IMPORTANT SAFETY INSTRUC-

TIONS - SAVE THESE INSTRUC-

TIONS

General Warning! Incorrect operation and work performed incorrectly can cause serious injury & damage!

Only qualified staff are authorized to install your FRONIUS IG and only within the scope of the respective technical regulations. Do not start operation or carry out maintenance work before you have read the chapter “Safety Regulations“!

This manual contains important instructions for the FRONIUS IG

2000, 3000, 2500-LV, 4000, 5100, 4500-LV that shall be followed during installation and maintenance of the inverters.

Warning! These servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not perform any servicing other than that specified in the operating instructions unless you are qualified to do so.

Electrical installations must be made in accordance with the National

Electrical Code, ANSI/NFPA 70, and any other codes and regulations applicable to the installation site.

To reduce the risk of fire, do not connect multiwire branch circuits to an AC load center (circuit breaker panel).

Housing Only qualified installers are authorized to open the connection area.

Do not open the connection area when the inverter is under voltage.

Only Fronius-trained service staff may open the upper portion (power stage) of the inverter, and only when it is not under voltage.

Galvanic isolation

The design and function of the FRONIUS IG unit offers a maximum level of safety, both during installation as well as in operation. A complete galvanic isolation between the DC and AC sides is one such safety feature.

The FRONIUS IG provides galvanic isolation and grid monitoring.

The passive and active measures for the protection of persons and equipment help ensure safe installation and operation.

Monitoring the grid

Whenever conditions in the electric grid are inconsistent with standard conditions (for example grid switch-off, interruption, etc.), your

FRONIUS IG unit will immediately stop operating and interrupt the supply of power into the grid.

Your FRONIUS IG unit determines the grid’s status by:

- monitoring voltage

- monitoring frequency

- monitoring islanding conditions

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

Repair Only FRONIUS service staff are authorized to carry out repairs to the

FRONIUS IG unit.

Solar modules

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

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

At 14 °F (-10 °C) the open-circuit voltage of the solar modules must never exceed 500 V. The data sheet of the solar module will tell you the temperature factors applicable for ascertaining the theoretical open-circuit voltage at 14 °F (-10 °C).

If the solar modules exceed an open-circuit voltage of 500 V, the

FRONIUS IG unit might be damaged and all warranty rights will be voided.

5

Solar modules

(continued)

The FRONIUS IG includes a ground fault detector interruptor (GFDI) according to UL 1741. This device measures the ground current of the PV array and prevents the inverter from feeding the grid in case of a ground fault.

Grid connection

Only appropriately licensed contractors are authorized to connect your FRONIUS IG to the grid. Consult your local authorities for specific requirements.

Before connecting the FRONIUS IG to the grid, permission for the connection must be granted by the utility company.

Standards and Regulations

Your FRONIUS IG unit complies with the requirements for "Inverters, converters and controllers for use in independent power systems"

UL1741. The ground-fault detection and interruption is in compliance with NEC 690 building code requirements.

Product listings and compliance

The respective conformity declarations can be found in the appendix to these operating instructions.

How a photovoltaic system works

General information

The energy from worldwide sunlight 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 resource. The word "photovoltaic" comes from the driving force behind this technology, which is light. When light strikes photovoltaic cells, a voltage and current is created.

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, both the output power as well as the voltage will increase.

+

+ mod. 1 mod. 1 mod. 2 mod. n mod. 2 mod. n

-

total array current = current string 1 + 2, ... n

In a parallel connection of several such strings the output power and the output current will increase, while the voltage will remain unchanged (see right picture). The combination of all solar modules connected in series and parallel is called a solar array.

Electricity is converted under the roof

The direct current generated in the solar modules can only be fed into the grid or used in your home after having been transformed by an inverter.

This is the basic purpose of your FRONIUS IG unit.

