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 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.

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 renement.
The cooling characteristic 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 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

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 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 qualied 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 fullled 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. Installation of equipment

7.1 Installation location

● Install the device on a non-ammable support base.

● Avoid installation on resonating bodies (light construction walls etc.).

● Installation is possible both indoors and in protected outdoor areas.

● An increased ambient temperature can reduce the efciency of the PV system.

● The inverter may produce moderate noise during operation. Please select installa-

tion location with care.

● Ensure legibility of the LEDs and the display (check read-off angle and installation

height).

● Although the unit is tted with UV resistant components, direct exposure to sunlight

should be avoided.

● Despite having an IP65 enclosure and being certied in accordance with soiling

category III, the unit must not be allowed to become heavily soiled.

7.3 Maintenance

Make sure that the device remains uncovered while in operation. To avoid the casing of
the solar inverter becoming soiled, it should be cleaned periodically.

User serviceable parts are not contained in the device. Under no circumstances should

the solar inverter be opened!

7.4 Installation

You should utilize the delivered mounting plate for problem-free installation of the solar
inverter. Installation to the wall should be implemented with the proper screws. Mount
the wall bracket so that the solar inverter only has to be simply attached. After that, the
device is to be bolted on securely.

Assembly instructions

1. Mount the mounting plate with appropriate screws (max. Ø 6mm) into at least four

of the eight holes to x the wall bracket in place. You can employ the mounting

plate as a template for marking the positions of the boreholes.

2. As the solar inverter weighs 21.5 kg, it should be lifted out of the transport crate by
at least two persons.

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

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 congured 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)

14

Operation and installation manual SOLIVIA 2.5 AP G3 TR

● 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 discon-

nected from the grid in case of a fault. The error message “PV+ grounding fault” or “PV­grounding 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” (EOE99000275). The grounding connection is monitored and should be
congured in the Setup menu (see „8.3.7 Submenu S (Setup)“, page 28).

Alternatively, it is possible to turn off the insulation- and grounding monitoring:

● ISO / GND OFF.

9. Diagnostics and data evaluation

9.1 Malfunctionrectication

The solar inverter is provided with an automatic diagnostics system which indepen-

dently identies certain faults and which can make them visible on the display.

Troubleshooting in the eld

In principle, it is always worth attempting a reset by reinitializing the solar inverter
whenever an error message appears on the display.

To reset the device, proceed as follows:

1. Isolate the solar inverter from the grid (open automatic circuit breaker).

2. Switch off the DC disconnector.

3. Wait: approx. 1 minute.

4. Switch DC disconnector back on.

5. Switch in grid (close automatic circuit breaker).

32

Operation and installation manual SOLIVIA 2.5 AP G3 TR

(In the eld, the rst step is to scan for potential fault causes that could be picked up by

the solar inverter and result in tripping.)

Various key parameters can be scanned via the display, thereby enabling conclusions
to be drawn about potential fault causes.

12. Glossary

AC

Abbreviation for „Alternating Current“.

Anti-islanding protection

This is a unit for grid monitoring with assigned switching elements (anti-islanding pro­tection) and is an automatic isolation point for small power generation systems (to 30
kWp).

CE

With the CE identication code, the manufacturer conrms the conformity of the product
with the valid EC Guideline and compliance with the signicant requirements stipulated

therein.

DC

Abbreviation for „Direct Current“.

EMC

The Electro-Magnetic Compatibility (EMC) concerns the technical and legal basics of

the mutual inuencing of electrical devices through electromagnetic elds caused by

them in electrical engineering.

Initialization

Under initialization (cf. English to initialize) is understood the part of the loading process

of a program, in which the storage space required for the execution (e.g. variable, code,

buffers ...) for the program is reserved and is lled with initial values.

Local utility company

By local utility company is meant a company which generates electrical energy and
distributes it over the public grid.

MPP

The Maximum Power Point is the point of the current-voltage diagram of a PV cell at
which the largest power can be tapped off, i.e. the point at which the product of current
and voltage has its maximum value.

Operation and installation manual SOLIVIA 2.5 AP G3 TR

Nominal power

Nominal power is the maximum permissible continuous power output indicated by the

manufacturer for a device or a system. Usually the device is also optimized so that the
efciency is at its maximum in case of operation with nominal power.

Nominal current

Nominal current is the absorbed current in case of electrical devices if the device is
supplied with the nominal voltage and yields its nominal power.

PE

In electric systems and cables a protective earth conductor is frequently employed. This
is also called grounding wire, protective grounding device, soil, grounding or PE (Eng­lish „protective earth“).

Photovoltaics (abbr.: PV)

The conversion of PV energy into electrical energy.

The name is composed of the component parts: Photos - the Greek word for light - and
Volta - after Alessandro Volta, a pioneer in electrical research.

Potential isolation

No conductive connection between two component parts.

Power dissipation

Power dissipation is designated as the difference between absorbed power and power
of a device or process yielded. Power dissipation is released mainly as heat.

PV cell

PV cells are large-surface photodiodes which convert light energy (generally sunlight)
into electrical energy. This comes about by utilization of the photoelectric effect (photo­voltaics).

PV generator

System comprising a number of PV modules.

42

PV module

Part of a PV generator; converts PV energy into electrical energy.

RJ45

Abbreviation for standardized eight-pole electrical connector connection. RJ stands for
Registered Jack (standardized socket).

RS485 (EIA485)

Differential voltage interface on which the genuine signal is transmitted on one core and
the negated (or negative) signal on the other core.

Separate grid system

Energy supply equipment which is completely independent of an interconnected grid.

Solar inverter

is an electrical device which converts DC direct voltage into AC voltage and/or direct
current into alternating current.

String

Designates a group of electrical PV modules switched in series.

String solar inverter (solar inverter concept)

The PV generator is divided up into individual strings which feed into the grid over
their own string solar inverters in each case. In this way, the installation is considerably
facilitated and the gain decrease, which can arise from the installation or from different
shading conditions of the PV modules, is considerably reduced.

TAB (2000)

The TAB 2000 are the technical regulations governing connection to the low-voltage
grid operated by distribution system operators in Germany. These Technischen
Anschlussbestimmungen or TAB for short have been in force since the year 2000. They

dene the requirements imposed by DSOs on the electrical systems operated by the

end customers of utility companies.
