 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).
The Information menu item contains the following 4 sub-
menu items.

• Contact information

• System information (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)
Configured inverter address
–
Version of the operating instructions for the inverter

• Country parameters: configured country and param-
eters; see also p. 70.
• Self test: result of the last successfully performed self
test (only when the configured country is Italy)
