Finding the right generator for your RV is not an easy task. There are many different types of generators with different power outputs. The most important thing to consider is how much wattage you need. If you have a larger RV, then you will need at least 50 amps of power to run everything in it without any problems.
A small generator can be enough if all you are using it for is running lights and fans inside the camper while camping or tailgating at a football game on a sunny day, but that won’t work for larger RVs which require more electrical power to operate appliances like refrigerators, microwaves, TVs and sinks.
This article will help you determine what size generator to buy for your 50 AMP RV and give you some tips on how to choose the right one.

How to Choose the Right Size Generator for 50 Amp RV?
Determining Your Electrical Needs
RVs come in all sizes, shapes, and weights. The size of the generator you need is determined by how much electricity your RV uses while powering appliances at one time.
Generators are measured in watts or Kilowatts (KW) to determine their power output compared to other models on the market. You can use a handy calculator online that will help you get an idea of what wattage generator would work best for your 50 amp electrical line coming into your camper’s box/breaker panel from the shoreline connection port. When calculating this number keep in mind any additional items like TV or lights that may be used simultaneously with kitchen appliances when cooking dinner inside the RV unit during evening hours after sunset until bedtime.
Generators come in different shapes and sizes with differing power outputs depending upon their wattage output numbers. A larger fuel tank or gasoline engine size will allow longer periods of running without refueling as well. Diesel engines typically last longer between maintenance intervals than gas-powered models that need oil changes more frequently because they operate hotter due to higher compression ratios – around 35-40 PSI compared to 20 PSIs for standard car motor combustion chambers.
However, diesel has been known historically to be much slower starting in cold weather after winter versus its equivalent gallon amount of unleaded gasoline.
Solar panels tied into battery banks make good sense for off-grid usage of smaller RV units not meant to travel more than perhaps 50 miles between refueling stops.
Wattage
A 50 AMP RV uses a generator that puts out at least 12,000 watts. Because of this, it is extremely important to calculate the wattage of appliances and pumps before choosing the right sized generator for your rig.
If you only plan on using your RV for weekend getaway trips and will not be powering appliances simultaneously, a smaller wattage generator may suffice such as 4000-5000 watts or lower output models with larger capacity fuel tanks.
They can run up to 20 hours between refueling when used at 25-75% of its rated power – this is dependent upon the load demand placed by what’s being powered in addition to that single appliance drawing current from the unit right now.
It is recommended to have a minimum of 125 watts for every hour you plan to run your appliances so if you are planning on powering them all at once, be sure to find the right generator accordingly.
For example: powering one 120 volt RV air conditioner and utilizing 1000 watts draws more than twice as much power compared to 500 watts which use half the electricity since motors like these AC units draw large amounts of energy continuously until they are turned off.
Portability and Size
While larger models may be more powerful, they tend not to be as portable because their weight increases exponentially compared to smaller models (and gas tank capacity). If portability is critical then it’s recommended that you purchase one designed specifically for an RV or camping application.
It’s a good idea to keep your generator small and lightweight. That way, it is portable enough for you to take along with the rest of your camping equipment. You don’t want something that weighs hundreds of pounds or is so large that there isn’t room in your vehicle when you’re driving out into nature.
If you’re going on a long trip in which you’ll be spending multiple days in nature without access to electricity, then having something too large or heavy will just add more work when setting up camp each day. You’ll want a lighter load so that carrying it around isn’t such a chore.
Fuel Efficiency
RV generators are designed to be fuel-efficient, so it’s important to buy one that meets the needs of your RV. Otherwise, you will spend more money on gasoline than necessary.
In general, smaller generators are more fuel-efficient than larger ones. However, experts recommend you buy a generator that is slightly larger than the minimum size needed to power your appliances and any other equipment in use at once.
This will prevent “brownout” situations where you risk having trouble using certain appliances because they receive low voltage and can stop working (this happens when there isn’t enough power for everything; however, if you have too much it wastes gas).
One important thing to remember with generators is that they are most efficient when run at no more than 80% of their maximum capacity, so it is best not to hook up too many appliances together or you will be losing out on fuel efficiency.
