18. On SOLAR I-V, press key () to access the second
screen which contains the values of the output DC
parameters of the strings according to the number of DC
inputs set (see § 5.2.1.1). In particular, in this screen:
 Vdcx = DC voltage of string x
 Idcx = DC current of string x
 Pdx = DC power of string x.
We recommend checking that the values of the electrical
parameters (Vdc, Idc, Pdc) are consistent with the system
being measured.

19. On SOLAR I-V, press key () to access the third screen
which contains the values of the electrical parameters on
the AC side of the inverter, consistently with the settings
made in § 5.2.2 (single-phase, three-phase 4 wires). In
particular, in this screen:
 Vacxy = AC voltage between Phase and Neutral (if
single-phase) or between Phases x and y (if three-
phase)
 Iacx = AC current of phase x
 Pacx = AC power of phase x
We recommend checking that the values of the electrical
parameters (Vac, Iac, Pac) are consistent with the system
being measured.

20. Keeping the three instruments near each other (max
distance approx. 1m), press the GO/STOP key on SOLAR I-
V to start testing. Consequently:
 The display of SOLAR I-V shows the message “rec. start
waiting”
 The display of SOLAR-02 shows the message “HOLD”
and the time, expressed in seconds, remaining before the
recording is started
 On MPP300, the STATUS LED turns on green (not
flashing)

21. Upon reaching the instant “00” after pressing the
GO/STOP key, the test is started and the three units are
synchronized with each other. In these conditions:
 The display of SOLAR I-V shows the message “rec.
running”
 The display of SOLAR-02 shows the message
“Recording…”
 On MPP300, the STATUS LED flashes green
