Explanation of safety notices

WARNING!

Indicates a potentially hazardous situation.

▶ If not avoided, death or serious injury may result.

CAUTION!

Indicates a situation where damage could occur.

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

NOTE!

Indicates a risk of flawed results and possible damage to the equipment.

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 approved by Fronius
• the installation of components that are not distributed or expressly approved 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

Data communication and Fronius Solar Net

Z

Fronius Solar Net and data in- terface

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:

Explanation of the multifunction current interface

Various wiring variants can be connected to the multifunction current interface. However, these cannot be operated simultaneously. For example, if an SO 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: So meter

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

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

The S0 meter must comply with the IEC62053-31 Class B standard

Recommended max. pulse rate of the SO meter: PV output kWp [kW] Max. pulse rate per kWp

30 1000
20 2000
10 5000
≤ 5.5 10000 

With this meter, dynamic power reduction can be performed in two ways:

• Dynamic power reduction by means of inverter
  For more information see chapter Dynamic power reduction by means of inverter on page 15
• Dynamic power reduction by means of the Fronius Datamanager 2.0
  for more info see: manuals.fronius.com/html/4204260191/#0_m_0000017472

Description of the "Fronius Solar Net" LED

The "Fronius Solar Net" LED is on:

the power supply for data communication within the Fronius Solar Net / interface protocol is OK

The "Fronius Solar Net" LED flashes briefly every 5 seconds:

data communication error in the Fronius Solar Net

• Overcurrent (current flow > 3 A, e.g. resulting from a short circuit in the Fronius Solar Net ring)
• Undervoltage (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if 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:

PC WLAN * Fronius Datamanager 1 2 Sensor Box 3 IN OUT IN OUT IN OUT °C W/m² m/s

Data network with 3 inverters and a Fronius Sensor Box:

• Inverter 1 with Fronius Datamanager
• Inverters 2 and 3 without Fronius Datamanager!

● = Terminating plug

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).

Installing option cards in the inverter

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

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 SO 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 – SO meter – see chapter Menu items in the Basic menu on page 43.

Setting options for SO 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 SO meter.

Zero feed-in is possible with this configuration.

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

Datamanager during the night or when the available DC voltage is insufficient

The Night Mode parameter under "Display Settings" in the Setup menu is preset to OFF in the factory.

For this reason the Fronius Datamanager cannot be accessed during the night or when the available DC voltage is insufficient.

To nevertheless activate the Fronius Datamanager, switch the inverter off and on again at the mains and press any function button on the inverter display within 90 seconds.

See also the chapters on "Menu items in the Setup menu", "Display settings" (Night Mode).

Starting for the first time

Starting the Fronius Datamanager 2.0 for the first time is made considerably easier with the Fronius Solar.start app. The Fronius Solar.start app is available in the respective app stores.

When starting the Fronius Datamanager 2.0 for the first time,

• the Fronius Datamanager 2.0 plug-in card must be installed in the inverter, or
• there must be a Fronius Datamanager Box 2.0 in the Fronius Solar Net ring.

IMPORTANT! In order to establish a connection to Fronius Datamanager 2.0, "Obtain IP address automatically (DCHP)" must be activated on the end device in question (e.g. laptop, tablet, etc.).

NOTE!

If the photovoltaic system has only one inverter, steps 1 and 2 below can be skipped.

In this case, starting for the first time will commence with step 3.

1 Connect inverter with Fronius Datamanager 2.0 or Fronius Datamanager Box 2.0 to the Fronius Solar Net

2 When networking several inverters in Fronius SolarNet:

Set the Fronius Solar Net client/server switch on the Fronius Datamanager 2.0 plug-in card correctly

10 min.

5 min. The logging interval is 5 minutes; every 5 minutes new logging data will be saved to the USB flash drive.

No log No data is saved

IMPORTANT! In order for the USB logging function to work correctly the time must be set correctly. Setting the time is discussed in the section "Menu items in the Setup menu" - "Clock".

Relay (floating contact switch)

Status codes (state codes), the status of the inverter (e.g. feeding energy into the grid) or Energy Manager functions can be displayed using the floating switch contact (relay).

Setting range Relay mode / Relay test / Switch-on point* / Switch-off point*

* these are only shown if the "E-Manager" function has been activated under "Relay mode".

Relay mode

The following functions can be shown using relay mode:

• Alarm function (Permanent / ALL / GAF)
• Active output (ON / OFF)
• Energy Manager (E-Manager)

Setting range ALL / Permanent / GAF / OFF / ON / E-Manager

Factory setting ALL

Alarm function:

ALL / Per- manent:

Switching the floating switch contact for permanent and temporary service codes (e.g. brief interruption to energy being fed into the grid, a service code occurs a certain number of times a day - can be adjusted in the "BASIC" menu)

GAF As soon as GAF mode is selected, the relay is switched on.

The relay opens as soon as the power stage set registers an error and goes from normally feeding energy into the grid to being in an error state. This means that the relay can be used for fail-safe functions.

Application example

It may be necessary to perform phase compensation when using a single-phase inverter at a multiphase site. If an error occurs on one or several inverters and the connection to the grid is broken, the other inverters must also be disconnected to maintain the phase balance. The "GAF" relay function can be used in conjunction with the Datamanager or an external protection device to recognise or signal that an inverter is not feeding in or is disconnected from the grid and to then disconnect the remaining inverters from the grid using a telecontrol command.

Active output:

ON: The floating NO contact is on all the time the inverter is in operation (as long as the display is not dark or is displaying something).

OFF: The floating NO contact is off.

Energy Manager:

E-Manager: Further details on the "Energy Manager" function may be found in the "Energy Manager" section.

