Generator characteristic curve
Information
747.431
① x-axis: input voltage in V
② y-axis: power in kW
③ Peak = MPP
'Gen. Ch. Curve' menu item is called, the inverter
When the
records the generator characteristic curve of the inverter and then
displays it (Fig. upper left). The following applies:
The inverter traverses the input voltage range and records the
n
power generated over this range. Duration: a few seconds,
is displayed.
The MPP is the peak of the generator characteristic curve.
n
This peak and the generator characteristic curve change with
n
the level of solar irradiation.
Multiple peaks are a sign of partial shadowing (Fig. left).
n
If the top of the curve is flat then the inverter can possibly no
n
longer feed power into the grid.
The menu item Information contains the following submenu items.
n Contact info
System info (see Fig. left):
n
– Product designation
– Serial number of the inverter
– Information on the software and hardware versions of
the inverter (see example ① in Fig. left)
– Inverter address
– Version of the instructions for the inverter
Country setting: country that is currently set and country-spe-

(only when prescribed for currently set country)
Network: network parameters, partially configurable under
n
