Safety Precautions at the Machine Location

Ensure when installing machines with cooling-air vents that the cooling air can flow freely through the air vents without obstruction. Only operate the machine with the degree of protection specified on the rating plate.

Information on noise emission values

EMC device classifications

The inverter generates a maximum sound power level of <80 dB(A) (ref. 1pW) when operating under full load in accordance with IEC 62109-1.

The device is cooled as quietly as possible with the aid of an electronic temperature control system, and depends on the amount of converted power, the ambient temperature, the level of soiling of the device, etc.

It is not possible to provide a workplace-related emission value for this device because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of the room in general.

Devices with emission class A:

- are only designed for use in an industrial setting

- can cause conducted and emitted interference in other areas.

Devices with emission class B:

- satisfy the emissions criteria for residential and industrial areas. This also applies to residential areas in which power is supplied from the public low-voltage grid.

EMC device classification as per the rating plate or technical specifications

EMC measures In certain cases, even though a device complies with the standard limit

values for emissions, it may affect the application area for which it was designed (e.g. when there is sensitive equipment at the same location, or if the site where the device is installed is close to either radio or television receivers). If this is the case, then the operator is obliged to take appropriate action to rectify the situation.

Mains connection

High-performance devices (> 16 A) can affect the voltage quality on the mains network because they can feed powerful current into the main supply. This may affect a number of types of device in terms of:

- connection restrictions

- criteria with regard to maximum permissible mains impedance

- criteria with regard to minimum short-circuit power requirement

at the interface with the public mains network

see Technical Data

In this case, the plant operator or the person using the device should check whether or not the device is allowed to be connected, where appropriate through discussion with the power supply company.

Safety of persons

Safety

Housing unit

Galvanic insulation

Warning! Incorrect operation and work performed incorrectly can

cause serious injury & damage! Only qualified staff are authorized to put your FRONIUS IG unit into operation and only within the scope of the respective technical regulations. Do not start operation or carry out maintenance works before you have read the chapter „Safety Conditions“!

Only qualified installers are authorized to open the connection area.

Opening the connection area is only permitted when it is not under voltage.

The separately insulation encased power stage shall only be opened when not under voltage and only by Fronius-trained service staff.

The design and function of the FRONIUS IG unit offer a maximum of safety, both during installation as well as in operation. A complete galvanic insulation between DC and AC side guarantees maximum safety.

Monitoring the electrical mains network

The FRONIUS IG takes over the tasks of galvanic insulation and network monitoring. The passive and active measures for the protection of persons and equipment are understood by this.

Whenever conditions in the electric mains network are inconsistent with standard conditions (for example mains switch-off, interruption), your FRONIUS IG unit will immediately stop operating and interrupt the supply of power into the mains.

Your FRONIUS IG unit can monitor the situation in the mains in several ways, by

- monitoring voltage

- monitoring cycle frequency

- ENS (optional)

The ENS option is compulsory in only a few countries, and only for them the FRONIUS IG unit is available with this option. In any case however will the monitoring and safety systems integrated in the FRONIUS IG unit be available as standard equipment.

Monitoring the electric mains network

(continued)

The permanent ENS mains monitoring scheme is an additional link in its safety chain. One of the signs by which ENS identifies abnormal situations in the mains is a sudden increase of the impedance in the mains network.

Photovoltaic generator

Both the permanent mains monitoring by your FRONIUS IG unit directly as well as ENS make sure that in case of a mains blackout (due to being switched off by the utility company or due to a defect in the transmission line) it stops feeding power into the mains.

This scheme definitely prevents dangerous voltages at the AC lines and constitutes an essential contribution towards avoiding hazards for the maintenance staff.

Before connecting the solar modules, you must check whether the voltage parameters laid down in the manufacturer’s data correspond with reality.

When checking the voltage reading, please take into account that solar modules supply a higher no-load voltage when temperatures are low and insolation remains unchanged.

At an outside temperature of -10 degrees centigrade the no-load voltage of the solar modules must in no case exceed 500 V - or 530 V for the IG 60 HV. The data sheet of the solar module will tell you the temperature factors applicable for ascertaining the theoretical no-load voltage at -10 degrees centigrade.

ENEN

Mains connection

DC plugs

AC plugs

In case the solar modules exceed a no-load voltage of 500 V - or 530 V for the IG 60 HV - the FRONIUS IG unit will be completely damaged and all warranty rights will cease to exist.

Only a licenced electricity installer is authorized to carry out the connection works to the public mains network.

