Speaking as someone who is running off of a generator now, they aren't as
bad as I thought. I'm able to run everything off of this 6kva generator I
rented localy. The power is clean enough to run everything, and I'm able to
go about 8 hours on 5 gallons of gas, powering 12 servers, two DSU's, two
routers, and two monitors.
However... You need something that'll carry everything for enough time to
get the generator to start, and something that can decide when the time is
right to shut the generator back off.
There are companies that make eternal power systems like that, but I can't
think of any names off the top of my head.
