September 5, 20241 yr Hello i have a question that have been on my mind for a while and i couldn't find much abt it I have seen some people that argue abt the effect of resistive loads or induction cooktops that have a Dimming capabilities some say its not recommended for the inverter and some say it'll affect the sinewave purity and affect other electrical equipment that are running off the inverter has anyone done some tests to see how different load types affect the output using an oscilloscope ?? " images attached are from a video i found that tested the output when using a common dimmer circuit on a resistive load this is the outcome : RIPPLES "
September 6, 20241 yr Those phase chopping dimmers are evil in mu opinion. I'm not surprised they upset many inverters.

To be fair, having seen standard eskom power on an oscilloscope, it is not always a perfect sine wave, depending on what is running in your neighborhood. At uni we had large aircons running and there was quite a bit of distortion on the power line from eskom.
