Question: Can I charge 12 & 24 v. using this?  also, do I need to buy an extra wire to go to the charge controller?
Document: Then one day came a strong wind which threw some tips out. After I removed all of the tips I added, the windmill rotates like crazy and the voltage easily reached 12V. This put some confidence back on me. After I got a full manual from the manufacture, I followed the suggestion to get a controller and plus a grid tie inverter. The system works perfectly, charging electricity back to my grid. As you look at it when wind blows, it looks so beautiful!
We will begin using the turbine power for our boat when we sail shortly. It appears to work well although we detect a bearing clicking noise.
I have had winds over 20mph here and this unit made no power. it is hooked up properly, have contacted aleko here in the states about it by phone one time and several emails. they are just buying time in hopes of not replacing a faulty unit. I would have been better off buying a wind max or a skymax. the turbines sold under the name gudcraft are the exact same turbines as these. don't waiste your money on these.
When I first got the wind generator, I was not quite confident about it. I used my electric meters to measure everything from voltage to current, which made me more concerned. What made me most concerned is its blades. The tips of the blades are almost in a plane perpendicular to the axis of rotation. So I put little tips on the ends of the blades with some angle toward the wind, which do make the blades rotate at almost any lower speed of wind.
I have had mine for about five months. First problem was my own. Did not know from instructions that it was 12v ac not dc. Finally read it off the label on the rotor housing. Ok, so now i have power.... wind came up and flexed two blades off. Luckily they did not damage anything but flew down and one landed fifty feet away in a field. I replaced the two broken blades, and winter set in. Apparently moisture got into the housing and then froze.
At least my infrastructure is in and i got a learning experience for 400$
Answer: no