Note! If DC plugs are provided, they must never be disconnected from the sockets of the solar modules as long as the FRONIUS IG unit is feeding power into the mains. Before disconnecting the DC plug you must always disconnect in the fuse for the house distribution.

Note! Disconnect AC plug connections only when the equipment is not under voltage, after having disconnected the fuse for the inhouse distribution panel.

The Safety Concept

Standards and Regulations

Your FRONIUS IG unit complies with all applicable standards and regulations.

They comprise in particular:

- Guideline 89/336/EEC electromagnetic compatibility

- Guideline 93/68/EEC CE-marking

- European standards EN 50 081-1, EN 50 082-2, EN 61 000-3-2

- „Guideline for parallel operation of self-owned photovoltaic generating systems with the low voltage mains network of the utility supply company“, issued by the Association of German Electric Utility Supply Companies (VDEW)

- „Technical Guidelines for parallel operation of self-owned photovoltaic generating systems with the low voltage mains network of the utility supply company“, issued by the Association of Electric Utility Supply Companies of Austria

- „Safety requirements for photovoltaic energy generation plants“ (ÖNORM/ÖVE E2750), to the extent that these regulations are applicable for the inverter.

Conformity Declaration

The respective conformity declarations you will find in the appendix to these operating instructions.

General Introduction

How a photovoltaic system works

ENEN

General information

Your roof is your power generator

The energy from worldwide insolation amounts to a total of about 1,540,000,000,000,000,000 kWh/year (1,540 Peta kWh/year). This is

15.000 times as much as the electricity consumption worldwide. We

congratulate you on your decision to actively use world’s biggest energy pool. By the way, it was a scientist in the field of of physics, AlexandreEdmond Bequerel, who first discovered the photo-voltaic effect in 1839. The name photo-voltaic comes from the driving force behind this technology, which is the ray of light. The ray of light consists of unimaginably tiny particles, the photons.

Let us simply start our explanation with a straight silicon solar cell. Remembering our physics class in school, we know that there are four electrons in the outside electron shell of a silicon atom arranged around its atomic nucleus, they are the so-called peripheral valency electrons. The sunlight’s photons enter the solar cells and concentrate energy in the valency electrons. The electron eventually separates from the silicon atom and leaves behind it an atom with a positive charge.

So that the free electrons will flow in one direction and thus generate electricity, the poles on the front and back side of the cell must be different from each other.

The silicon atoms of the front must be packed with a slight quantity of phosphor atoms which contain an additional valency electron. On the back of the cell, atoms of boron having only three valency electrons are added to the silicon atoms.

The result is an imbalance which makes the electrons flow, and this is how electric power is generated.

Many such solar cells united together and packed behind glass form one of your solar modules.

Your roof is your power generator

Power output and voltage are increased by combining a number of solar cells. If solar modules are connected in series like on a string,

solar modules connected parallel and in series is called solar generator.

The direct current generated in the solar modules can be fed into the public mains network or put to home use after having been transformed in an inverter. This is the basic purpose of your FRONIUS IG unit.

The FRONIUS IG Unit in the Photovoltaic System

General information

Transforming DC into AC electricity

Fully automatic operation management

Your FRONIUS IG unit is the latest generation of solar inverters. It is the highly complex link between solar modules and the public electricity mains network.

As such it is in charge of a number of highly qualified tasks.

The FRONIUS IG unit transforms the direct current generated by the solar modules into alternating current. This alternating current is fed into your home system or into the public mains synchronically with the voltage which is used there. The FRONIUS IG has been designed exclusively for use in mains connected photovoltaic schemes. It cannot generate electric power independent from the public mains network.

The operation of the FRONIUS IG unit is fully automatic. Starting with sunrise, as soon as the solar modules generate enough power, the automatic control unit starts monitoring voltage and frequency. As soon as there is a sufficient level of insolation, your solar inverter starts supplying and feeding power. A few Watts of solar power output are sufficient to achieve this, depending on which version the unit is!

ENEN

Voltage transformation and galvanic insulation

The operation of the FRONIUS IG unit ensures that at any time the maximum possible power output is drawn from the solar modules.

This function is called MPPT (Maximum Power Point Tracking). It operates with extremely high precision. As dusk starts there is no more sufficient energy available to feed power into the mains, the FRONIUS IG unit shuts the mains connection completely and stops operating. All settings and data recorded are of course saved.

