2. GENERAL DESCRIPTION
2.1. FOREWORD
This instrument has been designed to carry out quick tests (IVCK) on photovoltaic (PV)
modules/strings in compliance with standard IEC/EN62446.
2.2. INSTRUMENT FUNCTIONS
The instrument has the following features:
Continuity test of protective conductors (RPE)
Test with test current > 200mA in compliance with standards IEC/EN62446, and
IEC/EN61557-4
Manual calibration of measuring cables.
Measurement of insulation resistance on PV modules/strings (M)
Test voltages of 250V, 500V, 1000V, 1500VDC in compliance with standards
IEC/EN62446 and IEC/EN61557-2
2 available measuring modes
DUAL Measurement in a sequence of the insulation between the string's positive
pole (+) and PE and between the string's negative pole and PE.
TMR single timed measurement between the string's negative pole and PE.
GFL (Ground Fault Locator) function to search for positions with a low insulation
among the modules of a PV string (see § 6.5).
Measurement of open-circuit voltage and short circuit current on monofacial or
bifacial PV modules/strings in compliance with standard IEC/EN62446 (IVCK)
Measurement of open-circuit voltage Voc on monofacial and bifacial PV
modules/strings up to 1500VDC.
Measurement of short-circuit current Isc on monofacial and bifacial PV modules/strings
up to 40A.
Measurement of front and back irradiance through Bluetooth with remote unit
SOLAR03 and reference cell HT305
Display of results in OPC and STC conditions
Immediate evaluation (OK/NO) of test results
The instrument is also provided with an internal Database capable of storing up to 64 PV
modules (to be uploaded by the user), with backlit display, internal contrast adjustment
and a HELP key able to give a valid help to the operator while connecting the instrument
to the installation. An AutoPowerOFF function, which can also be deactivated, is available
after approx. 5 minutes