Quiet Operation and Noise Level
The quiet operation of an RV generator makes it perfect for enjoying all types of outdoor activities without having to worry about disturbing everyone around you with loud noises or smells coming from your machine. An RV generator that is only as loud as a lawnmower will be able to operate without disturbing your camping neighbors.
The noise level of the generator directly correlates to how much electricity it will produce. If you need a large amount of energy, then more fuel will be consumed and create more heat, which in turn creates even more sound from the engine. If you are looking for something that is quiet or silent while camping, then choose a smaller electrical output unit rather than one that is industrial grade with higher wattage outputs.
Generator Weight
Generators can be heavy, so choose one that is light enough for you to carry. If it has wheels, the weight will increase dramatically. Smaller generators are lighter than larger ones and may not require two people to move them around easily.
The smallest models, such as those made by Generac, start at about 18 pounds up to 150-300 pounds for larger ones with stronger electrical output.
A medium-sized 100/125-pounds unit is capable of powering a whole RV if it has enough fuel or batteries depending on its wattage rating.
You should calculate your electric needs based upon certain factors: average watts per hour used by each appliance; total hours that an appliance runs in one day; the number of days you plan to stay at your camping site, etc.
Parallel Connection
Parallel connection of two or more generators is the most common way to increase available power. To use this method, all of your generators must be able to accept 240 volts (if you’re using 120/240-volt appliances). The total amperage output will not exceed that of its smallest unit.
There are 3 options for connecting multiple units:
- Series connection. A series connection for multiple generators is an option when you need a more powerful source than what your smallest generator can offer. The output of the entire system will be that of its smallest unit. To use this method, all units must have identical voltage input ratings and electrical configurations (AC or DC);
- Parallel connection. Like Series, Parallel connection is an option that allows for higher total capacity than your smallest unit can provide through the addition of more generators to increase power output. The key difference between these two options is that all units must be able to accept voltage input ratings and electrical configurations (AC or DC) but not all have to match identically like in series! This means you could connect three 3000 watt AC/DC models together;
- Series/Parallel connection. The Series/Parallel connection is a combination of the two aforementioned ways to connect generators together for more power output than what your smallest unit can provide. It’s commonly used when redundancy and maximum capacity are both keys, such as in medical facilities where downtime must be avoided at all costs or data centers that require large amounts of processing power 24/365;
Fuel Type – Gasoline vs. Diesel
Gas generators are generally cheaper than diesel, but the initial purchase price doesn’t tell you everything. You should also consider how much fuel costs and whether it will be available to buy in your area when you need it. If gas stations aren’t common for miles around where you camp, a gasoline generator might not be the best choice for an RV at 50 amps because of its dependency on readily available fuel.
If you are in an area with easy access to fuel, then gasoline can be a great choice. Gas generators are generally cheaper than diesel, but the initial purchase price doesn’t tell you everything. You should also consider how much gas costs and whether it will be available to buy in your area when you need it.
Diesel generators cost more initially. However, they use less expensive fuel (diesel) which lasts longer and is safer for storage over time because of its stability at room temperature compared to propane or gasoline.
Some research suggests that operating on diesel may end up costing about $0.50/hour less than using gasoline once all factors – price per gallon, hours on generator per day, and the number of gallons used – are taken into account. Diesel is the more popular choice for these reasons.
Is Your Generator RV-Friendly?
The first thing to consider when buying a generator is whether it can be used with your RV. Generators are available in 3 types: gas, propane, and diesel generators. While all generators may power appliances that run on DC current (like microwaves), only the latter two will provide AC voltage for powering electrical devices like TVs or stoves directly.
Gas-powered units can still work by converting their output to 12V DC through an inverter, but this process reduces its overall efficiency, and running them long-term could damage equipment plugged into it due to fluctuations in the current they produce. There’s also no guarantee that you won’t blow out your converter or breaker because of these issues either.
Budget
The generator budget is an important consideration when you’re buying a new generator. You don’t want to pay too much, but it’s also important not to buy the cheapest one available either.
