Peak = MPP
When the Gen. Ch. Curve menu item is called, the inverter
records the generator characteristic curve of the inverter and
then displays it (Fig. left). The following applies:
• The inverter traverses the 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. left).
• If the top of the curve is flat then the inverter can possibly
no longer feed power into the grid.
The Information menu item contains the following sub-
menu items.

• Contact info

• System info (see Fig. left):
Product designation
–
Serial number of the inverter
–
Information on the software and hardware versions of
–
the inverter (see example  in Fig. left)
Country setting (country currently set)
–
Inverter address
–
Version of the operating instructions for the inverter
–
• Country setting: country that is currently set and
country-specific grid parameters; see also P. 85.
• React. pwr. char. curve: reactive power characteristic
curve graph (only when prescribed for currently set coun-
try)
• Self test: result of the last successfully performed self
test (only when the configured country is Italy)
