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...

Here's some prosine 2.0 numbers:
DC output 14.1 volts @ 31 amps = 437 watts.
AC input: 5.0 amps @ 119.6 volts, VA calculated = 598, VA from kill-a-watt = 604
watts from kill-a-watt = 583, pf = .965, efficiency = 75% (not so good!)
However, looking at efficiency in terms of VA input compared to watts output, the prosine is 72.3%, where an 80% efficient converter with a 0.7 pf clocks out to 56%. Makes the prosine bad for an electric meter but good for a generator.
