Produce up to 400 watts of power for free in your own back yard. The wind turbine will produce more power up to 400 watts at 28 mph. If the wind dies down the turbine will continue to produce power in winds as low as 5.6 mph. This wind generator is used to charge 12 Volt batteries and mounts on any 1.5 in. Schedule 40 pipe. This wind generator is a great way to get power to cottages, cabins, work sites, and other places where power from the electric company is too expensive or not available. Power from the wind generator can be used with an inverter to run small TVs, DVD, players, phones, lights, radios, power tools, laptops, fans and electric razors. it has a marine grade coating to withstand harsh environments. A wind charge controller is included with the generator to get the ideal charging current from your wind turbine to your 12-Volt battery or bank of batteries. The body is made from cast aluminum and is safe for high wind speeds, up to 110 mph. The assembly is easy and is only 5 parts, the body, a nose cone and 3 blades. Blade diameter: 46-in.

  • Starting charging at the low speed of 7 mph
  • Carbon fiber blader ensure low noise
  • External MPPT controller with LCD power output display
  • Weather resistant construction to withstand harsh weather elements

Rated 4.0 out of 5.0 by i have 2 other wind turbines and like the performance and the value of the Nature Power turbine. I like the watt meter. The green LED light is a little too bright. Good value for the money. June 13, 2013
Rated 5.0 out of 5.0 by 400 watt wind turbine I bought this for two reasons, the first was price and the second was the instore shipping saved me a few bucks. I had seen a very similar wind turbine in a lab at the college I am attending but that was less important to me than the price. I put the wind turbine up and prior to break in, the wind speed to start the blade pin wheeling was 11 mph wind speed. Break in happened over night with 30 mph winds and the blade started to turn at 7 mph. at 9, I would start to see the watts on the meter, and at 11 mph, I had good charging power. since I am studying wind power I am placing the turbine at different altitudes to study obstructive wind flow and power loss on wind energy. Even so, with the unit installed at just about tree top, I was seeing a lot of power, but not the type that would make the system usable. At a level 20 feet above the tree top, the wind power was steady and stable and I was impressed with the model a lot more than I would have thought I would be. easy start up, and strong power output (measured in watts) in decent winds was surprising. (I have read lots of reviews on units and normally I do not know if the ones writing it have a basic fundamental understanding of wind power. this is part of my study as a wind turbine tech) the 3 phase was an easy hookup. I will tell you at full power (rpm on the blades) the blade brake takes a bit to stop. do not expect it to stop as suddenly as the disk pads will do for a move car. the blade tip speed is rated at 270 mph at 28mph winds, and I think this is correct. it does howl, and there is a distinct noise when the blades are cutting into the wind. I have no trouble sleeping through it but I could see some people complaining. for the cost, (including the tower that I built) this is one excellent purchase for use with stand alone systems. (my system is a hybrid solar, now wind, and in the next few weeks, hydrogen generator back up) March 24, 2014
Rated 1.0 out of 5.0 by Nature Power Wind Turbine 400 Watt Easy to hook up. I had a charge controller that jump around all over the place and couldn't read it. I waited almost 6 weeks before I got a replacement charge controller. I had to order a new set of blades as something hit the blades during a bad wind storm. I also had to wait almost 6 weeks for that order also. They do not answer their phone, as the manager at HD left several messages, and he said they never returned his calls. After getting a replacement charge controller it went out again after 6 days. Then the wind turbine just stopped turning. So if you buy this, and want to repair it a lot, and it is not fun when it is 20' or 30' on a pole, like I have been doing, good luck. HD is refunding my money, and I am buying a different wind turbine from HD, as they have been very helpful with this problem, and others also. December 24, 2014
Rated 1.0 out of 5.0 by unworthy I have several wind turbines at the ranch on several cabins, i liked the concept of this unit, but it has never delivered. After many hours on the line with the tech support at nature power, and having done all there recommendations, the unit is still not performing according to there specifications, 90 % of the time with winds under 20 miles per hour it will over speed and shut down. today they said i may have a bad unit, but of course i have to go and find my receipt because they don't do warranty from the factory site....Buyer Be Ware November 4, 2014