Operation manual

The FRONIUS IG Unit in the PV System

General information

The FRONIUS IG is the latest generation of solar inverter. It is the highly complex link between solar modules and the grid.

As such it is responsible for a number of high-level tasks. The following diagram gives a graphical overview as to where the FRONIUS

IG is placed in the PV system.

PV array

FRONIUS IG

Main AC

Load

Center

Energymeter

Converting

DC into AC current

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 grid and synchronized with the voltage that is used there. The FRONIUS IG has been designed exclusively for use in grid connected photovoltaic systems. It cannot generate electric power independent from the grid.

8

Fully automatic operation management

The FRONIUS IG is fully automatic. Starting at 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 feeding energy to the grid. A few Watts of solar power output are sufficient to achieve this.

The control system of the FRONIUS IG unit ensures that the maximum possible power output is drawn from the solar modules at all times.

This function is called MPPT (Maximum Power Point Tracking). It operates with extremely high precision. As dusk starts and there is no longer sufficient energy available to feed power into the grid, the

FRONIUS IG unit shuts down the grid connection completely and stops operating. All settings and data recorded are saved.

Voltage transformation and galvanic isolation

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 modules connected) must at no time be exceeded!

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

The FRONIUS IG is equipped with an HF-transformer (HF = high frequency) that ensures galvanic isolation between the DC side and the grid. 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. The FRONIUS IG unit achieves a high degree of efficiency due to its innovative circuit schemes.

Monitoring the grid

The FRONIUS IG unit monitors the grid. This responsibility comprises all measures necessary for the protection of persons and machines in case of a power blackout or other grid loss.

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

9

Monitoring the grid

(continued)

There are several ways the FRONIUS IG unit can identify a gridcutoff, by monitoring:

- voltage

- frequency

- islanding conditions

Display function and data communication

The FRONIUS IG unit comes standard with a display that has been designed to enable quick and easy access to the most important data in your PV system.

The FRONIUS IG is equipped with a basic logging function to monitor minimum and maximum data on a daily and a cumulative basis.

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)

- irradiance

In addition to the functions installed in the FRONIUS IG unit, a wide choice of data communication products allows for many possibilities of recording and visualizing data. The respective components required to upgrade the system are easy to install.

Your advantage

With each additional parameter, that is 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 FRONI-

US IG unit is able to manage all system parameters simultaneously.

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

Some of these requirements are:

- ability to monitor the grid

- the quality of the electricity supplied

- immunity from outside disturbance and interference (for example, from mobile telephones).

10

Product description

The FRONIUS IG Unit

How it functions

The FRONIUS IG unit is designed for fully automatic operation. No manual control is necessary for feeding the power it generates into the grid.

The FRONIUS IG unit starts operating automatically as soon as the power output of the solar modules is sufficient after sunrise.

During its operation the FRONIUS IG unit optimizes the voltage of the solar modules for maximum power output.

- the optimal voltage for any particular solar module is called MPP voltage (MPP = maximum power point)

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

As soon as dusk begins there is no longer sufficient energy available to feed into the grid. The FRONIUS IG unit fully shuts off the grid connection at this time.

- during the night the FRONIUS IG unit draws less than 150 mW from the grid

- the data and parameters are saved

- it is also possible to shut the unit off manually

Startup phase

After switching on automatically, the FRONIUS IG unit goes through a self-test, then through a thorough test of the grid. This test takes five minutes. During startup the LED illumination is yellow.

Additional information

Upgrading the system

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

- Communication between FRONIUS IG and DatCom units

- Dataloggers (for recording and managing your photovoltaic system data via personal computer), including Datalogger and modem connection

- Sensors (temperature sensor / irradiance / electricity consumption meter / ...)

Some system upgrades are offered as plug-in cards, similar to those on your personal computer.

Other system upgrades are offered in external housings

For unlimited system upgradeability, Fronius has developed the

LocalNet. LocalNet is a data network that allows linking multiple

FRONIUS IG units with data communication components.

