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. Country-specific regula-
tions concerning electrical installations must be observed at all times.
• 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 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.
2.3 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.

2 | Safety
6 / 28 Operating instructions sonnenBatterie hybrid 9.53
• 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.
2.4 Voltage in and on the storage system
The storage system contains live electrical parts, which poses a risk of electrical shock.
Therefore:
Do not open the storage system.
The plug-in connectors on the top side of the storage system are directly connected to
the PV generator of the PV system. This means, there is voltage present on the PV plug-in
connectors when the PV system generates electricity, even if the PV disconnector has
been switched off.
Therefore:
Do not disconnect the PV plug-in connectors at the top of the storage system.
2.5 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).
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.

KD-564 | 1001821 | EN | 03 7 / 28
2.6 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.

3.4 Function
3.4.1 Basic principle
Illustration1: sonnenBatterie function
1 PV system 4 Measurement of consumption
2 Storage system 5 Public electricity grid
3 Consumers in building (e.g. washing machine,
hob, lamps, refrigerator, etc.)
The storage system (2) is connected to the PV system (1) and the public electricity grid (5).
Furthermore the current consumption of the consumers in the building (3) is constantly
measured (4).
Generation > Consumption
If the generation of power is greater than the consumption, there is a surplus of electrical
energy. In this case as much as possible of this surplus is used to charge the battery of the
storage system.
If the entire portion of the surplus can not be charged into the battery, the remaining sur-
plus is fed into the public electricity grid.
Consumption > Generation
If the consumption is greater than the generation of power, there is a deficit of electrical
energy. In this case the battery is discharged to even out as much of the deficit as possible.
If the entire deficit can not be compensated by discharging the battery, the remaining de-
ficit is covered by the public electricity grid.

12 / 28 Operating instructions sonnenBatterie hybrid 9.53
3.4.2 Feed-in limit
PV systems are subject to a feed-in limit in some circumstances. The feed-in limit restricts
the PV system’s feed-in power at the mains connection point.
Example
• Nominal power of PV system: 10kWp
• Power limit: 50%
• Maximum feed-in power: 5kW
In this example, the feed-in power of 5kW must not be exceeded. The following figure
shows an example of the PV system’s production over the course of a day.
Illustration2: Example: feed-in limit at 50% of
nominal power
1 Charging of storage system
2 Switch-on of consumers via self-
consumption switch
3 Switch-on of consumers via
sonnenSmart plug
4 Midday peak, which must not be fed
into the electrical mains
To prevent production reduction – and therefore
energy loss – the excess energy is first stored in the
storage system(1) and consumption is increased by
switching on consumers(2,3). Production is only
reduced if these measures do not lead to the de-
sired limit.
Measures for limiting feed-in are explained in detail in the following. The individual meas-
ures are carried out one after the other. Only when one measure does not achieve the de-
sired reduction is the next measure introduced.
1. Charging of battery
Excess energy is directed to the storage system battery. In order for this to occur, there
must be sufficient storage capacity available in the battery.
2. Activation of the self-consumption switch
Consumers connected to the permanently wired switch output are switched on here.
3. Switch-on of consumers (via sonnenSmart plug)
The consumers are activated as soon as the feed-in limit is exceeded. The consumers are
deactivated again once the level has dropped below the limit and stayed there for at least
three minutes.
4. Reduction of PV power
Production is reduced via an integrated switch contact on the inverter. This limited the PV
inverter to a set power output. In order for this to occur, the inverter must support power
reduction using a switch contact or an external solution (e.g. a solar datalogger). Configur-
ation and connection are carried out by the electrician.

5.2.2 Dashboard page
The start page of the web interface (Dashboard) provides an initial overview of the current
status of your storage system. All of the energy flows are specified there in watts and clari-
fied with arrow indicators.
The current production of the PV system and the consumption of the electrical consumers
in the building are displayed in contrast with the storage system and the public electricity
grid. Usage from the public electricity grid is displayed when production and the electricity
available from the storage system are not sufficient to meet the energy needs of the build-
ing. Feed-in is displayed when there is sufficient electricity available to feed some into the
public grid within any existing feed-in limit.
The state of charge (SOC) of the battery modules is specified in relation to the storage
system and information as to whether the storage system is storing electricity (charging)
or providing electricity (discharging) is displayed.
5.2.3 System page
The System page provides technical background information on your storage system.
For example, you can see how many battery modules are installed (General Information >
Capacity) and what the maximum power provided by the inverters is (General Information
> Inverter Max. Power).
The other information, such as the serial number and model designation of your storage
system (each under General Information), may be necessary in the event of a fault, if you
contact the electrician performing the installation or the sonnen service team, for ex-
ample.
5.2.4 Inverter page
The Inverter page is where a self-test can be performed. This is necessary for inverters
commissioned in certain countries (including Italy).
Since this function is only required in certain regions, the test is only displayed if a corres-
ponding country code was selected for the inverter during commissioning.

5.2.5 Settings page
Depending on the configuration of your storage system, the following areas are displayed
on the Settings page:
Operating Mode
Operating Mode Self-Consumption is normally used.
The other two operating modes (Time of Use (time linking) and Battery-Module-Extension
(30%) (module extension)) are only required in certain cases and should only be set by the
electrician performing the installation.
Backup-buffer
If a sonnenProtect is connected to the storage system, the Backup-buffer field is dis-
played. You can select the backup buffer as a percentage here. This portion of the storage
capacity is then reserved for the backup supply, i.e. this portion of the capacity is not avail-
able to the storage system in normal operation.
Combined heat and power unit (CHP)
If a CHP with constant power output is connected to the storage system and has been set
up appropriately by the installer, the Combined Heat and Power (CHP) field is displayed.
The Power specifies the constant power of the CHP and should not be changed after initial
configuration by the installer. The lower limit of the charging state at which the CHP is ac-
tivated (Charge state to start CHP) and the upper limit at which the CHP is stopped
(Charge state to stop CHP) are specified as percentages.
Contact your installer before changes are made to the settings.
