17. The display of SOLAR I-V will show the values of the
general electrical parameters of the system being
measured
In particular, in this screen:
Pdc = General dc power (sum of the string powers)
Pac = ac power (if single-phase) or sum of the ac powers (if
three-phase)
We recommend checking that the values of the electrical
parameters (Pnom, Pdc, Pac) and of the ac performance
(ac) are consistent with the system being measured (e.g.:
ac > 1 is not physically acceptable)
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 the User Manual of SOLAR I-V)
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 (see – SOLAR I-V user's manual, 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)
