FAQ

What are the differences between pure sine wave and modified sine wave?

The primary differences between pure sine wave and modified sine wave inverters lie in the quality and characteristics of the output voltage they produce.

Pure Sine Wave Inverter: The output of a pure sine wave inverter is comparable to or better than the electricity provided by the grid. It is characterized by a smooth and continuous wave that rises and falls evenly. Different manufacturers may use terms like "true sine wave inverters" to describe pure sine wave inverters, but they all refer to the same high-quality output. As illustrated in the figure below, the 120VAC pure sine wave voltage increases and decreases smoothly. When the voltage passes through 0V, the polarity changes instantly and smoothly, ensuring a stable and clean power supply. Pure sine wave inverters are ideal for sensitive electronic equipment, such as computers, medical devices, and audio/video equipment, which require a stable and precise power source to operate correctly.

Form of pure sine wave

Modified Sine Wave Inverter: The voltage from a modified sine wave inverter rises and falls sharply, producing a waveform that resembles a staircase rather than a smooth curve. The phase angle of the modified sine wave is not smooth and changes suddenly. Additionally, the waveform holds briefly at 0V before changing polarity, which can lead to loss of efficient power delivery and potential issues with certain electronic devices. Standard voltmeters cannot provide an accurate reading of a modified sine wave. To measure the voltage accurately, a "True RMS" (Root Mean Square) meter is required. Modified sine wave inverters are generally suitable for less sensitive equipment and appliances, such as power tools, small motors, and non-sensitive lighting. However, they may cause issues with devices that rely on precise power input.
