RV Generators are an essential part of staying safe during natural disasters or other unexpected events. You want to make sure you can power your RV safely and efficiently for the duration of the event. The following article will give you all the tools you need to ensure that your generator will work properly with your RV.

Recommended Power Outputs for RV Generators:

RV generators are meant to be used for emergencies only. They are not meant for everyday use. Because of this, it is recommended that you have a minimum of 4000 watts to power your RV during emergencies. However, if you have a smaller generator, you can still use it if you pair it with an external inverter. All generators with less than 1500 watts need to be paired with an external inverter. We recommend pairing your generator with an external inverter if your generator is less than 1500 watts. 

How to Determine Your Generator’s Power Output:

1) First, you need to know the maximum and minimum watts that your RV can utilize. A professional mechanic or RV shop can help you with this step. If you would like to do it yourself, here is a very simple guide that will help you find out how many watts your generator uses:

2) Next, you need to know how many amps your generator can get. You can get this information by looking at the label on the side of the generator.

3) Now that you have these two items, you can draw a curve with these points and label it “Generator Output.”

4) Next, you need to find the line connecting the two points labeled on your chart. This is what is called a linear formula. The formula is:

P = V * I * 0.8

P = Power (in watts)

V = Volts (this is what you get from the label of the generator on the side of it

I = Amps (this is what you get from the label of the generator on the side of it

5) Now that you have your power output, you can find out what your model needs. Models are listed next to each brand, but some models may need more than others depending on their power needs.

How to Determine Your Generator’s Size:

1) After you have determined how many watts your generator can use, you can figure out what size of generator you need. This number is only based on the number above. Many RV campers don’t know this number because they buy generators that are too powerful for their needs. This will result in overloading the generator and causing it to malfunction.

2) You can figure out your generator’s size by:

a: Using the generator’s label and connecting the dots (line), and labeling them (letters).

b: Measurements will be labeled as 1″, 2″, 3″, 4″, 5″ or 6″. So, you will know how many square feet your generator will cover. The square feet vary greatly depending on generators because it is based on power needs. The square inches for each model vary as well.

How Much Can Power Output Be Hazardous for an RV Generator?

It is not recommended that you try to use your RV generator for more than 6000 watts. This is because overworking the generator will cause it to overheat, which can be very dangerous. You must follow all guidelines listed on the generator before using this product. For example, regulations on some generators state that they cannot be used for more than 4 hours during 24 hours.

If you have a generator with a higher wattage, then it is recommended that you have a 15A circuit breaker in your RV. This will allow you to use the generator more safely without the danger of tripping any voltage.

You can also overwork your generator by not cooling it properly. If the generator is properly cooled, it will work for longer periods without overheating or throwing out an error code.

There are many ways to cool a generator. If you have a portable generator, it is advised that you keep it outside and keep the exhaust fan running over time. This will allow airflow to be directed out of your RV and prevent overheating. However, this method is not effective for larger generators that plug into the wall. These generators need to be connected to an air conditioner or cooling system that cools the air before entering your RV.

Some campers also choose to walk their generators around the RV until it cools down. This is a long process but, you can do it while watching TV from your generator-powered TV.

You can also use a generator power converter as an alternate method of cooling. A generator power converter will cool your generator by sending the heat from the generator to another source, such as a water tank or air conditioning unit.
