How to Choose the Best RV Generator – Buyers Guide
- Generator Considerations
- Electrical Output
- Fuel Type
- Noise Level
When selecting a generator for your recreational vehicle or trailer, consider your power needs and the required power output.
Will you be powering appliances and devices directly and rely mainly on the generator? or will you use it primarily to charge batteries, or as a backup solution in case your solar installation can’t deliver enough power?
Try to gauge if you’ll be adding equipment in the future and don’t choose a model with too little power.
Considerations for a Portable RV Generator
Several factors determine which kind of generator and exact model you should get. It needs to be powerful enough to provide sufficient output for everything you want to run.
The available outlets should allow you to connect all your hardware such as charge controller, appliances and devices.
You might also think about what noise level you can tolerate and how long the generator should run, how portable it should be and what extras you require. We’ll go into more specifics after our top selection.
The appliances, devices and gadgets you intend to run, charge or use at the same time determine your power needs.
For a small and frugal camping trip, a generator with 1000W to 2000W power might be sufficient, as you’ll only run lights or an electric cooker at a time and maybe charge batteries or electronics at night.
RV generators commonly use three different fuel types: gasoline, diesel, propane, and natural gas.
It comes down to preference and what is available to you, but keep in mind that most people prefer a gas-powered generator if their vehicle runs on gas as well since they only need to fuel up on one type.
A budget-friendly choice that is convenient for vehicles running on gas as well. Gas is readily available and gasoline generators are affordable and economical.
These are fuel-efficient models and a good choice for a diesel motorhome. A diesel generator typically can deliver more power, yet emits more noise. It is not common choice.
With propane, you don’t need to worry about fuel going bad as it has an indefinite shelf life. Propane generators are quiet with little emissions, yet their limitation is their tank size and you can’t refuel them everywhere.
This is the number of hours your generator is able to provide power on a full tank of fuel.
When relying on power throughout the night, you don’t want to have to refuel in the middle or early morning, so a solid eight hours is a good value to aim for in that case. All of the models we’ve reviewed feature an inverter.
Noise is an issue for generators and many people prefer a quiet model. Unfortunately, this usually means a smaller, less powerful generator.
Thanks to mufflers and improved technology, engines have becoming quieter. Generators are rated in dBA for noise output, which is a standard measurement and lists the noise emission in decibels from a certain distance (23 feet).
To give you an idea: a person breathing is rated 10 dBA, whereas a regular conversation ranges around 50 dBA. Keep in mind that noise is not only an issue for you but those around you as well.
While placing a generator far away from your vehicle certainly makes it quiet enough so you can enjoy your TV, your campground neighbors will think differently.
EPA certification and CARB compliance is not just for the environmentally-minded RVers.
Short for California Air Resources Board, an environmental protection agency specialized in air pollution. They can issue emission standards under the federal Clean Air Act.
Emission restrictions might not only apply in California, but in national parks and nature protected areas as well.
Although all RV generators we reviewed are categorized as portable, some are certainly heavier and bulkier. The decision comes down to how much space you have available for stowing a generator and how much extra weight you can take on.
As mentioned, all generators on our list feature an inverter, making them fuel-efficient and reducing total harmonic distortion so sensitive electronics are protected from power surges.
Other extras you might want for your RV generator are an electric starter, which is particularly useful in cold weather where a recoil starter might frustrate you.
A fuel gauge is great if you find it hard to estimate how long a tank will last, while a service meter tells you when the next check-up or maintenance is due. A low oil sensor protects the engine
How to Take Maintain and Care for Your Generator
Start and run your generator monthly – Like any other mechanical equipment, you must use it regularly. Runing it monthly will keep the seals and gaskets lubricated. Circulating the oil throughout the engine will help prevent rust. Also you will find issues before they become big problems.
Regular Service – Just like with your car you should get it serviced on a yearly basis. Spark plugs need to be changed along with fuel filters etc.
Proper Storage – When you are not using your generator, be sure to keep it out of the elements. Preferably in a garage or other dry, temperature controlled area. If you are storing it for the winter, be sure to put in a fuel stabilizer.
FAQs About RV Generators
Q: Do I require additional hardware?
A: At the very least, you’ll need an extension cord so you can run the generator away from the vehicle to keep the noise down.
Depending on what you want to charge or power up, you’ll need an adapter, for example for USB devices. Some generators come with extra outlets, but a typical configuration is one 12V DC outlet and two 110V AC household outlets.
If you want to charge a deep cycle battery, it’s almost always more efficient to not connect it to the 12V DC outlet but to connect your charge controller to the AC outlet and let the charger figure out the needed values.
If you don’t have a smart charger or charge controller yet and want to charge batteries, you’ll need a model that is compatible with your batteries.
Q: Is there any maintenance required?
A: Yes, all generators have an internal engine that needs to be checked and maintained, just like the engine in your vehicle. At the very least, keep it fueled up while in use.
But don’t let unused fuel sit in the tank for prolonged periods of time – old fuel is not good for the engine. Generators are typically lubricated by oil, so follow the manufacturer’s instructions regarding an optimal oil level.
A regular check-up and maintenance if necessary will greatly prolong the life of your generator. Some models come with a service meter that will alert you when it’s time. Otherwise, just mark a check-up in your calendar.
Q: Can I charge a deep cycle battery with a generator?
A: In short: yes. A 12V deep cycle battery require DC (direct current), which your generator might be able to supply. However, the voltage and Ampere might not be ideal for the most efficient charging.
It is therefore a better approach to use the charge controller or smart charger of your battery bank and plug it into the 110V AC output of the generator.
That way the controller can regulate the charge as needed and you will top off your deep cycle battery faster and with more efficiency.
Q: How much power can I generate?
A: The power of a generator is rated in Watts, for example 3000W. In addition, you will see a value for running power and one for starting or surge power.
The former is the regular load power, whereas surge power is the value for a short peak. Many appliances draw more power when they’re started up, such as an air conditioner or even a blowdryer.
In order to calculate your power needs, find the wattage for all the devices you want to run at the same time, then add up the individual values.
If needed, do a separate tally for operational and surge power. The values of your generator should be greater than those of your appliances, otherwise you cannot operate them simultaneously.
As an example: your air conditioner has 2000W regularly but a starting power of 2800W. Your other devices amount to 500W. Under regular operation, you need at least 2500W, but while starting up, surge power is 3200W.
A generator with 4000W starting and 3500W running power is sufficient, but leaves you little room to add appliances at the same time. To stay flexible in the future, an even more powerful model might be best.
Q: Which fuel type is best?
A: It depends on your personal preference and your vehicle. The most common and preferred fuel type is gasoline, since it also powers a wide range of RVs and people prefer to only be reliant on one kind of fuel.
A propane generator will limit your runtime to one tank and complicate your refueling. Diesel generators have higher emissions and commonly produce more noise due to a different engine, yet they can produce more power if that is what you require.
Getting the right kind of RV generator for your needs is straightforward if you diligently assess your power needs and weigh in all the other factors as well, such as storage space, generator weight and noise.
Portability is great to have and allows you to use the generator in other situations as well. Yet if you’ll rely heavily on generator power, choose one that you can depend on for enough runtime and electricity.
