Petrol

— the fuel used by most modern generators — at least low and medium power. Gasoline engines are simpler and cheaper than diesel engines, moreover, they are not so difficult to maintain and repair. Their operation is somewhat more expensive due to the price of gasoline, however, with a relatively infrequent use of the generator, this moment is not critical. But for long-term continuous operation at high power, such engines are poorly suited; so that generators with more than 20 kW of rated power are not made gasoline. In general, such models are good for occasional use, as well as backup power sources for low power electrical systems.
