How to Make MPPT Solar Charge Controller DIY

Introduction

With the increasing demand for green and sustainable energy sources, solar power has become a popular option for powering homes and other appliances. Solar panels, however, often require solar charge controllers to regulate and manage the charge they receive from the sun. Maximum Power Point Tracking (MPPT) solar charge controllers are efficient and effective in ensuring that the solar panel is receiving the maximum amount of charge that it can handle. In this article, we will show you how to make a MPPT solar charge controller DIY using an Arduino Nano.

In this video, I am going to make MPPT Charge Solar Controller. This MPPT charge controller can work for 12v amd 24v batteries. Its input supply can be 15v to 80v. This charge controller can be used with different types of batteries. This is a improved version of previous charge controller posted earlier.
