It is a type of modified sine wave inverter that uses a multivibrator to generate square wave pulses at a fixed frequency in the output. This helps to convert the DC voltage or signal from the battery into AC voltage. The square waveform consists of only two states, either positive or negative.
They are simpler and offer easy handling, plus they are better at handling power surges. Thus, they are a great option for appliances that are not as susceptible to power fluctuations, like motors. But they may not be suitable for certain loads due to their high harmonic content, which can lead to interference issues.
They offer less safety than sine wave inverters. Square wave inverters produce high levels of noise, resulting in humming sounds in both the inverter and the appliances it powers. However, they are more affordable than sine wave inverters.

What are Modified Square Waves?
Quasi-sine or modified sine waves are alternative names for these particular waveforms. These waveforms are modified square waves that resemble sine waves. Furthermore, the modified sine wave inverters generate peak voltages that closely resemble that of sine wave inverters. These inverters allow you to operate a wide range of devices, although their price is comparable to that of square wave inverters.
