# 400-Watt Wind Turbine Power Generator for 12-Volt Systems

• Great for charging 12 volt battery system for Off-Grid use
• Can be used for land or marine applications
• Min 1.5in Schedule 40 steel pipe for installation, not included
\$429.99 /each

## Product Overview

Produce up to 400-Watt 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.

How is it possible?
It is Wind Power = 0.6* V^3 [W/m^2]
Wind Power = 1.2 [m^2 your rotor] * 0.6 * 9^3 = 524 W but this is only wind power it not stop velocity of wind bihind turbine. Your wind turbine can intercept only 59% of wind power. It said Bernoulie.
Bernouli said that It is power your turbine:
P ~ 0.59 * 524 = 310 W if efficiency is 100% :)
But I doubt that efficiency exceeded 50 %.

The specifications say that 28 mph is required to reach 400 W.

18-20 mph winds are needed to produce power from the wind turbine. 20 mphs and over will provided the maximum output of power on the 400W wind turbine.

Yes. This product comes with it's own charge controller for a 12 volt system, so if you have a 12 volt system, you could hook it up from the enclosed CC to your battery bank. I have three charge controllers. Two have 10 Grape solar panels (which are awesome) attached to each, and one has several Harbor Freight panels (which are almost useless, but I have them, so I use them) attached. I have also had a

I have also had a 12 volt battery charger attached at the same time. As long as everything is the same volt system, everything will work.
On the other hand, if you want to use a different CC, make sure it is compatible with wind power.

Check your charge controller to make sure it is compatible for wind/solar. Some charge controllers are NOT compatible for wind/solar both. Also,if it is compatible make sure you don't go over the wattage or amperage readings of your charge controller. EXAMPLE:
1.-600 watt charge controller wind/solar 200 watt solar array 400 watt wind turbine this will work.
2.-600 watt charge controller wind/solar 400

Will this work with grid-tie type inverters to feed power back into the power grid?

If you use your own charge controller instead of the one that comes with the unit, you can hook it up to any voltage system you like. The one that comes with the unit is 12/24.

Unfortunately, our wind turbines are made to supply power to 12 volts or 24 volts charging systems.

## Customer Reviews

400-Watt Wind Turbine Power Generator for 12-Volt Systems is rated 3.2 out of 5 by 14.
Rated 5 out of 5 by from Good off-grid product The quality seems good. You need a steel pole to mount the unit on and the manual says 20ft high. I use this product to help provide power to an outlet building. It keeps my 12V AGM batteries charged to run lights and electronics. Charging kicks in around 12mph and best charging after 20mph. This is a perfect compliment to my small solar array. I love using off-grid products!

Rated 5 out of 5 by from Make sure you install it high enough - Great Product I just finished installing it on the weekend so it is a little early to comment on the long terms quality but so far, I love it! I am getting much more out of this wind turbine than my solar panels. I was advised to install it at least 20 feet high and I am glad I did as it seems the wind is much better above the trees. It took me and a friend most of the afternoon to install it but we did a good job and watching it spin and create energy puts a smile on my face.

Rated 2 out of 5 by from Just an ornament 3 blades are so narrow doesn't matter if wind is blowing 10 mph. It doesn't generate as it should. I made a mistake buying this. So many out there start spinning at lower speeds.. it MIGHT work if more or wider blades..

Lightweight and fairly easy to install (although we have a very electrically inclined friend-I don't know if I could have done it alone). It works as a supplement to our solar power in the winter, but we live in a very gusty, windy area. It takes quite a bit of wind to actually spin the blades-no gentle breezes, but we are happy with it!

Rated 2 out of 5 by from Bought two of them. Not that happy. The wind generator is easy to install. And quality looks good. But the blades are to thin and will not start making power until wind is above 18 mph. I have install at other tower sites 450 watt ari wind generators and they start making power at 5 mph and full power by 15 mph. Will not be buying any more of these.

Rated 1 out of 5 by from 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
