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
