X-axis: Input voltage in V
Y-axis: Power in kW
Peak = MPP
When the
Gener. Ch. Curve
menu item is called the inverter
records the generator characteristic curve of the module and
then displays it (Fig. upper left). The following applies:
•
The inverter traverses the entire input voltage range and
records the power generated over this range. Duration: a
few seconds, is displayed.
•
The MPP is the peak of the generator characteristic curve.
•
This peak and the generator characteristic curve change
with the level of solar irradiation.
•
Multiple peaks are a sign of partial shadowing (Fig. lower
left).
•
If the top of the curve is flat then the inverter can possibly
no longer feed power into the grid.
