A "cheap" wind turbine at Casto + solar




by Christophe » 05/07/07, 12:50

AIR X terrestrial wind turbine 400 Watts / 12 V for 850 €.

3 year warranty and it's not chinese.

The very complete Manual (for a manual): http://www.castorama.fr/media_aux/499167_a2.pdf

Learn more about Casto's site

The idea: to mount it in addition to our solar system

I hesitate (it blows a lot with us) to invest to test a purely resistive load (space heating or DHW) a simple 400W inverter and an electrical resistance should be enough.

It will simply heat up when the wind turbine turns (no storage), i.e. when the sun is lacking: ... Zen think what (stuff, idea ...)?

Hello,
Looking a little we find it at 750 Euros. (Air X)

Good machine, I have one in use for a good year.
The bp encountered are:
The noise of the blades (you will not take a nap nearby) : Cheesy:
The passage in safety which gives a big mechanical shock al "together. (It is to see and hear) : Cry:

So be very careful with the range of wind speeds at the precise place where you install it, taking care not to exceed the maximum speed (or as little as possible)

Otherwise good wind !!

Nice is it pretty good then a priori? :)

Some questions:

So you have the exact same model?

How many m did you put it on?

What assembly did you put "in the ass" rather at the foot (in the morning)?

For the maximum speed it is around 15 m / s (55 km / h) is that it?

Hello,

Yes same AirX model but in 24 Volts (intense cause)
Installed at 600m altitude near Toulon. It supplies a radio relay and its accessories.
So no noise for me !! : Cheesy:
The assembly is very simple because everything is integrated in the wind turbine case just a large amperage 24v battery (450 A / h)
It is supported by a 40 meter mast but is only 10 meters high. Our biggest problem is that very often it is safe because the wind is too strong (remains of the well-known mistral). This is why it is not very high because it is no longer useful to climb above.
Purchased in the Grenoble region at the above-mentioned price ......

Ok thank you for the info and do you have an idea of ​​its actual annual production (in kwh)?

Hello,

No idea of ​​annual production but it depends a lot on the wind speeds at the place where it is located (safe passage around 14/15 m / s)
Otherwise it feeds a site which consumes 25/30 permanent Watts plus a hundred watts approximately 3 to 4 hours per day.! (Roughly 1Kwh / day)
It is found on Ebay .....

reading the manual (48 pages) is very informative, I recommend it to all those who want to tinker in this area.

Certainly, but usually what we find is suitable for 220 V
I recall the good old law of ohm:

I = V / R

as for power: P = UXI

and let's not forget this old Joule: the resistance is proportional to the temperature: when you measure a load with the ohmmeter, it is not the load resistance, which is much higher.

So, this remark is relevant on condition of using loads at nominal voltage

The other problem is that the frequency is also variable: an inverter provides a stable frequency

Yes elephant, it is especially because it is easier to find heaters (whether it is for domestic hot water than air) in 220V than in 12V ...

I can't imagine tweaking something with old diesel glow plugs and an old PC ventillo ... : Cheesy:
