5.2. EFF
– EFFICIENCY TEST SETTINGS FOR PV INSTALLATIONS
The purpose of this measurement is to evaluate the DC efficiency of a photovoltaic
installation, with the possibility of obtaining a positive or negative result of the
check/recording depending on a limit on the
nDC parameter, freely set by the user. For this
test, the use of the optional remote unit SOLAR-02 is necessary (see § 6.1)
