Thank you everyone for the comments. Our average wind speed here in the Philippines is 3 to 7 mph and this turbine generate electricity in the slightest wind. It start at around 5 mph and at 8.2 mph it reads already 11 amps and at 15.5 mph wind it generates 35 amps. I've seen 50 amperes at 20 mph and 62 amperes at 23 mph wind. This reading was taken with my Fluke digital clamp meter since my panel meter reads up to 50 amps DC only. All these readings were taken with a 400 watts load on the inverter.
I am located in Iloilo City, Western Visayas and my place is near the airport. The tower
has a beacon light on top for warning system and this is 12 volts powered.
