3 Introduction
With this device you have acquired a solar inverter for connection of photovoltaic systems to the
grid. This European solar inverter can be used in and is approved for the following countries:
Belgium, Czech Republic, France, Germany, Greece, Italy, Portugal, Spain and United Kingdom.
The solar inverter is characterized by its advanced housing design and state-of-the-art high-fre-
quency technology, which enable the highest levels of efciency.
The solar inverter includes monitoring units, such as anti-islanding protection. The function of the
anti-islanding protection (automatic isolation point for in-plant generation systems) stipulates com-
pliance with the specications of DIN VDE 0126-1-1, EN 50438, ENEL G.L., RD 1663, RD 661, UTE
15712-1, Synergrid C10/11 and G83/1-1, and compliance with the directives for parallel operation
of power generation plants on low-voltage grid of your local utility companies. These are declared
by certicates (see § 13).
The inverter is usable indoors and outdoors (IP65).
In the following technical description, the precise functions are explained to the installer, as well
as the user, which are required for the installation, operational start-up and handling of the solar
inverter.
4 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 efcient 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 signi-
cantly reducing the photovoltaic system’s cabling requirements.
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.
4.1 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 ca-
pable 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 (e.g. WEB´log); com-
prehensive and seamless solar inverter monitoring is ensured.
The data read-out over the integrated interface and the display is possible only in solar operation.

6 Operation and installation manual SOLIVIA 3.3 EU G3
4.2 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 tempera-
tures (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 re nement. The cooling charac-
teristic pro le is designed so that operation of the inverter is possible with ambient temperatures
from -25 °C to +70 °C.
A cooling characteristic pro le is used for the removal of the power dissipation caused through the
voltage conversion. An internal temperature control protects the device against excessive tem-
peratures 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 con-
sistent with the feed-in directives of your local utility company and DIN VDE 0126-1-1, EN 50438,
ENEL G.L., RD 1663, RD 661, UTE 15712-1, Synergrid C10/11 and G83/1-1 (anti-islanding protec-
tion). 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 between the grid, PV modules and accessible
interfaces (display and RS485 interface). Relevant standards concerning electromagnetic compat-
ibility (EMC) and safety are ful lled.
The solar inverter is functional in on-grid operation exclusively. An automated isolation point, which
is approved by a certi cation 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 systems of nomi-
nal power ≤ 4.6 kVA, with single-phase parallel feed-in through the solar inverter into the public grid.

5 Installation
Installation and commissioning must only be carried out by qualied electrical experts.
The recommended safety regulations, the technical interface conditions (TAB 2000), as well as
DIN VDE 0126-1-1, EN 50438, ENEL G.L., RD 1663, RD 661, UTE 15712-1, Synergrid C10/11 and
G83/1-1 specications, should be complied with.
To carry out an energy measurement, a meter must be attached between the grid feed-in point
and the solar inverter (in accordance with your local utility company directive concerning „In-plant
generation systems on the low-voltage grid“).
By means of the integrated anti-islanding protection, the function of the recommended section
switch is fullled in accordance with your local utility company directive.
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.
6 Installation of equipment
6.1 Installation location
• Install the device on a non-ammable support base.

6.5 Ambient temperature
The solar inverter can be operated in an ambient temperature between -25 °C to +70 °C.
The following diagram illustrates how the power supplied by the solar inverter is reduced automa-
tically in accordance with ambient temperature.
The device should be installed in a well-ventilated, cool and dry location.
6.6 Grid connection
The grid (AC output) is connected over a Wieland RST25i3S AC connector. You can  nd the cor-
rect 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. 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.

6.7 Connection of PV modules
Before the photovoltaic system is connected, the polarity of the PV voltage at the Tyco connectors
must be checked to ensure that it is correct.
The connection of the PV module is implemented using Tyco Solarlok 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 indi-
vidual Tyco connector is 18 A.
The solar inverter has an insulation and grounding monitoring on the DC side. The options can be
congured in the Setup menu “S -> Solar ISO / GND” (see § 7.3.8.1).
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)
• PV- grounding (grounding monitoring of the negative pole of the PV generator).
In these modes the solar inverter remains in feed-in operation and will not be disconnected from the
grid in case of a fault. The error message “PV+ grounding fault” or “PV- grounding fault” will appear
on the display.
If you need to connect the positive or negative pole of the PV system to meet requirements set
out by the module manufacturer, you can do this. Earth continuity must be implemented close to
the inverter. We suggest using Deltas grounding kit “Grounding Set A Solar” (EOE 99000115). The
grounding connection is monitored and should be congured in the Setup menu (see above).
Alternatively, it is possible to turn off the insulation- and grounding monitoring:
• ISO / GND OFF.
