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: Germany, France, Spain, Italy, Portugal, Greece, Czech Republic and Belgium. The solar inverter is characterized by its advanced housing design and state-of-the-art high-frequency 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 compliance with the specications of DIN VDE 0126-1-1, EN 50438, ENEL G.L. 12/2008, RD 1663, 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 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 (e.g. WEB´log); 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.

6 Operation and installation manual SOLIVIA 5.0 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 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 opencircuit 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 dustproof) 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 +60 °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 and DIN VDE 0126-1-1, EN 50438, ENEL G.L. 12/2008 and RD 1663 (anti-islanding protection). 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 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 systems of nominal 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. 12/2008 and RD 1663 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

6.5 Ambient temperature

The solar inverter can be operated in an ambient temperature between -25 °C to +60 °C. The following diagram illustrates how the power supplied by the solar inverter is reduced automatically 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 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 4.0 mm².

An automatic circuit breaker is to be provided in the line L upstream of every device, with a nominal current of 32 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 color 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 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.

The  rst line shows the actual low frequency limit and detection time settings according to the standards. Since the protection is not sensitive to the frequency variations less than 40 ms (two line cycles of the grid voltage at nominal frequency of 50 Hz), the detection time has been set to 60 ms. Pressing the test starts. Test starts also automatically after 1 minute if no is pressed.

If has been pressed the display shows, for example:

The limit “L:” will increase till crossing the actual measured grid voltage “A:”. Reached this condition the inverter display shows, for example:

L: 230 V 0.164 S A: 230 V UV pass

If the test is con rmed, the inverter performs the HFT test, high frequency test, which verify the high frequency protection. The display shows:

L: 50.30 Hz < 0.06 S Start HFT test?

L: 50.30 Hz HFT A: 49.99 Hz RUN

The limit “L:” will decrease till crossing the actual measured grid frequency “A:”. Reached this condition the inverter display shows, for example:

L: 49.99 Hz 0.044 S A: 49.99 Hz HF pass

If the test is con rmed, the inverter performs the LFT test, low frequency test, which verify the low frequency protection. The display shows:

L: 49.70 Hz < 0.06 S Start LFT test?

22 Operation and installation manual SOLIVIA 5.0 EU G3

If has been pressed the display shows, for example:

L: 49.70 Hz LFT A: 49.99 Hz RUN

The limit “L:” will increase till crossing the actual measured grid frequency “A:”. Reached this condition the inverter disconnects from grid and the display shows, for example:

L: 49.99 Hz 0.044 S A: 49.99 Hz LF pass

If the test is con rmed, the auto-test routine is  nished. The display shows, for example:

Autotest Passed Esc to continue

First line shows the actual auto-test status. If all the single test are passed and con rmed, the actual auto-test status will be passed. Pressing “ESC” the display goes back to the main menu.

If the actual auto-test status is failed, pressing “ESC” the display goes back to the main menu and the inverter is in error condition. The display shows “ AUTOTEST FAILED”. If the actual status is failed it’s possible to restart the auto-test routine. If the auto-test permanently fails please contact the customer service.

If during the auto-test is performed any grid or inverter errors occurs, the auto-test routine is aborted and the display shows the actual failed auto-test status. The inverter reset and perform a restart if the previous status was passed.

The auto-test can be started only if the inverter is in normal operating conditions. It is not possible to entry the auto-test routine if the grid is not in the de ned tolerances, if any internal inverter error occurs or the solar plan do not respect the speci cations.

A restart of the inverter will be done after the auto-test, when the result of the current auto-test is different from the result from the auto-test before.

While the auto-test routine is ongoing, green LED is  ashing, the red shows isolation measurement status and the yellow shows the status of last auto-test (yellow on: last auto-test was failed; yellow off: last auto-test was ok).
