① Period for a single yield value (here: day yield)
② y-axis:
Yield in kWh
n
With an extra
n
The scaling changes depending on the maximum value.
n
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 x-axis: input voltage in V
② y-axis: power in kW
③ Peak = MPP
'Gen. Ch. Curve' menu item is called, the inverter records
When the
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.
M : yield in MWh
