� 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.
See Section 11, p. 65.
� 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).
The Information menu item contains the following 4 submenu
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 parameters;
see also p. 70.
• Self test: result of the last successfully performed self
test (only when the configured country is Italy)
