In the video above, I break down how to size your off-grid system properly — including how much solar you actually need, what inverter size suits your lifestyle, how to charge from your alternator, and the battery bank that makes it all work reliably. If you're unsure where to start or want to future-proof your setup, this will help you get it right from the beginning.
