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)

1. Position the cursor onto EFF by using the arrow keys
(
,) and confirm with ENTER. The display shows the
values of the output electrical parameters of the
photovoltaic generator.

4. By using the arrow keys (
 , ) it is possible to set:
 the integration period (IP) which can be used by the
instrument when testing the parameters of a PV
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.
