Tips：Pure Sine Wave VS Modified Sine Wave

The pure sine wave output is equal to or better than our grid power. Different inverter manufacturers may use different terms, which mean the same thing, like true or full sine waves. As you can see in the figure below, 120VAC pure sine wave voltage rises evenly at the smooth phase angle and decreases evenly at the smooth angle. When it passes through 0V, its polarity also changes immediately.

Form of pure sine wave

With the modified sine wave, the voltage rises and falls sharply. The angle of the phase is not smooth and can change suddenly, causing the waveform to look much like a staircase. The modified sine wave also briefly stays at 0V before changing polarity. You cannot get an accurate voltage reading with a standard voltmeter, you must use a "True RMS" meter to read the modified sine wave.
