User questions & answers

Question:	how do you tighten the propeller and to stop the shaft from turning , i tried to used to stop the shaft using Allen key or screwdriver did not work
Answer:	Hold one blade and turn the Allen counter clockwise while in the nut, or hold the Allen in the nut and turn the blade clockwise.
Question:	Is there a wiring diagram with the unit? I did not see one in the box
Answer:	No it’s on the converter
Question:	If my average wind speed in 8 mph and I consume an average of 1000 kwh per month, how many units are needed to satisfy that demand
Answer:	It's a little more complex than that. If the wind blew all the time at 8 mph you might generate 600 Watts in a full 24 hour period (25 watts an hour). Without any consumption. Then you would have to store that generated energy before you could do anything with it. You really need a constant wind of 12-14 miles per hour to generate 12 volts at 3+- amps which will turn on a small light but only keep it on as long as the wind it blowing.
Question:	What wind speed is required? I’m baffled that such an important detail is not in the description
Answer:	Since folks will think of miles per hour for wind speed: The minimum rated wind speed of 8.2 feet per second is equal to 5.6 miles per hour. The maximum rated wind speed of 39.4 feet per second is equal to 26.9 miles per hour.

User questions & answers

Question:	How long does it take to charge the battery
Answer:	If the turbine is constantly spinning, it will be fully charged within 6 to 8 hours (be sure the battery box is set to "IN" and you are using a rechargeable battery).
Question:	Does it come with the generator and digital multimeter
Answer:	This kit comes with a reversible generator/motor with wire connector, but it does not include a digital multi-meter.
Question:	Does this really charge batteries/phones etc etc
Answer:	No. This kit will only light up the tiny red light that's included: NOT anything else - no batteries, NO phones.
Question:	can we adjust the blade angels to 15, 30, 45, 60, 75 ? Need this for kid's science experiment to find most efficient angle of the blade. thx
Answer:	Yes you could change the blade angle but not precisely. It's mostly by trial and error.The white blades need lot of wind speed. The blue ones work with a pedestal home fan.
