Are you ready to head out on your next RV camping adventure? Before you go, it’s important to have a basic understanding of your RV’s electrical system. Many of the conveniences you find in your RV—everything from the lights, refrigerator and furnace to your slide out rooms—require electricity.
Your RVs electrical system is a combination of 12-volt DC (direct current) and 120-volt AC (alternating current).
The 12-volt system is powered in three different ways—a battery, a converter, and your tow vehicle’s system. The battery is actually the heart of your 12-volt system, storing the electrical energy from your converter or tow vehicle until you need it.
The 120-volt system is powered by plugging the shoreline cord into an outside power source or running a generator, if equipped. Once connected you can operate the roof air conditioner, microwave and use 120-volt receptacles throughout the camper. Even while you are plugged into shore power, your 12-volt systems continue to operate off your battery. However, when plugged into shore power, the converter in your electrical power center panel automatically charges your battery.
To better understand your RV’s electrical system and to avoid overloading the system, we recommend you review your RV Owner’s Manual and watch the video below.
