How do you know if an inverter is pure sine wave?
To determine if an inverter is pure sine wave, one can employ various methods. Firstly, utilizing an Oscilloscope to examine the wave pattern is a reliable way. If the inverter generates a sine or cosine waveform, it can be classified as pure sine wave, as these waveforms exhibit smooth and continuous variations. Additionally, factors such as price and circuitry can provide indications. Pure sine wave inverters often tend to be relatively more expensive due to the advanced technology and complex circuitry required to produce high-quality, distortion-free power output.
