It's been hooked up for two weeks now and the battery voltage hasn't raised even a hundredth of a volt yet.
Not that the turbine hasn't been spinning, it has! It spins in a very mild wind; it just doesn't produce 12 volts until it is spinning so fast that you can't see the blades. I've had 15 MPH wind gusts with no charging. Tests I have run indicate it has to be spinning 4 to 5 revolutions per second to output 10 VDC.
That's about 250 RPM, and moving pretty quickly, above that speed the black dot Indicator I put on the center hub begins to blur and speed measurement becomes difficult. Fearing the unit was defective I took all the blades off and mounted it and spun it manually as fast as I could and managed to get it to 12 volts after a few tries, and finally up to 17 volts for a moment. So it is capable of putting out the proper voltage to charge a battery. Since I was only able to get it going that fast for a moment I was unable to measure the current output.
Today it's been windy all day and it's been spinning most of the time, but there has been no charging yet, save your money.
Update, today we had sustained 30 MPH winds with gusts up to 50MPH and the wind turbine was able to charge a single deep cycle battery from 12.75 volts up to 13.25 volts with a highest current of 0.7 amps. Since I'm not likely so see many days with these kind of winds, it falls very short of it's rated 300 watts or 25 amps. I still wouldn't recommend it to anyone. The wind speed was checked with a Lacross weather station anemometer. It rarely puts out 12 volts and so far never more than 1 amp. Actually today is the first time I was able to measure any current output at all.Read more ›
We tried two different units with the same result.
We connected it to an oscilloscope and we see a full wave rectified sine wave output with a peak voltage of 12.5V. So it does not appear to have bulk, absorption, float control - which is really important if you want the battery to last for any length of time. I think the "charge controller" is noting more than a full wave retifier - which is not going to maximize the battery life and/or fully charge the battery.
Might work to charge a 6V battery, but not a 12V battery. Even if you only have a 6V battery, you will still need a charge controller - as connecting directly will overcharge the battery. Such a controller would necessarily have to deal with the voltage this device generates - so it would likely have to be a custom one.

Does not produce any voltage except at extremely high wind. Not good for charging a battery bank. Nice toy.Published 8 months ago by Michael
thls cannot be a good turbine becasue you need a non even number of blades!!! If fight the opposite blade...stupid design.Published 23 months ago by maui
