Per Pianotuna’s request, here’s the readings he earlier asked for with the Air conditioner running:
All readings taken via Kill-a-Watt, ambient temp was at 63degF...
Honda, no load = 127v
With air cond load, but before Autoformer = 125v, 7.0 running amps, 803w
With air cond load, but after Autoformer = 127v, 6.9 running amps, 806w
Not a whole lot of apparent difference, but these were all running measurements versus locked rotor surge measurements...Surge intervals are too momentary to obtain a reliable measurement...
I think it’s ALL about the surge and voltage sag...JMO...
Tested three more times while in the Eco mode, and the genny recovered each time without a hitch...
Hope this helps,
