Data Regarding
Noise Emission
Values
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.
Safety symbols Devices marked with the CSA test mark satisfy the requirements of the relevant standards
for Canada and the USA.
Disposal Dispose of in accordance with the applicable national and local regulations.
Backup The user is responsible for backing up any changes made to the factory settings. The man-
ufacturer accepts no liability for any deleted personal settings.
Copyright Copyright of these operating instructions remains with the manufacturer.
Text and illustrations are technically correct at the time of going to print. The right to make
modifications is reserved. The contents of the operating instructions shall not provide the
basis for any claims whatsoever on the part of the purchaser. If you have any suggestions
for improvement, or can point out any mistakes that you have found in the operating in-
structions, we will be most grateful for your comments.
The cooling of the device takes place via an electronic temperature control
system at the lowest possible noise level and depends on the power used, am-
bient temperature and the soiling level 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 installa-
tion situation, the power quality, the surrounding walls and the properties of
the room in general.

General
Device concept Unit design:
(1) Housing cover
(2) Inverter
(3) Mounting bracket
(4) Connection area including DC main
switch
(5) Data Communication Area
(6) Data communication cover
The inverter transforms the direct current
generated by the solar modules into alter-
nating current. This alternating current is
fed into the public grid and synchronized
with the mains voltage in use.
The inverter has been designed exclusively for use in grid-connected photovoltaic sys-
tems. It cannot generate electric power independently of the grid.
The inverter automatically monitors the public grid. Whenever conditions in the electric grid
are inconsistent with standard conditions (e.g., grid switch-off, interruption), your inverter
will immediately stop operating and interrupt the supply of power into the grid.
The grid is monitored by monitoring the voltage, monitoring the frequency and monitoring
islanding conditions.
The inverter is fully automatic. The inverter starts monitoring the grid as soon as the solar
modules are generating enough energy after sunrise. The inverter resumes the grid power
feed operation when there is sufficient direct sunlight.
The control system of the inverter ensures that the maximum possible power output is
drawn from the solar modules at all times.
As soon as there is no longer sufficient energy available for the grid power feed operation,
the inverter shuts down the power electronics connection to the grid completely and stops
operating. All settings and recorded data are saved.
When its temperature gets too high, the inverter automatically reduces the current output
power in order to protect itself.
Reasons for the temperature being too high include a high ambient temperature or insuffi-
cient heat dissipation (e.g., inadequate heat dissipation when installed in switch cabinets).
Intended Use The inverter is designed exclusively to convert direct current from solar modules into alter-
nating current and feed this power into the public grid.
The following are deemed to be not in conformity with its intended purpose:
- Utilization for any other purpose, or in any other manner
- Alternations to the inverter are not expressly recommended by Fronius
- Installation of components that are not expressly recommended or sold by Fronius.
The manufacturer is not responsible for any damage resulting from improper use.
All warranty claims are considered void in such cases.

(4)(5)(6)

10
Proper use also means
- carefully reading and obeying the instructions and all the safety and danger notices in
the Operating and Installation Instructions
- compliance with the maintenance operations
- installation as specified in the Installation Instructions
When configuring the photovoltaic system, make sure that all components are operating
completely within their permitted operating range.
All measures recommended by the solar module manufacturer for maintaining solar mod-
ule properties must be followed.
Follow all grid operator regulations regarding grid power feed and connection methods.
Information on
‘Field-adjustable
trip points’ and
‘Advanced Grid
Features’
The inverter is equipped with ‘Field adjustable trip points’ and ‘Advanced Grid Features’.

Insulation Moni-
tor/Interruption,
Insulation Moni-
toring
The inverter is equipped with the following safety features as required by UL 1741 and the
National Electrical Code:
Insulation monitor (IMI/RCMU)
The IMI (isolation monitor interruptor) feature is performed by the RCMU (residual current
monitoring unit) feature in the inverter. This feature automatically monitors whether a leak-
age current exists in the grid power feed operation. The inverter is disconnected from the
grid if a defined leakage current is exceeded.

