Safety
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 (see 8.2 – p. 62).
►
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 storage system works with an output voltage of 400 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 1,000 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 51.2 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.
