Graphical yield (day, month, year)
Daily, monthly and annual yields can be displayed graphically in a Chart.

Period for a single yield value (here: daily yield)
y-axis:
– Yield in kWh
– With an extra M: yield in MWh
– The scaling changes depending on the maximum value
x-axis: time in hours/days/months/years
Total of all individual yields shown in the diagram, in kWh
The graphical representation can show annual yields for the
last 20 years.

Generator characteristic curve
1
2 3
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.
Information
1
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. 77.
• 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)