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.

39

Upgrading the system

(continued)

Please see further information in the chapter "LocalNet" of the installation and service manual.

Forced ventilation

The FRONIUS IG unit is equipped with a temperature controlled, variable speed fan that provides the following features:

- more compact housing - as a result of smaller heat sinks

- components are better cooled - efficiency increases / longer life

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

- should there be insufficient heat dissipation in spite of the fan operating at maximum speed (for example inadequate heat transfer away from the heat sinks) 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.

Installation manual

Installation

Installation instructions

These installation instructions serve as a manual for qualified electrical professionals and detail the installation, initial operation, status diagnosis and repair processes. It is in your interest to read the operating instructions carefully and to thoroughly observe the instructions it contains. In doing so you will avoid malfunctions resulting from incorrect operation.

Safety

Warning! Work performed incorrectly can cause serious injury and damage.

Read the installation instructions carefully before installing the

FRONIUS IG.

Only a qualified electrical professional is authorized to carry out the installation of the FRONIUS IG.

General information

Your FRONIUS IG is the latest generation of solar inverter. It is the highly complex link between your solar modules and the grid. As such, it is in charge of a number of highly technical tasks. The following diagram should give you a brief overview of a PV system including a FRONIUS IG.

Choosing the location general

To get the most out of your FRONUS IG unit, observe the following rules:

- Limit grid impedance by using an appropriately-sized AC conductor 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 should not exceed 0.5 Ohm. This can be achieved by using the following cable-sizes (according to NEC handbook, chapter 9, table 8):

- AWG 10: maximum 200 ft. (60 m)

- AWG 12: maximum 126 ft. (38 m)

- Only install it on a solid vertical wall at a minimum of 3 ft. (0.9 m) above the ground and to a maximum of 6.5 ft. (2 m)

- The ambient temperature should not be below -4 °F (-20 °C) or over

122 °F (50 °C).

- No objects are to be located within a distance of 6 in. around the air vents on both sides of the FRONIUS IG unit.

- When installing more than one unit, keep a distance of 8 in. between each FRONIUS IG.

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

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

Choosing the location

- during certain operation phases the FRONIUS IG unit may produce a slight noise. For this reason it should not be installed in an occupied living area

- the FRONIUS IG unit is not to be set up in areas with large amounts of dust. If unavoidable, place the FRONIUS IG in an appropriately rated and ventilated box.

- the FRONIUS IG unit is not to be set up in areas with large amount of conducting dust particles (for example iron filings)

- the FRONIUS IG unit is to be installed at a height that keeps the display slightly below eye level for best possible readability of the display.

- NEMA 3R protection means that the FRONIUS IG can be exposed to moisture. However, we recommend that direct moisture be avoided, if possible.

- In spite of the NEMA 3R protection system, the FRONIUS IG should not be exposed to direct sunlight, as this could result in temperature derating.

43

Preparing the wall mounting

In the following it is described how the FRONIUS IG is mounted to the wall. As your FRONIUS IG is delivered, the mounting plate is fixed to the inverter by two screws on the bottom of the FRONIUS IG.

For mounting the inverter to the wall proceed as follows:

- Loosen the screws (1) on the bottom of the inverter and remove the mounting plate (2)

- Fix the mounting plate (2) to the wall using four suitable dowels (3) and screws (4)

(2)

(4) (3)

(4) (3)

(4) (3)

(4) (3)

(1)

Important! Due to the variety of dowels (3) and screws (4) available for the various types of wall surfaces, these are not included.

In most cases, you should use 1/4 in. or 5/16 in. stainless steel or aluminium screws capable of supporting 26 lbs (FRONIUS IG 2000, 3000 and

2500-LV) or 42 lbs (FRONIUS IG 4000, 5100 and 4500-LV) of inverter weight. Triangulate the positions of these on the mounting plate using the pre-drilles holes when possible. Three vertically aligned holes for single stud mounting will suit most installations.