The average price for a new 50-amp RV generator is between $700 and $900 dollars. A more expensive unit may have additional features that you’ll probably never use but will pay off in terms of convenience if you do need them someday.
FAQ
How many watts does a 50-Amp RV use?
An average 50-AMP RV uses about 12,000 watts. Even if you use an adaptor, your 30-amp service RV won’t receive more power than the 3,600 watts it can handle. If you utilize a 50-amp RV adaptor, on the other hand, you’ll be restricted to 3,600 watts.
Some appliances will use more than others will, so this is just an estimate of the average amount needed to run everything within your vehicle simultaneously.
How to estimate your generator size for your RV?
Determine the total wattage of all appliances that will be on at once. If you have a microwave, coffee maker, and toaster oven, add them together for an approximation of your starting load in watts. Add 30% to this number. This is the size generator needed so as not to overload any circuits or trip breakers when powering these appliances simultaneously while running other devices such as water pumps and air conditioner compressors at different times throughout use of the RV.

What is the difference between 30-amp service and 50-amp service?
The 30-amp service is usually used for small RVs, popups, and small or mid-sized motor homes.
The 50-amp RV circuit has the same wire gauge as a dryer outlet in your home (the #12 AWG).
One big difference between the two sizes of power outlets is that you can’t plug an extension cord into it to increase its length.
Can you plug your 50-amp RV into a 30-amp?
Yes, but you will need a 50 amp to 30 amp adapter.
Will a 9000-watt generator run a 50 amp RV?
Generators are rated in wattage, and the larger the number is, the more power it has: a 50-amp RV might require as much as 12,000 watts. A 9000-watt generator would be able to run your 50 amp RV without issue.
Is a 50-Amp RV plug 110 or 220?
A 50-amp RV plug is 220 volts. If you have a generator that does not put out enough power to run the appliances in your RV, or if it’s too loud for comfort, consider investing in another one designed for recreational vehicles.
Is 30 amps enough for an RV?
No, it is not enough for an RV. A 30-amp power supply will only produce up to 2,400 watts on a continuous basis or 4,800-watt surge capacity. In comparison, a 50-amp service can provide between 36 and 64 amps of energy depending upon the size and type of appliance that has been plugged into it. This is because RVs require high amperage appliances in order to run efficiently (e.g., air conditioner).
Will a 7500 watt generator run a 50 amp RV?
The answer is yes, a 7500 watt generator can run a 50 amp RV. However, you will likely need to use two plugs and split the load between them in order to ensure that your appliances are not overloaded. Additionally, if you plan on running several large appliances at once or have very high electrical demands such as an air conditioner or electric heater, you may want to consider getting a higher wattage generator for greater power output. Make sure to check the total wattage rating of all the items you plan on running with your generator before purchasing one so that you get the right size for your needs.
Will a 8000 watt generator run 50 amp RV?
It depends on the type of generator. Generally speaking, an 8,000 watt generator won’t be powerful enough to run a 50 amp RV. A 10,000 watt generator is usually recommended for this purpose, as it will provide plenty of power to keep your appliances running without straining the generator’s capacity. However, if you’re looking for something more cost-effective and don’t plan to use all of the available appliances in your RV at once, then an 8,000 watt generator may be suitable for your needs. Be sure to do some research and read reviews before making any final decisions about which size of generator is best for you.
Will a Predator 3500 run a 50 amp camper?
The Predator 3500 generator is an inverter type generator, meaning it’s not specifically designed to run 50 amp RV appliances. However, if the electrical requirements of your camper are less than 3,500 watts, then it can likely power your appliance without a problem. To be sure you’re getting enough power for your needs, you should double check the wattage requirements of each item you intend to plug into your camper before using the Predator 3500 with it. If all items combined require more than 3,500 watts at any given time, it may be best to look for a larger-capacity generator instead.
Are there any specific generators that are made for RVs?
