CAUTION!

If not avoided, minor injury and/or damage to property may result.

NOTE!

The inverter transforms the direct current generated by the solar modules into alternating current. This alternating current is fed into the public grid synchronously with the grid voltage.

The inverter has been developed exclusively for use in grid-connected photovoltaic systems; it is impossible to generate energy independently of the public grid.

The inverter automatically monitors the public grid. In the event of abnormal grid conditions, the inverter ceases operating immediately and stops feeding power into the grid (e.g. if the grid is switched off, if there is an interruption, etc.). The grid is monitored by monitoring the voltage, frequency and islanding conditions.

The inverter operates fully automatically. As soon after sunrise as there is sufficient energy available from the solar modules, the inverter starts monitoring the grid. When insolation has reached a sufficient level, the inverter starts feeding energy into the grid. The inverter operates in such a way that the maximum possible amount of power is obtained from the solar modules. As soon as the power available has fallen below the level at which energy can be

fed into the grid, the inverter disconnects the power electronics completely from the grid and stops running. It retains all its settings and stored data.

If the inverter becomes too hot, it automatically reduces the current output power in order to protect itself. Reasons for the inverter becoming too hot include the ambient temperature being too high or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat dissipation).

Proper use/ intended purpose

The inverter is intended exclusively to convert direct current from solar modules into alternating current and to feed this into the public grid. Utilisation not in accordance with the intended purpose comprises:

Any use above and beyond this purpose

Making any modifications to the inverter that have not been expressly ap-

proved by Fronius the installation of components that are not distributed or expressly ap-

proved by Fronius.

Fronius shall not be liable for any damage resulting from such action. No warranty claims will be entertained.

Proper use also includes:

Carefully reading and obeying all the instructions and all the safety and

danger notices in the Operating Instructions and Installation Instructions Performing all stipulated maintenance work

Installation as specified in the Installation Instructions

When designing the photovoltaic system, ensure that all components are operated within their permitted operating ranges at all times.

Observe all the measures recommended by the solar module manufacturer to ensure that the solar module retains its properties in the long term.

Obey the regulations of the power supply company regarding connection methods and energy fed into the grid.

Warning notices on the device

There are warning notices and safety symbols on and in the inverter. These warning notices and safety symbols must not be removed or painted over. They warn against incorrect operation, as this may result in serious injury and damage.

Data communication and Fronius Solar Net

Fronius Solar Net and data interface

Fronius Solar Net was developed to make system add-ons ﬂexible to use in a variety of different applications. Fronius Solar Net is a data network that enables multiple inverters to be linked up using system add-ons.

It is a bus system that uses a ring topology. One suitable cable is sufficient for communication between one or several inverters that are connected on the Fronius Solar Net using a system add-on.

Similarly, every inverter on the Fronius Solar Net must be assigned a unique number. Refer to the section entitled "The SETUP menu item" for instructions on how to assign a unique number.

Fronius Solar Net automatically recognises a wide variety of system add-ons.

In order to distinguish between several identical system add-ons, each one must be assigned a unique number.

More detailed information on the individual system add-ons can be found in the relevant operating instructions or on the internet at http://www.fronius.com

More detailed information on cabling Fronius DATCOM components can be found at:

→ http://www.fronius.com/QR-link/4204101938

Data communication area

Depending on the model, the inverter may be equipped with the Fronius Datamanager plug-in card (8).

Ite m Description

Various wiring variants can be connected to the multifunction current interface. However, these cannot be operated simultaneously. For example, if an S0 meter is connected to the multifunction current interface, it is not possible to connect a signal contact for the surge protection device (or vice versa).

Pin 1 = measurement input: max. 20 mA, 100 Ohm measurement resistor (load impedance) Pin 2 = max. short circuit current 15 mA, max. open-circuit voltage 16 V DC or GND

Wiring diagram variant 1: Signal contact for surge protective device

Depending on the setting in the Basic menu (Signal Input submenu), the DC SPD option (surge protective device) either outputs a warning or an error on the display. Further information on the DC SPD option can be found in the Installation Instructions.

Wiring diagram variant 2: S0 meter

A meter for recording the self-consumption of each S0 can be connected directly to the inverter. This S0 meter can be positioned directly at the feed-in point or in the consumption branch.

IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to update the inverter firmware.

there are too many DATCOM components on the Fronius Solar Net and not enough electrical power is available)

In this case, power for the Fronius DATCOM components must be supplied by connecting an additional power supply (43,0001,1194) to one of the Fronius DATCOM components.

To detect the presence of an undervoltage, check some of the other Fronius DATCOM components for faults as required.

After cutting out because of overcurrent or undervoltage, the inverter attempts to restore the power supply in the Fronius Solar Net every 5 seconds while the fault is still present.

Once the fault is rectified, power to the Fronius Solar Net will be restored within 5 seconds.

Example Recording and archiving data from the inverter and sensor using a Fronius

Datamanager and a Fronius Sensor Box:

Installing option cards in the inverter

Data network with 3 inverters and a Fronius Sensor Box:

- Inverter 1 with Fronius Datamanager

- Inverters 2 and 3 without Fronius Datamanager!

The external communication (Fronius Solar Net) takes place on the inverter via the data communication area. The data communication area contains two RS 422 interfaces as inputs and outputs. RJ45 plug connectors are used to make the connection.

IMPORTANT! Since the Fronius Datamanager functions as a data logger, the Fronius Solar Net ring must not include any other data logger. Only one Fronius Datamanager per Fronius Solar Net ring! Any other Fronius Datamanagers must be removed and the unoccupied option card compartment sealed off using the blanking cover (42,0405,2020 - available from Fronius as an optional extra); alternatively, use an inverter without Fronius Datamanager (light version).

Information on installing option cards (e.g.: Datamanager) in the inverter and connecting the data communication cable can be found in the Installation Instructions.

= Terminating plug

Dynamic power reduction by means of inverter

Energy companies or grid operators may impose feed-in limits on an inverter. Dynamic power reduction takes account of self-consumption by the household before the power of an inverter is reduced:

A counter for determining self-consumption of the S0 can be connected directly to the inverter – see chapter Explanation of the multifunction current interface on page 12

A feed-in limit can be set in the Basic menu under Signal input – S0 meter – see chapter Menu items in the Basic menu on page 43.

Setting options for S0 meter:

Grid feed-in limit

Field for entering the maximum grid feed-in power in W. If this value is exceeded, the inverter regulates down to the set value within the time required by national standards and regulations.

Pulses per kWh

Field for entering the pulses per kWh of the S0 meter.

Zero feed-in is possible with this configuration.

When using the S0 meter and power reduction by means of an inverter, the S0 meter must be installed in the consumption branch.

S0 meter in the consumption branch

If dynamic power reduction is subsequently configured using the Fronius Datamanager 2.0 (Inverter user interface - UC Editor menu - Dynamic power reduction), dynamic power reduction must be deactivated using the inverter (Inverter display - Basic menu - Signal input - S0 meter).

System monitoring

General The inverter is fitted with the WLAN-enabled system monitoring Fronius

Datamanager 2.0 as standard. The following functions are included with the system monitoring:

Dedicated web page displaying current data and a wide range of settings
