How to Make MPPT WiFi Solar Charge Controller

Introduction

Solar energy is one of the promising sources of renewable energy. To harvest solar energy efficiently, a solar charge controller is needed. A solar charge controller makes sure that the energy produced by the solar panels is efficiently charged and stored in the batteries. MPPT (Maximum Power Point Tracking) solar charge controllers are the most efficient type of charge controllers as they maximize the energy output of the solar panels. In this article, we will learn how to make a WiFi-enabled MPPT solar charge controller using Arduino Nano.
