1) Yes of course the generator size and wind speed and the load must all be proportional and the components (turbine blade pitch, controller, shaft, yaw drive, gear box, brake, motor type, etc.) must be properly designed, that's a given.
2) The inverter has a fixed frequency....... in your application it needs to be a 50 Htz frequency since your electrical grid and your loads are 50 Htz. The inverter frequency does not change. Don't get confused on the rotational speed of the turbine that is impacted by the wind speed. Frequency has nothing to do with the wind speed. The generator motor and the inverter are the 2 components that control the fixed frequency outputs. Both of these components must match each others frequency.
3) If the wind is less mph, then the turbine amp output is less and can thus support a smaller load. The generator and/or inverter frequency of 50 Htz each remains as constant.
4) If the wind is more mph, then the turbine amp output is greater and can thus support a higher load. The generator and/or inverter frequency of 50 Htz each remains as constant.
I hope this better explains that the turbine and/or inverter frequency has nothing to do with the rotational wind speed frequency. You are comparing apples to oranges...ie....... 2 different things:)
Whether the wind speed is 5 mph or 25 mph, the turbine and/or inverter are both generating voltage at a 50 Htz frequency.
The rotation of the turbine blades is called wind speed rated in mph and is not rated in frequency. The magnetic fields in both the generator motor and/or inverted are rated in frequency.
