400W DC 12V Wind Turbine Generator With Controller For Marine, RV, Homes & Industrial Energy - By Happybuy Review

I like this turbine because it is very light. I connected it with a GTI. I had to purchase a new rectifier to connect it to the grid tied inverter. Overall I am very satisfied.

I built one of these to test a location for wind power, the unit voltage increases with wind speed. If you are serious about wind energy, you need a wind or hybrid controller to manage batteries, brake, free spin, etc. plus a resistor bank to give it something to do after your system is fully charged; otherwise is does put out wattage when the wind is really blowing hard.

There's a reason the rated current isn't stated. The manufacturer BLATANTLY lies about the power the generator can output. I ordered the 12 volt 500 watt model, which is supposed to be able to supply approximately 42 amps. The size of wire required to handle even 40 amps at the maximum standard temperature (90 degrees Celsius) is 10 AWG. The wires coming from the generator and controller are ALL 14 AWG, which can handle only 25 amps at the same 90 degrees. The controller is also only rated at…

Had to figure out most of this product myself as the instruction page was basically pics of a worker putting together a slightly different model. This could have been better with a little instruction. Other than that, it seems to work well with my modifications. Not using this for wind, so I can't comment on wind speeds and such.

The wind in my area blows about 10 to 15 mph. The Red light on the controller is always on. There's no charge going to my batteries. Not Happy with Happy buy.

Good quality, easy install. I haven’t been using it long but so far so good. It’s winter here now so the wind is high. That's my feedback!

This product does not generate the 400 watt voltage is says. That's my feedback. The voltage is below 1 volt regardless of wind speed.

the blades spun but no power was generated. All instructions were followed as detailed. I tried to contact the company for more help with no success and now can no longer return product as it’s been a week past the cut off date. This should was not due to user error I’m an electrical engineer and my neighbor who helped me is an electrician. Don’t waste your money.

It took over a month to get it,and when I got it there were no instructions,and wind have to be over 15 mph to get any power from it,,and I can barley get any power out of it,it looks good and that's about it

Does not work . It drains batteries instead of charging. And customer service is horrible about timely getting back to you. Almost impossible to work with

My husband and I bought this and are very disappointed with it. Takes a lot of wind to spin blades. It must because we haven't seen them spin once.🤬 we think it is a waste of money. We should have just saved our money and went to Missouri wind and solar instead.

Put this unit up and the very max is .64 amps in a 35 to 40 mph wind. I am going to use parts off of it to use on a Delco alternator for fun. It has an output of 95 amps.

This is advertised as a 500W turbine but I attached a very high speed drill to it an spun it up and it peaked at 22W. On its' own mounted on a 20ft pole in the middle of an open field I have seen it peak at 18W. All three phase wires are properly connected directly to this MPPT controller (https://www.amazon.com/gp/product/B07Z5QZ6RQ/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1). I also tested with the stock controller it comes with but that didn't do any better, the charge light on the…

Hooked it up to multimeter and impact drill. Mine produces about 80 volts at 2 amps. So about 200 watts? I am not for sure on the calculation, but for the price per watt, it is a better bang for buck than solar. Now I just need some wind.

Was going to install this turbine to try to offset my electrical use during peak hours. However when it arrived in the blades were partially damaged and without all the fastener hardware. I promptly returned it.Beyond the missing pieces and damaged blades the turbine itself seemed heavy duty made out of cast aluminum.I did note that the bolt pattern on the bottom was 4x 4.5” diameter. Finding a proper way to mount to the top of a pole would probably be the hardest part of the project.

Ok so I bought this to supplement my solar and here are some things I found.5-10mph starts spinning10-15 produces 10-50 watts15-20 produces 50-100 watts20-25 produces 100-200 wattsNot sure above that but mine has peaked at 220wattsSome other things to mention as well make sure you have the blades balanced before you put it up and to note that one turbine alone is not going to net you alot you need 2-3 before you get the good production out of a wind turbine system as wind speeds vary constantly

Started putting the blades on and the bolts are all to short, they won't even start in the threads on certain holes! May not come with a remote monitoring system for operation.

installed as instructed and placed in an open area 15 ft above ground level. With 20 mile per hour winds turbine would not generate enough amp to charge batteries. Added a volt/amp meter and it showed 12v but 0 amps when hooked up to a bank of batteries. batteries without a load read 11.8v and after 10 hours batteries were still at 11.8. Not worth the time and investment. Solar panels give you a more reliable source of power even without a constant source of sun light.

Definitely one very cool machine. Talk about very easy to install as well. I’d recommend buying the mounting pole if you can find one. I ended up going to the HardWare Store and bought 2, 10 foot by 2 inch galvanized steel piping sections and used a coupling that fit very tightly inside of each pole and was able to pound them together and then happened to find a flange that fit the cog of the wind generator perfectly. Bolted it on the pipe and ran the wires down so they popped out of the pipe…
