Finally I'm getting to the question. Does anyone know how critical =
cycling is? My clocks gained a little over 2 min during the 9 hour run =
so the cycle must be a little fast. Maybe 61 cycle? How critical is =
that for something as fussy as a computer for example?


I make it 60.222 Hz so not too bad. Computers will be fine with that.=20

Of more importance is the wave shape and the amount of noise the =
inverter puts out. Is it a nice clean sine wave or ? Noise spikes can =
sometimes travel through a power supply and cause problems for hard =
drives etc.=20

I'm an electronics engineer.

The ice storm took out my power this morning. I'm running on my generator as
I type. I agree some older generators might have an output that will confuse
a computors power supply.

I forgot to add.... Sometimes these inverters aren't very good at absorbing
spikes created by other equipment. I wouldn't recommend running something
like a vaccum cleaner, milling machine or inductive loads in general while
the power is out even it the total load is less than 5KW. Best think about
unplugging the computer first.
