Efficient Energy Management System for DC Micro Grid Including Electric Vehicle Charging Station

Using a microcontroller idea, the project's plan automatically chooses supplies from the mains, generator, inverter, and solar. Since providing all four supply sources is impractical, one source is outfitted with extra switches to achieve the same objective. We regard the four switches in this project to be four distinct supply sources. Any switch we press indicates that the specific source that supplies the microcontroller with input signals is not present. Microcontrollers from the 8051 series are used here. The ULN2803 functions as a relay and receives the output from the microcontroller. In this instance, 12V relays are used.
