1.2. For whom this manual is intended
This manual must be read by:
•Installers
•Operators
•Plant manager
Please refer to section 1.9.
1.3. Operating principles
Figure 2: Single-wire diagram of a standard SUNWAY TG TE inverter
The SUNWAY TG TE inverters include the following functional blocks:
DC Input Unit
The DC Input Unit allows connecting the inverter to the photovoltaic generator. It is provided with 8 fuse-
protected inputs, on-load switch, input EMI filters and SPDs. It checks the ground isolation of the PV
generator.
Static Converter
The Static Converter comprises the forced switching IGBT stack and the control board. The Static Converter
implements the most advanced features of the inverter, such as the control logics, the current and voltage
measures, the interface protections integrated into the control software, the autodiagnostics functions and
the serial communications.
Output Filter
The Output Filter transforms the PWM output of the converter into sinusoidal voltage.
AC Output Unit

MODULAR SUNWAY TG
TE OD
INSTALLATION GUIDE
14/139 Rev. 03 –01/06//2018
The AC Output Unit comprises control devices, such as the Contactor for the connection to the grid that
can operate as an Interface Device (please refer to section 4.3), the output EMI filters and the output
MCCB.
The inverter is provided with an interface device operating on minimum and maximum voltage / frequency
thresholds in compliance with the applicable standards.
Figure 3: Block diagram
Once the SUNWAY TG TE is connected to the photovoltaic generator and is properly started (see section
Error! Reference source not found.) the control system synchronises with the grid and closes the parallel c
ontactor when the PV field voltage exceeds the starting voltage value.
The inverter will then operate as a generator of sinusoidal current with a power factor that is typically equal
to 1.
The integrated MPPT (Maximum Power Point Tracker) algorithm constantly keeps the working point of the
PV field at the maximum power delivered.
The grid frequency and the grid voltage values are constantly checked during normal operation. This allows
detecting undesired islanding operation. Islanding detection can be performed by an external relay
according to the regulations in force (see section 4.3.1).
The plant data can be read from the LCD display/keypad placed on the front wall. The plant data includes
the active energy and the reactive energy, the operation time and the temperature of the internal
components. The keypad allows accessing all the inverter measures and programming parameters.
The inverter is provided with one Ethernet port for the connection to the remote monitoring system, both in
local mode and in remote mode (see section 4.9).
The Data Logger board is available as an option board. It is a telecommunications unit between the inverter
and the connected String Box. It stores local production data and allows connecting to the Santerno Remote
Monitoring (see section 8.7).
Several diagnostic functions are integrated in the inverter logic, such as the constant check of the program
memory integrity, the PV field isolation monitoring, the detection of the temperature of the internal
components, the detection of the input / output overcurrent, the control of input fuses.

EXPLOSION AND FIRE RISKS
The risk of explosion or fire may exist if the equipment is installed in a room containing
flammable vapours. Do not install the equipment where there is a risk of explosion or fire.
PROHIBITION
The product described in this manual has not been designed to operate in potentially
explosive atmospheres. Consequently, installation in such an environment is strictly
prohibited.

MODULAR SUNWAY TG
TE OD
INSTALLATION GUIDE
20/139 Rev. 03 –01/06//2018
PROHIBITION
It is forbidden to make any technical or mechanical modifications to the cabinet even
when out of warranty.
Elettronica Santerno is not responsible for any risks that may arise due to unauthorised
alterations, modifications or tampering.
2.2. Intended use
The SUNWAY TG TE inverters are digitally controlled appliances which convert electrical energy from a DC
power source produced by photovoltaic (PV) panels into an AC current which is then delivered to the grid.
The SUNWAY TG TE inverters may only be used as described in this manual. The DC power supply must
come from the PV field only. The AC output must be parallel-connected to the grid only.
Any use other than that described in this manual is to be considered inappropriate and therefore improper.
2.3. Qualified technical personnel
All work on MODULAR SUNWAY TG TE OD products must be carried out by skilled technical personnel
only. By skilled personnel it is intended persons who have been suitably trained to carry out the work in
question.
To commission and use the MODULAR SUNWAY TG TE OD inverters, personnel must know and
understand the instructions for installation and use. In particular all safety warnings must be strictly
observed.
2.4. Specific dangers linked to photovoltaic (PV) systems
PV systems have certain characteristics which are the source of additional hazards and are described
below:
•A live current source is connected. Depending on the operating conditions, there may be live voltage
from the PV generator or from the electrical grid. This must be taken into consideration, particularly
when disconnecting parts from the system.
•Very high DC voltages are involved (with no periodic zero crossings) hence failure or the incorrect
use of fuses or plugs may cause electric arcs.
•The short-circuit current of the PV generator is only slightly higher than the maximum operating
current and furthermore is linked to radiation. This means that fuses maynot always blow in the event
of a short-circuit.
•The PV generator grid is usually an IT type, i.e. it is only earthed in the event of a fault or energy
leakage. For connection to PV fields with earthing pole, connection is of the TN type, but the earth
connection is protected by a fuse which may trip in the event of a single fault.
•In the event of a fault (for example a short-circuit), cutting off a generator with a high number of
branches may prove to be somewhat difficult. Take great care to ensure each sub-field disconnect
switch has been opened before going near the devices installed in the technical room.
2.5. Execution of work
Maintenance, configuration modifications and management operations require the involvement of all
production and maintenance personnel. These activities must be carried out in observance of health
and safety regulations.
The Standards and Laws governing this aspect vary depending on the personnel involved, methods of
access and/or the tasks which may be carried out on the product and envisage constructive measures aimed
at guaranteeing adequate levels of safety.
Standard EN 50110-1, second edition, identifies the people who are granted access to the product:
•Person in charge of running the electrical system (System Manager).
•Person in charge of work activities (Works Supervisor).
•Skilled electrician.
