Because of the increasing and escalating demand on energy sources, utilizing renewable energy sources efficiently becomes mandatory. This paper aims to construct and discuss efficient and low-cost configuration of standalone PV water pumping system with three-phase induction motor. This configuration is achieved by using optimized PI-controllers with the Jellyfish optimizer and a high gain DC to DC converter with maximum power point tracking technique to extract maximum power from the PV system. In addition to the high gain DC to DC converter, the proposed system consists of PV array, DC to DC bidirectional converter with batteries in order to save excess PV power and reuse it when there is no enough output power for the system, three-phase inverter, three-phase induction motor, and pump to drive the water. The proposed system succeeded to keep the total harmonic distortion for the AC output voltage within 0.61%, and keep DC bus voltage ripple factor within 0.2%, both are within acceptable limits. The system is designed, modeled, and simulated in detail using MATLAB/Simulink software to evaluate the performance under fast variations of climatic profile.
