General
Device concept Device design:
(1) Housing cover
(2) Inverter
(3) Wall bracket
(4) Connection area incl. DC main
switch
(5) Data communication area
(6) Data communication cover
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.
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
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).
The Fronius Eco does not have an internal boost converter. This results in certain
restrictions in the choice of solar module and string. The minimum DC input
voltage (U
ised device is then available for the appropriate application.

Electronic 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 returned to your distributor or disposed of at
an approved collection and recycling facility in your area. Ignoring this
European Directive may have potentially adverse effects on the environment and your health!
Text of the warning notices:
WARNING!
An electric shock can be fatal. Before opening the device, it must be disconnected at the input and output. Wait for the capacitors to discharge (5 minutes).
Controlling the
inverter via Demand Response
Modes (DRM)
Symbols on the rating plate:
CE mark – confirms compliance with applicable EU directives and
regulations.
UKCA mark – confirms compliance with applicable UK directives and
regulations.
WEEE mark – waste electrical and electronic equipment must be
collected separately and recycled in an environmentally sound manner
in accordance with the European Directive and national law.

import regulations and compliance with Moroccan standards.
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 on the Fronius homepage at the following link:

http://www.fronius.com/QR-link/4204102292
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 modules.
The short circuit current Isc and the maximum series string fuse data (e.g. max-
imum series fuse rating) specified in the module data sheet of the respective PV
module are crucial in affording the PV modules the correct fuse protection.
The maximum string fuse rating per terminal is 20 A.
The maximum MPP current (nominal current, operating current) I
is 15 A per
max
string.
If three strings are connected, strings 1.1, 2.1, 2.3 must be used.
If four strings are connected, strings 1.1, 1.2, 2.1, 2.2 must be used.
If the inverter is being 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.
EN
The national regulations regarding fuse protection must be observed. The electrical engineer 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
-
11
Criteria for selecting the right
string fuses
In order to prevent premature tripping of the fuse during normal operation, it is
recommended that the following criteria be met per individual solar module
string when fusing-protecting the solar module strings:
IN > 1.5 x I
-
VN >/= max. open-circuit voltage of the PV generator
-
Fuse dimensions: diameter 10 x 38 mm
-
SC

NOTE!
The nominal current rating of the fuse must not exceed the maximum fuse protection specified in the data sheet supplied by the PV module manufacturer.
If a maximum fuse protection is not specified, then this information must be requested from the PV module manufacturer.

Data communication and Fronius Solar Net
EN
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:

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.

Datamanager and a Fronius Sensor Box:
EN
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 datalogger, the
Fronius Solar Net ring must not include any other datalogger.
There must only be one Fronius Datamanager in each Fronius Solar Net ring.

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
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.
The S0 meter must comply with the IEC62053-31 Class B standard
Recommended max. pulse rate of the S0 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

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 16
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 45.
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.
EN
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).

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.

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.
