And if that moment is during the night, you don't have it. If power outage is a part of your threat model, you want something that you can reliably switch to in a very short time and that will reliably provide the power you need for as long as you need to get the primary power supply back up.
- Xylakant 6y agoI could entirely scrape by without power at night for some time. Would it be inconvenient? Absolutely. Threatening? No. The little infrastructure I’d really need to run over night includes probably my fridge and my freezer and those could be powered by a battery backup for that time. There’s ready made modules for available for that (camping equipment level ready). Stove, oven, kettle not being available would be seriously annoying, but not threatening either. Intermittent power would be a massive improvement over no power at all.
- luckylion 6y agoRight, but you're not running a data center or factory. Individually, unless you're in very harsh climates, the safety margin for normal operations is huge. But that's not the case for complex systems. You can't simply shut down a data center for a week without turning it from a data center into some expensive building that currently provides zero value. Society relies on reliability. By extension, so do you, because without reliability in factories, there won't be solar modules, batteries and all the fancy gadgets being produced. Individually, you can easily survive a few days without power, or without food for that matter. But on a society level, that's a very different story.
