How Big a Gen to Run a Converter? Some Info.
EDIT: some of my earlier posts in this thread have the wrong idea. As more info came in later, things got less confusing--sort of! :) --------------------- Another look at this topic. It is n...

The 636 is 896VA*0.7PF = 627 watts
(The calculated watts (627) is a bit different than that read directly from the kill-a-watt (636))
i better go baack to school
to my way of thinking
it would be 533/(efficiency)/PF(0.7)
or 533/PF(0.7)=761.428/Efficiency = real actual input use
say efficiency is 70% PF = 0.7
output is 533w/0.7/0.70=1087 input
if Pf and efficiency are the same thing ?
then is 533/0.7= 761.428 watts input
power factor of 1.0 input = output
but that doesn't exist
and 636/889 =0.715 is that efficiency or power factor
are they one in the same, then its a simple one time equation
were does 627 come from..by trying to do a VA conversion ?
the problem as i see it is doing multiplication when its division
and all this ignores the facts
533w output
for
889w/va input
so real world conversion efficiency is 59.95%
aka 0.5995
55*14/0.6= 1283w input to get 770w charging
but those numbers don't match the users who say they can charge 55mps from a PD55 using a 1000w honda
