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.