The FRONIUS IG has been designed for use with solar modules of a wide range of input voltages. This allows the use of the greatest variety of types of solar modules. Important notice: the parameters indicated for maximum DC voltage (total voltage of the solar cells connected) must at no time be exceeded!

By its design and operation, the FRONIUS IG offers a maximum of safety during installation as well as in operation.

Voltage transformation and galvanic insulation

(continued)

The FRONIUS IG is equipped with an HF-transformer (HF = high frequency) which assures a galvanic insulation between the DC side and the mains. In addition, the HF principle results in a drastic reduction of the transformer’s size, which means that it requires less space and has considerably less weight. In spite of its full galvanic insulation, the FRONIUS IG unit achieves a high degree of efficiency, due to its innovative circuit schemes.

Monitoring the mains network

The FRONIUS IG unit is in charge of monitoring the mains network. This responsibility comprises all measures necessary for the protection of persons and machines in case of a power blackout.

The FRONIUS IG unit is programmed to stop operation immediately and stop supplying power whenever conditions in the mains network deviate from standard (for example when power is switched off or in case of any other kind of interruption).

There are several ways how the FRONIUS IG unit can identify a mainscutoff, it can do so for example by monitoring:

- voltage

- frequency

- resistance (only FRONIUS IG with ENS)

For this purpose it is important that the specific monitoring procedures applicable for the respective countries are carried out directly by the FRONIUS IG unit without the use of additional electronic monitoring devices. This will result in a substantial reduction of the installation work and cost.

Display function and data communication

The complex technical systems of innovative solar inverters make it necessary to design the display which is the interface with the user very carefully. It is an unwavering design aiming at ease of operation and permanent availability of the system’s data.

The FRONIUS IG unit is equipped with a basic recording function for monitoring minimum and maximum data on a daily and a cumulative basis directly from the display. There is also an option to allow the reading of the following weather data on the display:

- two different temperature readings (for example temperature at the solar modules as well as the outside temperature in the shade)

- insolation

In additition to the functions installed in the FRONIUS IG unit, a wide choice of elements offered for data communication allows for many possibilities of recording and visualising data. The respective components required to upgrade the system are easy to install using the FRONIUS IG DatCom operating instructions. The installation of system upgrades, such as DatCom components, allows for possible remote system monitoring

Display function and data communication

(continued)

via modem, text messages to mobile phones in the event of faults, data visualisation and data comparison on the PC.

ENEN

Your advantage

With each additional task, as described above and controlled directly by the inverter, installation becomes easier and less costly because no additional peripheral equipment will be required. Based on our experience and the use of the most innovative technologies, the FRONIUS IG unit is able to manage all these tasks simultaneously.

In addition, the FRONIUS IG unit complies with a whole number of requirements established for the safety of people and other household appliances, as well for its own safety.

Some of these requirements are:

- ability to monitor the mains network

- the quality of the electricity supplied

- detection of outside disturbance and interference (for example mobile telephones).

Annexed you will find the respective certificates.

Product description

The FRONIUS IG Unit

How it functions

The FRONIUS IG unit is designed for fully automatic operation. Basically no personal control is necessary for feeding the power it generates into the mains network.

The FRONIUS IG unit starts operating automatically as soon as the solar modules produce sufficient power output after sunrise. From this point onwards, you will also receive system information from the FRONIUS AG graphic display.

During its operation the FRONIUS IG unit maintains the voltage of the solar modules at any time within the range of optimal power withdrawal.

- the optimal voltage for any particular status of operation of the solar modules is called MPP voltage (MPP = maximum power point)

- exactly maintaining the MPP voltage guarantees an optimal level of the efficiency factor of your solar modules at any time (MPP-tracking).

As soon as dusk begins there is no more sufficient energy available to feed into the mains network, the FRONIUS IG unit fully shuts off the mains connection.

- during the night the FRONIUS IG unit does not draw any energy from the public mains

- the data and parameters set remain available

- it is also possible to shut the unit off manually

Startup phase

After having switched on automatically, the FRONIUS IG unit goes through a self-test, and after that through a test of the public mains network.

This test takes between only few seconds up to several minutes, depending on the regulations in your country. During startup the LED illumination is yellow.

(1) Segment test

- all display elements light up for about one second

(2) TEST

- self test of important components of the FRONIUS IG unit

- as long as the photovoltaic equipment is operating without fault

- and an additional message is displayed on the screen

Note! A message appears for example if there is an insulation fault, which however does not affect the function of the FRONIUS IG. However for safety reasons we recommend that the insulation fault is remedied as soon as possible. Depending on the country setup, the inverter can also disconnect from the public grid when there is an insulation error and stop feeding energy into the grid.

