Cables are simple right? They just join two things together, Simple as that. Well yes and no, it’s important to size your cable correctly for the job. You can put a small cheap cable in and you will lose lots of power in the cable or start a fire if it's not fused. Or just blow the budget and whack the biggest cable in. We like to get the balance right. Use a cable calculator like this cable calculator. For solar panels enter the voltage, the solar panel current and the distance to controller, aim for 3 percent voltage drop. Same with running appliances enter the voltage of the appliances, the cable length and the current. Or just buy a kitset where we have already done the calculations for you.
