Here's the most concise summary of what I know about power: 1. 90% of all power outages are less than 10 seconds. A UPS can handle that fine. 2. 9% of all power outages are between 10 seconds and a few hours. A UPS can handle that fine. 3. 1% (or less) of all power outages are multi-day outages. UPSs that can handle that are way more expensive than you can afford. Get a generator and use the UPS to cover the gap between when the outage starts and when the generator is providing clean power. Therefore... 4. If you can't afford a generator, get a UPS that lasts lonog enough to shut down your machines. ...and... 5. Because outages tend to be very small or very long, if you reach the 1-hour point, start powering off machines and send employees home.
