Conventional Generators vs. Inverter Generators: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 16, 2023
Conventional generators produce AC power, are larger, and noisier, while inverter generators convert AC to DC then back to AC, are compact, and quieter.
Key Differences
Conventional generators, known for their straightforward mechanism, generate alternating current (AC) directly from the engine. This process contrasts with inverter generators, which utilize a rectifier to convert AC to direct current (DC) and then invert it back to a stable AC output.
Size and portability are significant differentiators; conventional generators are typically larger and heavier, making them less portable than the compact and lightweight design of inverter generators, which are designed for easy transportation.
When it comes to noise levels, conventional generators tend to operate louder due to their direct power production method and larger engines. Inverter generators, in contrast, are known for their quiet operation, making them suitable for varied settings, especially where noise is a concern.
Fuel efficiency is another crucial difference. Conventional generators run at a constant speed, often leading to higher fuel consumption. Inverter generators, however, adjust their engine speed to the load demand, resulting in better fuel efficiency and longer run times.
Lastly, the power output quality differs significantly. Conventional generators might experience power fluctuations, leading to "dirty" energy that can harm sensitive electronics. Inverter generators provide "clean," stable energy, safe for devices like smartphones and computers.
