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)

system. The following values can be selected: 5s, 10s,

30s, 60s, 120s, 300s, 600s, 900s, 1800s, 3600s.

 The FS of the DC clamp used for measuring DC

current with value selectable between 1A  3000A

5. Press the SAVE key to save the settings made; the

message “Data saved” will be displayed for a few

seconds. Press the ESC/MENU key to exit without saving

and go back to the previous screen.
