3.11.15.8 Conguration step by step
Starting point
InMENU->FunctionGenerator->2ndpage->XY-Tableyouwillnd
the PV functions. Select PV DIN EN 50530 (PS).
Step 1: Technology selection
The extended PV function requires to select the panel technology of
the solar panel which is going to be simulated. In case cSI or Thin
Film don’t match your requirements or you are not sure about their
technology parameters, select Manual.
When selecting Thin lm or cSI thecongurationcontinueswith
Step 2.
Step 1-1: Adjust technology parameters
If technology Manual was selected in the previous screen, all dis-
played technology parameters can be adjusted by tapping on them
and entering the desired value. It’s recommended to adjust these
values very carefully, because wrong settings can result in a PV
curve which doesn’t work as expected.
When resetting the device, these values are reset to defaults which
are the same as with technology cSI. Also see the overview in
3.11.15.3. It means they don’t necessarily have to be adjusted. If any
of the other technologies was selected, this screen would be skipped
andtheseparameterssettothedenedvalues.
Step 2: Enter the solar panel’s base parameters
The open circuit voltage (U
OC
), the short-circuit current (I
SC
), as well
as voltage (U
MPP
) and current (I
MPP
) in the expected MPP are the
base parameters to calculate a PV curve from. U
OC
and I
SC
are upper
limits which are usually read from the data sheet of a solar panel and
entered here for the simulation. Two parameters each are connected
viathellfactors:
U
MPP
= U
OC
× FFu / I
MPP
= I
SC
× FFi
Step 3: Select simulation mode
For a description of the available simulation modes see 3.11.15.4.
Furthermore, the recording feature can be enabled (=activated) here.
TherecordeddatacanlaterbestoredtoUSBdriveasCSVlewith
button SAVE records to USB, after returning to this screen from the
simulation run. Also see section 3.11.15.7.
When selecting E/T or U/IthecongurationcontinueswithStep 4.
Step 3-1: Load day trend data
If mode DAY E/T or DAY U/I was selected this additional screen will
appear where you can load the required day trend data (1-100,000
points) with button LOAD day curve from USB stick and from a CSV
lewithaspecicformat(see3.11.15.5) and name (see 1.9.6.5).
There is furthermore the option to enable (=activate) the interpolation
feature (see 3.11.15.6).
