PV module settings
Parameters of PV modules can be set in this menu. A database for up to 20 PV
modules can be created / edited. Parameters are used for calculation of STC values.
Note:
The database can be also created on the PC or mobile device and then sent to
the instrument. PCSW EurolinkPRO and some Android applications support this
feature.
