► Read through this document and all further applicable documents carefully,
paying special attention to the chapters on safety and warnings.
2.3.2 Danger to life due to explosive and flammable materials
► Do not use the storage system in potentially explosive environments.
2.3.3 Danger to life due to product modifications or changes to
the product environment
► Never block or bypass the protective devices.
► Never modify the protective devices.
► Do not make changes to the storage system.
► Do not make changes to the electrical and data supply lines.
2.3.4 Danger of injury and risk of material damage due to improper
repairs
► Never attempt to repair the storage system yourself.
► Have faults and damage fixed by an authorised service technician.
► The replacement of battery modules must be performed by authorised service
technicians only.
2.3. Conduct in case of a fire / Important information for fire
services
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 contents of the battery modules.
► Observe the warnings about the risk of injury/burns due to the escape of
electrolyte (see section .5 – pg. 8).
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.
► Switch off the mains fuses in the building.
KD- 5 | Part no. 5 186 | EN | X04 7 / 6

2
Safety
If the storage system and/or mains fuses cannot be safely switched off:
► Observe the minimum distances specified in DIN VDE 013 for the
extinguishing agent used.
The storage system works with an output voltage of 30 V (AC) and is therefore
considered a low-voltage system.
► 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 51. 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.
2.4 Regulations (directives, laws, standards)
► Observe all relevant, currently applicable national regulations, especially the
regulations of the local power supply companies. The authorised electrician is
responsible for knowing and observing all of the regulations relevant to their work.
2. Warnings
This section contains specific warnings that must always be observed when working
with the product.
Danger to life due to electrocution!
Touching components inside the storage system poses a danger to life due to
electrocution.
► Do not touch any components.
► Do not remove any plastic covers.
► Never reach below covers.

Risk of injury and burns due to the escape of electrolyte
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 mechanical 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 extinguishing a fire in the storage system).
► Do not heat the battery modules. Operate them only within the permissible
temperature range.
► 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.
Deep-discharge of the battery modules
Destruction of the battery modules!
► Do not disconnect the storage system from the public grid for long periods of
time.
► Never continue to operate battery modules which have been deep-discharged.

Figure 1: sonnenBatterie function
The storage system ( ) constantly measures the current power generation of the
PV system1 (1) and the ongoing consumption (5) in the building.
Generation > consumption
If the generation of power is greater than the consumption, the surplus power
(difference between generation and consumption) is stored in the storage system.
The battery is charged.
For example, if 3000 watts are generated and 1700 watts are consumed, the
battery is charged with a power of 1300 watts.
Consumption > generation
If the consumption is greater than the generation of power, the deficit (difference
between consumption and generation) is provided by the storage system. The
battery is discharged.
For example, if 3500 watts are consumed and 000 watts are generated, the
battery discharges a power of 1500 watts.

. .2 Analysis of power diagram
Given the high density of information, analysis of a power diagram is not too
simple. For better understanding, some points in time of a power diagram are
analysed in what follows.
The example below shows how it works in a facility with limitation of the feed-in to
the public grid. This power limitation is a special feature that is used only in cases
where the network owner demands it. If requirements are imposed on such an
feed-in limitation, it can be controlled by the storage system.
13467
28
Figure 4: Analysis of power diagram
1 It is dark (no generation (yellow)). Consumption (blue) and discharging (red) have the
same value. Consumption is therefore covered by the discharging of the storage system.
Generation (yellow) is approx. 1000 watts. This is used to cover consumption (blue). The
intelligent charging management system has postponed charging; the charging buffer is
needed to avoid breaching the feed-in limit. The energy that is not required is fed into
the grid.
3 Generation has increased to approx. 3300 watts. This is used to cover consumption
(blue) and charge the storage system (green) at a minimal level. Charging with higher
power is prevented by the intelligent charging management system. This function
ensures that storage capacity is kept free in order to store part of the midday peak in the
storage system later.
4 Consumption (blue) exceeds generation and must be supplemented by the storage
system.
5 A breach of the feed-in limit is no longer expected. PV generation covers consumption
(blue) and the surplus is stored in the battery (green) so that it will be fully charged by
evening.
KD- 5 | Part no. 5 186 | EN | X04 19 / 6

Internet portal
6 From this point PV generation is no longer sufficient to cover consumption. The
difference is discharged from the storage system.
7 The storage system discharge (red) covers total consumption.
8 The storage system is discharged and consumption is covered by usage from the public
grid.
. .3 Analysing pie charts
Two pie charts are shown below the power graph.
The pie charts always refer to the time frame shown in the power graph.
Generation pie chart
Generation, shown in yellow,
symbolises the electrical power gained
by the generator in the analysed time
frame.
The fed-in power is marked in light
yellow in the chart.
The dark yellow part represents self-
consumption.
Self-consumption is the part of the
generated power that has not been fed-
in, but has instead been stored
temporarily in the battery or consumed.
Consumption pie chart
Consumption, shown in blow,
symbolised the power that was required
in the building during the analysed time
frame.
Purchased power (taken from the
mains) is marked in light blue in the
chart. The dark blue part represents
self-production.
Self-production is the part of the
consumed energy that was not taken
from the mains.
