If you are running an RV and searching for what size generator for 50 amp RV, you have come to the right place. In this blog post, I will discuss the different sizes of generators that are available and help you find the perfect one for your needs. We will also talk about the features that you should look for when purchasing an RV generator.

The size of generator you would require for a 50 amp RV,  would be at least a 4000-watt generator. However, I would recommend purchasing a generator that is larger than this so that you have plenty of power for your needs. A 6000-watt or 8000-watt generator would be ideal for a 50 amp RV.

What Size Generator Would I need for a 50-amp RV?

A 50-amp generator can use up to a 12000-watt generator. However, you don’t need to buy such a powerful generator. You should be alright with a 4000-watt unit.

I, however, recommend getting a generator that supplies anything between 6000-8000 watts of power as this would be perfect for all your needs and would not leave you stranded in the middle of nowhere.

How To Choose The Right Generator For A 50-Amp RV

When choosing the perfect generator for your 50-amp RV, there are a few things you should consider.

The number of appliances you will be using

This is one of the most important factors to consider when choosing a generator. If you only need to power a few appliances, then a smaller generator will suffice. However, if you plan on using multiple appliances simultaneously, then you will need a larger generator that can handle the increased load.

The type of appliances in your RV

Different appliances come with different power ratings. For example, an air conditioner will require more power than a television. Therefore, you need to make sure that your generator can handle the appliances you plan on using.

The size of your RV

This is another important factor to consider as it will determine how much power you need. If you have a smaller RV, then a smaller generator will do. However, if you have a larger RV, then you will need a generator that is capable of supplying more power.

The amount of time you plan on using the generator

This is another factor to consider as it will determine how much fuel you need to carry with you. If you only plan on using the generator for a short period of time, then you won’t need as much fuel. However, if you plan on using it for an extended period of time, then you will need to carry more fuel with you.

The brand and model of the generator

Not all generators are created equal. Some brands are known for their quality while others are not. You should do your research and read reviews before purchasing a generator. This will help you make an informed decision and choose a generator that is right for you.

The starting and running wattage of appliances

This is another major consideration that you need to keep in mind when purchasing a generator. The starting wattage is the amount of power that appliances need when they are first switched on. The running wattage is the amount of power that the appliance needs while it is running.

You should make sure that the total starting and running wattage of all your appliances do not exceed the wattage of your generator. If it does, then the generator will not be able to handle the load and you will end up with a lot of blown fuses.

The Best Generator For A 50-amp RV: Factors To Keep In Mind

Before you buy a generator, you need to keep in mind the following factors:

Noise output

You don’t want to buy a generator that is too noisy as it will be a nuisance. Make sure to check the noise output of the generator before purchasing it. Some manufacturers claim their products use “Quiet Technology,” but this isn’t always true. Read reviews to get an idea of how loud the generator actually is.

Fuel type

Most generators run on gasoline, but there are a few that run on propane or diesel. Make sure to choose a generator that runs on the same fuel as your RV. This will make refueling easier and prevent you from having to carry multiple types of fuel with you.


All generators are not created equal in terms of weight. Some are very light and easy to move around, while others are quite heavy. Make sure to choose a generator that is easy to transport so you can move it from your RV to where you need it.

Ease of use

You want a generator that is easy to use so that you don’t have any problems when using it. Check the user manual before purchasing the generator to see how easy it is to set up and operate.


Most generators come with a warranty, but not all of them do. Make sure to check the warranty before purchasing the generator to see what is covered and for how long. This will help you if there are any problems with the generator down the road.

Parallel connection?

This is another factor you may want to consider if you plan on using your generator for a lot of extended power. Some generators allow you to connect two or more units together, which will increase the wattage output. This is a great feature if you need more power than what one unit can provide.

Final Thoughts

A 50-amp RV can use anything between a 3000-watt generator and a 7000-watt generator. It all depends on the size of your RV, how much power you need, and how long you plan on using the generator. Make sure to keep all of these factors in mind when choosing a generator for your 50-amp RV.

However, with a 4000-watt generator, your RV should be powered adequately. I hope this article has been helpful and provides you with the information you need to choose the right generator for your RV needs.
