Quote from flytiger:
good god. Buy a generator. Keep all your plugs on surge protectors (I'm sure you've done that). You then only have to pull the surge protectors and plug, say, two lines into the generator. You're UPS will keep you up for only fifteen minutes or so.. Close out your trades. Hook the generator up, and boot back up. That way, if the outage is 2 or 3 hours, you're in business.
All you need is 1kw or up to run your computers. but you might as well get a bigger one. Pain in the ass, but that's life.
