The Importance of UL 9540A Fire Safety Testing for Energy Storage Systems 

Very informative thank you

While I understand your video, the UL standards seem to be in conflict with NFPA 855. The UL9450 and UL9450A are meant to demonstrate how fire "resistant" the batteries, and battery/enclosure/inverter combo behave in real life. However, the NFPA approaches batteries as a combustible pile. So the size is limited to 20 kW per cluster for a residence. This would mean the 6 and 12 capacity enclosures do not comply. Furthermore, NFPA 855 says that battery clusters or units must be 3 feet away from walls and each other, not to mention combustible materials. And fire suppression by water or other material is highly desired. So how would your current cabinets and even wall mounts comply with NFPA 855?
