I-V Curve Test
V
OC
is a test for the maximum voltage that the solar panel can produce under standard test
conditions as required by IEC 62446-1 Clause 7.2. I
SC
is a test for the maximum current that
the solar panels can produce under standard test conditions.
To m e a s u re :
1. Turn the rotary switch on the PV Analyzer to I-V Curve.
The I-V Curve Table shows on the display and indicates if the PV Analyzer is connected to
the Irradiance Meter or PV model.
If not connected:
a. Push
IRR Meter to pair the Irradiance Meter with the PV Analyzer. For more
information, see Pair PV Analyzer to the Irradiance Meter.
b. Push
PV Model to select the PV model from the database.
When connected, the I-V Curve Table shows:
Irradiance live reading from the Irradiance Meter
Cell Temperature live reading from the Irradiance Meter
Nominal Values based on the PV model
2. Push
to view the I-V Curve Graph.
The I-V Curve Graph shows:
Nominal Curve based on data from the PV model
Area Curve shows the range of the min-to-max values of the Nominal Curve based on
the Nominal values
±5 % (Pass Criteria = 5 %)
3. Connect the red test lead to the positive connector of the PV Array and the blue test lead
to the negative connector of the PV Array.
Tip: Push
to see a connection diagram.
4. Attach the Irradiance Meter to the panel with the bracket.
5. Push
to start the measurement and create an I-V curve.
The display shows a progress bar.
6. Push
to cancel the test.
