Solar Power System Circuit Documentation

Summary

This document provides a detailed overview of a solar power system circuit designed to convert solar energy into usable electrical power for charging a 12V battery and supplying power to a 120V AC outlet. The system includes a solar panel, a charge controller, a 12V battery, a power inverter, an Automatic Transfer Switch (ATS), and a 120V outlet. The circuit ensures that the solar panel charges the battery through the charge controller, which regulates the charging process to protect the battery from overcharging. The power inverter converts the DC power from the battery into AC power, which is then routed through the ATS to the 120V outlet for use with standard appliances.
