Multilevel inverters have been extremely applied in industries. A family of optimal pulse width modulation (PWM) methods for multilevel inverters, such as step modulation, can generate output voltage with less harmonic distortion. In grid connected multiple inverter systems, it is normal to synchronize the output voltage of each inverter to the common network voltage. Any controller deficiencies, which result in low order harmonics, are also synchronized to the common network voltage. As a result the harmonics produced by individual converters show a high degree of correlation and tend to be additive. Each controller can be tuned to achieve a different harmonic profile so that harmonic cancellation can take place in the overall system, thus reducing the net t total harmonic distortion level. The simulation results based on MATLAB/Simulink environment shows that the proposed system offers improvement in harmonic elimination and simultaneously inject the maximum power available from PV array into the grid
