A single phase square wave inverter produces a square-shaped AC output suitable for basic appliances like bulbs, fans, power tools, and older devices. It is not recommended for sensitive electronics but works well for low-cost backup setups. In modern hybrid installations, these inverters may operate alongside Single Phase On-Grid Inverters that handle primary home loads while the square wave unit provides basic emergency power. Their affordability, easy installation, and simple circuitry make them popular in rural homes and small workshops where essential backup power is needed.
