2. GENERAL DESCRIPTION
2.1. INTRODUCTION
Dear Customer, thank you for choosing one of the instruments in our range. If used
according to the instructions given in this manual, the instrument you have just purchased
will guarantee accurate and reliable measures. The instrument is designed to guarantee
maximum safety, thanks to a newly conceived development, which ensures double
insulation and enables the instrument to reach overvoltage category CAT III 1000V DC
and CAT IV 300V AC (to earth)
The instrument has been designed as an accessory for an instrument, hereafter called the
MASTER instrument (see par. 4.3), for the purpose of carrying out testing operations on
single-phase and three-phase PV systems.
Together with a MASTER instrument, MPP300 is the ideal solution for testing and
analyzing the possible problems linked to possible low efficiency values of photovoltaic
systems
2.2. INSTRUMENT
FUNCTIONS
The instrument has the following features:
 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 means of a reference cell connected to unit
SOLAR-02
 Measurement of panel and environmental temperature by means of probe PT300N
connected to SOLAR-02
 Testing of PV systems with single/multi-MPPT inverter - single/three-phase AC output
 Parameter recording of a PV system with 5s to 60min programmable IP
 Internal memory for data saving
 RF/USB interface for transferring the data to the MASTER instrument
