2. GENERAL DESCRIPTION
2.1. FOREWORD
The instrument is designed to carry out performance measurements (I-V curve) and quick
pre-testing (IVCK) of photovoltaic (PV) modules/strings in accordance with IEC/EN60891
and IEC/EN62446-1.
2.2. INSTRUMENT FUNCTIONS
The instrument can perform tests on Monofacial and Bifacial modules/strings up to
1500VDC, 40ADC.
Measurement of I-V Curve (I-V)
The following functions are available on the instrument:
• Activation of Manual or Automatic measurement (*)
• Measurement of Voltage/Current/Power under operating conditions (@OPC)
• Measurement of Voltage/Current/Power referring to standard conditions (@STC) in
accordance with IEC/EN60891
• I-V curve diagram and Power/Voltage under @OPC and @STC condition
• Direct comparison of the @STC values with the nominal values declared by the
manufacturer and display of OK/NO result
Commissioning test measurements (IVCK)
• Open circuit voltage measurement VOC
• Short-circuit current measurement ISC
• Display of results under @OPC and @STC conditions in accordance with
IEC/EN62446-1 and IEC/60891
• OK/NO evaluation of results
General characteristics
• The instrument is supplied in a carrying case with IP67 mechanical protection.
• Safety sliding cover on inputs
• Large graphic colour display (800x480pxl) with capacitive touch-screen
• Internal icon-based menus for intuitive user interface
