Supermarkets rely on just in time deliveries. We learnt during COVID that even a slight delay can cause problems. Enough people then panic buy to snowball it.
It would take remarkably few road closures to leave towns isolated from supply chains. A 72 hour buffer is very useful in those cases. Even if it’s just to relieve short term pressure on those supply chains when they reconnect.












I’ve actually got one myself. I would have to get creative to get it recharged from my solar panels. The inverter is grid tied, and would need to be bypassed.
The original comment was talking about having a server up. That, and the networking kit to make it useful, would draw quite a bit. A lot more than you would get with a portable solar panel in the UK. To keep that up would require significant panels and storage capability, which implies fixed solar. Hence my comment warning them.
I know a few people who thought they would be fine in a power cut, due to having solar. I set them straight on that, before it caught them flat footed at least.
