A Wind Generator Review

[Lars_L]

What I know is the Superwind the only wind generator that twists its blades when it begins to come close to over speed. I have a Superwind and it stopped to charge. I took it down and took it apart. I must say that I appreciate what I saw. It was a construction whit quality. Superwind have a 3 phase generator and a rectifier it the generator house. What I dislike was the pure way they have crimped the cable logs on the wires from the generator. Two of them were burned and one of them was broken. That was the reason the generator didn’t charge and it was easy to change. Because of this error the function of the electric brake didn't work, but thanks to the pure mechanical construction of the over spin protection it didn’t over speed.

Double the price. At the point that both wind generators are very very quiet (everyone comments on how quiet our is) the actual Db output comparison is, IMO, splitting hairs... but $1300 vs. $2500 is not.

From what I can tell they are all the same just newer versions?

They cut the speed in half, which reduces the output but also reduces the noise and improves life of the electronics. The product was owned by Southwest Windpower, but in Jan of this year they sold the line to Primus Windpower.

I do realize this was asked about two years ago, however, the "AIR marine" is the predecessor of the Air X.
(just reading through these wind gen threads as my "AIR marine" is on my project list, but more about that later..)

Hi, does anybody have the bearing number of the bearings used in the Air Marine units.
I think the main shafts bearing is a 6203RS but the Yaw bearing is what I need....anybody?

Hi everyone . I'm wondering if anyone has or have used the Apollo 1000w 12v DC, turbine wind generator By Greenergystar ? I found this on Xbey . Looking at the pictures of theirs - v - looks like an Air x ? something by the way it mounts on a pole . The Apollo looks very well bildt, better bearings , better made Roter, anti-vibration, new design 6 blades ,& designed in Canada. I want to make sure i'm not blowing a $1000.oo that, the Hybird charge controller & dump load on junk. I have FOUR 205 AMP Hr diehard 31 AGM batteries.

A compare of two wind generators with each other, one 400 W and one 1000 W.
Some common numbers:
System voltage 12 V
Max allowed power lost in generator 50 W (a guess)
Turbine diameter 1.10 m

Output power 400 W 1000 W
Output current 33.3 A 83.3 A
Measured at wind speed 26 knot 35 knot
Area on wires in winding (a guess) 1.0 mm² 4.0 mm²
Diameter on wires 0.79 mm 2.25 mm

Some conclusions:
The output power is VERY dependent of the wind speed it’s measured at.
It need to be at MUCH more rigid generator for the higher output.


It is also possible to get the higher power by increase the diameter of the turbine, but you still need the heavy generator.
More blades give only a small increase of the power.
A decrease in winding diameter would cause a grater loss of power. It is not possible to increase the power loss very much, the generator will be to warm and burn.

The number looks like theme that SKF use. Have a lock at SKF.com

I'm in the process of buying a 2011 Elan 444. This is a European boat that was sailed across the Atlantic. It was equipped with a DuoGen -- wind and water generator. I'm pretty sure that the original owner installed it because it is recommended for the ARC. It looks like it is in excellent condition (just like the entire boat) and will be checked at survey next month.

Unfortunately, I will not be able to use it when I add davits. Therefore I will be taking it off the boat and selling it. I will be pricing it competitively with a high quality wind generator, e.g. a D400, but I have not figured the price yet; too busy with getting other ducks in line.

Please contact me if you are interested in this unit. The boat is in the Tampa, FL area and I will work with you on transportation if not local.

The reason for posting this now is that you might want to see it before it is taken off the boat in late July (if you happen to live in the area).

Ia that Duo-Gen 12v DC ? And are you selling everything to it wind & water , charge controler ?
I'll be looking to buy something end of July , just not sure what .
I will be heading south from Ohio late August with no particular place in mind
but need generator before i go .

Thanks let me know when you know

It's 12 volts. It was not obvious where the voltage regulator/controller was when I was inspecting the boat, but there must be one. That will go with the generator.
The sale should be complete by the 3rd week in July. But it is a foreign sale so there could be a glitch along the way.

The generator will come off the boat immediately after the sale finalizes so your timing might work.

I will know much more about it by mid-July. Send me your email address and I will keep you informed. Mine is mlibkind (at) bsweet (dot) net.

Ok mlibkind@bsweet.net ,
I'd sure like to see some pictures if you have any of the gen & hydro units
I've got time over a month for sure. I'm still getting my boat ready to live on
and with no room for solar , wind & water is right what i need.

Feel free to email me anytime you have any info

Thanks sailersteve.

I have the D400 and very satisfied with it. There is virtually no sound from it other than the wisper of wind through the blades and only then at 10-15 knts of wind speed. The unit is 8 years old and so far maintenance free.

[jaybird1111]

Aerogen on my boat, came with it, and was in pics of the boat when it was sold some 13 years ago to the prior owner, so I don't know how old this thing is.

I've replaced the bearings recently, two bearings, both same, off the shelf common things. The mechanisms are simple and the Aerogen is extremely quiet (except if the bearings are failing).

Unlike some, if the Aerogen is turning, it's generating. Doesn't turn till at least 8-10 knots across it.

Blades, unlike the bearings, are hard to get/expensive in the US, and I think mine are about UV-done.

Installed a Silent Wind 3 years ago very happy with it whilst not dead silent it certainly is not as noisey as some I have heard.Cost wise it was the highest price of all but I believe you get what you pay for wheight wise 7 kg if my memory serves me correctly
