For years, I have used a figure of .0785 gallons per KW per hour and it has been very accurate. Four rooftops on balanced legs will draw around 20A per leg.
20A X 240V = 4.8KW. Throw in an occasional refrigerator load or water pump (Head Hunter) and likely round up to 5KW. That times the factor results in .390 gallons per hour.
That load requires a bit over 8HP from the engine. The Yanmar fuel consumption rate is .39lb/HP-hr. That works out to be .43 gallons so the .39 figure is close.
I'm too windy !!
