A good factory made windgenerator

[anteror]

Hello, I am new here.

I live in western Finland, on the sea side.

First I planned to build my own windgenerator, but I decided to test and seek a good one from factory made.

I have tested 8 windgenerators alltogether now.

Best result is giving 2kw model from ;

http://www.exmork.com/windturbine.htm

It has been in my other mast since januari 2009. It has seen 11 storms and Finnish winter. Its running and working good. I have winched it down for inspection few times. Ok

It is a 48v modell, but I have connected it via good big rectifier directly to my 24v NICAD 2000Ah batteries.

In my other mast I have Bergeys XL1, it gives really power only after 8-10m/s winds ?

Exmork gives easily 10-30amps at 5-9m/s.

Due to my experience I have ordered directly from Exmork factory their 5kw and a new one 2,5kw, models.

You can buy 6 units Exmork 2kw with the price of one Bergey.

They will come here in the end off this month.

I will share with you my experience about them.

I have lived "off grid" with these machines since winter -09 and made all my energy, in heavy winds heating too.(I have grid too, but dont need it now.)

My energy need is 8-12kwh per day.

All my lights are LED.

Newly built 115m2 low energy house.

Looking forward to have an electric car !(dont by anything else before)

Hello!  Welcome aboard.

My neighbour has that same model: Exmork 5kW.  Apart from trouble with the controller panel (which burned out due to incorrect installation) he is starting to see good results.  You might want research ways of improving the control system - but it depends on what you choose from the manufacturer and what the installer in Finland can provide for you.

What other machines have you tested and what results have you seen?  Do you measure and record data such as wind speed at your site?  Very curious!

anteror;

What I personally like to see is the 2000Ahr NiCd battery setup.

Wow! Have banks of them (12V 20Ahr/bank)but nothing that comes close to this size.

Would you happen to have extra info on these?

Pics would be great too!!

Cheers!

Hi

I couldn't find any pricing information on their site.

I dont like web sites that do not show their prices.

Anyway

I also would like to know what other units you have tested.

Thanks

To Bruce

My batteries are 7 years old used from a ship. They have full capacity and will have that at least 10-20years, after that you change the liquids.  

They use these in telecom sites, ships, hospitals etc.

Best knowledge about them I found from the importer of these batteries in Finland.

They install and maintain them and have experience about them.

These NICD or NIFE batteries are about the best for windpower.

Overcharge does not harm and you can take power out to the bottom limit.

Have you noticed these;

If I would need batteries now, I would go to :

http://www.alibaba.com/

And find NIFE or NICD manufacturers and buy directly.
