PT---we need a press to talk button! :)
Working on the VA if I swap the 55 out for the 75, taking advantage of the 100 only doing 75.
Kill-A-Watt on the 55 doing 56.8a is 1383VA, 980w, PF 0.70
If that 55 were PF corrected (o.97 vs 0.70) then VA would be about 1010 but now with the 75 PF corrected that is 1241/97 = 1279
Meanwhile the Kill-A-Watt on the 75 is 1693VA (1241w. o.73OPF)
1693 + 1279 = 2972 VA ---Honda rated at 2800---but will do the 55 and 100 at 155 which is about 1383 + 1910 = 3293 (don't know how it can do that but it does---perhaps because the total is less than the sum of the parts due to the lower loaded voltage when both on there)
(It won't run the 55 and 75. 1383 + 1693 = 3076. Don't know why not.)
