Hey Akis
The RVDa and RVDB resistors are used for the voltage measurment.
The Rsens, RA, RB, Opamp and transistor are all needed for the current measurment.
Maybe one thing that isnt clear in the circuit diagram is that the microgeneratore voltage which is labeled as 12V in the diagram actually varies between the battery voltage (if you have one connected) up to potentially 20V depending on loads and how fast the turbine is spinning.
Hope that helps :)