Caution! The FRONIUS IG may become dislodged and fall from the mounting plate if the unit is not fixed to the mounting plate using the two screws at the bottom (that were removed at the beginning).

Note! If you modify the FRONIUS IG enclosure with custom openings you will be required to return the unit for repair in the event of a warranty-related issue rather than doing an inverter exchange.

- Slide the FRONIUS IG from above so that the unit may hang from the top of the mounting plate (2)

- Attach the FRONIUS IG to the bottom of the mounting plate (2) by using the screws (1) that were removed before

44

Connection

Safety

General

Warning! Hazard due to supply voltage and DC-voltage from the solar modules. Only qualified electrical professionals are authorized to open the connection area of the FRONIUS IG and only provided that it is not under voltage.

Warning! An electric shock can be fatal. Inadequately sized electrical components can cause serious injuries to persons and damage to (or loss of) property.

Electrical installations must be in accordance with the National

Electrical Code, ANSI/NFPA 70.

Use minimum AWG 12 (AC) and AWG 12 (DC), min. 194 °F (90

°C), copper wire for the connection of the FRONIUS IG 2000,

3000 and 2500-LV

Use minimum AWG 10 (AC) and AWG 10 (DC), min. 194 °F (90

°C), copper wire for the connection of the FRONIUS IG 4000,

5100 and 4500-LV

Use minimum AWG 10 for all grounding cables.

Connection to the Solar Modules and to the Utility

Grid

Solar modules When selecting your solar modules to use with the FRONIUS IG unit, keep in mind this critical point: The no-load voltage increases when temperature decreases (assuming constant irradiance). Therefore, at 14 °C

(-10 °C) the open-circuit voltage must not exceed 500 V.

- Whenever the open-circuit voltage of the solar modules exceeds 500 V, the FRONIUS IG unit may be damaged, and all warranty rights will become null and void.

- More exact data for sizing the solar array for the particular location can be obtained using calculation tools such as the FRONIUS IG System

Configuration Tool (available on www.fronius-usa.com).

- See NEC table 690.7 for the appropriate code-related voltage adjustment factor for crystalline silicon modules, or use the manufacturer’s specified voltage coefficient.

45

Grid connection

Your FRONIUS IG unit needs to be connected to two phases (L1, L2) of the grid and to equipment grounding

Warning! In order to ensure the best possible operation of the grid monitoring system, it is important to make sure that there is minimal resistance in the lines to the connection point. The AC conductor resistance between the FRONIUS IG unit and the building’s distribution panel should not exceed 0.5 Ohm.

Schemes with more than one inverter

For larger photovoltaic schemes it is possible to connect several FRONI-

US IG units in parallel without any problems.

Note! The FRONIUS IG 2500-LV is designed to be connected to three phase systems. In order to ensure a symmetric feed-in of energy, a multiple of three FRONIUS IG 2500-LV and 4500-LV should typically be installed in a PV system. The connection to the grid shall be done in the following way:

- Connect FRONIUS IG 1, 4, 7, ... to L1 and L2

- Connect FRONIUS IG 2, 5, 8, ... to L2 and L3

- Connect FRONIUS IG 3, 6, 9, ... to L1 and L3

The connection of the FRONIUS IG to the solar modules and the grid is described within the following chapter and shown in the next figure:

Note! Connecting the DC wiring with the wrong polarity may cause damage to the inverter. Connect the DC cables as described in the following instructions.

Important! To access the DC terminals, the white plastic divider needs to be bent upward or rotated out of the way.

- Insert the DC cables through the DC conduit and connect them to the terminal block.

- Connect the positive (+) cables to the "DC+" terminals, and the negative

(-) cables to the "DC-" terminals.

Important! It is possible to connect up to 4 strings in parallel within the

FRONIUS IG 2000, 3000, 2500-LV. It is possible to connect up to 3 strings in parallel within the FRONIUS IG 4000, 5100, 4500-LV.

