Question 1

Had up for a month can not get to produce any 12v power there is ac output and little green light flashes but no 12 volt has been up in 20 to 40 mph

Accepted Answer

The simple reason for this poor results is that this unit is a piece of junk.  Mine arrived looking like it had already been used and was missing some bolts, etc.  The vendor went to great lengths to avoid the return of the unit, and finally offered a 50% refund if I kept it.  However, after setting it up and documenting results for over a month, it has never  succeeded in charging a 12 volt battery, even in high winds.  Live and learn.

Question 2

Is a rectifier built in to change ac to dc?  item description says 3 phase ac pmg which would require a rectifier.

Accepted Answer

Yes there is a rectifier that comes with it and it changes the 3 phase AC to direct current. + and -.

Question 3

Can the Blades be installed backwards affecting the output?^

Accepted Answer

The blades must all face the same way as they rotate past the same point.  The turbines put out the same power whichever direction the blades are set up to rotate. Don't expect much power at under 35 MPH winds. though.  At 25 MPH mine won't reach 12 volts with a 1 amp load on it. There isn't enough surface area on the blades and not enough windings in the alternator. That's my experience.  Try turning the alternator with a variable speed drill.  You'll need 300+ RPM  to get any power.  At 25 MPH winds, both mine turn at about 120 RPM, which will just barely light a car turn signal bulb.

Question 4

recently they updated these models too operate under lower wind speeds and produce the desired output rating. if ordered will i receive those blades??

Accepted Answer

we recently purchased this and received the blades pictured. I can say this thing starts spinning at very low wind speeds (2-3knots is all that is needed) and has been working very well in our setup.
