A Square Wave Inverter works by rapidly switching DC power on and off to create an alternating current. The process involves the following steps:

1. DC Input Source: The inverter receives DC power from a battery, solar panel, or another DC power source.
2. Oscillator Circuit: An internal oscillator circuit generates a square wave signal by rapidly switching the DC power on and off.
3. Transistor Switching: Transistors or MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are used to alternate the voltage polarity at a specific frequency, typically 50Hz or 60Hz.
4. Output Transformer: Some square wave inverters use a transformer to step up or step down the voltage to match the required output voltage, such as 110V or 230V AC.

Since the output is a pure square wave, it lacks the smooth transition of pure sine wave inverters, making it unsuitable for some electronic devices.
