I-V400w - I-V500w - SOLAR I-Vw - SOLAR I-Ve

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 (SOLAR I-Vw or SOLAR I-Ve) 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.

2.2. INSTRUMENT FEATURES

The instrument can perform the following tests:
Check Single phase PV installations (EFF - SOLAR I-Vw and SOLAR I-Ve)
 DC voltage and current measurements (1000V for SOLAR I-Vw 1500V for SOLAR I-Ve)
 AC TRMS voltage and current measurements
 DC/AC power measurement
2
 Solar irradiation [W/m
] measured 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 single/three-phase PV systems (MPP – SOLAR I-Vw, SOLAR I-Ve + MPP300)
 Measurement of 3 DC voltages and currents
 Measurement of DC string power and total DC power

 Annual degradation evaluation of PV modules/strings/fields
 Internal memory for saving test and Optical/USB interface for PC connection
Quick Check (IVCK)
 Fast test of open voltage and short circuit current up to 1000V DC, 15A (SOLAR I-Vw,
I-V400w) and up to 1500VDC, 15A (SOLAR I-Ve, I-V500w)
 Activation of manual or automatic measurement
 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 Auto Power OFF feature is available after about 5 minutes of idleness.
