Solar-Powered Battery System with Backup AC Supply and Arduino Control

Summary

This circuit is designed to create a solar-powered battery system with a backup AC supply, featuring an Arduino UNO for control purposes. The system includes a solar panel connected to a charge controller, which manages the charging of a 12V 200Ah battery. The battery's output is regulated through circuit breakers before being converted to AC by a power inverter. An Automatic Transfer Switch (ATS) is used to switch between solar power and an AC supply as needed. Additionally, the system includes a 5V adapter for powering low-voltage components, such as an IR receiver and a wireless charging module receiver. The Arduino UNO is integrated for monitoring and control, interfacing with the IR receiver for potential remote operation.
