2. Electrical System

Understanding the electrical system in your RV is key to a smooth and enjoyable journey, and it's simpler than you might think. Your RV uses two main types of power: 12-volt DC (Direct Current) and 120-volt AC (Alternating Current). The 12V DC is what powers most of your basic RV features, such as the interior lights, fans, and USB charging ports. It's similar to the system in a car and is powered by your RV's batteries. Some RVs also have fridges that run on this 12V DC power, making them efficient for use while driving.

For more powerful appliances, like air conditioners, microwaves, or TVs, your RV uses 120V AC power, which is the same type of power you have in your home. You usually access this power when your RV is plugged into an external power source at a campsite, known as 'shore power' or running the generator. Additionally, your RV might have an inverter, a handy device that converts the 12V DC power from your batteries into 120V AC power, allowing you to use your household appliances even when you’re not plugged into shore power.

Keeping your RV's batteries charged is important. This can be done while driving, as the RV's engine charges the batteries, or through solar panels if you have them. You can also charge them when hooked up to shore power. It’s especially important to take care of your batteries if your RV is going to be stored for a while.

How much power you use each day in your RV can vary. On average, you might use between 50 to 500 amps per day, depending on what appliances and devices you're using. It’s helpful to know that your RV’s battery capacity is measured in amp-hours. This tells you how many amps the battery can provide over a period of an hour. For example, a battery with a 100 amp-hour (Ah) capacity can supply 1 amp for 100 hours, or 10 amps for 10 hours.

In short, managing your RV's electrical system is all about understanding these two types of power and keeping your batteries charged. This ensures that whether you’re parked at a campsite or on the move, you have the power you need for both your basic and high-powered appliances.
