-Inverter generators adjust engine output to meet power demand.  This can mean //at lower power levels// inverter generators can be considerably quieter than older technologies.  At maximum rated power the noise difference between inverter and non-inverter gennies may not be as great.+Standard generators run the engine at a specific speed to output stable power.  Things that affect RMP (load changes, etc) will affect the output.

 +[[https://amzn.to/46oVNLI|Inverter generators]] adjust engine output to meet power demand, and run a more complex/$$ AC->DC-> AC process to ensure steady output at any RPM.

 +As a result //at lower power levels// inverter generators can be considerably quieter and use less fuel than standard generators.  //At maximum rated power// the noise and fuel consumption will be similar.

 +> Inverter chargers generally prefer conventional generator and not inverter generators. This is because they control the amount of power they pull from the generator just adjusting your island frequency. Inverter generators do not handle an external actor trying to adjust the frequency and will rigidly keep 50 or 60Hz until they trip. -- therealrimwarren((https://www.reddit.com/r/SolarDIY/comments/tv41bj/options_for_generator_on_an_off_grid_system/i381dv2/))

 Generators generally have a minimum amount of wattage they can produce.  This means that until you hit that minimum multiple loads can be run for "free", speaking in terms of fuel consumption.  Generators generally have a minimum amount of wattage they can produce.  This means that until you hit that minimum multiple loads can be run for "free", speaking in terms of fuel consumption.
