When you’re planning your next RV adventure away from campsites you will have to consider bringing a generator that will be capable of running all of your vital appliances. If you have a 50-Amp RV, you will need a powerful portable generator if you want to feel home-like comfort throughout your trip.

In this article, we will delve into all the important considerations when it comes to selecting the perfect generator size for your 50 Amp RV. By understanding the specific electrical requirements of your devices and exploring various factors, we will guide you toward finding the ideal generator to meet your needs and enhance your motorhome camping experience.

So, without further ado, let’s jump straight to important questions and crucial things to consider when choosing a generator size for a 50-Amp RV.

How much power does a 50-Amp RV use?

A 50-Amp RV, equipped with two separate 50A electrical poles, may potentially consume a maximum of 12,000 Watts of power (120V X 100A = 12,000W, where 100A is 50A times 2). That said, it’s important to note that the actual power usage of an RV can vary based on factors such as the RV’s size, installed appliances, and usage patterns.

On average, a typical 36-foot-long Class A RV, after a day’s drive and set up in an RV park, would use around 6,000 Watts of power. This power is distributed between the two legs of the 50-amp electrical system, allowing for a maximum of 50 Amps per leg or 25 amps per leg when both legs are in use simultaneously. This means you will need a generator of at least 6,000 running Watts to run a 50-Amp RV.

Teapots, water heaters, microwaves, coffee machines, TVs, fridges, and dual AC are just a few of the appliances and systems that require power inside an RV. While multiple devices can be running at the same time, it is rare that they will all be operating at full capacity simultaneously. As a result, the power consumption tends to be under 6,000 Watts, ensuring a balanced load between the two legs. Therefore, in practice, a maximum capacity of 12,000W generator will be rarely loaded. Having said that, it will always rely on whether you are using your RV normally or if you are always using a number of high-demanding appliances. This is very individual.

Inside RV appliances wattage total

It’s crucial to understand that a number of the latest RVs are equipped with a feature known as “Load Shedding.” This system monitors the incoming power and reduces the utilization of the available power that falls below the full 50-amp capacity. The Load shedding enables the RV to prioritize power use, ensuring important devices stay functioning while preventing electrical system overload. This capability is especially handy when connecting to a 30-amp shore power source, where available power is limited.

Calculating power requirements for a 50-Amp RV generator

Determining the appropriate generator size for a 50-amp RV involves considering the specific appliances and electronics you intend to power. By assessing your RV’s appliances and their power requirements, you can determine whether your motorhome consumes more or less electricity compared to the average camper.

To begin, create a list of the devices in your RV that you plan to run simultaneously or frequently. For each device, calculate its power usage in Watts and sum up the total. This combined electrical demand will help you determine the necessary power capacity from a generator for your 50-amp RV.

It’s important to note that appliances often require higher starting Watts as they need more power during startup. For instance, air conditioners are typically the most power-hungry appliances in an RV. Approximately 100 Watts are needed for every 1,000 BTUs of cooling power. As an example, a 15,000-BTU AC unit might require around 1,500 Watts per hour during operation and up to 4,000 Watts during startup.

RV AC 15,000 power usage Watts

Other devices such as microwaves, space heaters, water heaters, and coffeemakers can consume anywhere from 600 to 1,500 Watts per hour while running. TVs, laptops, and other smaller electronics typically range from 30 to 200 Watts during operation. Refrigerators would need 150-400 rated Watts, and 700-1,200 startup Watts correspondingly.

It is unlikely that you will use all of these appliances simultaneously. Depending on the circumstances, you might choose to run the AC and a heater together, which could consume around 3,000 Watts per hour and require 6,000 Watts or more during startup. If you plan on running additional major appliances concurrently, you may need a larger generator to meet the power demands.

Recommended generators for 50 Amp RV

Choosing the right generator size for a 50 Amp RV is not an easy task. With so many options available in the market, it can be overwhelming to determine which generator will meet the specific power requirements of your camper. An RV with a 50 Amp electrical system demands a generator that can deliver ample power to run all your appliances and equipment seamlessly.

I put together a list of 5 recommended generator models that have proven to run perfectly with 50 Amp RVs in order to help you in this effort. Each generator on the list below has been carefully selected based on its power output, reliability, affordability, and RV readiness.

How to choose the right size generator for a 50 Amp RV?

Choosing the right size generator for a 50 Amp RV involves considering the power requirements of your RV appliances and systems. To determine the appropriate size, you’ll need to calculate the total power needed, taking into account both the continuous and startup power demands. Here are the steps to guide you:

  1. Identify your RV’s power requirements: Start by identifying the electrical appliances and systems in your RV that will be powered by the generator. Make a list and note their Wattage ratings. This information can typically be found on the appliance labels or in the owner’s manual.
  2. Calculate continuous power demand: Determine the total Wattage of all appliances that will run simultaneously. This represents the continuous power demand. Add up the Wattage values to get the total.
  3. Account for startup power surge: Some appliances, such as air conditioners or refrigerators, require an extra surge of power when they start up. Check the appliance’s documentation or labels for information on their startup surge Wattage. Typically, this value is higher than their continuous power rating. For such appliances use the startup Watts in the previous step’s calculation.
  4. Determine the generator size: Choose a generator with a rated output that is equal to or slightly exceeds the total Wattage calculated in steps 2 and 3. It’s recommended to have a buffer of at least 20% to ensure the generator can handle sudden power spikes without overloading. Look for generators labeled as suitable for 50 Amp RVs or with a Wattage rating higher than your total power requirements.
  5. Consider other factors: In addition to power output, consider factors like fuel efficiency, noise level, portability, and durability. These factors can affect the overall usability and convenience of the generator.

