Solar Charge Controller with MPP Tracking

Basic Principles of a Solar Charge Controller for island or off-grid solar systems. Off-grid solar power systems provide electricity in places without mains power, like clubhouses or garden sheds, using a battery for storage. A charge controller with maximum power point tracking (MPPT) optimizes charging, and this article explains its basics, benefits, and design.
Part 1 has now been published in elektor issue 609 and part 2 in issue 610.
Part 1 deals with the basics, advantages and functionality of an MPP tracker. Part 2 converts the basics into a functioning circuit and explains how it works in detail. Part 3, which will be published shortly, will then cover the software and commissioning.
This project is not only interesting for those who want to build an MPP tracker, but also provides valuable suggestions for the design of power supply units or battery chargers. The software contains many routines that can be used in your own projects, such as a class for controlling the 4-line display that inherits the standard print method.
