- Refer here for the specifications of the D400. a) What power output should you be able to supply from the 24V D400 at 15.4 m/s? b) If the wind drops to 2 m/s, what will the output power be? c) According to the performance graph what is the maximum power you can obtain from the 24V D400? There is a possibility of installing the turbine on top of a 20m high mast instead. Assuming that Zo=0.012, what would you expect the wind speed to be at that height?