The FRONIUS IG with display shows a status message. A message is displayed in the FRONIUS IG.access software for the FRONIUS IG without display.

If a message (e.g. „502“, Section „Status diagnosis and remedy) is shown, rectify the relevant status and acknowledge this by pressing the „Enter“ button.

The Display

General information

Functions of the keys

The FRONIUS IG unit is pre-configured to be ready for operation, therefore it is not necessary to make any adjustments in order to be able to get it to operate fully automatic and feed power into the mains.

The display is powered by the solar module and is therefore available throughout the day.

Important! The display of the FRONIUS IG is not a calibrated measuring device. A slight deviation by a few percent is inherent in the system. Therefore, a calibrated meter is required for accurate settlement of data with the electricity supply company.

(continued)

module voltage... voltage in the solar modules at the moment of data display

The voltage indicated during power supply into mains is equal to the socalled MPP voltage (MPP = maximum power point). The FRONIUS IG unit keeps the module voltage always within the maximum possible power output withdrawal from the solar modules. This always guarantees an optimum efficiency performance of your photovoltaic generator..

module power ... power supplied by solar modules at the moment of data display (Ampere)

The FRONIUS IG unit keeps the module voltage always within the range of the maximum possible power withdrawal from the solar modules. This results in the optimum for the module electricity.

* module temperature ... tem-

perature at solar modules (degrees centigrade; can also be set for degrees Fahrenheit; temperature sensor No.1; sensor card optional)

isolation resistance of photovoltaic generator (MOhm)

Isolation resistance is the resistance between the positive pole or the minus pole of the photovoltaic generator and the grounding potential. Whenever an isolation resistance higher than 500 kOhm is shown, the photovoltaic generator is sufficiently insulated.

Warning! An isolation resistance < 500 kOhm can be caused by an insufficiently insulated DC cable or by defective solar modules. In case of an insufficient isolation resistance you must in any case contact your Fronius service partner.

Important! Only an isolation resistance of less than 500 kOhm indicates that there is an error. Whenever a higher insulation reistance is shown it is not to be interpreted as an error.

Whenever there is an isolation resistance of less than 10 MOhm, the display differentiates between the negative potential and the earthing (minus sign „-“) and the positive potential and the earthing (plus sign „+“)

Additional information

Upgrading the system

The FRONIUS IG unit is prepared for a whole series of system upgrades, such as:

- for communicating between FRONIUS IG and outside system extensions, for example with other FRONIUS IG units

- Data logger (for recording and managing data from your photovoltaic system by PC) including datalogger and modem connection

- Various large displays (FRONIUS IG Public Display)

- Actuators / Relays / Alarm (FRONIUS IG Signal Card)

- Sensors (Thermo sensors / Irradiance / Metering)

The system upgrades are offered in slot-in boards, similar to those on your personal computer.

ENEN

For increased flexibility, all upgradings are also available in a version with external housing

For an unlimited individual use of system upgradings, Fronius has developed the LocalNet. LocalNet is a data network which allows linking more than one FRONIUS IG units with the system upgrade elements.

LocalNet is a bus system. One single cable is sufficient to allow communication between one or several FRONIUS IG units with all system upgrade elements. This reduces the cable requirement to a minimum.

Upgrading the system

(continued)

Please take further details from the chapter „LocalNet“ of the installation and service manual.

Forced ventilation

The FRONIUS IG unit is equipped with a temperature and rotation controlled air circulator which provides for the following features:

- smaller heat sinks - more compact housing

- components are better cooled - efficiency increases / longer life

- least possible energy consumption / noise level, due to rotation control and ball bearing support

- should there not be sufficient heat discharge in spite of maximum rotation of the ventilator (for example no adequate heat transfer away from the control panels) the power will be derated for auto-protection of the FRONIUS IG unit.

- derating the power reduces the output of the FRONIUS IG unit for a short period sufficient to ensure that the temperature will not exceed the admissible parameter.

- your FRONIUS IG unit will remain ready for operation as long as possible without any interruption.

- Even if the FRONIUS IG is frequently used at full load the fan can be expected to last approx. 20 years.

Installation

Choosing the location general

Make the best possible use of your FRONUS IG unit by additionally observing the following conditions:

- mains impedance should not be unnecessarily increased by a too narrow AC conductor cable cross section between the FRONIUS IG unit and the in-house distribution panel. The AC conductor cable resistance between the FRONIUS IG unit and the house distribution panel must not exceed 0,5 Ohm.

