efficency and inverter generators
Hi, If I am going to run a Yamaha 3000 Sieb generator, is it more efficient to use it at nearly the maximum output, or is it better to stay at 50% or below? I want the most watts per gallon I ca...

With all those disclaimers, the general result was that the load level didn't make a whole lot of difference in fuel consumption.
1,600 watt load: Run time 2.97 hours/gallon. 4.75 kWh/gallon, RPM = 4,300
465 watt load: Run time 8.92 hours/gallon. 4.15 kWh/gallon, RPM = 3060
555 watt load: Run time 8.06 hours/gallon. 4.47 kWh/gallon, RPM = 3150
What am I missing here....yes, the EFFICIENCY stays pretty constant at 4.xx kWh/gal, but the CONSUMPTION varies with the load according to your results, ie, the 1600w load uses 3x the fuel compared to the 465 watt load.
I don't think you're missing anything. The question was how to get the most watts per gallon; loaded or not. Seems that it doesn't make much difference. Efficiency is more or less constant, you'll use fuel in direct relationship to the wattage you use.
