In this video, I tackle everything you need to know about how to size a charge controller, ensuring your solar system operates at peak efficiency. With over 2000 positive reviews, my book has powered up countless off-grid adventures, and now, I'm bringing that expertise directly to you.

Starting with the basics, we'll explore how to figure out what size charge controller you need, breaking down the calculations in an easy-to-understand format. Whether you're dealing with a single 12V battery and 200 watts of solar or scaling up to a more complex system, I've got you covered. From understanding the importance of series vs. parallel wiring to diving into the specifics of solar charge controller sizing, this video is packed with invaluable insights.

We'll also dive into real-world applications, demonstrating how these principles apply to actual setups like a cabin powered by solar. Plus, I'll share tips on optimizing your system for both safety and efficiency, including the critical considerations for fuse and wire sizing. And, for those curious about maximizing their system's potential, we'll discuss the maximum input voltage your charge controller can handle and the impact of your wiring choices.

This video is not just about theory; it's about practical, actionable advice. Whether you're wondering 'what size charge controller do I need?' or looking to refine your existing solar setup, you'll find answers here. And I'm eager to hear from you too – leave a comment with your setup or any questions. Your insights make our solar community better.
