The following illustration shows the connected linear functions of a typical characteristic curve for the
Windy Boy. It shows feed-in AC power of the Windy Boy as a dependent variable of the DC input
voltage. The adjustable parameters "Vpv‑Start", "VdcWindStart" and "VdcWindMid", "VdcWindMax"
and "Pmax" are used to adapt the power/voltage curve of the Windy Boy to the particular wind
turbine system.
Figure 3: Characteristic curve function
The correct configuration of the parameters shown in the diagram is absolutely necessary to
guarantee optimal performance with wind generators from different manufacturers.
Characteristic curve operation
The characteristic curve of the Windy Boy only approximates the actual characteristics of a real
small wind energy system. Consult the manufacturer of your wind generator for its typical
characteristics before changing the curve parameters.
