1. SCOPE OF THIS MANUAL
Elettronica Santerno is committed to update its User Manuals available for download from santerno.com with
the latest software version officially released. Please contact Elettronica Santerno if you require technical
documents related to previous software versions.
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.
2.2. Benefits
−Wide range of supply voltages: 330 to 845 Vdc;
−Full-digital DC/AC conversion through 32-bit microprocessor obtained with PWM technique and
IGBT bridge ensuring high efficiency, high reliability and low distortion of the grid current;
−Transformerless topology;
−Die cast aluminium enclosure for maximum robustness, thermal performance and weight
optimization, suitable for outdoor installation (IP65-rated);
−DC disconnect switch ensuring maximum safety when maintaining the inverter (optional);
−Input filters and output filters for the suppression of conducted disturbance and radiated disturbance;
−Testing circuit to check the isolation resistance between the input and the earth;
−Operation in parallel to the grid, power factor=1;
−Fast connection through quick-coupling MC4 connectors for the connection of up to 4 strings;
−User interface based on graphic touchscreen display, 240x320 pixels, 262,000 colours for user-
friendly control of the inverter functionality;
−RS485 serial link with Modbus protocol for remote monitoring and programming (optional);
−Wi-Fi connectivity for the access to LANs and interaction via smartphones;
−Remote Technical Support if the inverter is connected to the Internet;
−Power supply from the grid in order to maintain operation even in the event of weak solar radiation.

PROGRAMMING INSTRUCTIONS SUNWAY M XS 7500TL

2.3. Operating Principle
The power conversion system (inverter) is connected directly to the PV field. By using a high-switching
frequency IGBT bridge, the DC coming from the PV field is converted into AC at the grid frequency. The
transformerless architecture ensures maximum efficiency without affecting safety: the system monitoring
current leakage to earth is integrated into the inverter (integrated RCD) and the redundant grid coupling
devices ensure proper safety even in the event of single fault.
The EMC filters for the suppression of electromagnetic disturbance, the isolation sensor monitoring the
isolation to earth of the PV panels as well as the device controlling the operation in parallel to the grid are
integrated into the inverter. Therefore, no additional device external to the inverter is required.

2.4. Main Standard Integrated Functions
This section contains a brief description of the equipment functions, to allow users who are not familiar with
the operation of PV fields to better understand this manual.
Device for constant isolation control:This is a device which constantly checks the isolation between the
earth and the polarities of the PV field and the earth. This function is obtained by measuring the isolation
resistance: the equipment is factory-set to detect isolation loss when the isolation resistance between polarity
+ or polarity – and the earth drops below 850 kΩ.
MPPT (Maximum Power Point Tracking): A sophisticated computing performed by the microprocessor
allows the inverter to detect the optimum operating point of the PV field, corresponding to the max power that
can be produced by the field depending on current solar radiation conditions.
Automatic Disconnecting Means:This device automatically disconnects the self-generation plant from the
grid when parallel operation is no longer possible. This typically occurs when the grid “opens” due to
maintenance needs or to safety circuit tripping. This function allows the inverter to instantly disconnect from
the grid, thus avoiding unwanted stand-alone operation of the plant and electric shock hazards for the
operators working on the grid. Trip times and levels are factory-set according to the applicable safety
standards. To modify the factory settings, please refer to the sections relating to the inverter programming.
The ratings of this safety function have been certified as prescribed by the Grid Administrator.
When required by the Grid Administrator, a simple self-test procedure performed via the touchscreen display
allows checking the efficiency of the grid disconnecting device.

3. BASIC INSTALLATION
The basic installation consists in connecting the basic elements for system operation (grid and PV generator)
in a plant equipped with only one PV generator and one inverter.
Advanced configurations of the SUNWAY M XS inverter are covered in section 4. Fully read the basic
installation instructions before carrying out the advanced configurations.
3.1. Caution Statements
This section covers safety statements. The non-observance of the safety instructions below may cause
serious injury or death and equipment failure. Carefully read the instructions below before installing, starting
and operating the inverter.
Only competent personnel must carry out the equipment installation.
KEY TO SYMBOLS:
DANGER Indicates operating procedures that, if not correctly performed, may cause
serious injury or death due to electric shock.
CAUTION Indicates operating procedures that, if not
respected, may cause serious
equipment failure.
NOTE Indicates important information concerning the operation of the equipment.
SAFETY STATEMENTS TO FOLLOW WHEN INSTALLING AND OPERATING THE EQUIPMENT:
NOTE Always read this instruction manual
thoroughly before starting the
equipment.
DANGER Always earth the equipment
CAUTION The SUNWAY M XS must be powered by a photovoltaic field only, and

DANGER
CONNECTION TO THE PV FIELD – When exposed to solar radiation,
the photovoltaic panels produce DC
voltage that is applied to the
inverter.
ELECTRIC SHOCK HAZARD –Do not touch the electric parts of the
inverter and do not operate on the inverter when it is powered. Always wait
at least 20 minutes
from the instant when the DC and AC supply is
removed from the
inverter before carrying out any operation, because
electric energy is accumulated inside the inverter.
Do not operate on the equipment when it is powered.
Before operating on the electric connections, remove both DC and AC
voltage from the equipment and wait at least 20 minutes.
EXPLOSION AND FIRE –The risk of explosion and fire may exist if the
equipment is installed in presence of flammable fumes.
Do not install the
equipment where there is a risk of explosion and fire.
CAUTION
Do not connect supply voltages which exceed the rated voltage. If voltage
exceeding the rated value is applied, the internal circuits may be damaged.
In
the event of installation in presence of flammable and/or explosive
substances, please consult the relevant applicable standards.
In the event of an alarm, consult section 4.3.6 Alarms Menu.
Only restart
the equipment after the problem has been rectified.
Do not carry out isolation tests between the power terminals or between the
control terminals.
Make sure that the screws on the connection terminal boards have been
properly tightened.
Observe the environmental requirements for installation.
DANGER Certain parts of the product (side walls, heatsink and reactors)
may reach
temperatures as high as 100 °C.
Take all the necessary precautions to
avoid burns.
DANGER
Do not remove the inverter lid during installation. Removing the lid may
affect the IP rating of the inverter and may damage the internal parts.
Removing the lid voids the inverter warranty.
