Operation of the wind generator propeller:
In winds below 7-9mph (3-4 m/s) the propeller will not start from a dead stop. In winds above 7-9 mph (3-
4 m/s), the propeller will begin to turn slowly, and after 1 to 10 minutes, depending on the wind, it will
reach an rpm where the blades are nearly invisible. Once started the propeller will continue operating in
winds as low as 2m/s (4mph).
In normal winds the charging current will begin in winds above 7-9mph (3-4 m/s) and increase rapidly with
