You’re a family of four on the road or maybe a couple or just some friends, and the power’s out. You’re not sure if it’s just your campsite or the whole state. It doesn’t matter because you have to keep going! It’s not easy to get power when you’re on the go. You can’t just park your RV anywhere and plug-in like you would be an outlet at home.

That is where a generator comes in handy! But how does one work? An RV generator converts natural gas, propane, or diesel fuel into electricity to power your home while you are away from an electrical grid. But that doesn’t answer the whole question of how it works, right? Let me tell you the details in the next few lines.

RV electricity basics

First, let me start off by saying that the RV’s generator provides electricity to all of the equipment and appliances in your RV. It also functions as a power source for your generator/charger, used to charge your home batteries. 2,500 and 12,500-watt batteries are just a few of the RV generators available. By turning its combustion engine, the internal combustion engine transforms chemical energy into mechanical electrical power.

The alternator on a motor-mounted engine converts mechanical energy into electrical energy. When electricity is injected into our RV, it goes via the circuit breaker panel, which is fed to the RV’s power and equipment. The homes’ and shore power’s generators are the other electrical sources that operate the appliances.

What is an RV generator?

When I’m talking about RV generators, I usually mean a motor-driven mechanism. An RV generator is a portable generator. In simple terms, an RV generator operates as a backup for your nomad home. You can also use it to power up your refrigerator, lights, and anything else that you need to have running when the power goes out.

These generators are either propane or diesel-powered. Propane-powered generators burn cleaner, but they’re more expensive and must be topped off periodically with fuel. Diesel generators are less expensive than propane, but they’re louder and emit more emissions like nitrogen oxides (NOx) and sulfur dioxide (SO2).

Why do you need an RV generator?

Because in the off chance that your travel involves anything less than a four-star hotel, you will need the power to make coffee in the morning or run your shower at night. In an RV, there is no umbilical cord delivering power from a fixed home site. The generator does its job by pulling fuel and cranking out electricity that provides lights and power through plugs for all of your RV’s electronics.

An RV generator can supply all of the 120-volt plugs in your RV with electricity. The generator also keeps the batteries charged so that when it’s turned off, the 12-volt system continues to operate. Many people will frequently run their RV generator for hours to recharge batteries and operate bigger appliances every day before shutting them down at night if required.

RV generators can be used to power all sorts of appliances, such as air conditioners and microwaves. It’s also possible to charge RV batteries with it. RV generator does not require access to a public electrical grid as a house installation would. Still, if it did have such access, it would be able to deliver twice as much wattage capacity because it has two sets of generators instead of one. That’s why you need an RV generator!

How does an RV generator work?

An RV generator is a power source for recreational vehicles, which usually come with the vehicle. RV generators are specifically designed to provide adventurers with power when disconnected from electricity or public water. You can also purchase one separately that will connect to your RV’s electrical system.

It can power the electronics of the RV with 120V. The generator runs on the same fuels used in your RV’s fuel system. The quantity of energy utilized is determined by the size and amount of work the generator performs. Depending on the RV model and dimensions, the gas tank might hold 50-100 gallons. When there is only half of the oil in the tank, the generator system immediately shuts off.

When your generator is running on gas, electricity, or solar energy, it will automatically turn on to maintain continuous power in the RV. A good step-down transformer is needed to convert the high voltage of the RV’s battery to usable voltage before it enters the house through an outlet or panel.

These generators usually come with an easy-access switch that turns it on and off without entering the vehicle. A large part of keeping up is generating electricity for your lamp posts, appliances such as ovens, microwaves, refrigerators, washers/dryers, and more.

Types of RV generators

Because the batteries were already installed in the RV, most RVs have their own built-in generators that are sufficient for the tasks they’re designed to perform. The downside of a new generator is that it will need additional power. Generators must be examined in terms of their type, which determines the sort of fuel they utilize as well as the size. The quantity of amps required by your appliances is crucial, but so is the generator’s type.

There are three distinct generators for RVs, each with its own set of benefits and drawbacks. Gasoline, diesel, or liquid propane are the three types. If you install a generator in a vehicle that doesn’t already have one, or if you want to make an important upgrade, it’s essential to explore all of your alternatives.


Diesel generates more power and is less volatile than gas. One of the most significant advantages is that considerably fewer refills are needed, and it has the greatest storage and fuel efficiency of all. Diesel engines are often noisier than their competitors, but they lack the pure hum of the other versions.


When not treated, it creates a fire hazard. Petroleum distillates are an ecologically less sustainable option than fossil fuels, and it isn’t the ideal option for those who believe you may damage the environment. Gas can be quickly replenished on your generator, and it may be used to top off your gas tank, making it easier to install into your generator. Gas is probably the least eco-friendly option, but it is an effective way to fill your RV tank.

Liquid propane

Propane is the most difficult to come by and the least potent energy given off when burned. It’s a pleasant decision for your own environment, but you have to prepare when you use it to ensure there are enough resources and ready for the time when you’re not near anything that can buy supplies.

It will be ideal if you keep your green and can store fuel at all times. Fluid propane is the simplest method to maintain, and it is generally safe to utilize as a single product.

Final thoughts

Have you ever been driving your RV and noticed how much gas we’re using to power this thing? It’s time for a generator. As you can see, RV generators are not as complicated as they sound.

A generator is an excellent investment for your RV because it will give you peace of mind and reduce the wear and tear on your vehicle’s battery by providing power when needed. There are many different types of generators to choose from, so make sure you research which one is best for your needs before purchasing.