- install it only on a solid vertical wall

- The ambient temperature should not be under minus 20 degrees or over 50 degrees centigrade.

- No objects must be located within a distance of 15 cm around the air vents on both sides of the FRONIUS IG unit

- Keep a lateral distance of 20 cm between individual FRONIUS IG units.

- The air flow direction within the inverter is from left to right (cold air intake left, hot air exit right).

- When installing the FRONIUS IG unit in a switch panel cabinet (or similar closed sections) it is necessary to make sure that the hot air which develops will be discharged by forced ventilation.

Choosing the location indoor housing

The FRONIUS IG unit can only be installed inside buildings or on outside locations provided that they are protected from rain or snow.

- During certain operation phases the FRONIUS IG unit may develop a slight noise level, for this reason it should not be installed in the immediate vicinity of living areas

- the FRONIUS IG unit is not to be set up in areas where there is heavy dust development

- the FRONIUS IG unit is not to be set up in areas where there is heavy incidence of conducting dust particles (for example iron filings)

- the FRONIUS IG unit is to be installed at a height which keeps the display slightly below the position of your eyes in order to secure best possible readability of the display.

- The distance between the top edge of the FRONIUS IG and the ceiling should be approx. 30 cm.

Do not install the inverter in:

- areas with large amounts of dust

- areas with large amounts of conducting dust particles (e.g., iron filings)

- areas with corrosive gases, acids or salts

- areas where there is an increased risk of accidents, e.g., from farm animals (horses, cattle, sheep, pigs, etc.)

- stables or adjoining areas

ENEN

Choosing the location outdoor housing

- The IP 45 protection system means that the FRONIUS IG can be exposed to moisture. However we recommend if possible that direct moisture is avoided.

- In spite of the IP 45 protection system the FRONIUS IG Outdoors should if possible not be exposed to the effects of the sun as there is no display film worldwide that is resistant to UV-Rays over a period of time. However to achieve a long life the FRONIUS IG Outdoors has an exterior casing and a display with a cover slide.

- The protection of the display unit provided by the cover slide also increases the life of the film. (The ideal situation is choosing a partially protected fitting position for the FRONIUS IG Outdoors with exterior casing e.g. in the area of the solar module, or under a projecting roof).

- FRONIUS IG can be installed vertically as well as horizontally - according to chapter „Fixing the wall mounting for FRONIUS IG Outdoors“.

- For use in environments with heavy dust development: If necessary remove the fan plates and clean the integrated fly screen

Do not install the inverter:

- where it can be exposed to ammonia, corrosive gasses, acids or salts (e.g., fertilizer storage areas, vent openings of livestock stables, chemical plants, tanneries)

Connection

Connection to the Solar Modules and to the Public Mains

Solar modules

Mains network monitoring

The following points are important for the most economic use of the FRONIUS IG unit when choosing suitable solar modules:

- the no-load voltage increases when temperature decreases with insolation remaining unchanged. Therefore the no-load voltage must not exceed 500 V - or 530 V for the IG 60 HV.

Whenever the no-load voltage of the solar modules exceeds 500 V - or 530 V for the IG 60 HV - the FRONIUS IG unit will be destroyed, and all warranty rights will become null and void.

- More exact data for dimensioning the solar modules for the location chosen can be obtained using calculation schemes such as the FRONIUS configurator (available on www.fronius.com).

As your FRONIUS IG unit need be connected to only one phase of the mains network, in can be installed in almost any part of the house.

Warning! In order to ensure the best possible functioning of the mains monitoring system, it is important to make sure that there is a minimum of resistance in the feeding lines to the connection point. The AC conductor resistance between the FRONIUS IG unit and the house distribution panel must not exceed 0,5 Ohm.

Schemes with more than one inverter

Warning! Hazard due to supply voltage and DC-voltage from the

solar modules. Only licenced electricity installers are authorized to open the connection area and only provided that it is not under voltage.

For larger photovoltaic schemes it is possible to connect several FRONIUS IG units in parallel without any problems.

In order to secure a symmetric feed-in of the power supply, the FRONIUS IG units should be connected evenly to all 3 phases. If you have any doubt you should approach your specialized dealer whenever there are technical problems.

