, but now I can here a slight hum from the generator when its putting out power. The original blades made a wooshing noise so I couldn,t here the generator background hum. You have to be about 10 feet away to here hum.

Re: Silentwind Wind Generator

How heavy is it? CAn it be mounted on a single 3/4 inch stainless steel strut? I have a Freedom 44 and the mizzen boom protrudes a bit over the transom.

Be glad for the external controller. SW windpowers internal ones are crap. I went through 3 at a high price before I scrapped it and went with a bridge rectifier and no controller.

Orla,

I really like those rubber padded U bolts. Where did you buy them?

Doug,

Thanks for the pictures. There so far has been a negative opinion posted on the internet about Silentwind. Can not recommend Spreco Silentwind Wind Generator - S/V Gudrun V The owner mainly graiped about the charge controller but also mentioned there's no charge in less than 13 knt of wind. Could you please share your experience. It may be light, silent, aesthetically pleasing and of a solid background of German ingeneering but if does not produce current under 15 knts it would be just a nice embelishment and a free ad on a boat's arch.

Also the company does not specify if their controller is MPPT or not. The off/on switch is integrated with the controller but what if one wants to use a different controller and the switch is not separately available (unlike it is with Superwind 350)? Life isn't meant to be easy in the world of green.

Hi,

you see a lot of them here in Grenada - my personal opinion is that this are very quiet units compare to the other ones. Its subjective but there is right now a boat with an X and a one Silentwind side by side - I strongly vote for the Silentwind from a noise point of view. I talked with one owner and he seems very happy with his unit as well.

Still, I stick with my solar - I swear my 420 Watts of panels are as silent as it can get!

The conversion from AC to DC performed by the charge controller is in effect MPPT, unfortunately the additional PVC input is not regenerated and only takes 180watts of panels so I have a separate charge controller for the PVC on our boat. The shorting of all 3 wires to the genset cause it to brake and spin slowly, that said I can't imagine that any 3rd party low voltage AC to DC charge controller wouldn't include a stop circuit.

I'll post a more comprehensive review of our install of the Silentwind shortly.
