Hey Akis, quite a substantial system! good work! is it a dometic system?
I havent yet had experience with wind turbine - grid tie inverter setups so Im unsure of what the best practice is with connection. So far I have tested it with a 500W turbine connected to the batteries as I describe on the 12V DC page. Im pretty sure however that you connect the circuit up in the same way in your case to the inverter instead of the batteries. I dont see why you would need a diode?
The main things to consider that I know of are: the shunt needs to be rated above your maximum current value and secondly for saftey you could put a fuse in series with the voltage dividerand both RA resistors. You might also prefer to use the non-invasive hall effect method for current measurment which would increase the saftey.
Like I said my experience is currently limited to the smaller 500w turbine with battery connection so only try to implement the above if your happy that you know what your doing.
Let me know your thoughts and how it goes.
