Southwest Windpower Air X Wind Generator

Southwest Windpower Air X Turbine

Southwest Windpower Air X Turbine

The Southwest Windpower Air X wind turbine is an excellent choice for adding renewable, supplemental power at a reasonable price.

According to Southwest Windpower , the AIR is by far the world’s number one selling small wind turbine. The model featured here is a 12 Volt 400 watt generator which can supply power to appliances and electronics. The Air X incorporates a new microprocessor-based technology that results in increased performance, improved battery charging capability, greater reliability and the reduction in the “flutter” noise created by the machine.

The Air X uses a microprocessor controller for efficiency and noise reduction. The controller allows for peak-power tracking of the wind by optimizing the alternator’s output to efficiently deliver energy to the battery bank. The controller will also control blade rotation speed eliminating the buzzing noise commonly found with most small wind turbines. The Air X has an exclusive Auto-Brake-feature that slows the Air X to a silent spin when the batteries are charged thus extending bearing life and reducing noise.
This wind turbine would pay for itself in no time; it costs about $600.00 USD

  1. Hello, This is a nice article and I have enjoyed reading stuff on this blog. I work for WindEnergy7.com and I build and install wind/solar hybrid systems. For just under a thousand bucks we have the smaller rooftop mounted turbines that connect with a solar panel to give clean reliable power. You see, since the wind is stronger in the winter months, sun is stronger in the summer months, we designed a system that is attractively priced, that gives an even flow of energy year round. Wind power scales down in size to be perfectly feasible for a homeowner sized system to provide power for their home. Our turbine is about twice as powerful for the money and is a more sturdy design. Have a look before buying, this 400 watt turbine is only for sailboats, not much power.Small DIY Wind Turbine Kits

  2. I’m not sure about your statement that the Air X is an excellent choice. I had one for eighteen months. The first sixteen months the thing produced almost no electricity. I sent it back to Southwest Windpower who were helpful and returned it within two weeks. It then worked very well for two weeks until we had a 60 knot breeze. It promptly disintegrated. The braking system seems to have failed,the internal wiring cooked and the machine head flew off the mast and slip rings to land 20 yards away destroying the blades. Since then Southwest has not answered any mails. Wonder why? Survival wind speeds overrated??

  4. Initially I was happy just to see the unit spin, and I thought it was producing healthy amounts of energy. I was also happy to observe ocassional 17..18A current, but was puzzled by the fact that the current dropped to downright zero quite often although the wind conditions did not change.

    Monitoring the unit I realized that the zero current situation was indeed a stalled windmill, which indicated too high wind speed (slow blink). Well, since I had very accurate wind speed readings, measured at tower top next to the AirX, I could tell right away that the wind is not the problem, and kept scratching my head thinking what on earth could be wrong…

    Nowadays as I understand the problem thanks to accurate datalogger information, I can tell there is nothing wrong with the site, installation, or my measurements. The problem lies entirely within the AirX, and I have the data to show that.

    So, I am quite unhappy with AirX as it only peaks at max power, and then goes into stall, just like many others have observed and tested. Even with consistent 12..14 m/s wind the same happens, output averaging well below 200W, and daily energy production severely diminishes - to something below 30% of the spec. Note that the manual says the limitation kicks in at 15.6 m/s, not at 12 m/s.

    It is apparently a design flaw with the AirX, and it is merely a 180W device than a 400W unit as claimed by SWWP. Several independent tests have showed that, see for example these two:

    http://www.detronics.net/airx_report.pdf
    or
    http://usasolarwind.com/southwestwind.pdf

    Since I installed the datalogger, I have measurements taken every second, with 1 minute min/max/avg values saved for later analysis now for well over 1.5 year. That is more than 50 million samples, and close to 1 million min/max/avg values along with same number of wind speed readings. All the data I have from last 1.5 years clearly shows what can also be visually observed on site.

    Only when the wind speed stays below 12 m/s, the output is continuous – but at 0..200W range – very poor average compared to 400W what the unit is supposed to provide. As soon as wind speeds go above 12 m/s, the unit reaches to over 200W, but stalls better half of every minute. Reaching to 400W peak does not help anymore if the unit is stopped >50% of time.

    The next one will not be an SWWP turbine.

  5. Sorry to disagree But I ran my guest house ( in Mozambique, on the beach ) using a 403 ( the previouse model ) plus 120W/h of solar panels - for 6 years ! it was noisy in high wind ( i believe they have improved that problem ) But otherwise it was Brilliant ! I had superb service and support from the agents ( Navtech, south africa ) and even if you halved the power output I still don’t know of a cheaper power supply ( W/$ ).

    The Problem you describe sounds like a tolerance or setting fault NOT an intentional and un-resolvable design flaw. If your agent/ supplier won’t fix it then contact SouthWest direct - come on now , its not some conspiracy to get our +- $600.

  6. Following my comments of the 24th 0ctober 2008 when my Air X Marine disintegrated, Southwest Windpower sent me a brand new turbine. It worked fine for a couple of weeks, then one of the yaw wires pulled out due to faulty factory soldering. It is back with Southwest again for warranty repairs!

  7. I am interested in buying an Air X 400W OR AIR Breeze 200W for my RV, I have 2 x 6 volt deep cycle batteries crossed to make 12 volts, if my batteries accidentially go as low as 7 or 8 volts will the Air X 400W or the Air Breeze 200 Watt recharge them back to 12.9 volts? Can you advise me what are my best options and what is the minimium AMP Hour Batteries I should have for the system to work best??

  8. I have an Air X on my cruising boat, I installed it with the help of an electrician. As the weather was starting to turn we had to leave our slip and catch our weather window. Since it was untested we figured we could rely on solar for a few days and then do the final hook up. Well we did in 30 Kt and the generator never went above 1 volt and the breaking system did not seem to work, we need to fix it since it we are a non carbon boat.

  9. All I can say about my air x is it is pretty much worthless. Some times it spins up only to be stopped by what must be the brakeing mechanism. As that happens the windmill turn to the right stopping the blade. It cycles like that most of the time never producing much energy.

  10. Hello
    I think I have the solution tomthe low power problem if you care to void the warranty. There are several output wires inside the case from the stator to the rectifier that are not connected.
    I just installed this and it is 15′ up and the wind is gusty and 20mph, the unit doesn’t spin and just chases the wind.

  11. Hello again,
    The positive and negative sleeves on the yaw shaft ohm identically, no matter what leading/following polarity arrangement is used as a controll. huh?

  12. The ohm value is not 1

  13. Well its spinning up a storm in this post storm winds that seem steadier than storm gusts….now no volts or amps and the stop switch does not stop the wind from humming the blades, the regulator blinks twice and does not charge, or at least the light, off, does not indicate. My battery is very low/ dead, and coming to life slowly by bridging a controller to get the minimum volts for charging. Does the Air-x have a simiolar requirement, if so I can’t find it in any manuals. Stmped again, double stumped, how is it spinning now anyway…Tom

  14. I’m ready to go 100% solar and wind here in the solar and wind plus area of Kingman Arizona.

    I was interested in this product but looking at the almost D grade customer input on the product, I’ll be looking elsewhere.

    Too bad
