2 Safety
2.1 Intended Use
The sonnenBatterie hybrid 9.53 is a battery storage system which can be used to store
electrical energy. Improper use of this system poses a risk of death or injury to the user or
third parties as well as damage to the product and other items of value. The following
points must therefore be observed in order to comply with the intended use of the prouct:
• The storage system must not be installed in any kind of combination.
• The storage system must be fully installed in accordance with the installation instruc-
tions.
• The storage system must be installed by a licensed electrician.
• The storage system is only allowed to be operated with PV generators of Class A rating
according to IEC 61730.
• The storage system must only be used at a suitable installation location.
• The transport and storage conditions must be observed.
Especially the following uses are not permissible:
• Operation in flammable environments or areas at risk of explosion.
• Operation in locations at risk of flooding.
• Operation outdoors.
• Operation of the battery modules outside of its storage system.
Failure to comply with the conditions of the warranty and the information spe-
cified in this document invalidates any warranty claims.
2.2 Requirements for the electrician
Improper installation can result in personal injury and/or damage to components. For this
reason, the storage system must only be installed and commissioned by licensed electri-
cians. Licensed electricians must meet the following criteria:
• The electrician must be a person with a technical knowledge or sufficient experience to
enable him/her to avoid dangers which electricity may create.
• The electrician must has successfully completed the sonnen Australia installer training
and have valid installer accreditation at the time of installation.
2.3 Operating the storage system
Incorrect operation can lead to injury to yourself or others and cause damage to property:
• The storage system must only be operated as described in the product documentation.
• This device can be used by children from the age of eight (8) years old and individuals
with impaired physical, sensory or mental capabilities or individuals with limited know-
ledge and/or experience of working with the device, as long as they are supervised or
have been trained to safely use the device and understand the resulting risks of doing so.
Children must not play with the device. Cleaning and user maintenance must not be car-
ried out by children without supervision.

Safety | 2
KD-504 | 22355 | EN | X02 7 / 64
2.4 Product modifications or changes to the product environment
• Only use the storage system in its original state - without any unauthorised modifica-
tions - and when it is in proper working order.
• Safety devices must never be overridden, blocker or tampered with.
• The interfaces of the storage system must be wired in accordance with the product doc-
umentation.
• An appropriate and readily accessible disconnect device shall be incorporated in the
fixed wiring.
• All repairs on the storage system must be performed by authorised service technicians
only.
• The replacement of battery modules must be performed by authorised service techni-
cians only. When replacing batteries, replace with the same type and number of batter-
ies or battery modules.
2.5 Voltage on and in the storage system
5 min
The storage system contains live electrical parts, which poses a risk of electrical shock. The
storage system inverter also contains capacitors which carry voltage even after the stor-
age system is switched off.
The PV generator of the PV system is directly connected to the storage system through
the plug-in connectors on the top side of the storage system. This means, there is voltage
present on the PV plug-in connectors when the PV system generates electricity, even if
the storage system has been switched off to electrically isolate it. Therefore:
Switch off the storage system to electrically isolate it before carrying out any work
(see Switching the storage system off to electrically isolate it [P.57]).
Only then can the storage system be opened.
2.6 Handling the battery modules
The battery modules installed in the storage system are protected by multiple protective
devices and can be operated safely. Despite their careful design, the battery cells inside
the battery modules may corrode or experience thermal runaway in the event of mechan-
ical damage, heat or a fault.
This can have the following effects:
• High heat generation on the surface of the battery cells.
• Electrolyte may escape.
• The escaping electrolyte may ignite and cause an explosive flame.
• The smoke from burning battery modules can irritate the skin, eyes and throat.
Therefore, proceed as follows:
Do not open the battery modules.
Do not mechanically damage the battery modules (pierce, deform, strip down, etc.)
Do not modify the battery modules.
Do not allow the battery modules to come into contact with water (except when extin-
guishing a fire in the storage system).

2 | Safety
8 / 64 Installation instructions sonnenBatterie hybrid 9.53
Do not heat the battery modules. Operate them only within the permissible temperat-
ure range.
Keep the battery modules well away from sources of ignition.
Do not short-circuit the battery modules. Do not allow them to come into contact with
metal.
Do not continue to use the battery modules after a short circuit.
Do not deep-discharge the battery modules.
In the event that module contents are released:
Do not enter the room under any circumstance.
Avoid contact with the escaping electrolyte.
Contact the fire services.
2.7 Conduct in case of a fire
Fire may occur with electrical equipment despite its careful design. Likewise, a fire in the
vicinity of the equipment can cause the storage system to catch fire, releasing the con-
tents of the battery modules.
In the event of a fire in the vicinity of the product or in the storage system itself, proceed
as follows:
Only firefighters with appropriate protective equipment (safety gloves, safety clothing,
face guard, breathing protection) are permitted to enter the room where the burning
storage system is located.
There is a danger of electrocution when extinguishing fire while the storage system is
switched on. Therefore, before starting to extinguish the fire:
Switch off the storage system to electrically isolate it.
Switch off the mains fuses in the building.
If the storage system and/or mains fuses cannot be safely switched off:
Observe the minimum distances specified for the extinguishing agent used. The stor-
age system works with an output voltage of 230 V (AC) and is therefore considered a
low-voltage system. However, the voltage of the PV system that is connected to the
storage system (through the PV connectors on the top of the storage system) can be
up to 750 V (DC).
• A storage system fire can be extinguished using conventional extinguishing agents.
• Water is recommended as an extinguishing agent in order to cool the battery modules
and therefore prevent thermal runaway in battery modules which are still intact.
Information on the battery modules:
• The battery modules have a nominal voltage of 48 V (DC) and therefore fall into the
range of protected extra-low voltage (under 60 V DC).
• The battery modules do not contain metallic lithium.
