Many people default to 12V, but is it really the best option? In this video, I’ll break down the differences between 12V and 24V, showing you where 12V falls short, how 24V can save you money, and when you might actually want to stick with 12V instead. We'll cover: - Cable size and cost – Why 12V requires thicker, more expensive wires - Charge controller savings – How 24V cuts your controller costs in half - Battery charger efficiency – Why 24V makes charging cheaper and easier - Power loss in low-voltage systems – How much energy you're wasting at 12V - The downsides of 24V – When 12V might still be the better choice If you have more than 400W of solar or an inverter larger than 2000W, a 24V system is often the better choice. But if you need to charge from an alternator, you may still want to stick with 12V.
