Abstract
 

This project is designed to automatically supply continuous power to a load through one of the four sources of supply that are: solar, mains, thermal, and wind when any one of them is unavailable. The four switches represent the four causes. The switches are connected to an 8051 microcontroller of which they provide input signals. Whenever a switch is pressed, it shows the absence of that particular reference. A relay driver is used that receives microcontroller generated output and switches that specific relay to provide continuous power supply. A lamp or bulb is used as a load for demonstration purpose which draws power from main. When the primary fails to supply power, automatically next available source is used like thermal. If thermal fails then the next one is used and so on. An LCD is used to show which power supply is on.