11
EN-US
NOTE!
Automatic reconnection no longer occurs after the device is disconnected from the
grid five times as a result of exceeding the defined leakage current value.
The State Code 607 shown on the display must be acknowledged to reconnect.
Insulation monitoring of ungrounded solar modules
In the case of grid connected photovoltaic systems with ungrounded solar modules, the in-
verter checks the insulation resistance between the positive and negative pole in relation
to the earth potential before energy is fed into the grid. The inverter issues a state code if
the insulation resistance is too low. The inverter is therefore not permitted to start feeding
energy into the grid.
Arc detection/in-
terruption
The inverter is equipped with integrated arc detection/interruption, which detects and ex-
tinguishes serial arcs.
For example, a serial arc can occur after the following errors or situations:
- Poorly-connected plug connections on the solar module
- Poor or defective cable connections on the solar module side, which enable a connec-
tion against the earth potential
- Defective solar modules due to problems in the junction box or production errors, such
as high resistance solder connections in individual solar cells
- Cables incorrectly connected to an inverter’s input terminals
If a serial arc is detected, the power is switched off and the grid power feed operation is
interrupted. A state code is shown on the display. The state code on the display must be
manually reset before the grid power feed operation can be resumed.
The power shutdown also extinguishes the serial arc.
NOTE!
This product is equipped with a communication interface in line with the "Commu-
nication Signal for Rapid Shutdown - SunSpec Interoperability Specification”.
Power optimizers and other MLPE features in the photovoltaic system can impair the cor-
rect functioning of the arc detection/interruption. When using these kinds of components,
the system installer is responsible for ensuring the correct functioning of the arc detection/
interruption. Contact your Fronius Technical Support for more information.
Power Line Com-
munication (PLC)
Transmitter
This inverter is equipped with a Power Line Communication (PLC) Transmitter on the DC
side.
The purpose is to provide Rapid Shutdown acc. to NEC Edition 2017 Art. 690.12. The PLC
is implemented according to the Specification "Communication Signal for Rapid Shutdown
- SunSpec Interoperability Specification". Details can be found at www.sunspec.org
To ensure compliance with all regulations applicable in your country and to provide best
reception at the receivers, please follow the recommendations below:
- Keep distance between DC+ and DC- Conductors as close as possible
- Avoid cable loops of excessive cables (coiling).
- Use metallic raceways where possible
- Do not run DC cables from different inverters in the same raceway or cable tray.

13
EN-US
Example: Dummy device rating plate
String fuses Only valid for the device types with the “Ecofuse” option:
The use of string fuses provides additional fuse protection for solar modules.
The maximum short circuit current ISC, the maximum module backfeed current IR, and the
specification of the maximum string fuse value in the module data sheet of the respective
solar module are decisive factors in the protection of the solar module.
The maximum short circuit current ISC per terminal is 15 A.
The string fuse release current can be set to greater than 15 A if required. However, a re-
lease current of 20 A must not be exceeded.
If the inverter is being operated with an external string collection box, the DC connector kit
25 (item numbers 42,0201,4479 for DC+ and 42,0201,4480 for DC-) must be used. In this
case the solar modules are externally protected in the string collection box and the metal
bolts should be used in the inverter.
National regulations regarding fuse protection must be observed. The electrician perform-
ing the installation is responsible for choosing the right string fuses.
NOTE!
To prevent a risk of fire, faulty fuses must only be replaced by new equivalent fuses.
The inverter is delivered with metal bolts as standard.

Data Communication and Fronius Solar Net
Fronius Solar Net
and data interface
Data Communica-
tion Area
Depending on the version, the inverter can be fitted with the Fronius Datamanager plug-in
card (8).
Fronius developed Solar Net to make these system add-ons flexible and capable of being
used in a wide variety of different applications. Fronius Solar Net is a data network that
enables several inverters to be linked to the system add-ons.
Fronius Solar Net is a bus system with ring topology. Just one suitable cable is enough
for communication between one or more inverters connected to Fronius Solar Net and a
system add-on.
In order to clearly define each inverter in Fronius Solar Net, each inverter must also be
assigned an individual number.
You can assign individual numbers as per the "SETUP Menu" section.
Different system add-ons are automatically recognized by Fronius Solar Net.
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:
Error in the data communication in the Fronius Solar Net
- Overcurrent (current flow > 3 A, e.g. due to a short circuit in Fronius Solar Net ring)
- Undervoltage (no short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if too many
DATCOM components are in Fronius Solar Net and the electrical supply is insufficient)
In this case, an additional power supply is required for the Fronius DATCOM compo-
nents using an external power supply (43,0001,1194) on one of the Fronius DATCOM
components.
Check other DATCOM components to detect any undervoltage present.
After a shutdown due to overcurrent or undervoltage, the inverter tries to restore the energy
supply in the Fronius Solar Net every 5 seconds so long as there is an error.
Once the error has been corrected, power is restored to Fronius Solar Net within 5 sec-
onds.

External communication (Fronius Solar Net) takes place in the inverter via the data com-
munication area. The data communication area has two RS-422 interfaces: an input and
an output. RJ45 plug connectors are used to establish the connection.
IMPORTANT! Only one master Fronius Datamanager is permitted per Fronius Solar Net
Ring. Additional Fronius Datamanager slaves can be switched or removed (see section en-
titled "Controls and Indicators on Fronius Datamanager 2.0").
Unused option card slots can be closed by replacing the cover (item number
42,0405,2094), or an inverter without Fronius Datamanager (light version) can be used.
