Solar Power System Circuit Documentation

Summary

This document provides a detailed overview of a solar power system circuit designed to harness solar energy through a solar panel, manage power flow via a charge controller, store energy in batteries, convert DC to AC power using an inverter, and distribute the power through multiple 120V outlets. The system includes safety features such as a circuit breaker to protect against overcurrent conditions.
