Just curious - I had always thought the store-bought inverters produced ‘AC’ that was more square wave and less-so smooth sine wave.
referencing your remark “the inverter synthesizes the 60 HZ sine wave on the output”
Be nice if they did produce smooth sine wave. I don’t know; what say you?

Indeed, that used to be true. Technology marches on; newer inverter technology produces quite clean sine wave power.
That said, I’m sure you can still find cheap crappy square-wave inverters from *some* Chinese vendor. :-)

Modern inverters do produce a sine wave. You just need more mosfets on the output.
Older inverters used power transistors and we didn’t have the digital circuitry to do the syntheses anyway.
