2. GENERAL DESCRIPTION
2.1. INTRODUCTION
The instrument was designed to perform complete yield test on single-phase (and three-
phase if combined with optional accessory MPP300) PV installations with calculations of
efficiencies (only SOLAR I-V) and to perform all I-V curve tests on single modules (panels) or
complete strings of photovoltaic (PV) plants in order to verify the reference parameters given by
the manufacturers. Therefore, the meter is an ideal solution for troubleshooting any PV
installation
2.2. INSTRUMENT FEATURES
The instrument can perform the following tests:
Check on Single phase PV installations (EFF - only SOLAR I-V)
 DC/AC TRMS voltage and current measurements
 DC/AC power measurement
 Solar irradiation [W/m
2
] measurement by use of reference cell connected to unit SOLAR-02
 Module and environ. temp. measurement by means of probe connect to SOLAR-02
 Use of compensation relationships on PDC measurements
 Immediate evaluation of result OK/NO of a test
 Checks with programmable IP from 5s to 60min
Testing of single/three-phase PV systems (MPP – only SOLAR I-V + opt. acc. MPP300)
 Measurement of 3 DC voltages and currents
 Measurement of DC string power and total DC power
 Measurement of 3 AC TRMS voltages and currents
 Measurement of total AC power
 Measurement of irradiation [W/m

2
] by using reference cell
 Numerical and graphical results of I-V curve with 4-wire method
 Comparison of results with standard conditions (STC) and OK/NO final response
 Serial resistance measurement of PV module
 Internal customizable database for definition up to 30 PV modules
 Internal memory for saving test and Optical/USB interface for PC connection
Quick Check (IVCK)
 Fast test on PV modules and strings of voltage and current up to 1000V DC, 10A
 Immediate evaluation (OK/NO) of test results
The instrument has an innovative electronic function selector to simply set operations with
internal parameters, a backlit display, the contrast adjustment and a HELP key in order to
give a valid help to the operator during the meter’s connection to the plants. An
enable/disable AutoPowerOFF feature is available after about 5 minutes of idleness.
