Although the 12v system in an RV is not too complicated, there are still few key components to pay attention to. DC current is a type of electricity that moves in one direction only (unlike AC, which alternates directions) and it comes from your 12-volt batteries or the converter.Īn RV’s 12-volt system allows you to use your lights and appliances without needing to be connected to the power grid. The vast majority of gadgets in your RV are powered by a DC power supply and that includes lights, LP leak detectors, fans, 12-volt refrigerators, pumps, slide-out, etc. A depleted battery could also cause a problem if your 12-volt system is not working.
