5. System
The solar inverter converts direct current from the solar cells into alternating current.
This enables you to feed your self-produced solar energy into the public grid.
Thanks to efcient MPP tracking, maximum capacity utilization of the solar energy plant
is ensured even in the case of cloudy sky conditions.
The string concept means that PV modules are always connected in series (in a string)
and/or that strings with the same voltage are connected in parallel to the solar inverter
with the aim of signicantly reducing the photovoltaic system’s cabling requirements.
8
Operation and installation manual SOLIVIA 2.5 AP G3 TR
The fact that the modules are connected in strings also means that the photovoltaic
system can be perfectly matched to the solar inverter’s input voltage range.
5.1 Data evaluation and communication
The integrated data display, processing and communication of the device enables
easy operation of the solar inverter. Monitoring of the operational status and signaling
of operational failures are capable of being called up over the device display. The data
interface enables the downloading of data which can be evaluated with a PC system
and guarantees continuous recording of operating data.
The best way of accessing this functionality is via the available accessories; comprehensive and seamless solar inverter monitoring is ensured.
The data read-out over the integrated interface and the display is possible only in solar
operation.
5.2 Technical structure of the solar inverter
A galvanical isolation of the solar inverter from the grid is achieved through a DC/AC
converter with an integrated high-frequency transformer. The photovoltaic voltage is
adjusted so that the maximum power output of the PV modules is also achieved with
varying solar irradiation levels and temperatures (MPP-Tracking).
The MPP range of the solar inverter is between 150 V and 450 V. This facilitates the
use of PV modules by a variety of manufacturers. Measures must be taken to ensure
that the maximum open-circuit voltage of 540 VDC is never exceeded. Please note that
the maximum open-circuit voltage will occur at the lowest temperatures anticipated. You
will nd more detailed information about temperature dependency in the data sheet of
the PV modules. The device’s power consumption is kept to a minimum.
The high-quality aluminum casing corresponds to protection class IP65 (water-jet-proof
and dust-proof) and is protected against weathering processes by surface renement.
The cooling characteristic prole is designed so that operation of the inverter is possible
with ambient temperatures from -25°C to +70°C.
A cooling characteristic prole is used for the removal of the power dissipation caused
through the voltage conversion. An internal temperature control protects the device
against excessive temperatures in the interior of the solar inverter. In case of high ambient temperatures, the maximum transferable power is limited.
The solar inverter is controlled by microcontrollers, which also implement interface communication and the monitoring of values and messages on the display.
Two independent and redundant microcontrollers control the monitoring of the grid,
which is consistent with the feed-in directives of your local utility company. This enables
an installation of the solar inverter in the in-house electrical grid.
Operator protection requirements are met by electrically isolating the grid from the
PV module. The electrical isolation between the grid and the PV module is equivalent
to basic insulation. Maximum operator protection is ensured by reinforced isolation
EN

Operation and installation manual SOLIVIA 2.5 AP G3 TR
between the grid, PV modules and accessible interfaces (display, RS485 interface).
Relevant standards concerning electromagnetic compatibility (EMC) and safety are
fullled.
The solar inverter is functional in on-grid operation exclusively. An automated isolation
point, which is approved by a certication agency, guarantees secure disconnection in
case of circuit isolation or interruptions in power supply and avoids isolated operation.
The disconnection equipment allows for automatic isolation for in-plant generation sys-
tems of nominal power ≤ 4.6 kVA, with single-phase parallel feed-in through the solar
inverter into the grid.

6. Installation
Installation and commissioning must only be carried out by qualied electrical experts.
The recommended local and national safety regulations should be complied with.
To carry out an energy measurement, a meter must be attached between the grid feedin point and the solar inverter (in accordance with all local and national safety regulations).
By means of the integrated anti-islanding protection, the function of the recommended
section switch is fullled in accordance with all local and national safety regulations.
For details, please see „10. Technical data“, page 34.
Caution: The secondary short-circuit current rating is increased at the transfer connection point to the public electricity supply system by the nominal current of the connected
solar inverter.

7.5 Ambient temperature
The solar inverter can be operated in an ambient temperature between -25°C to +70°C.
The device should be installed in a well-ventilated, cool and dry location.
7.6 Grid connection
The grid (AC output) is connected over a Wieland RST25i3S AC connector. You can
nd the correct allocation on the screw-type terminal connection of the connector. The
solar inverter must be connected to the grid over a three-core line (L, N, PE). The connected AC line must be switched potential-free before the disconnection or the insertion
of the AC connector.
The connection to the Wieland AC connector must be made with a exible line and a
conductor cross section of min. 2.5 mm² to max. 4.0 mm².
An automatic circuit breaker is to be provided in the line L upstream of every device,
with a nominal current of 25 A and tripping characteristic type B or C (please refer to
Mounting
plate
Locking screw
Locking screw
EN
13
Operation and installation manual SOLIVIA 2.5 AP G3 TR
your local country installation requirements and regulations for correct tripping characteristic type). In addition, attention is to be paid to the selectivity of the fuse unit
attached upstream of the automatic circuit breaker.
The solar inverter must be grounded via the AC connector’s PE conductor. To do this,
connect the PE conductor to the designated terminal. If you wish to integrate more than
one inverter into the installation, please proceed as illustrated in the drawings in the
appendix.
Please note the cable length and the cable cross-section, due to the risk of undesirable
temperature rise and power losses.
The AC connector is protected from unintentional disconnection by a clip mechanism
which can be released with a screwdriver.
7.7 Connection of PV modules
Before the photovoltaic system is connected, the polarity of the PV voltage at the MultiContact connectors must be checked to ensure that it is correct.
The connection of the PV module is implemented using Multi-Contact MC4 connectors,
where the DC negative pole is located on the connector upper row and the DC positive
pole on the connector lower row. The connectors are coded to prevent you from accidentally plugging them into the wrong terminal.
Please ensure the following at all times:
● That there is never any risk of anyone coming into contact with the solar inverter
connection terminals, due to the risk of dangerous voltages across them.
● That under no circumstances are the PV modules to be disconnected from the
solar inverter under load. If a disconnection should be necessary, rst switch the
grid off so that the solar inverter cannot absorb any further power. Next, open the
upstream DC disconnector.
The maximum input voltage of the solar inverter is 540 V. The maximum current load of
each individual Multi-Contact MC4 connector is 18 A.
The solar inverter has an insulation and grounding monitoring on the DC side. The
options can be congured in the Setup menu “S -> Solar ISO / GND” (see „8.3.7.1 Sub-
menu S: Solar ISO / GND“, page 29).
The insulation monitoring has two modes:
● ISO-ON-Error (the solar inverter is disconnected from the grid in the event of an
insulation fault)
● ISO-ON-Warning (the solar inverter indicates the fault but is not disconnected from
the grid).
Deltas solar inverters are factory-set to ISO-ON-Warning mode on delivery.
The grounding monitoring has two modes:
● PV+ grounding (grounding monitoring of the positive pole of the PV generator)
