In this paper, a Hybrid solar PV-AC Grid power supply system for 220V, PWM AC, 50Hz, 1kW has been developed. India is facing an acute shortage of electricity, especially in remote areas of rural sectors, due to shrinking conventional grid supply. As a result, the system needs to be integrated with other nonconventional sources like solar energy. The proposed PV system consists of a photovoltaic array, bidirectional PWM converter (THD <5-15%), and intelligent controller. The controller works so that the maximum solar energy stored in Battery is utilized for a particular predetermined load, and the remaining power is drawn from the AC grid. As placed on the rooftop of a house, the PV module does not require extra land or any additional expensive structure. The Green AC power generated through converter from solar panels is given preference over grid power such that the sum of two powers is equal to the required total average load, i.e., 4kWh per day. This has resulted in a grid power saving up to 50% or even more and created a good impact in rural society by generating sustainable (24x7days) power to rural houses for domestic and wage/self-employment among potential youth.
