are you happy with your wind turbine? - Page 2

I don't need to compute the output of a new turbine. That's all theory which I'm
not interested in. If you own your own turbine and
can give me your experiences about it's good points and its bad points, that's
what I would be interested in.

   I have an Airx403 to be used for camping.
It's rated 400W. I've never got better than 10 A (120W) in testing and
that's because I can't get clean air.

Turbulance and too close to the ground are real killers in getting decent
output.
In future I will test it on a farm, on top of a hill with no trees for
hundreds of metres. Then I'll know.

for starting with something too small. I was thinking of

comparison. I use a stainless steel 38mm (2inch) pole

that. 5A is the maximum I've ever seen. In upgrading I

enough to hold a big blade machine, and it's the only

with 12v. The pole is top clamped at 1.4m below the

metal apart from the blades. It has nice big bearings and

the aerogen brand but that's because I know nothing

 

Thanks for your feedback Norman.
do you think it might also be down to exagerated performance claims by the
manufacturer?
at http://www.wind-works.org/articles/sm_AirXtest.html  it says:
'During these tests I noted that the AirX was not meeting its power curve.
Previous measurements of the Air 303h and 403 indicated
that these turbines also failed to meet their advertised power curves. However,
the AirX failed by a much wider margin.'

Is the AirX a plastic body turbine? Have you ever serviced it or replaced
bearings? Would you recommend the AirX or not?  Thanks if
you can give more info.

I had a 403 for about ten years. It was very troublesome at first (it
started out as a 303), but worked reliably for about 6 years after
being updated by the factory. It never came close to 400W here, even
when it was screaming in 50mph winds. It failed many months ago, and
when I next take the tower down, I'll be removing it for good.

The only external plastic parts on the AirX are the blades and the
spinner. I've read about the independent tests and accept them. It's
been a while though, the factory may have made improvements by now.
I'd recommend the AirX *if* you accept that it should probably only be
rated at 200W.

 That's enough to light up your central light in the trailer for sure.
