4. In order to guarantee the operator’s safety, disable the system being measured by means of
the switches/breakers upstream and downstream of the DC/AC converter (inverter)
5. In case of inverters provided with more than one power tracker (MPPT),
only leave the
string corresponding to the first MPPT connected
, as shown in Fig. 4. Then, it will be
necessary to repeat the operations described below by only leaving the string corresponding
to the second MPPT connected, then to the third, etc.
6. Bring SOLAR I-Vw or SOLAR I-Ve and SOLAR-02 nearer (maximum distance of 1m
between them).
All instruments must be switched on
(see the User Manual of SOLAR-2
for further details)
7. On SOLAR I-Vw or SOLAR I-Ve, press the
MENU
key, select the function
EFF
and press
ENTER
; wait for the two units to start communicating with each other. This condition is
highlighted by the contemporary presence of the following indicators:
Symbol
steady (not flashing) on the display of SOLAR I-Vw or SOLAR I-Ve
Symbol
steady (not flashing) on the display of SOLAR-02
8.
Connect the
C2
and
C1
inputs respectively to the positive and negative polarity of the
output string. Connect the
P1
and
P2
inputs to the phase and neutral conductors
respecting the colors as shown in Fig. 4
9. Connect the output connector of the DC clamp to the
IDC1
input.
CAUTION
BEFORE CONNECTING THE DC CLAMPS TO THE CONDUCTORS
Switch on the clamp, check the LED indicating the status of the clamp’s
internal batteries (if present), select the correct range, press the ZERO key
on the DC clamp and check on the display of SOLAR I-Vw or SOLAR I-Ve,
the actual zeroing of the corresponding Idc value (values up to 0.02A are
acceptable).
10. Connect the DC current clamp to the positive string output conductor
by respecting
the direction of the arrow
on the clamp itself as indicated in Fig. 4. Position the DC
clamp in point so far from the inverter and avoid that the jaws stay close to the negative
conductor
11. Connect the AC current clamp to the Phase L1 conductor
by respecting the direction
of the arrow
on the clamp itself as indicated in Fig. 4. Position the AC clamp as far as
possible from the inverter and avoid that the jaws stay close to the neutral conductor.
Connect the output of the clamp to the
IAC
input of the instrument
12. Power on the system on test
