Present paper proposes a simpler synchronized series RC phase angle control based push pull inverter topology using parallel combination of Power MOSFETS and a step up center-tap transformer to convert DC power available through solar panels, supported by battery backup to AC grid. A single phase quasi square wave three level inverter is employed to convert Solar DC solar power to a quasi square AC voltage, using a step-up centre tap transformer. The output voltage and phase angle of the inverter connected to the AC bus is kept controllable by duty ratio control and phase angle cantor respectively. A proposed prototype inverter model tested to verify power fed to 230 Volts AC supply.