Note! Do not connect the ground to the DC negative at any point!

This is already done within the FRONIUS IG. If the DC negative is connected to ground at the DC terminal block or prior, this will circumvent the GFDI protection system, preventing your FRONIUS

IG from properly detecting a fault current. Additionally, turning the

DC disconnect to the off/open-circuit condition will not disconnect the array from ground, as it only disconnects the DC positive.

- Connect the module frame ground wire to the second terminal (5) labeled .

Note! Use minimum AWG 10 for all grounding cables.

- Torque wires with a torque of 20 in-lb.

- For your convenience, an additional grounding electrode terminal (6) is provided in case local regulations require additional grounding measures.

- Insert the AC cables through the AC conduit and connect them to the

AC disconnects labeled "L1" and "L2", as well as to the ground terminal

(1), labeled .

Note! Use minimum AWG 10 for all grounding cables.

Start up Operation

Configuring your Inverter

Factory preset configuration

Your FRONIUS IG unit has been pre-configured in the factory and is ready for operation.

After mounting the FRONIUS IG unit to the wall and connecting it to the solar modules (DC) and to the grid (AC), all you have to do is close the

AC and DC circuit disconnects.

LED

- as soon as the photovoltaic modules produce sufficient power, the status LED lights up orange and the screen displays the startup procedure

- the orange LED indicates that the feed-in mode of the FRONIUS IG will begin shortly

- after the FRONIUS IG unit has started feeding the energy into the grid, the LED light turns green

- the LED light continues green as long as power is fed into the grid. This confirms that the FRONIUS IG is operating properly and feeding energy into the grid.

In case the initial operation of your FRONIUS IG unit does not proceed as shown above and the FRONIUS IG unit does not start feeding power into the grid, consult the chapter "Error Diagnosis and Repair".

Your personal configuration

To change your inverter settings, please consult the chapter entitled "Operating Scheme", in the "Setup Menu" section of your operating instructions.

50

Ground fault indication

General The FRONIUS IG is equipped with a ground-fault detection and interruption (GFDI) circuit as required by UL 1741 and the National Elelctrical code.

If a ground fault occurs in the DC cabling the inverter disconnects from the grid. The fault is indicated by the red ground-fault LED and the service code "434" is shown on the display. In this situation the FRONIUS IG is blocked from reconnection to the grid until the following actions are taken:

- Turn the AC and DC disconnect to position OFF (open-circuit)

- Remove the ground fault in your photovoltaic system

- Test and replace the GFDI fuse if necessary

Note! When a defective fuse is changed, only replace it with a

"Littlefuse KLKD 1 AMP 600V" fuse.

Turn the AC and DC disconnect to position ON (closed circuit)

Note! In certain cases a ground fault can be detected and displayed before the GFDI fuse blows.

LocalNet

System upgrading / plug-in card system

Your FRONIUS IG can be upgraded through the addition of several Dat-

Com components for data monitoring:

- Datalogger (for recording and managing the data of your photovoltaic system on your personal computer, including modem tie in)

- Sensors (temperature sensors / irradiation sensors / ...)

FRONIUS has developed the LocalNet to provide unrestricted individual use of the system’s upgrades.

For complete installation instructions on the DatCom system, please see the DatCom Manual provided with your FRONIUS Datalogger. This information is also available on the web at www.fronius-usa.com.

Datalogger The Datalogger is the core of the LocalNet. It coordinates data transmission and ensures quick and safe distribution and storage of large volumes of data.

51

COM Card In order to connect the FRONIUS IG unit to the LocalNet, a COM Card is required

- COM Card ......................... for exchanging data between your FRONI-

US IG unit and the LocalNet.

The COM Card has the following connection terminals:

- 2 x RJ45 sockets labelled "IN" and "OUT" for connection of CAT 5 cables

- Power supply socket for the connection of 12 V low voltage power pack

(only necessary in certain cases as described in the FRONIUS IG Dat-

Com manual).

