Solar power generation in India now contributes on a large scale to overcome power deficiency. India's cumulative installed solar capacity is now 63 GW in 2022. The major concern area is the Solar PV generation system implemented on the old existing system. In a PV System Inverter is a major component that performs the conversion process. Due to this conversion, it contributes a large number of odd-order harmonics which effect on power quality of the system. The cost and different types of inverter topology make it more difficult for the consumer to choose. It is being observed that Static Inverter performance is also different for different environment zones. In the paper, the authors simulate stand-alone and grid-connected rotating inverter systems by PSIM software and compare Power output and torque-speed characteristics, Power factor and efficiency, and the Harmonics analysis with static Inverters. After comparison, it is observed that rotating inverters generate permissible odd harmonics as per IEEE 519-2014. Response of the Torque speed characteristics of the Rotating inverter with dynamic load is better than a static inverter.