AC-side overcurrent protection

Important! We recommend the following for AC-side overcurrent protec-

tion:

- A separate 16 A fuse for each Fronius IG 15 and 30

- A separate 25 A fuse for each Fronius IG 40 and 60

- Alternative for Fronius IG 40 and 60: 32 A automatic circuit breaker, type „C“

Note! A residual current circuit breaker for the AC connecting cable may be required depending on local regulations, the power supply company as well as other conditions. A type A residual current circuit breaker is generally sufficient in this case. However, false alarms can be triggered for the residual current circuit breaker in individual cases and depending on local conditions. For this reason, Fronius recommends that you use a residual current circuit breaker suitable for a frequency converter. The residual current circuit breaker for each individual inverter must have a rated current of at least 30 mA.

Status diagnosis and repair

Service-Codes Displayed

Service display

General service codes

Your FRONIUS IG unit is equipped with a self diagnostic system which automatically identifies a large number of possible defects by itself and displays them on the screen. It is thus possible to quickly ascertain defects in the FRONIUS IG unit, in the photovoltaic system as well as installation and operation errors.

Whenever the self diagnostic system has identified a particular defect, the respective service code is displayed on the screen.

Note! Display of a service code for a short time may be a result of the control procedure of your FRONIUS IG unit. If subsequently it continues to operate normally, there has not been a case of an error.

As long as the no load voltage of the solar modules is not sufficient, the screen displays the information „DC

LOW

“.

As soon as the no-load voltage exceeds 150 V, the FRONIUS IG unit starts synchronizing the network (display shows „SYNCAC“).

As long as the power output at the solar modules is insufficient, the display shows the message „POWER

After a short time of waiting the FRONIUS IG resumes network synchronization (message: „SYNCAC“).

LOW

“.

Complete failure

Should the display remain dark for a longer period of time after sunrise you must check the no-load voltage of the solar modules.

Should the no-load voltage of the modules (at the connecting points of the FRONIUS IG UNIT) not reach 160 V, it is possibly the case of a defect in the remaining part of the photovoltaic system.

If the no-load voltage of the solar modules (at the connection points of the FRONIUS IG unit) amounts to more than 160 V, there may be a basic defect in the FRONIUS IG unit. In this case you must consult a Fronius trained service technician.

Our product complies with the following standards and regulations

The FRONIUS IG unit complies with the „Regulation for supply and parallel operation of low voltage network power generation systems for owner’s own use“ (Richtlinie für Anschluß und Parallelbetrieb von Eigenerzeugungsanlagen am Niederspannungsnetz) of VDEW, the German Association of Producers of Electric Energy (Verband der Elektrizitätswirtschaft).

In addition, all prerequisites of the applicable standards as well as regulations within the scope of the applicable EU (European Union)regulation are complied with, so that all equipment bears the CE label.

In countries with applicable regulations the FRONIUS IG unit is equipped with a circuit element to prevent isolated operation, as officially accepted by the German professional association „Berufsgenossenschaft für Feinmechanik und Elektrotechnik“ (professional association for precision mechanics and electricity technology) in accordance with the German standard DIN VDE 0126. This so-called ENS device is based on the principle of impedance monitoring (for of product reliability confirmation document see annex).

In the particular country versions both with as well as without ENS the monitoring and safety systems integrated in the FRONIUS IG as part of its standard equipment make sure that in case of a mains dropout (caused either by shutoff effected by the utility supplier or by power transmission line failure) the power supply feeding will be immediately interrupted.

In particular, the following standards and regulations are being complied with:

ENEN

- EN 61000-3-2 (harmonic oscillations), EN 61000-6-2, EN 61000-6-3

- EN 6100-6-3 (EMV-interference emissions)

- EN 6100-6-2 (EMV-interference immunity)

- EN 50178 (electric safety)

- E DIN VDE 0126 (ENS:country versions with standard ENS card)

- Regulation 2004/108/EC electromagnetic compatibility

- Regulation 93/68/EECCE marking

- „Regulation for photovoltaic generation plants in parallel operation with the low voltage mains network of the utility electricity companies“, issued by VDEW, the Association of German Electric Utility Supply Companies (Vereinigung Deutscher Elektrizitätswerke).

- „Technical regulations for photovoltaic plants in parallel operation with the low voltage mains network of the electric utility companies“, issued by the Association of Electric Utility Companies of Austria (Verband der E-Werke Österreichs)

- Safety requirements for photovoltaic energy generation plants (Austrian standard ÖNORM/ÖVE E2750), as far as these regulations are applicable for the inverter.

This is the guarantee for an unproblematic and unbureaucratic authorization of operation by the distribution network operator and the electric utility supply company (for confirmity declaration documents see annex)
