Environmental
conditions
Operation or storage of the device outside the stipulated area will be deemed as
not in accordance with the intended purpose. The manufacturer accepts no liab-
ility for any damage resulting from improper use.
Qualified per-
sonnel
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 carry out any actions other than those described in the documentation. This
also applies to qualified personnel.
All cables and leads must be secured, undamaged, insulated and adequately di-
mensioned. 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 an authorised special-
ist.
It is impossible to guarantee that bought-in parts are designed and manufac-
tured to meet the demands made on them, or that they satisfy safety require-
ments. Use only original spare parts (also applies to standard parts).
Do not carry out any alterations, installations, or modifications to the device
without first obtaining the manufacturer's permission.
Components that are not in perfect condition must be changed 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 temperat-
ure control system; this depends on the amount of converted power, the ambient
temperature, the level 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
emissions, it may affect the application area for which it was designed (e.g., when
there is equipment that is susceptible to interference at the same location, or if
the site where the device is installed is close to either radio or television receiv-
ers). If this is the case, then the operator is obliged to take action to rectify the
situation.

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 cur-
rent generated by the solar modules
into alternating current. This alternat-
ing current is fed into the public grid
synchronously with the grid voltage.
The inverter has been developed exclusively for use in grid-connected photovol-
taic 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. Whenever conditions in the
electric grid are inconsistent with standard conditions (for example, grid switch-
off, interruption, etc.), the inverter will immediately stop producing power and in-
terrupt the supply of power into the grid.
The grid is monitored by monitoring the voltage, frequency and islanding condi-
tions.
The inverter operates fully automatically. As soon after sunrise as there is suffi-
cient 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 be-
ing too high or inadequate heat dissipation (e.g. if it is installed in a switch cabinet
without suitable heat dissipation).
Proper use/
intended pur-
pose
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.
15
EN

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 oper-
ated 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 meth-
ods and energy fed into the grid.
Warning notices
on the device
There are warning notices and safety symbols on and in the inverter. These warn-
ing 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.

AFCI - Arc Fault
Circuit Inter-
rupter (Arc
Guard)
AFCI (Arc Fault Circuit Interrupter) protects against arcing faults and in the nar-
rower sense is a protection device against contact faults. The AFCI evaluates any
DC-side faults that occur in the current and voltage curve with an electronic cir-
cuit and switches off the circuit when a contact fault is detected. This prevents
overheating on poor contacts and ideally possible fires.
CAUTION!
Danger due to incorrect or unprofessional DC installation.
The result is risk of damage and in turn, risk of fire to the PV system due to inad-
missible thermal loads that arise with an arc.
▶Check plug connections are in good condition.
▶Repair incorrect insulation as appropriate.
▶Complete connections as per the specifications.
IMPORTANT!
Fronius will not accept any costs associated with production downtimes, installer
costs, etc., that may arise as the result of a detected arc and its consequences.
Fronius accepts no liability for damage that can occur despite the presence of
the integrated Arc Fault Circuit Interrupter/extinguishing system ( e.g. caused by
a parallel arc).
17
EN

IMPORTANT!
Active PV module electronics (e.g., power optimiser) can impair the function of
the Arc Fault Circuit Interrupter. Fronius does not guarantee that the Arc Fault
Circuit Interrupter will work correctly in combination with active PV module
electronics.
Reconnection behaviour
After detection of an arc, feeding energy into the grid is interrupted for at least 5
minutes. Depending on the configuration, feeding energy into the grid is then
automatically resumed. If several arcs are detected within a period of 24 hours,
feeding energy into the grid can also be permanently interrupted until a manual
reconnection has taken place."

Data communication and Fronius Solar Net
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 en-
ables 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.
For instructions on how to assign a unique number, refer to the section SETUP
menu item.
Fronius Solar Net automatically recognises a wide variety of system add-ons.
In order to distinguish between several identical system extensions, each one
of them 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.froni-
us.com
