Which Is Better Sine Wave Or Square Wave Inverter. While a sine wave has a single frequency in it a square wave contains many higher frequencies as well called harmonics which can cause buzzing or other problems with some equipment. This is because many electrical appliances are designed to run on sine waveform of current only.

During a short time the average output voltage of PWM is shown by the red line which can be seen that the waveform has produced a waveform similar to a sine wave. A sine wave inverter is considered to be much safer for domestic use as compared to a square wave inverter.
In square wave inverter when power goes off the speed of the ceiling fan will increase slightly and make some buzz sound whereas in pure sine wave inverter the speed of the fan remains same and make no noise.
If you are someone who needs an inverter for essential use light up the fan lights bulbs or a few sockets. The sine wave is just the alternating current over time while the square wave is just the same as the current waves in the direct current style. This ensures that the power loss is minimised due to greater efficiency. Pure sine wave output is a far superior cleaner form of output power as compared with modified sine wave or square wave.
