Daily, monthly and annual yields can be displayed graphically in a
chart.
①
Period on an individual yield (here: day yield)
②
Y axis 1) 2) 3)
③
X axis: Time in hours/days/months/years
④
Total of all individual yields shown in the diagram, in kWh
The graphical representation can show annual yields for the last 20
years.
1) Yield in kWh
2)
With addition of ‘M’ : : yield in MWh
3) The scaling changes depending on the maximum value.

Peak = MPP
If the ‘Ch. Curve’ menu item is called, the inverter records the PV
generator characteristic curve and then displays it (Fig. upper left).
The following applies:
n
The inverter traverses the input voltage range and records the
power generated over this range. Duration: a few seconds; is
displayed.
n
The MPP is at the peak of the PV generator characteristic curve.
n
This peak and the PV generator characteristic curve change with
the level of solar irradiation.
The menu item
Information
contains the following sub-menu
items.

System info
(see Fig. left):
– Product designation
– Serial number of the inverter
– Information concerning the software and hardware version
of the inverter (see sample

in Fig. left)
– Inverter address
– Version of the manual that belongs with the inverter
