Some differences between conventional and inverter generators lie in their sizes, weights and portability. Whereas conventional generators are bulky, hefty and difficult to carry around, inverter generators are compact, lightweight and easy to move from place to place. Inverter generators also tend to be more fuel efficient compared to conventional generators.
Conventional generators have been on the market for some time but the principle behind their operation basically remains the same. These machines usually run on gasoline, diesel or propane, which supplies power to a motor connected to an alternator that generates electricity. Inverter generators, meanwhile, are modern technological innovations that use cutting-edge electronic systems and state-of-the-art magnets. These highly-advanced devices typically comprise 3-phase generators that work by initially yielding alternating current. The AC output is then transformed into direct current, which is inverted back from DC into AC for a cleaner supply of electricity.
Since conventional generators are heavily built, larger fuel tanks can be installed inside these contraptions, which extend their run times. Inverter generators make up for their smaller fuel capacities and shorter run times by being more efficient than conventional versions. In terms of noise, inverter generators operate on a quieter level compared to conventional models.
Conventional generators have a maximum power output ranging from 500 to 50,000 watts or more, while inverter generators are commonly available in 1,000 to 4,000 watt units. With regards to the quality of the output power, inverter generators produce a significantly cleaner and far superior supply of electricity than conventional generators, according to Yamaha.
