How much power will a small wind turbine output?
There are no firm international standard for how small wind turbines are Rated. Most grid connect wind turbines are given a power specification at 10 m/s (meters per second), the equivalent of 22.4 mph or 19.4 knots. In stronger wind speeds, they produce more .
We rate our small wind turbines at the standard of 10 m/s. Same as the industry level. Therefore the real useful specification is how much power will actually be delivered into a battery bank.
In real conditions the wind is rarely constant. So output graphs can only indication of instantaneous power at given wind speeds. The real measure of performance of wind turbine is “accumulated ampere hours” over a period of time (such as a day, a month, etc.).
Suppose the average wind speed is 5 m/s one day. The MW-200 delivers 1.5A at 5 m/s, then we
could estimate a daily yield of 24H X 1.5A = 36AH.
However the wind may blow at 10 m/s for 12 hours and be calm for another 12 hours one day, showing 5 m/s as the average that day. The wind turbine performance is quite different then.
The MW-200 delivers 7A at 10 m/s, thus 12H X 7A = 84AH.

About start-up wind speed.
Start-up wind speed is an important specification of small wind turbine. The MW series use low cogging 3 phase alternators designed specially for the small wind turbines. They can start-up smoothly at 2.4 m/s, and operate more efficiently in the range of 2.7--10 m/s. Also they take advantage of higher wind speeds to produce higher outputs steadily and safely....
