Primus Windpower AIR X WIND TURBINE LAND 400W 12VWrite a review

Very pleased with the delivery of product and the Alternative Energy store.

First 8 mo went ok then it started not charging right and light would only blink called alt energy store and was prompley helpe they sent me a new circute bord with compleat instructions on how to install it and clean the brush wrings i folowed the instructions whitch were excelent and had it runing just fine even better the when it was new it now starts charging in 5 mph wind and puts out in higher winds up on opening it up it looked like grease from the yaw bearings has goten into the brushes right from the shiping stage . my advise would be for any one purchacing one to clean the brush area be for installing . it works fine and i have had excelent help from people in the know . this is a good product and priced right . If you plan on bying one feel free to contact me .
just rember in making the tower make it ez up ez down mine is on an old dish bracket and can be up and down in 5 min by my self and i am 60 years old and cripled !! top of pole is 26' hi .also i live in a 2 wind area but in the winter i get lots from the little air x i also have some solar 170 watts but don't get much in the winter from that .so the air x is main stay in the winter mo. even wet snow dosen't seem to bouther it . i highley recomend the air x to any one that wants to have some ele no mater what else happens and use as much as you get extra to off set your ele bill i have gone from $220.00 a mo to $90 to $110 a mo ele bills by using what i can from my air x and solar . my system concests of 5 115amp hr deep cycle batteries from wall mart and a 175 wat harber freight inverter on 24-7 also have a 5000 watt aims inverter that will run my well pump and do the washing machine in a pinch . this set up will get you by if all else fails .total cost for every thing i have is a round $2500.00 including wiring batteries and inverters
cheep for peace of mind and savings i have had so far in 2 years this will have paid for it's self in my ele savings

By far the best small wind turbine I have seen...owners manual is well written and very informative....company support was superb....nic`e to see quality made in America again

I bought this on impulse because it was an all in one starter solution,
to help me learn more about wind generators. So far so good! It seems
well designed and easy to install. (Still working on a more long-term
tower).

Got it up in a few hours, starts right at 7 MPH, very little noise. (Sounds like a fan in gusty winds) from 30 ft can not even hear it. Instantaneous response to winds. In stop mode turns very slowly in high winds, in charged up stop, almost stands still. I will add a second one this fall.....

The power generation curve is pretty steep and narrow. You'll need almost 20 mph to start producing anything worthwhile. In a 30 mph wind it does it's job very well. In a 40 mph wind power output will drop off considerably. When shorting the output wires, it shuts down very nice and stays shut down, which is important in high wind areas. I had a whisper 200 that disintegrated in a high wind. If you don't have the wind, it's not for you. If you've got the wind, it'll do as advertised.

Very matured 3 generation design. Good manual.
Can easily handle high winds. Very silent.
Hardly hearable. Adjustable regulation setpoint.
Pros: Excellent Design! MPPT charging.
Cons: Works only in quite much wind! LED hardly visible
in daylight. Effect very sensitive to turbulence.
Conclusion: In non-windy locations is a Solar Panel better!

I'm using two of these turbines to power a remote research facility. They provide more than enough power to keep 3 laptop computers, satellite modem and wireless router running all day every day, and were very simple to install. They easily paid for themselves in the first month of operation since I didn't have to fire up the old gasoline generator once. My only complaint is with the customer service at Southwest Wind. The circuit board went out on a different Air X I own, so I ordered a replacement kit directly through them. They accidentally sent the wrong part, and unfortunately after 6 months and many phone calls I'm still waiting for them to send the right part, which of course they charged me for. One more try and I'm going to have to send the dispute to Mastercard to deal with.

These are great for a back up for your PV system, but they do not seem to be efficient as our PV's even though we do live in a windy area, but I would recomend for a back up.

We are very happy with the service in purchasing this product. The unit is easy to set up.The employees are ALL very helpful.
We would like to see a change in the blades, as so they would start nad hold in a breeze condition. We have had trouble with not starting or continueing to spin when the breeze cycles.

We are attempting to locate it in a more open area at this time.

Easy to install. Works pretty well, but my opinion is that the tail is´too short. The wind turbine swing´s around its own vertical axel too easily.

Your going to get more daily power by spending the money on a small solar panel assuming you have a controller already.
Thought I would get a little more than 3 to 5A at the coast.
As the manual says, double the wind speed and your output goes up 8X. To put it another way, Lose wind speed and the output goes down by a factor of 8.
I am a heavy electrical user. 20 hrs/day. If I were charging my RV house batteries, it should work fine.
Now the good - It is FUN - I now can't wait for the wind..

I have had both of these wind turbines over the years and have installed them for others.
One big problem is the blades do not hold up and start hitting the pole, which then shatter the blades. I have had one turbine that I had to replace blades every year for three years straight. At $98 a set it is not too cost effective. Others have went two years at most before I relpaced them. I now have another one on a customer that is out and I want Southwest to replace them and I get no reply. So when it comes to service these units don
t hold your breath.
