I want to buy a wind turbine. 500-2000w

Yes i know they dont produce much. yes I know they dont produce as much as solar does. Yes I know i dont make money on it.. But they "could" produce some in the night and would be fun to try out.



Criteria:

Should be able to hook onto my current 48V system.
Need to start at low wind speeds. I prefer if it star to spin at 2m/s or such. I know they dont produce untill 6+m/s...

Charge controller of some kind available.

What do you have that could work for me?

Here is 3 links that I have looked at. Pros and cons? 3phase vs DC voltage comming down? How to handle it?
Assume that I dont know jack about it and hit me with all info you got :)

500w but only 24V.
2kw from USA 24v max and 3-4mph atleast...
2kw from germany 2m/s and 48v


Hit me!
I plan to do some tests and see what I can find out and what smaller systems is doable for us (The DIY)

Links and all just throw at me
 
The one from Germany looks good; good kw output and 48V. Plus it's cheaper ;)

I personally would go with the 3-phase and do the rectifying later. This keeps the losses to a minimum, of course. I think most turbines can be configured for DC or AC as the output.

You might be able to get a discount from them if you mention you will be doing a review of the product. Worth a shot ;)

The 1st listing seller also sells a 48V 500W version as well.
 
Of course its hard to trust the numbers. Most of those cheaper ones wont be close to do what they are said to do. For instance i base a nominal of 10% in normal wind here of the total wattage. I need to get it up atleast 20 meters in air to see an 40% wind increase just to get it going i would say.

And its important that it starts to spin at 2-3m/s and will produce allready at 4 because the average where i live is 5m/s over a full year at 20 meter height.
 
Gotcha. Have you thought about going with a vawt? It turns much easier at lower speeds. You might have to put one together yourself, but you can get a better motor that way.

1KW Generator. Which, you could probably run two of these off 1 VAWT setup.
Plastic Polymer Composite Blades. Unless you make your own.


I actually plan on building a VAWT for my setup because there are so many trees around. The wind is actually too turbulent to use a HAWT (horizontal) setup. The VAWT would work more efficiently this way. Plus, you can put baffles on the VAWT to further channel the air directly into the peak spot of the blades to get them turning easier.
 
That motor is from atv carts and stuff. Same motor and what ive heard utterly crap to use as generator. Woudnt even go close to them :p
 
LOL gotcha. There's some that are used in the eBike world that I've heard good reviews on. but I don't know what the numbers are.

But of the above ones you listed, I'd go with the 48V AC model. It looks pretty stout, as opposed to the first one, which is a knock off. But it's still flimsy. If you have any high winds, you'll have issues with it.
 
Why not a future diy project with a long transmission system so that you can test different generators in a ground box and spend the money in the best regulator or the most versatile?
 
Dont have the time nor money to do such an advance project :)
 
Do you follow Going off grids channel, he'sbeen playingwith a turbine?

Not sure if it's anything like you're looking for...

 
yeah following him :) Since he started to get atleast some power that did wake my brain up again and even though I may not make any power i want to try it out atleast to have some experience in the field.
 
Ok, found the motor for you windturbine:


:p

Hello,

First I didn't read the whole conversation!

Do not buy instabreeze. It's from turkey and nod that good. If you want good stuff buy air-X stuff!!! Expansive but high quality. I have a instabreeze 1200W/p 3-phase and you need good break unit and inverter that special for 48V.

Rem module 03 is original from a Germany company but Ali selling a copy.
The trick is too program the inverter to get the best performance out of the turbine.

My setup is as follows

Turbine 1200Wp48V 3 phase

2xRem module 03

2x MasterVolt Windmaster 600Wp

The trick is too programming the WindMaster because I use 2.



I know you are very handy ;)
You can make self a vertical windmill from Wavin pvc pipes and escooter hub motors and a good controller with regeneration function. I have it on my escooter but don't know the name right now.
Take you time and search YouTube;) the benefits of a vertical windmill is that it works always and is alway maximum efficiency
 
Good with some info. But you are running the Instabreeze? How bad is it? The air-x is like 4 times the cost to the instabreeze.

Can you link the stuff in you mention? Im not sure if i look at the correct one.

Yes I could make one and have been thinking of it but it would be massive... unfortunately I have to work to make a living too... :)
 
I asked him about that earlier (12/30/17), he didn't say one way or the other. ???
 
They look almost too good to be true. Where I live I get quite a bit of West>East wind and my roof peak is North>South so the wind would get compressed going up the roof into the wind turbines at the top. @500W each, 2-4 would yield decent power.
 
VAWTs are real nice in turbulent areas, like around buildings and trees. They can be placed a few hundred feet from tree lines and still work. You don't have to put the turbine 200FT (60M) in the air to get decent wind. There are some that are just 50FT (15M) up and do really well.

A HAWT (normal fan style turbine) requires very straight blowing wind and needs to be really high to work effectively.

I wish I had one built for this winter. We are getting lots of wind. I could of used it to do heat dumping in the house to help keep it warm ;)
 
I get probably more straight wind vs. turbulent wind but I like the design of the VAWT's over HAWT's.
 
Not sure if VAWT is useable. If Im gonna have any wind I need to have it on my roof on my garage 6 meters up... :) I have not figured out how to handle or work such a device that high up on the roof. The normal wind thingy is easy to get up and down due to planning.

But it have been in my mind too but im not convinced is the best choice but with that said I have now knowedge in VAWT
 
VAWT are designed to work in turbulent areas so I'm not sure how important it would be to get it very high. Perhaps make a small scale version with your 3D printer and test it out?
