Disposal
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 perform any actions other than those described in the documentation.
This applies even if you are qualified to do so.
All cables and leads must be secure, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or inadequately dimen-
sioned cables and leads must be immediately repaired by authorised person-
nel.
Maintenance and repair work must only be carried out by authorised person-
nel.
It is impossible to guarantee that bought-in parts are designed and manufac-
tured to meet the demands made of them, or that they satisfy safety require-
ments. Use only original spare parts (also applies to standard parts).
Do not carry out any modifications, alterations, etc. to the device without the
manufacturer's consent.
Components that are not in perfect condition must be changed immediately.
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 tem-
perature 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 installa-
tion situation, the power quality, the surrounding walls and the properties of
the room in general.
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 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 situ-
ation.
To comply with the European Directive 2002/96/EC on Waste Electrical and
Electronic Equipment and its implementation as national law, electrical equip-
ment 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 either be returned to your dealer or given to
one of the approved collection and recycling facilities in your area. Ignoring
this European Directive may be harmful to the environment and your own
health!
If you need to replace your battery at some point, Fronius will take back the
old device and arrange for it to be recycled in an appropriate manner.

Fronius Symo Hybrid
Device concept Device design:
(1) Housing lid
(2) Inverter
(3) Wall bracket
(4) Connection area including DC main
switch
(5) Data communication area
(6) Data communication cover
The hybrid inverter converts the direct current generated by the solar modules into alter-
nating 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 Fronius Solar Battery
for use later on.
This version of the hybrid inverter is only intended for use in grid connected photovoltaic
systems. A device update is required from the manufacturer in order to generate power
separately from the public grid. As well as providing functional enhancements for the hard-
ware and software, this update also includes relevant user documentation.
The hybrid inverter is delivered ready for supplying emergency power.
Thanks to its design and the way it works, 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.
Operation of the inverter is fully automatic.
The inverter is designed to get as much power out of the solar modules as possible.
Depending on the operating point, this power is either stored in the battery or it is fed into
the grid.
As soon as the solar modules stop providing sufficient energy, the power from the Fronius
Solar Battery is fed into the home network. Depending on the selected setting, power can
also be drawn from the public grid for the purpose of charging the battery.
If no power is available from the solar modules and no power is being drawn from the bat-
teries, the inverter disconnects the power electronics from the grid completely and ceases
operating. It retains all its settings and stored data.
If the inverter becomes too hot, it automatically reduces the current output power or current
charging 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).
(1) (2) (3)
(4)(5)(6)
IMPORTANT! The Fronius Solar Battery is only to be switched on when the inverter is in
Standby mode.

14

With the market launch of its new Fronius Energy Package, Fronius is introducing an in-
verter 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 supple-
ments the Fronius Symo Hybrid by adding storage functionality as well. This means that
the solar energy from the solar modules can be stored for use later on.
The storage system is only suitable for operation in conjunction with Fronius Symo Hybrid
inverters.
Thanks to its design and the way it works, the storage system is extremely safe both to
install and to operate. It relies on a high-power lithium-ion rechargeable cell, which is based
on state-of-the-art iron phosphate (LiFePO4) technology and conforms to the highest safe-
ty standards.
When used in conjunction with the Fronius inverter, operation of the storage system is fully
automatic.
Proper use The Fronius Solar Battery is exclusively intended for taking direct current from a Fronius
Symo Hybrid inverter and storing it so that it can be used later on.
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 ap-
proved 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.
Proper use also includes:
- Carefully studying and obeying the installation and operating instructions
- Performing all stipulated inspection and maintenance work
