An inverter's primary function is to convert the DC power produced by solar panels into AC power that can be used in homes or fed back into the grid. . Before delving into the different output waveforms, it's important to understand the role of a solar panel inverter. Solar panels generate direct current (DC) electricity. Early inverters were rotary motor–generators, connected by a shaft, and they mechanically converted/inverted DC to AC. Square waves can be used to drive some resistive loads, such as resistive heaters and incandescent lamps. But square waves contain many high-frequency harmonic components that cause waveform distortion, cable and motor. . They work by converting the power obtained from the DC source, which is the input source of the inverter, into AC, which is the output source of the inverter, and then distributing it to various devices that require AC sources.
