Many appliances and devices require 120V AC power. When your RV is plugged into shore power, you're bringing a source of 120V AC electricity into your RV to power those appliances and devices, just as if you were at home. But the battery/batteries in your RV provide 12V DC power. So, when the source of your. DC (direct current) is constant, while AC (alternating current) cycles up and down from +120V to -120V and back. A power invertertakes 12V direct current and converts it to 120V alternating current by first increasing the voltage and then modifying it so that it. There are two different types of RV inverters – pure sine wave and modified sine wave. The main differences between them are efficiency. You'll likely have one of a few different types of inverters, but no matter what type you have, the inverter is unlikely to supply power to everything on board the RV. What it does power. A lot of people don't understand the difference between an INverter and a CONverter. The simplest explanation is that they are the direct opposite of one another. They each change the properties of electricity that passes through them. but in exactly.
