if I had a Honda 2000 (I'm assuming Honda is one of the "other brands" you're referring to?) and it was sitting idling along at a real low rpm in ECO mode, if I suddenly dropped a 1900 watt load on it, it would handle it just fine, every time?The eu2000i is being elevated a bit too high here. If it's idling in eco mode (at 3,000 RPM) and you dump a 1,900 watt load on it, it will sound like it's dying a fast death for about 5 seconds until the engine is able to spool up to its maximum 5,000 RPM, and the voltage will drop to 90 or so during much of that time. Do the same thing with eco off (4,300 RPM idle) and the story will be pretty much the same except the 5 seconds might go down to 3 seconds. You're not likely to ever actually push 1,900 watts for any meaningful amount of time, however, because a typical eu2000i won't do it. They go cleanly through 1,800 watts but can't maintain the voltage much further. On mine, as the load increases past 1,800 watts, there's a point where adding load increases the current but pulls the voltage down such that the output power is declining. (This is all in the context pf pf=1 loads). The big difference I'm noting in this area between the Honda and Champ is that when hit with a big load increase, the Honda will hang in there and eventually recover, while the Champ drops offline.
