Fitting the inverter mounting bracket
Safety
WARNING! An electric shock can be fatal. Danger due to residual voltage in capacitors. Wait for the capacitors to discharge. The discharge time is five minutes.
CAUTION! Risk of damage to the inverter from dirt or water on the terminals and
contacts of the connection area.
When drilling, ensure that terminals and contacts in the connection area do
not become dirty or wet.
Without a power stage set, the mounting bracket does not conform to the protection class of the inverter as a whole and so must not be installed without
the power stage set.
The mounting bracket should be protected from dirt and moisture during installation.
NOTE! Degree of protection IP 65 is only applicable if
the inverter is placed in the mounting bracket and permanently attached using screws
the cover for the data communication area is permanently attached to the inverter with screws.
Degree of protection IP 20 applies to the mounting bracket with no inverter.
Selecting wall
plugs and screws
IMPORTANT! Different fixings may be required to fit the mounting bracket depending on
the type of underlying surface. Fixings are therefore not included in the scope of supply of
the inverter. The installer is responsible for selecting the right type of fixing.
Recommended
screws
To install the inverter, the manufacturer recommends the use of steel or aluminium screws
with a diameter of 6 - 8 mm.
Opening the inverter
WARNING! An inadequate ground conductor connection can cause serious injury or damage. The housing screws provide a suitable ground conductor connection for grounding the housing and must NOT be replaced by any other screws
that do not provide a reliable ground conductor connection.

Type of AC cable
The following types of AC cable can be connected to the AC terminals of the inverter:
Cu / Al
Connecting aluminum cables
Cu
-
copper or aluminium: round, single wire
Copper: round, finely stranded up to conductor category 4
The AC-side terminals are designed for connecting single-wire, round, aluminum cables.
The following points must be taken into account when connecting aluminum cables due to
the non-conducting oxide layer of aluminum:
Reduced rated currents for aluminum cables
The connection requirements listed below
NOTE! Take into account local specifications when configuring cable cross sections.
Connection Requirements:
1
Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife.
IMPORTANTDo not use brushes, files or sandpaper. Aluminum particles may get stuck
and can transfer to other cables.
2
After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid- and
alkali-free Vaseline.
3
Then immediately connect it to the terminal.
Repeat the steps above whenever the cable is disconnected and then reconnected.
Cross-section of
the AC cable
When using a standard M32 metric screw joint with reducer:
cable diameter 7 - 15 mm
When using an M32 metric screw joint (reducer removed):
cable diameter 11 - 21 mm
(with a cable diameter of 11 mm the strain-relief force is reduced from 100 N to a maximum
of 80 N)
With cable diameters greater than 21 mm, the M32 screw joint must be replaced by an M32
screw joint with a larger clamping area - item number: 42,0407,0780 - strain-relief M32x15
KB 18-25.
Connecting the
inverter to the
public grid (AC)
26
NOTE! Form loops with the AC cables when connecting them to the AC terminals.
When securing the AC cables using a metric screw joint, ensure that the loops do
not protrude beyond the connection area. Otherwise, under certain circumstances it may no longer be possible to close the inverter.
IMPORTANT! The PE ground conductor of the AC cable must be laid in such a way that it
is the last to be disconnected in the event that the strain-relief device should fail.
This can be ensured, for example, by making it somewhat longer and by laying it in a loop.

If AC cables are laid over the shaft of the DC main switch or across the connection block
of the DC main switch, they may be damaged when the inverter is swung in, or they may
even prevent the inverter from being swung in.
IMPORTANT! Do not lay AC cables over the shaft of the DC main switch or across the connection block of the DC main switch.
27
EN
NOTE!
Ensure that the grid neutral conductor is grounded. This may not be the case
for IT networks (insulated networks with no grounding); it will then not be possible to use the inverter.
In order to use the inverter, the neutral conductor must be connected.
A neutral conductor that is too small may adversely affect the grid power feed
operation of the inverter. The neutral conductor must therefore be the same
size as the other live conductors.
If overlength AC or DC cables are to be laid
in loops in the connection area, attach the
cables with cable ties to the eyelets provided on the top and bottom of the connection block.

