Abstract The   term   solar   smart   inverter   has   become   a buzzword in the electronics industry which is a blending of multilevel inverter, solar tracking and solar charging.  Inverters are predominantly classified as single level inverters and multilevel inverters.  Minimum harmonic distortion, reduced EMI/RFI generation   are the major   advantages of multilevel inverters as compared to single level inverters.  Multilevel inverters can operate on various voltage levels. Multipurpose applications, such as active power filters, machine drives for sinusoidal and trapezoidal current applications can be realized by multi-stage inverter.  By incorporating pulse-width modulation (PWM) control,   within   the   inverters we can   control   the   gain   of inverters more effectively. One of the most forthright methods of describing  voltage sou rce modulation for multilevel inverter is carrier based  PWM  schemes  that  can  be conceived by the intersection   of  a  modulating  signal  with  triangular carrier waveforms.  In this paper,  we are  designing  a Solar  Multilevel Pulse  Width   Modulator  inverter   using  microcontroller and cascade  H bridge  topology which increases  the efficiency and reliability of the  system.  We are also assimilating Maximum Power Point Tracking for higher efficiency. The solar panel will track the sun from dusk to dawn to get maximum power.

Keywords Multilevel inverter; pulse-width modulation; H-brige; Stepper Motor; ATmega328 microcontroller
