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...

Actually the VA should be lower for running both 100 and 55 together than you get by adding each one's VA? The loaded voltage would be lower with the higher load. Also that would make for a lower input amps?
I did some math but not sure it is right but the VA was still above 2800 at around 3100 if so.
Looking at Mr Wizard's 75 amper's VA compared with mine, and his lower input voltage and amps for the same output amps. However mine was set to 14.8v while his was set to 14.4 if that counts as higher output making that much difference in VA required..
Another thing is the way converters can keep up their amps with a lower voltage input to some degree before amps out fall off with too low an input. This means a lower input would be a lower VA required for the same amps out within that range.
It seems possible from all these KAW results to get an idea what gen will run what converter, but you can't fine-tune it. The available gen specs and the converter specs are so broad brush, and also because each will operate wIthin a fairly wide zone "depending."
Hard to pin this down and come up with a rule of thumb like say, " 25 VA per Amp of output" My KAW results go from 19 VA/Amp for the PF corrected, 22-25 for PF 0.7s to 25-28 for PF 0.6s
