The function of the inverter is to take the fluctuating power produced by the turbine and turn this into usable electricity - 230 volts at 50 cycle sine wave - the same as the national grid.
Having turned the electricity from the turbine into usable power this can be used by the property owner - to substitute for power which would otherwise be purchased from the grid - or can be sold back to the grid.
The important thing about an inverter is that it must load the turbine according to the characteristics wind power.
The power of the wind increases exponentially with wind speed.
This means that as wind speed increases wind power increases rapidly.
(to show the S shaped curve)
Because of the characteristics of wind power the inverter must load the generator exactly according to the performance characteristics of the generator.
This means that at low wind speed load is gradually applied to the generator.
As wind speed increases the rate at which load can be applied can be increased until the point is reached at the top of the power curve at which point the rate of application of load must be reduced up to the point of maximum power production.
