2. GENERAL DESCRIPTION

2.1. Introduction – PV and NPV systems
The instrument allows a totally new approach to the measuring world when dealing with
photovoltaic systems and mains analyses on single-phase and three-phase electrical
systems; the combination between instruments provided with microprocessor and the
Windows CE technology allows analyzing a huge amount of data in such a simple and
quick way as with no other system available.
Further in this manual, the following acronyms will be used:
PV systems:

Single-phase and three-phase photovoltaic systems.

NPV systems: Single-phase and three-phase non-photovoltaic electrical systems.
MPPT: Maximum Power Point Tracker (see § 10.3)

CAUTION

This manual covers two models: SOLAR300 and SOLAR300N. In this manual,
these models will be generically referred to as the “instrument”. In general,
whenever one of the following topics is dealt with:
 Flicker (Pst, Plt)
 Starting current / inrush current measurement
 Analysis of fast transients on voltages (spikes)
 EN50160 analysis (performed by the instrument)
 Use of the accessory MPP300
this is to be considered (even if not expressly indicated) as referred to
model SOLAR300N only


2.2. FUNCTIONS
This meter is able to perform:
 Real-time display of the values of the electrical and environmental quantities

(irradiation, temperature) of a photovoltaic system for generating single-phase or three-
phase electric power.

 Calculation of the values regarding the maximum efficiency point.
 Real-time display of the values of each electric quantity of a single-phase and three-

phase, 3-wire or 4-wire system, harmonic analysis of voltages and currents up to the
49

th

harmonic, voltage anomalies (dips and peaks) with 10ms resolution, Flicker (Pst,

Plt) display of the parameters of the unbalance on voltages, inrush current routines
and voltage spikes with 5

s resolution

 Real time display of any input signal waveform, histogram graphics of harmonics

analysis and vectorial diagrams of mutual angles between voltages and currents.

 Recording (saving the values of the electric quantities over time in the instrument’s

memory) the values of the electrical and environmental quantities (irradiation,
temperature) of a photovoltaic system for generating single-phase or three-phase
electric power.

 Recording (saving the values of the electric quantities over time in the instrument’s

memory) of this values: TRMS values of voltages, currents, corresponding harmonics,
Flicker active, reactive and apparent powers, power factors and cosphi, active,
reactive and apparent energies, voltage anomalies.

 Saving (by pressing SAVE key) of a “Instant sampled of instantaneous values of any

parameters present at instrument input inside memory.
