Honda 2000I versus Cpe 2000 inverter
I just weigh a Honda with full gas tank 53.2# Also weigh my cpe 2000 with full gas tank 55.6# I cannot tell the difference by lifting them For practical purposes they are the same heigh...

EDIT--ran a test on low amp output--results after this
-----------
Trying to follow Mr Wiz's example where it says 123.3 x 2.14 = 263.9VA
and then shows 170 Watts. So that would be 0.64PF like he says.
BUT--output is 49.6w (14.56 x 3.4) so at 85% efficiency, the input would be about 58 watts for the converter.
What else is on that gets that 170 watts vs 58?
-----------------
Looks like Mr Wiz is on to something (of course!) :)
Using the 75 amper, Kill-A-Watt, and Trimetric, unplugged shore power and have only converter on the P2200. Started with about 4 amps DC load on full batts, then about 13 amps, then about 24 amps.
(P2200 unloaded--125.4 volts)
124.7v, 1.17a, 82.6w, 139VA, PF 0.57, output 54.4w
123.3v, 3.70a, 268w, 413VA, PF 0.61, output 174w
122.0v, 6.45a, 455w, 696VA, PF 0.63, output 322w
So efficiencies were: 66% (54/83), 65%, 71% (322/455)
This seems to confirm Mr Wiz's observation that the converter is more efficient at higher amps. That might be from having a sort of internal fixed load to it so as output amps are higher, the internal fixed load is less in proportion?
----------
Even so, I got 54 vs 83 (66%) where he got 58 vs 170 (34%) so it still seems he had some other draw besides the converter, but as he also said , there are many possible factors.
