“Modified Sine Waves, as generated by this inverter, produce a much less smooth wave because they kind of pause when crossing zero on the O-scope, and then again at their peak and valley, and those pauses are not as exact or predictable, so they can mess with electronics that are trying to use them as a metronome”
