13.2.10 MPP Tracker (not available with PV*SOL®-N for grid connected
systems only)
MPP trackers are not standard system elements, but are produced especially for the
various stand-alone systems. They are also partly integrated into other system parts
(charge controller).
For the MPP tracker the following data is required:
Reference:
The text entered is shown as the file reference in the load file dialog.
Nominal Output:
The nominal output corresponds to the power output of the PV generator.
Upper and Lower Voltage Levels for the MPP Range [V]:
The MPP tracker functions within this voltage range. The MPP tracker finds the optimal
voltage for the PV array within this range, so that the array’s power output is maximized.
MPP Adjustment Efficiency [%]:
The adjustment efficiency provides a measurement of how close the MPP tracker’s working
point is to the PV array’s maximum power point (MPP).
Characteristic Curve – MPP Tracker:
This button opens the ”Characteristic Curve – MPP Tracker” dialog, so that the you can
enter the conversion efficiency depending on the input power. The programme requires
seven values to be entered for the characteristic curve: the efficiency at 0, 5, 10, 20, 30, 50
and 100% of the nominal power.
Click on Graph to view the characteristic curve.
Click on Load to load one of the MPP tracker files provided, to check on the values and
correct if required.
Click on Save or Save as… to save the values you have entered, either in the current file or
as a new file. A message appears before a file is overwritten.
Close exits the dialog without any message appearing.
