The waveform may approach a pure sine wave when under no load or while powering a resistive load like a heater, but connect this inverter to an inductive load like a microwave oven, a portable AC unit or other motorized inductive load and I'll bet your scope will display a pretty distorted waveform. These cheap, high frequency, transformerless inverters offer a weak surge capacity as well as a short life expectancy, especially when powering inductive loads. Low frequency, transformer based inverters on the other hand offer a much higher surge capacity for starting and running inductive loads and they last far, far longer than these lightweight high frequency inverters.
I'm glad you spoke about grounding. I purchased this because I didn't have the ground. I just wish it came with a remote control.
Ah! A remote! I cam across one that has a remote but no ground lol.

You have a point. I'll add a microwave test the next time I do an inverter.
Would brand of inverter would you recommend then?
@@MikeC-mf7dv Schneider Electric, Outback Power, Sigineer Power, Victron Energy, or Magnum Energy.
