number of batteries or battery modules.
2.4 Voltage inside the storage system
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 storage system is switched off.
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 (see section 7.2).
Only then can the storage system be opened.

Installation Guide
Page 10 of 53
Even if the utility grid fails, the storage system will continue delivering
power. Before servicing the storage system:
Turn off the storage system.
Danger to life due to electric shock.
2.5 Prohibited uses
Do not use the storage system:
-In vehicles
-In standing water or (>90%) humidity locations
-In areas at risk of filling with combustible dust (flour dust, sawdust, etc.)
-In direct sunlight
-In locations with the air ammonia content exceeds 20 ppm
-In presence of corrosive gases
-In locations with elevations above 2,000 meters above sea-level
-In locations with ambient temperature outside -10°C - 50°C
2.6 Handling the battery modules
Figure 1: sonnenModule4 battery module
-The battery modules have a nominal voltage of 102.4 VDC and therefore fall into
the range of protected extra-low voltage (under 120 VDC).
-The battery modules are utilising high-performance Lithium-Iron-Phosphate (LFP)
-The battery modules contain no metallic Lithium.

Installation Guide
Page 11 of 53
WARNING – RISK OF ELECTRIC SHOCK
Residual voltage is always present on DC terminals, and the battery
modules cannot be turned off.
Avoid contact with terminals.
When working on the storage system:
-Take off metallic jewellery.
-Turn off the storage system.
-Use insulated tools.
-Wear personal protective equipment, including safety glasses, insulated
gloves, and safety shoes.
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.
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.

Installation Guide
Page 12 of 53
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
contents 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 main switch in the building.
If the storage system and/or main switch cannot be safely switched off:
Observe the minimum distances specified for the extinguishing agent used. The
storage system works with an output voltage of 230 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.
