What is a modified square wave inverter?

A modified square wave inverter is a type of power inverter that converts direct current (DC) into an alternating current (AC) output that approximates a square wave. Unlike pure sine wave inverters, which produce a smooth and continuous waveform, modified square wave inverters create a stepped waveform that can have higher harmonic distortion. This makes them more suitable for simpler devices and applications, such as small appliances and lights, but may not be ideal for sensitive electronics that require a cleaner power supply. They are generally less expensive and easier to manufacture than pure sine wave inverters.