NOTE! The solar modules connected to the inverter must comply with the IEC
61730 Class A standard.
NOTE! When photovoltaic modules are exposed to light they supply current to the
inverter.
General comments regarding
solar modules
30
To enable suitable solar modules to be chosen and to use the inverter as efficiently as possible, it is important to bear the following points in mind:
If insolation is constant and the temperature is falling, the open circuit voltage of the
solar modules will increase. The open circuit voltage must not exceed 1000 V. If the
open circuit voltage exceeds the specified values, the inverter will be destroyed and
no warranty claims will be entertained.
The temperature coefficients on the solar modules data sheet must be observed
More exact values for dimensioning the solar modules can be provided by suitable calculation programs, like the Fronius Solar.configurator (which can be downloaded from
www.fronius.com).
EN
NOTE! Before you connect up the solar modules you should check that the voltage specified by the manufacturer corresponds to the actual measured voltage.

Connecting aluminum cables
The DC-side terminals are designed for connecting single-wire, round aluminum cables.
The following points must be taken into account when connecting aluminum cables due to
the non-conducting oxide layer of aluminum:
Reduced rated currents for aluminum cables
The connection requirements listed below
NOTE! Take into account local specifications when configuring cable cross sections.
Connection Requirements:
1
Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife.
IMPORTANT Do not use brushes, files or sandpaper. Aluminum particles may get stuck
and can transfer to other cables.
2
After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid- and
alkali-free Vaseline.
3
Then immediately connect it to the terminal.
Repeat the steps above whenever the cable is disconnected and then reconnected.
31
Do not ground the
poles of the solar
modules
The Hybrid inverter is a transformerless device. The individual poles of the solar modules must not be grounded.

WARNING! An inadequate ground conductor connection can cause serious injury or damage. The housing screws provide a suitable ground conductor connection for grounding the housing and must NOT be replaced by any other screws
that do not provide a reliable ground conductor connection.
The side sections of the housing lid are designed to function as holding and carrying handles.
NOTE! For safety reasons, the inverter is fitted with a latch that prevents the inverter from being swung into the mounting bracket unless the DC main switch is
switched off.
Never attach the inverter to the mounting bracket or swing it in unless the DC
main switch is switched off.
Never use force to attach the inverter or swing it in.
The fastening screws in the data communication area of the inverter are used for securing
the inverter to the mounting bracket. Correctly tightened fastening screws are a prerequisite if proper contact is to be established between the inverter and mounting bracket.
CAUTION! If the fastening screws are not tightened correctly, then the inverter is
at risk of being damaged.
Fastening screws that are not correctly tightened can result in arcs occurring
when the inverter is in operation, which in turn can cause fires. Always use the
specified torque when tightening the fastening screws.

Run the Solar Web wizard and follow the instructions.
The Fronius Solar.web homepage
or
the Fronius system monitoring web page is displayed.
Information to
help you work
through the Solar
Web wizard
The solar web wizard consists of 5 steps:
1. General
General system data (e.g. system name) is entered here
2. Service password
Enter (and make a note of) the service password
3. IO assignment
Settings for the IO interface are entered (see also "Fronius Energy Package - IO assignment" Operating Instructions)
4. System overview
Settings for the entire PV system are entered (see also "Fronius Energy Package - System
overview" Operating Instructions)
5. Dynamic power
Settings for dynamic power reduction are entered (see also "Fronius Energy Package - Dynamic power reduction" Operating Instructions)
Once you have worked your way through the Solar Web wizard, an automatic process is
triggered to calibrate all the components. This involves charging the Fronius Solar Battery
fully. After that, the system automatically starts in the set operating mode.
This calibration charging process is also performed automatically during actual operation
after a number of charging and discharging cycles. When this calibration charge is performed depends on a number of different factors, such as the average state of charge or
the energy throughput through the battery. The time can therefore vary depending on the
time of year as well.
If the "permit battery charging from PSC grid" setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic system when operating under normal conditions. Depending on the insolation conditions and size of the systems
concerned, the charging process can take a very long time.
If the "permit battery charging from PSC grid" setting is activated, the calibration charging
process is performed by drawing a constant current from the photovoltaic system and DSO
(distribution system operator) grid.
IMPORTANT! The automatic process for fully charging the battery may result in energy being drawn from the DSO grid. The process can take several hours and cannot be aborted.