Yes, there are several generators specifically designed for RVs. They usually range from 5 KW up to 7 KW in power and are designed to be able to handle 50 AMP RV applications. Many of these generators run on gasoline or propane and produce clean, reliable power that is ideal for recreational vehicles. Some RV-specific generators also feature an electric start option which makes them easier to use than standard portable generators. It’s important to note, however, that these RV-specific models may cost more than standard portable generator options.
Can you run two air conditioners on a 50 amp RV?
It depends on the energy requirements of your air conditioner. Most RV air conditioners are rated in BTU’s, which stands for British Thermal Unit and measures how much cooling power an air conditioner can provide. A 50 amp RV outlet can provide up to 12,500 watts of power, so if your two air conditioners only draw 7,500 watts total then you should be able to run them off a 50 amp RV outlet without any issues. You may want to check with the manufacturer to make sure that is enough power for both units. If it isn’t, then you will need a larger generator to power them both simultaneously.
How do you know what size generator to get for your RV?
When it comes to generators for your RV, size matters. You’ll want to make sure you get the right size generator for your needs. Here are a few tips on how to determine the right size generator for 50 amp RV:
- Know what your power requirements are: Start by understanding exactly how much power you need and what types of appliances you will be running off the generator. This will help you figure out the wattage required and, in turn, help determine which size of generator is right for you.
- Consider portability: If portability is important to you, then consider a smaller generator that won’t take up too much space when not in use or while traveling with your RV.
- Consider the type of fuel: Depending on your preference and availability, you may want to consider diesel or gasoline generators for your 50 amp RV. Both have their advantages and disadvantages so it will be important to do your research to see which one is best suited for you.
Are there any special features that come with a 50 amp generator?
Yes, many 50 amp generators come with features that make them an ideal choice for RV owners. These can include a remote start and stop feature, as well as adjustable voltage control to ensure your appliances are always running optimally. Some models may also have additional outlets for charging devices or powering other electrical items, making them perfect for camping trips or lengthy stays at the campsite. Many models also come equipped with overload protection to prevent damage to the generator in case of power surges. Additionally, some 50 amp generators offer fuel shutoff sensors to automatically shut down the system should it sense low oil levels in the tank.
Is there a difference between generators for RVs and generators for homes?
Yes, there is a difference between the generators available for RVs and those for homes. RV generators are designed to be lightweight and small – they don’t typically produce as much power as home generators. So when selecting a generator for an RV, you should look for one with a lower power output than what you would use in a residential application.
For example, if you’re looking for a generator that can safely power your 50 amp RV, then you should choose one with at least 7500 watts of peak power. This will ensure it has enough capacity to provide sufficient current without overloading the system and risking damage to your electrical systems or appliances. It may even be beneficial to opt for a higher wattage model so that you can power multiple appliances or devices without having to worry about overloading your RV’s electrical system.
How many amps will a 3500 watt generator produce?
Most 3500 watt generators will produce an average of 29 amps at 120 volts and 58 amps at 240 volts. This is generally enough power to run most of the appliances in a 50 AMP RV, including air conditioners, microwaves, and washing machines. However, it may not be sufficient if you intend to run multiple high-demand appliances simultaneously. You may need to consider a larger generator with more amperage output such as a 4000 watt or 5000 watt option.
How many amps does a 7500 watt generator produce?
A 7500 watt generator will typically produce around 62.5 amps at 120 volts. This means that it would be more than enough to power a 50 amp RV, as the average 50 amp RV requires only 30 amps at 120 volts. However, if you are looking to use other appliances or electronics along with your RV, then you may want to look into getting a larger generator that can provide more power. It’s also important to consider what type of fuel source your generator uses and how much space is available in your setup for the generator itself.
How many amps does a 6500 watt generator produce?
A 6500 watt generator produces a maximum continuous output of 54.2 amps. This is enough to power multiple appliances and electronic devices simultaneously, making it ideal for RVs with 50 amp requirements. However, you should always check the electrical requirements of your RV before purchasing a generator as your RV may require more than 50 amps. Additionally, make sure to look into wattage ratings as some 6500 watt generators may only provide 5000 watts or less depending on their design and features. It is important to select a generator that meets all of the electricity needs of your RV in order to ensure safe and reliable operation.
