+ | Things that affect RPM (load changes, etc) will affect the output and can cause "dirty power" (varying frequency). | ||
+ | |||
+ | > You get fluctuation of frequency and voltage as the load changes because the engine cannot respond immediately to the actual load change. There are regulators controlling the engine throttle that attempt to keep the engine at a fixed (design) speed, but it takes time for the engine to respond to new commands as it has to deal with varying fuel/air mixtures and combustion which aren't instantaneous.((https:// | ||

> 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:// | > Inverter chargers generally prefer conventional generator and not inverter generators.