Relay test

Function test to determine whether the floating switch contact switches

Switch-on point (only if "Energy Manager" function is activated)

for setting the effective power limit beyond which the floating switch contact is switched on

Factory setting 1000 W

Setting range Set switch-off point up to the maximum nominal output of the inverter (W or kW)

Switch-off point (only if "Energy Manager" function is activated)

for setting the effective power limit beyond which the floating switch contact is switched off

Factory setting 500

Setting range 0 to the set switch-on point of the inverter (W or kW)

Energy Manager (under Relay menu item)

The "Energy Manager" (E-Manager) function can be used to activate the floating switch contact in such a way that it functions as an actuator.

Thus, a consumer that is connected to the floating switch contact can be controlled by specifying a switch-on or switch-off point that depends on the feed-in power (effective power).

The floating switch contact is automatically switched off:

- If the inverter is not feeding any power into the grid

- If the inverter is manually switched to Standby mode

- If the effective power is set to < 10% of the nominal output of the inverter.

To activate the Energy Manager function, select the "E-Manager" item and press the "Enter" key.

When the "Energy Manager" function is running, the "Energy Manager" symbol will appear in the top left corner of the display:

When the floating NO contact is off (open contact)
When the floating NC contact is on (closed contact)

To deactivate the Energy Manager function, select a different function (ALL / Permanent / OFF / ON) and press the "Enter" key.

NOTE!

Notes on setting up the switch-on and switch-off points If the difference between the switch-on and switch-off points is too small, or if there are fluctuations in effective power, the result may be multiple switching cycles.

To avoid switching on and off frequently, the difference between the switch-on and switch-off points should be at least 100 - 200 W.

When choosing the switch-off point, the power consumption of the connected consumer should be taken into account.

When choosing the switch-on point, the weather conditions and anticipated insolation should be taken into account.

Application example

Switch-on point = 2000 W, switch-off point = 1800 W

If the inverter is outputting 2000 W or above, then the floating switch contact on the inverter is switched on.

If the inverter output falls to below 1800 W, the floating switch contact is switched off.

This allows useful applications, such as operating a heat pump or an air-conditioning system using as much self-generated power as possible, to be implemented quickly

USB Stick as a Data Logger and for Updating Inverter Software

EN

USB flash drive as a datalogger

If a USB flash drive is connected to the USB A socket it can function as a datalogger for an inverter.

At any time, the logging data stored on the USB flash drive can be

• imported into the Fronius Solar.access software using the FLD file that was logged at the same time,
• viewed directly in third-party programs (e.g. Microsoft® Excel) using the CSV file logged at the same time.

Older versions (before Excel 2007) are limited to a maximum of 65,536 rows.

Further information on "Data on a USB flash drive", "Data volume and storage capacity" as well as "Buffer memory" can be found at:

→ http://www.fronius.com/QR-link/4204260204DE

Suitable USB flash drives

Due to the variety of USB flash drives available on the market, it cannot be guaranteed that every USB flash drive will be detected by the inverter.

Fronius recommends that only certified, industry-grade USB flash drives are used (look out for the USB-IF logo).

The inverter supports USB flash drives with the following file systems:

• FAT12
• FAT16
• FAT32

Fronius recommends that the USB flash drive employed should only be used for recording logging data or updating the inverter software. The USB flash drives should not contain any other data.

USB symbol on the inverter display, e.g. in display mode 'NOW':

↓ | NOW | ↓ AC Output Powe 2847W

If the inverter detects a USB flash drive, the USB symbol will appear in the top right corner of the display.

When inserting a USB flash drive, check whether the USB symbol is displayed (it may also flash).

Note! Please note for outdoor applications that conventional USB flash drives are often only guaranteed to work within a restricted temperature range. For outdoor applications ensure that the USB flash drive also functions, for example, at low temperatures.

USB stick for up- dating the in- verter software

With the help of the USB stick, end customers can also update the inverter software via the USB item on the SETUP menu: the update file is first saved to the USB stick, from where it is then transferred to the inverter. The update file must be saved in the root directory on the USB stick.

Removing the USB flash drive

Safety instruction concerning the removal of a USB flash drive:

Do not disconnect USB-Stick while LED is flashing!

IMPORTANT! To avoid any loss of data, a USB flash drive may only be removed if the following conditions are met:

Status diagnostics and troubleshooting

Status code dis- play

The inverter performs a system self-diagnosis that automatically detects many faults that may occur and shows them on the display. This means you are promptly made aware of malfunctions in the inverter or the photovoltaic system, or of any installation or operating faults.

If the system self-diagnosis has detected a specific fault, the associated status code will be shown on the display.

IMPORTANT! Status codes may sometimes appear briefly as a result of the inverter's control response. If the inverter then continues working with no sign of any problem, this means that there was no fault.

Total failure of the display

If the display fails to come on some time after sunrise:

- Check the AC voltage ON the inverter connections: the AC voltage must be 230 V (+ 10 % / - 5 %)*.

* The mains voltage tolerance depends on the country setup

Explanation of footnotes

1) The values stated are defaults; the inverter is configured specifically to suit the requirements of the relevant country.
2) Depending on the country setup or device-specific settings (ind. = inductive; cap. = capacitive).
3) Maximum current from a defective PV module to all other PV modules. From the inverter itself to the PV side of the inverter, it is O A.
4) Guaranteed by the electrical configuration of the inverter
5) Current peak when switching on the inverter
6) Specified values are standard values; depending on the requirement and PV power, these values must be adjusted accordingly.
7) Specified value is a max. value; exceeding the max. value may negatively affect the function.
8) I_SC PV = I_SC max ≥ I_SC (STC) × 1.25 according to e.g.: IEC 60364-7-712, NEC 2020, AS/NZS 5033:2021
