So, regarding the best, or least worst, place to keep my expanding collection of battery storage gubbins, et al.

At the moment, all the PV & battery stuff is located in the attic roof space of my kitchen. A number of SE inverters plus some Lux LXP3600 units, Pylontech US2000/US2000C batteries, plus an increasing number of Chinese stack cells - current EVE280 and 230 units.

My house is quite old, being a former pub, and essentially L shaped. The main house has a ground floor extension (the former pub kitchen) it’s that roof space that the gubbins is all in.

I’m toying with the idea of moving it from the roof space to the cellar, which is under the middle of the main house. There are a number of reasons for this, but mainly stability of temperature and ease of access. The cellar would give me both these, whereas although the roof isn’t too bad for access, it does mean a bit of a climb with cramped working conditions and quite an extreme in temperature throughout the year. The cellar would have better usable space for future expansion without weight concerns and has very little variation of temperature throughout the year.

Yes, there would be the hassle of moving it all, but I’m not worried about that.

My main thoughts are fire related. If it were to “go up” at the moment then it would damage the kitchen extension for sure, but the main house would be untouched. If the same were to happen when all installed in the cellar then the main house would be in jeopardy.

There’s lots of stuff talked about Lithium Ion cells, but my understanding is that the Pylons and EVEs are lifepo4, without Cobalt. But, they could still burn - I think?

Hopefully this is sufficient info to gather comments, opinions etc.

There is a third option- which would be to build a “lean to” extension at the gable end of the L extension- brick built & house it all there. There wouldn’t be as much temp stability or space as the cellar option - but it would be viable, with perhaps a challenge in terms of ensuring temperature stability.

Thanks - Rob

I was planning my install for under the floor in the hall, but now think maintenance/commissioning will be far easier in my detached garage, more hassle for install but easier to monitor / repair.

What about an insulated lean too, timber frame/kingspan insulated type construction?

And it's above the kitchen, a high risk area anyway.

But fires go up, not down, so keeping the energy stores in a cellar means they are not as likely to provide additional risk in that, probably more likely scenario.
