OPERATION
3 SYSTEM OVERVIEW
3.1 General
Solar modules are
re photovoltaic devices that are able to
convert solar energy into DC current and voltage.
Solar modules can be connected in series (strings) or in
parallel to form an energy-generating
generating photovoltaic field.
The DC current and voltage produced by solar modules
mo
has
to be collected and transformed before it can be fed into the
public grid.
TTL inverters are devices for converting the DC current and
voltage produced by solar modules into AC current and
volt-age for supply to the public grid.
Depending on the model selected, TTL inverters may be
equipped with one or two separate DC inputs with
independent maximum power point tracking (MPPT). If an
inverter has two such independent inputs, the module
strings in the photovoltaic field can be installed at different
differe
positions and orientations to optimise the layout of the field
and maximise the energy it produces.
3.2.2 Photovoltaic panel ground fault
TTL inverters are designed to function with photovoltaic
panels that are isolated from ground. The positive and
negative terminals of these panels must therefore have no
direct connection to ground (earth). To ensure this, TTL
inverters incorporate integrated protection that constantly
monitors the ground connection and shuts down the inverter
in the event of a ground
und fault. The system also provides
immediate warning of a ground fault by means of an alarm
on the graphic interface.
TTL inverters can only be used with photovoltaic modules
that comply with the class A requirements defined by the
standard IEC 61730.
3.2.3
.2.3 Additional protection devices
TTL inverters are equipped with the following additional
protection devices to guarantee safe functioning under all
operating conditions:
- Active operating temperature control and automatic power
limitation that prevents over-heating
over
under abnormal or
out-of-range
range operating conditions.
- DC input and AC output overvoltage protection.
- DC polarity inversion protection.
- AC short circuit protection.
3.3 Touch screen
The inverter is equipped with a touch screen LCD display
user interface. In order to perform command operations it is
sufficient to touch the surface of the display
displ with a finger (in
alternative use materials dedicated to the use on touch
screen).
Do not use metal or excessively sharpened
tools.
The functioning of TTL inverters is completely automatic. As
soon
on as there is sufficient insulation, the inverter
automatically switches on and begins transforming the
current produced by the field. The inverter automatically
switches off again if insulation falls beneath the minimum
level required for electricity generation.
All regulation and control operations can be performed on a
touch screen LCD display on the inverter’s front panel.
3.2 Protection devices
In order to maximise energy efficiency, TTL inverters are
designed to function without a transformer. This
Thi means
there is no galvanic insulation between the DC input and
the AC output. TTL inverters are therefore equipped with
other protection devices to ensure
e safe functioning and to
confirm
m to applicable safety standards in the absence of an
isolating transformer.
former. These protection devices are
described in the following sections.
3.4 Dynamic
The LCD display allows to manage multiple screenshot with
scrolling text and interactive diagrams.
3.5 Stand-by
To save energy, the back-lighting
lighting system of the display is
turned off automatically if not used. To reactivate it, simply
touch the display surface.
3.6 Installer entry mode
For safety reason, it is warmly recommended to change the
password to access
ccess to installer entry mode (default
(
358).
The setting parameters available when entering the installer
entry mode must be managed exclusively by qualified
personnel since wrong setting can compromise the correct
operation of the inverter causing damages to the inverter
and safety risks. In this case, guarantee or manufacturer’s
liability claims for damages of any kind are excluded.
3.2.1 Anti-islanding
TTL inverters are equipped with advanced anti-islanding
anti
protection. This automatically disconnects the
t
inverter in
order to avoid islanding in the event of a grid power failure,
or in the event of voltage or frequency faults being detected
in the grid. Islanding can be dangerous for personnel
working on the grid and for power loads connected it. The
inverter’s anti-islanding
islanding protection conforms to all relevant
national laws and standards.

Turn on the AC connection.
Insert the switch (external) AC side protection.
The sizing of the string fuses must be carried out
considering the following two reports:
1) the rated current of the fuse (Irated) must not exceed
the maximum size of the fuse to be used in series the
string provided by the technical data of the PV modules
in accordance with the norm IEC61730-2
2) the nominal current of the fuse (Irated) must be
determined from the string current and the guidelines of
the manufacturer's sizing to avoid unwanted trips. As a
general guide, based on the short circuit current is the
photovoltaic modules (ISC) is the fuse size can be
calculated using the following formula: Irated> (1.4 to
1.5) xIsc
NOTE: The fuse with the previousr approximate
calculation takes into account a number of corrective
factors such as: the temperature derating of the fuse,
the increase of the Isc to vary with the temperature
increases.The maximum return current module and the
increase of irradiation. Actual on-site installation the
choice should fall on the commercial value that best
approaches the result obtained.
