6
For the location of the safety and danger notices on the device, refer to the "General" sec-
tion in the Operating Instructions for the device.
Before switching on the device, remove any faults that could compromise safety.
This is for your personal safety!
Environmental
conditions
Operation or storage of the device outside the stipulated area will be deemed as not in ac-
cordance with the intended purpose. The manufacturer shall not be held liable for any dam-
age arising from such usage.
Qualified service
engineers
The servicing information contained in these Operating Instructions is intended only for the
use of qualified service engineers. An electric shock can be fatal. Do not perform any ac-
tions other than those described in the documentation. This applies even if you are quali-
fied to do so.
All cables and leads must be secured, undamaged, insulated and adequately dimen-
sioned. Loose connections, scorched, damaged or inadequately dimensioned cables and
leads must be immediately repaired by authorised personnel.
Maintenance and repair work must only be carried out by authorised personnel.
It is impossible to guarantee that bought-in parts are designed and manufactured to meet
the demands made of them, or that they satisfy safety requirements. Use only original
spare parts (also applies to standard parts).
Do not carry out any modifications, alterations, etc. to the device without the manufactur-
er's consent.
Components that are not in perfect condition must be replaced immediately.
Noise emission
values
The maximum sound power level of the inverter is specified in the Technical Data.
The device is cooled as quietly as possible with the aid of an electronic temperature control
system; this depends on the amount of converted power, the ambient temperature, the lev-
el 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.
EMC measures In certain cases, even though a device complies with the standard limit values for emis-
sions, it may affect the application area for which it was designed (e.g. when there is sen-
sitive 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.
Data protection The user is responsible for the safekeeping of any changes made to the factory settings.
The manufacturer accepts no liability for any deleted personal settings.
Copyright Copyright of these operating instructions remains with the manufacturer.

General
Device concept Device design:
(1) Housing lid
(2) Inverter
(3) Wall bracket
(4) Connection area incl. DC main
switch
(5) Data communication area
(6) Data communication cover
The inverter converts the direct current
created in 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 sys-
tems; it is impossible to generate energy independently of the public grid.
Thanks to its design and the way it works, the inverter is extremely safe both to install and
to operate.
The inverter automatically monitors the public grid. In the event of abnormal grid condi-
tions, 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.).
Grid monitoring involves monitoring voltage, frequency and the stand-alone situation.
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 ob-
tained 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).
The Fronius Eco does not have an internal boost converter. This results in certain restric-
tions in the choice of solar module and string. The minimum DC input voltage (UDC min)
depends on the grid voltage. On the other hand, a highly optimised device is then available
for the appropriate application.

Proper use/in-
tended purpose
The inverter is intended exclusively to convert direct current from solar modules into alter-
nating 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 Froni-
us.
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

Text of the warning notices:
WARNING!
An electric shock can be fatal. Make sure that both the input side and output side of the
device are de-energised before opening the device. Wait for the capacitors to discharge (5
minutes).
Controlling the in-
verter via De-
mand Response
Modes (DRM)
Notes regarding
dummy devices
A dummy device is not suitable for connecting operationally to a photovoltaic system, and
must only ever be used for demonstration purposes.
IMPORTANT! Never connect DC cables to the DC connection sockets on a dummy de-
vice.
The connection of de-energised cables or sections of cable for demonstration purposes is
permissible.
A dummy device can be recognised by its device rating plate:
Example: Device rating plate of a dummy device
Dangerous electrical voltage
Wait for the capacitors to discharge.
To comply with the European Directive 2012/19/EU on Waste Electrical and Elec-
tronic Equipment and its implementation as national law, electrical equipment that
has reached the end of its life must be collected separately and returned to an
approved recycling facility. Any device that you no longer require must be re-
turned to your distributor, or you must locate the approved collection and recy-
cling facilities in your area. Ignoring this European Directive may have potentially
adverse effects on the environment and your health!
IMPORTANT! To control the inverter via DRM, a Fronius DRM interface (item number
4,240,005) is required in the inverter.
Installation is described in the installation instructions for the Fronius DRM interface. The
installation instructions for the Fronius DRM interface are available at the following link on
the Fronius homepage:

String fuses WARNING!
An electric shock can be fatal.
Danger from voltage at the fuse holders. The fuse holders are live when voltage is present
on the DC connection of the inverter, even when the DC switch is switched off. Make sure
that the DC side is de-energised before carrying out any work on the inverter fuse holder.
String fuses are used in the Fronius Eco to provide additional protection for the solar mod-
ules.
The maximum short circuit current Isc, the maximum module return current IR or the maxi-
mum string fuse rating specified in the module data sheet of the respective solar module
is crucial in affording the solar modules the correct fuse protection.
The maximum short circuit current ISC per terminal is 15 A.
Where necessary, a tripping current higher than 15 A may be selected for the string fuses.
A tripping current of 20 A must not be exceeded.
If the inverter is operated with an external string combiner box, a DC Connector Kit must
be used (item number: 4,251,015). In this case the solar modules are protected externally
in the string combiner box, and the metal bolts need to be used in the inverter.
The national regulations regarding fuse protection must be observed. The electrical engi-
neer carrying out the installation is responsible for the correct choice of string fuses.
NOTE!
To avoid the risk of a fire, only replace faulty fuses with new ones of the same rating.
As an option, the inverter can be supplied with the following fuses:
- 6 x 15 A string fuses on the DC+ input and 6 x metal pins on the DC- input
- 12 x metal pins

