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...

A PD 60 amper at 14.4v will have 864w output at max. With the reputed 70% for PDs, that would require 100/70 x 864 = 1234 VA from generator.
I don't know where they got that 1000w input spec.
EDIT, I see the 9200s claim at least 80% for efficiency, so 100/80 x 864 = 1080. If 1000 VA is the true input and 864 is output, efficiency must be 86.4 if I did that right, which is in line with PowerMax's claim of at least 85%. I don't know how to resolve PD's claim of 80 with the 0.70 PF that has come up on here many times in the past.
Past looks at various brands' spec sheets has been an exercise in confusion wrt stated input requirements. They seem to generally understate the VA required.
If you do the output first as shown above, apply the efficiency, and derive the input for yourself, you will get much closer to the truth.
