Configuration step by step
Starting point
In menu
Function Generator
find the PV functions. Select here
group
PV EN50530 (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 film
or
cSI
the configuration continues
with
Step 2
.
Step 1-1: Adjust technology parameters
If technology
Manual
was selected in the previous screen, all
displayed 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
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
defined values.
Step 2: Input mode and solar panel base parameters
Selecting the input mode between
MPP
and
ULIK
determines
what pair of parameters has to be set in the configuration and
also later in the simulation. When setting pair Uoc/Isc, the other
two pair is calculated with factors and automatically set.
The open circuit voltage (
Uoc
) and the short-circuit current (
Isc
)
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 fill 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

When selecting
E/T
or
U/I
the configuration continues with
Step
4
, otherwise an additional step is required
