2. GENERAL INFORMATION
2.1.
Description of the Product
The inverters of the SUNWAY M XS series are full-digital devices that convert DC energy produced by
photovoltaic (PV) panels – when radiated by sunlight – into AC energy, which is delivered to the grid.
A solar system for the self-generation of electric power is composed of two elements:
-
the PV generator, consisting of a set of PV panels;
-
the SUNWAY M XS inverter, delivering power supply from the PV generator to the grid.
Operation in parallel to the grid allows consumers to exploit the power supply produced directly by the
system when radiated by sunlight, and to deliver power which is not locally consumed to the grid, by
conferring it to the Grid Administrator. Therefore, residual power can be used by other consumers connected
to the grid, thus allowing the exploitation of the green energy produced by the PV generator, as well as the
constant operation of the same PV generator at its max ratings for optimum performance.
At night-time or when sunlight is weak, consumers can exploit the grid to power their loads.
All the parameter values related to the operation of the equipment may be easily programmed through the
touchscreen display and the parameter menus and submenus.
The inverters of the SUNWAY M XS series have been designed and manufactured in compliance with the
requirements of the “Low Voltage Directive” and the “Electromagnetic Compatibility Directive” and comply
with the prescriptions for grid connection applying to self-generation electric plants.