If you want to make your life easier, just pick one of the recommended generators from the previous section of this article. If you’re not using a whole bunch of power-demanding appliances all at the same time, any of the medium-sized (6,000-7,500 Watts) generators will suffice.

Will a 7,500-watt generator run a 50-Amp camper?

A 7500-watt generator should have enough power to run a 50-amp camper. A 50-amp RV typically requires a maximum of 12,000 Watts of power (50 amps x 120 volts = 6,000 Watts per leg, and there are two legs in a 50-amp system, so 6,000 Watts x 2 = 12,000 Watts).

However, it’s important to consider that the power requirements of an RV can vary based on factors such as the size of the RV, installed appliances, and individual power consumption needs. Additionally, starting Watts, which are higher when appliances initially power on, should also be taken into account.

A 7500-watt generator should provide sufficient power for most 50-amp campers, but it’s recommended to assess the specific power requirements of your camper’s appliances and electronics to ensure the generator can handle the combined electrical load, especially during startup. It’s advisable to consult the RV’s manual or contact the manufacturer for precise power usage information and any other considerations specific to your RV.

Will a 9,000-Watt generator run a 50-Amp camper?

Yes, a 9,000-watt generator should be able to run a 50-amp camper. As mentioned earlier, a 50-amp camper typically requires a maximum of 12,000 Watts of power (50 amps x 120 volts = 6,000 Watts per leg, and there are two legs in a 50-amp system, so 6,000 Watts x 2 = 12,000 Watts).

A 9,000-watt generator exceeds the power requirements of a 50-amp camper, providing ample power for running various appliances, electronics, and systems in the RV. It should be able to handle the combined electrical load, including any starting Watts needed during appliance startup.

However, it’s important to consider that actual power usage can vary depending on the specific appliances and electronics in your camper, as well as individual power consumption needs. It’s recommended to consult the RV’s manual or contact the manufacturer for precise power usage information to ensure the generator meets your specific requirements.

Can you plug my 50 amp RV into your house?

In general, it is not recommended to directly plug a 50-amp RV into a standard household outlet in your house. The reason is that most household outlets are not designed to handle the high power demands of a 50-amp RV.

A 50-amp RV requires a specialized electrical hookup, typically referred to as a “shore power” or “RV pedestal” hookup. This hookup provides the necessary 50-amp, 120/240-volt power supply that the RV requires.

Household outlets, on the other hand, are typically 15 or 20 amps and provide 120 volts. Plugging a 50-amp RV into a standard household outlet can cause overheating, overload, and potentially damage the electrical system of your house.

If you need to connect your 50-amp RV to your house for power, it is recommended to have a licensed electrician install a dedicated RV hookup or a suitable electrical connection specifically designed for the power requirements of your RV. This will ensure the safety and proper functioning of both your RV and your home’s electrical system.

Can you run your 50-Amp RV on a 30-Amp generator?

You can plug a 50-amp RV into a 30-amp outlet when using the right type of adapter. A 50-amp female to 30-amp male adapter, which is also referred to as Dog Bones, allows you to use a 30-amp power source.
Keep in mind that the outlet offers less of a maximum current. A 30-amp outlet can handle up to 3,600 Watts of power while 50 amps at 220V (or 240V) of electricity can send up to 12,000 Watts of power.
Pay close attention to the power needs of your appliances. Exceeding the limit of the 30-amp power source could trip the circuit breaker.

Do you need a 50-Amp cord for your generator?

Whether or not you need a 50-Amp extension cord for your generator depends on the specific power requirements of your RV. If your RV is designed for 50-Amp service, then yes, you will need a 50-Amp cord to connect your generator to your RV’s electrical system.

A 50-Amp cord is typically used for RVs that have larger electrical loads and require more power. It consists of a heavy-duty extension cord with a 50-Amp plug on one end and a connector compatible with your RV’s power inlet on the other end. This cord is designed to handle the higher current and power demands of a 50-Amp RV system.

Summary

When determining the appropriate generator size for your 50-Amp RV, it’s crucial to consider the power requirements of your appliances and electronics. Start by creating a comprehensive list of the devices you plan to run simultaneously or frequently in your RV. Calculate the power usage of each device in Watts and sum them up to find the total power demand.

Keep in mind that appliances often require higher starting Watts during startup. Air conditioners, for example, can require up to 4,000 Watts during startup. Other devices such as microwaves, space heaters, water heaters, and coffee makers have varying power consumption, typically ranging from 600 to 1,500 Watts per hour while running. Smaller electronics like TVs and laptops usually range from 30 to 200 Watts. Refrigerators may need around 150-400 rated Watts and 700-1,200 startup Watts.

Based on these calculations, the minimum generator size you would need for a 50-Amp RV is around 6,000 Watts to ensure a comfortable power supply. However, the maximum capacity of a 50-Amp RV is 12,000 Watts. Therefore, a generator with a capacity between 6,000 and 12,000 Watts would be suitable, depending on your specific power demands and the possibility of running multiple major appliances concurrently. By selecting the right generator size, you can ensure a reliable and enjoyable RV experience.

  1. Add up the running wattage of all the devices you intend to power simultaneously, and then add the highest surge wattage from any of those devices. This total will give you the minimum wattage capacity required for your generator.
