PVCHECK 5
2. GENERAL DESCRIPTION
2.1. INTRODUCTION
This instrument has been designed to carry quick checks (IVCK) on photovoltaic modules/strings
in order to verify the parameters declared by the manufacturer. In addition, this instrument
measures insulation/continuity on PV modules/strings/fields and evaluates the efficiency of a PV
field.
IVCK and insulation/continuity measurements may be performed in sequential order IVCK

Insulation

Continuity, or be carried out separately in manual mode.
2.2. INSTRUMENT FUNCTIONS
The instrument has the following features:
Continuity test of protective conductors (LOW
Ω
)

Test with test current > 200mA in compliance with standard IEC/EN62446

Manual calibration of measuring cables.
Measurement of insulation resistance on PV modules/strings (M
Ω
)

Test voltages of 250V, 500V, 1000VDC in compliance with standard IEC/EN62446

3 measuring modes: Field, Timer, String

Insulation test of unearthed metal masses
Efficiency evaluation of a PV installation in the short/medium term (EFF)

Measurement of DC voltage, DC current and DC power at PV modules/strings’ outputs

Measurement of irradiation [W/m
2
] by means of a reference cell connected to the optional remote
unit SOLAR-02

Measurement of module and environmental temperature by means of probe connected to the
optional remote unit SOLAR-02

Application of compensation relationships to DC efficiency.

Immediate evaluation of DC efficiency according to the limits set by the user


The instrument is provided 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 Auto
Power OFF function, which can also be deactivated, is availa
ble after approx. 5 minutes’ idleness.
