7
EN

For the location of the safety and danger notices on the device, refer to the section
headed "General remarks" in the Operating Instructions for the device.
Any equipment malfunctions which might impair safety must be remedied before the
device is turned on.
This is for your personal safety!
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 shall not be held liable for any
damage arising from such usage.
Qualified person-
nel
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 quali-
fied personnel.
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 an authorised specialist.
It is impossible to guarantee that bought-in parts are designed and manufactured to meet
the demands made on them, or that they satisfy safety requirements. 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 temperature con-
trol 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 emis-
sions, it may affect the application area for which it was designed (e.g. when there is
sensitive 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.
Emergency
power
This system is equipped with an emergency power function. This means a backup power
supply is automatically established in the event of a power outage.
The emergency power sticker provided with the inverter must be attached to the elec-
trical distributor.
8

For maintenance and installation work, the system must both be isolated from the grid,
and backup power mode must be disabled by opening the integrated DC disconnector
on the inverter.
The emergency power supply is automatically activated and deactivated depending on
the insolation conditions and the state of charge of the battery. This means that emer-
gency power can be re-established unexpectedly when in standby mode. For this
reason, when the emergency power supply is deactivated, switch off all connected
devices and do not undertake any installation work on the household network.
Disposal To comply with the European Directive 2002/96/EC on Waste Electrical and Electronic
Equipment and its implementation as national law, electrical equipment that has reached
the end of its life and dead batteries must be sorted from general waste 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 envir-
onment and your health!
If you need to replace your Fronius Solar Battery at some point, Fronius will take back
the old device and arrange for it to be recycled in an appropriate manner.

The hybrid inverter converts 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. In addition, the solar energy can be stored in a connected battery for
later use.
The hybrid inverter has been developed specifically for use in grid-connected photovol-
taic systems. Emergency power mode is possible provided that appropriate wiring has
been installed.
Thanks to its design and operating principle, the inverter is extremely safe both to install
and to operate.
The inverter monitors the public grid automatically. 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 voltage, frequency and islanding detection monitoring. The
inverter switches to emergency power mode provided that appropriate wiring has been
installed.
Operation of the inverter is fully automatic.
The inverter is designed to draw as much power from the solar modules as possible.
Depending on the operating point, this power is either stored in the battery, fed into the
grid or used for the household network in emergency power mode.
As soon as the solar modules stop providing sufficient energy, the power from the battery
is fed into the household network. Depending on the selected setting, power can also be
drawn from the public grid for the purpose of charging the battery.
If the inverter becomes too hot, it automatically reduces the current output power or char-
ging power, or switches to emergency power mode 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 suit-
able heat dissipation).
IMPORTANT! The battery is only to be switched on when the inverter is in Standby
mode.

Proper use The solar inverter is exclusively intended for charging a battery with direct current from
solar modules, or for converting this direct current into alternating current and feeding it
into the public grid or the household network in emergency power mode.
The following actions constitute improper use:
- Any use above and beyond this purpose
- Making any modifications to the inverter that have not been expressly approved by
Fronius
- Installing components that are not distributed or expressly approved by Fronius
- Operating the device with a battery that has not been approved by Fronius
- Operating the equipment with an energy meter that has not been approved by
Fronius
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.
Proper use also includes:
- Carefully studying and obeying the Installation and Operating Instructions
- Performing all stipulated inspection and maintenance work
When designing the photovoltaic system, ensure that all of its components are operated
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.
Observe the stipulations of the power supply company concerning energy fed into the
grid, emergency power mode and the operation of storage systems.
The Fronius Symo Hybrid is a grid-connected inverter with an emergency power function
– it is not a stand-alone inverter. The following restrictions must therefore be observed in
emergency power mode:
- Emergency power mode may be in operation for at least 1500 hours
- Emergency power mode may be in operation for more than 1500 operating hours if
15% of the duration of the inverter's grid power feed operation is not exceeded at
the relevant time

With the market launch of its new Fronius Energy Package, Fronius is introducing an
inverter that can be used to store energy. One of the key components is the Fronius
Solar Battery, which contains a lithium-ion rechargeable cell. The Fronius Solar Battery
supplements the Fronius hybrid inverter by adding storage functionality. This means that
the solar energy from the solar modules can be stored for later use.
The storage system is only suitable for operation in conjunction with Fronius hybrid
inverters.
Thanks to its design and operating principle, the storage system is extremely safe both
to install and to operate. A high-performance lithium-ion phosphate battery is used (LiFe-
PO4), which is based on the latest technology and complies with the highest safety
standards.
When used in conjunction with the Fronius inverter, operation of the storage system is
fully automatic.
If proper charging of the batteries in the Fronius Energy Package cannot be guaranteed
for an extended period of time (over several weeks or months) for any reason, we
strongly recommend that the following steps are undertaken to prevent the deep dis-
charge of the battery modules:
- switch off the main switch of the Fronius Solar Battery
- remove the DC fuses from the fuse holder
- remove the orange power connector from the individual battery modules
Proper use The Fronius Solar Battery is exclusively intended for taking direct current from a Fronius
hybrid inverter and storing it for later use.
The following actions constitute improper use:
- Any use above and beyond this purpose
- Making any modifications to the storage system that have not been expressly
approved by Fronius
- Installing components that are not distributed or expressly approved by Fronius
- Operating the system with an inverter that has not been approved by Fronius
- Operating the equipment with an energy meter that has not been approved by
Fronius
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.

EN

Proper use also includes:
- Carefully studying and obeying the installation and operating instructions
- performing all stipulated inspection and maintenance work
Observe the stipulations of the power supply company concerning energy fed into the
grid and the operation of storage systems.
Increase in stor-
age capacity
The storage capacity of the Fronius Solar Battery can also be increased after purchase
to a maximum capacity of 9.6 kWh of usable energy.
The capacity is increased by adding additional battery modules and this must be carried
out by a qualified electrician.
Capacity can be expanded within 2 years from the date of purchase, but a maximum of
30 months following dispatch from Fronius Austria.
The capacity cannot be increased after this for technical reasons. Observe the stipula-
tions of the distribution network operator concerning energy fed into the grid and the
operation of storage systems.
State of charge
(SOC) accuracy
Adding or replacing a memory module can lead to inaccuracies when calculating the
state of charge (SOC). Straight lines and jumps can occur, in particular immediately after
the upgrade. These only affect the display of the state of charge and do not affect opera-
tion of the device.