Criteria for select-
ing the right
string fuses
The following criteria must be met for each solar module string when selecting suitable fus-
es:
- IN > 1.8 x ISC
- IN < 2.4 x ISC
- VN >/= maximum open circuit voltage of pv generator
- Fuse dimensions: diameter 10 x 38 mm
INNominal current of fuse
ISC Short circuit current for standard test conditions (STC) according to the solar mod-
ule data sheet
VNRated voltage of fuse
NOTE!
The nominal current rating of the fuse must not exceed the maximum fuse protec-
tion specified in the data sheet supplied by the solar module manufacturer.
If a maximum fuse protection is not specified, then this information must be requested from
the solar module manufacturer.

Data communication and Fronius Solar Net
Fronius Solar Net
and data interface
Data communica-
tion area
Depending on the model, the inverter may be equipped with the Fronius Datamanager
plug-in card (8).
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 communi-
cation between one or several inverters that are connected on the Fronius Solar Net us-
ing 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 as-
signed 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

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 con-
necting 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:
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 in-
puts and outputs. RJ45 plug connectors are used to make the connection.
IMPORTANT! Since the Fronius Datamanager functions as a datalogger, the Fronius So-
lar Net ring must not include any other datalogger.
There must only be one Fronius Datamanager in each Fronius Solar Net ring.
Fronius Symo 3 - 10 kW: Any other Fronius Datamanagers must be removed and the un-
occupied option card slot sealed off using the blanking cover (42,0405,2020 - available
from Fronius as an optional extra); alternatively, use an inverter without Fronius Datama-
nager (light version).
Fronius Symo 10 - 20 kW, Fronius Eco: Any other Fronius Datamanagers must be re-
moved and the unoccupied option card slot sealed off by replacing the cover (item no.

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 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 imped-
ance)
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 protection device
Depending on the setting in the Basic menu (Signal Input submenu), the DC SPD option
(surge protection device) either outputs a warning or an error on the display. Further infor-
mation 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 in-
verter. This S0 meter can be positioned directly at the feed-in point or in the consumption
branch. As one of the settings on the Fronius Datamanager website, a dynamic power re-
duction can be set under the "EVU Editor" menu item (see Fronius Datamanager 2.0 Op-
erating Instructions on our website www.fronius.com)
IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to up-
date the inverter firmware.
Requirements for the S0 meter:
- Must comply with the IEC62053-31 Class B standard
- Max. voltage 15 V DC
- Max. current when ON 15 mA
- Min. current when ON 2 mA
- Max. current when OFF 0.15 mA

ager during the
night or when the
available DC volt-
age 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).

or
input for an external supply voltage
>12.8 - 24 V DC (+ 20%)
Digital inputs: 0 - 3, 4 - 9
Voltage level: low = min. 0V - max. 1.8V; high = min. 3V - max. 24V DC (+ 20%)
Input currents: dependent on input voltage; input resistance = 46 kOhm
Digital outputs: 0 - 3
Switching capacity when power is supplied by the Fronius Datamanager 2.0 plug-in
card: 3.2 W in total for all 4 digital outputs
Switching capacity when power is supplied by an external power supply delivering
min. 12.8 - max. 24 V DC (+ 20%), connected to Uint / Uext and GND: 1 A, 12.8 -
24 V DC (depending on external power supply) for each digital output
The connection to the I/Os is established via the mating connector supplied.
(8) Antenna socket
This is where the WLAN antenna is connected
(9) Modbus termination switch (for Modbus RTU)
Internal bus terminator with 120 ohm resistor (yes/no)
Switch in "on" position: 120 ohm terminating resistor active
Switch in "off" position: no terminating resistor active
IMPORTANT! On an RS485 bus, the terminating resistor on the first and last device
must be active.
(10) Fronius Solar Net Master / Slave switch
To switch from master to slave mode within a Fronius Solar Net ring
IMPORTANT! In slave mode, all the LEDs on the Fronius Datamanager 2.0 plug-in
card are off.

Using for the first
time
Setting up the Fronius Datamanager 2.0 for the first time is made considerably easier with
the Fronius Solar.web app. The Fronius Solar.web app is available in the respective app
stores.
When starting 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. lap-
top, 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.
Connect inverter with Fronius Datamanager 2.0 or Fronius Datamanager Box 2.0 to
the Fronius Solar Net
When networking several inverters together in Fronius Solar Net:
Set the Fronius Solar Net master / slave switch on the Fronius Datamanager 2.0 plug-
in card correctly
-One inverter with Fronius Datamanager 2.0 = master
-All other inverters with Fronius Datamanager 2.0 = slave (the LEDs on the Fronius
Datamanager 2.0 plug-in cards are not illuminated)
Switch the device to Service mode
-Activate the WiFi Access Point via the Setup menu on the inverter
The inverter establishes the WiFi access point. The WiFi access point remains open for 1
hour. The IP switch on the Fronius Datamanager 2.0 can remain in switch position A due
to the activation of the WiFi Access Point.
