I need to check if they are the same manufacturer as mine

Poor bloke, didn’t read if there was any fatality, but to have the house demolished……

Wonder if the insurance company will try and wriggle out with some obscure clause

Basement(ventilation) and boiler in same space

. Unlucky pal. Glad no one was injured.

That's only if a flammable gas was released from the cells. My money would be on a catastrophic energy release from a short-circuit. A gas explosion wouldn't necessarily damage the cells or leave a lot of "white smoke" - lithium oxide? (cf. beryllium oxide?)
I think it's common to have boilers in basements "abroad," together with washing machines, bike storage etc.

the battery energy storage system consisted of three battery packs from Shenzhen Basen Technology. He bought two in June 2022 and an additional one in June 2023 via the Alibaba platform. They are the “BR-48200B” and “MY-381” models, each with 10 kWh of capacity based on LFP technology housed in a 19-inch cabinet.

The battery system was coupled with a 15.47 kW photovoltaic system, which the homeowner was about to expand to 19.565 kW, and two different inverters: Victron’s Multiplus II 5000 and Solax X1 4.2. The cause of the explosion has yet to be clarified, and there were no electrical clues, according to the homeowner. Right before the accident, the battery’s state of charge (SOC) was 90.2% and the voltage stood at 52.41 V.

I read that too...
I didn't think it gave any useful info, except that the system was performing normally before the sudden blow-up. It will be interesting to hear the result of any investigation, I'll have to remember to do periodic searches.

Sounds like the system was under a decent load and discharging rather than a overcharging/TR event?

Makes sense.

That's exactly how our place is built. Over here in Austria and I suspect large parts of Germany when a building is built they have solid reinforced concrete basements that support the whole building. They do this because they have to dig below where frost will cause ground movement. Given that you have to have this space it makes sense to fill it with boilers, bikes etc as it isn't really living space.

I've been.in a couple. They were well.built and dry. Hell of an explosion to have done that. Likely had nowhere to go hence cratering the building. A window or two as weak points might have helped. I know thats 20/20 hindsight...
