Note: The Kill-A-Watt was blinking on shore power too but only after amps got to 15.1, so it is not to do with the red flashing overload lamp on the gen when it blinks. KAW rated to 15a so must be a safety thing it has for itself.
--------------
Got fresh 87 for the gen, still get the flashing red running the 75 amper doing battery charging but not when doing supply at 75 amps.
Supply KAW with charger at 75 amps
119v, 13.65a, 1137w, 1625VA, 0.70PF didn't take battery voltage. No flashing red on gen
Battery Charging at 75 amps (AGM 250AH battery at 73%--12.7v)
118v, 14.49a, 1247w, 1715VA, 0.73PF output 75 x 14.2 rising, red lamp flashing on gen. KAW not blinking.
wait a bit then,
117v, 14.93a, 1278w, 1741VA, output 75 x 14.4 battery
then 116.8 and 15.01 blinking
So that does show rising VA with rising battery voltage during the recharge. I can't do a long run of that with the 75, but could with the 55. I don't think I need more proof there though.
The red flashing on the gen does not mean the output 120 is intermittent, that was just the Kill-A-Watt.
The KAW does show the inverter in the gen doing its "amps creep" as loaded AC voltage drops with the increased load in VA. Same action as an inverter on DC running an AC load, where DC amps go up as battery voltage supply to the inverter falls the longer the 120v load stays on.
The gen manual does not mention the red flashing light, just that the gen will shut down output when overloaded and there is a reset button for that. I don't know if the gen engine would conk out at some point of overload too. My Honda 3000 did with a cold start and too soon hit with a big load. B&S "tech support"= "customer phone guy with no clue" never heard of the flashing red and his supervisor said maybe there was something wrong with the unit.
I think the flashing red is an "early warning" of overload and if you keep going then it will shut down. Don't know (yet?). Anyway I don't like to keep running the 75 with that light flashing, so I will use the 55 when that happens.
Obviously I should have bought the Honda 2200 instead with its 1800VA. Only three times the money! :)