If the COM Card is to be installed in the field, proceed as follows:

Insert plug-in cards

Warning! Hazard due to supply voltage and DC-voltage from the solar modules. Only qualified electrical professionals are authorized to open the connection area and only when the inverter is not under voltage.

- Set the AC and DC disconnect to the OFF position

- open connection area - see section titled "Connection"

Note! The COM Card should be inserted in the slot named "ENS".

Note! In dealing with plug-in cards observe the general ESD regulations

- Insert card (2) into one of the slots of the control board.

- Tighten card (2) with fastening screw (1). A small metal plate is provided as a tool with the COM Card.

- Insert a 3/4 in. conduit fitting in the knockout (3) labeled "DatCom" and fasten it.

Note! Only use water tight conduits for the AC, DC and the optional DatCom knockouts.

- Insert DatCom cables (see manual FRONIUS IG DatCom through the

DatCom conduit and connect them to the sockets "IN" and "OUT"

- Close the connection area

- Set the AC and DC disconnects to the ON position.

52

Insert plug-in cards

Configuration LocalNet automatically identifies different system upgrades (Datalogger

Box, Sensor Box, ...).

However it is not able to differentiate between several identical system upgrades.

In order to define each FRONIUS IG unit in the LocalNet, the respective unit must have its own individual identification number.

For the respective procedure to assign these identification numbers, please consult the chapter "Setup Menu" in your operating instructions.

53

Example Recording and filing of inverter and sensor data by means of Datalogger and Sensor Box.

External communication (LocalNet) takes place via the COM Cards. Each

COM Card has two RS-485 interfaces: one for input one for output. Connections are made using RJ45 plugs.

The first FRONIUS IG unit with a COM Card can be located at a distance of up to 3300 ft. (1000 m) from the last FRONIUS IG unit with COM Card.

Note! Each FRONIUS IG that is to supply data must be equipped with a COM Card.

The Datalogger has one USB interface for connection to a personal computer and one RS-232 interface for connection to a modem.

Note! The order of sequence for placing the sensor boxes, datalogger box, and inverters does not matter.

However:

- Each FRONIUS IG can have only one COM Card

- Each network can contain only one Datalogger.

More information on the various system upgrade possibilities can be found in the respective service manuals or on the internet at www.fronius-usa.com.

Status diagnosis and repair

Service-Codes Displayed

Service display

Your FRONIUS IG unit is equipped with a self diagnostic system that automatically identifies a large number of possible operation issues by itself and displays them on the screen. Therefore it is possible to quickly isolate technical issues, and to distinguish between Service Codes related to the installation versus Service Codes which are internal to the inverter.

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

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

Normal operation service codes

As long as the open-circuit voltage of the solar modules is not sufficient, the screen displays the information "DC

LOW

."

As soon as the open-circuit voltage exceeds 150 V, the FRONIUS IG unit starts synchronizing with the grid (display shows "SYNC

AC

").

If the total power output of the solar modules is insufficient, the display shows the message "POWER

LOW

."

After a short time the FRONIUS IG resumes grid synchronization (message: "SYNC

AC

").

55

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

Should the no-load voltage of the modules (at the terminals within the

FRONIUS IG) not reach 160 V, it is possible that there is a problem on the

DC side of the photovoltaic system (e.g. wrong module configuration).

If the no-load voltage of the solar modules (at the terminals of the FRONI-

US IG unit) amounts to more than 160 V, there may be an issue with the

FRONIUS IG unit. In this case, consult a Fronius trained service technician.

FRONIUS IG with several power stage sets

A special status diagnostic is run if an error occurs in a FRONIUS IG with several power stage sets. The examples shown below illustrate the trouble-shooting process.

Important! It is also possible to call up state messages even if there is no actual error in existence. This form of status polling may be found in the set-up menu.
