Generally, the solar inverters are limited to generate the current harmonics distortion less than 3% but practically, total harmonic distortion at solar incomer comes around less than 8%. Dominant order harmonics are 2nd, 3rd, 5th, 7th and 9th order harmonics. Inverter-based technologies and various non-linear loads are used in power plants which generate harmonics in system. PV inverters use semiconductor devices to transform the DC power into controlled AC power by using Pulse Width Modulation (PWM) switching. PWM switching is the most efficient way to generate AC power, allowing for flexible control of the output magnitude and frequency. But due to many practical factors, these waves might not emerge in an ideal pattern as. Solar PV System comprises of PV modules, charge controllers, solar inverters, battery bank, utility meter and grid system.
