Abstarct – The process begins with the solar panel, which captures photons to generate DC electricity, which is then regulated by the MPPT (Maximum Power Point Tracking) controller to ensure the Lithium-ion battery bank (configured with three $3.7\text{V}$ cells) charges at peak efficiency. This stored DC energy provides the input voltage for the inverter circuit. The CD4047 IC acts as the heart of the system, configured as an astable multivibrator to produce a stable $50\text{Hz}$ square wave oscillation. These low-power pulses are fed into the gates of two IRF840 MOSFET modules, which act as high-speed switches, rapidly toggling the DC current in a push-pull configuration. This switching action creates an alternating magnetic field within the primary winding of a step-up transformer. The transformer then induces a higher voltage in its secondary winding, stepping the low-voltage DC pulses up to approximately $220\text{V}$ AC. Finally, this high-voltage output is used to drive the LED bulb AC load, completing the conversion from renewable solar energy to usable light.
