This research paper aims to support the 9-level Cascaded hybrid bride based Multilevel configuration that is connected to a photovoltaic system. The term multi-level implies that an n-level inverter is capable of manufacturing an-voltage level instead of producing 2 levels as within the convention two-level inverter. the multilevel electrical converter configurations may draw an input current with low distortion, operate at the upper switch frequency and lower switch frequency with lower switch loss and achieving higher potency and ensuing lower total harmonic distortion within the output wave while not victimization any filter circuit. This is the main concept implies in the multilevel inverter by using several semiconductors switches to produces several voltage levels. The symmetric configuration is introduced to scale back the amount of a full of active switching component that is cost-efficient. The concept of Grid-connected PV system is highly popular and preferable for both medium and high power demands. The Simulation strategies of voltage responses and THD responses for asymmetric and symmetric photovoltaic array associated with the 3 phase 9-level CMLI(cascaded Multilevel Inverters) are being carried under the MATLAB environment.
