RV Portable Generator

An RV portable generator, as the name implies, is a type of generator, which is usually easy to transport for their carrying handles and transport wheels. Just like inverter generators, they can charge your house batteries or can supply direct power for 120 AC outlets where you’re plugging your oven toaster, microwave & hairdryer.

The portable generator fits small RV space, while at the same time possesses a powerful engine. It is also efficient for working with less fuel. Nevertheless, a portable recreational vehicle generator is an efficient power source available in different wattages. Choose one based on your rig’s power supply requirements.

RV Generator With Fuel Types

Aside from generator types, including inverter or portable generators, you should know that these power sources are also grouped according to their fuel types. The fuel refers to what the gen-set needs to operate in order to supply power to your RV appliances and electronics onboard.

It is the exact reason to know the different types of fuel that a gen-set can run with so that you can decide which one is the ideal choice. For example, if you’re using diesel on your rig, then you might want to go for the diesel type, and so on. For a guide on the types of generator fuels, keep reading.

Diesel RV Generator

diesel rv generatorThe diesel-powered set runs on diesel that can burn cleaner and emit less fumes and emissions than gasoline does. This type can also produce more power than propane does. As a general rule of thumb, you might want to go for this type if your rig is running on the same fuel for convenience in refilling.

After all, diesel is also safer to store and non-explosive. You can choose from one of the efficient models running on diesel for your camper, motorhome or cabin. On a little drawback, diesel generators can be noisier than the rest of the types based on fuel used.

Liquid propane RV generator

Liquid propane RV generatorWould you like to use a liquid propane RV generator? This type has a longer shelf life although produces about 10 percent less power versus diesel or gas does. But then, the liquid propane for a generator is cleaner and environment-friendly aside from this type of generator having a longer shelf life.

Another thing to know is that propane types are preferred by RV owners who don’t want their fuel going bad because propane has an indefinite shelf life. When it comes to emissions, it also produces little emissions. On a negative, propane generators have a large tank size and are hard to refuel everywhere.

Gasoline RV generator

Gasoline RV GeneratorGasoline-powered generators are affordable, so they’re a common choice for RV owners on a budget. No wonder, its fuel, gasoline, is also cheap. It is also more accessible than propane is. The gasoline-type of generators is also common among RV owners who want to refuel more conveniently.

However, you must know that gasoline is highly flammable, burning faster than diesel does. It also has a shorter shelf life and consumes more fuel than diesel does. Also, gasoline has a short expiration date. It must not also be stored in the RV or garage due to a fire hazard.

What Size Generator Do I Need For RV Camper?

One of the worst things in the world is to end up buying an undersized or oversized generator for your needs. For example, you might not get enough power to support your appliances and RV electronics if you settle for a too-small generator. On the other hand, it is as bad as an oversized generator that proves less valuable if the power it supplies is more than what you need. You need to be careful so that you can save yourself from headaches and some money.

To start, take note of all the 120V appliances that you need to run, and remember that your AC will require the biggest chunk of power. An AC also has a higher starting wattage versus its running wattage. Get the total power requirements of the appliances you need to operate at the same time. You should also take note of the running wattage for each along with the starting wattage of your RV aircon. The sum of this computation will be the average wattage you need. As another tip, you might also want to take a look at the owner’s manual or the sticker attached to each appliance to determine the wattage draw of each appliance.
Size Generator Do I Need For RV

RV Generator Noise Level

RV generator noise levelOne of the most important factors when buying a new RV generator is its noise level, which is determined by its decibel rating. It is used in measuring the sound intensity that the unit can emit. On a decibel scale, the littlest audible sound is 0 dB, which is also the tiniest sound audible to the human ear. In general, we can perceive a sound to be 2 times louder than another one when each of the sources is almost 10 dB apart. As an example, an RV gen-set rated at 70 dB will produce a sound twice as loud as its 60 dB counterpart does. And in another example, an 80 dB gen-set is going to sound almost 4X as loud as what a 60 dB generator can produce.

How To Choose A Generator For RV Camping?

The best RV generator for camping is what you need if you’re looking to enjoy the experience. As you know, there is nothing more frustrating than to have no power supply in the campsite without a hookup or in a remote, undeveloped place. But if you’re choosing a good generator for camping, what are the features to consider?

  • Parallel capability: It must have this capability to ensure you can connect two portable generators to double the power.
  • Low oil monitor: Check that the generator’s engine will turn off automatically if it detects low oil to prevent damage.
  • Power output: Check it on the wattage rating. What is its max power for up to 30 minutes? You must also look for the rated power, which is how much power it can produce for a long period of time. For example, some compact and portable gen-sets are rated with 1000W power, ideal for small lights, TVs and fans. Others are with 2000W for microwave ovens, electric grills and hair dryers. Compare based on your power requirements and figure out your wattage needs for a generator.
  • Weight: Without fuel or gas, what is its dry weight? Portable and handy, these two things are important for an RV generator. You should know how much weight the set has without fuel on its tank.
  • Circuit protection: It is important to ensure generator protection by shutting off the AC power once there short occurs or the load draw is too much.
  • Operation time or runtime: How many hours can the generator run before it needs refueling? However, some manufacturers state only the run time at ¼ of its load. Be able to compare the specs well and consider them only as a reference.
  • Noise level: One of the things to look for is noise level to ensure the gen-set does not only operate efficiently but also quietly. Otherwise, it will be a nuisance not only for you but also for other people in the camping ground. Some gen sets are rated between 53 and 59 dBA at ¼ of its load. Be able to compare based on its full rated load to know how loud really it operates.

How To Install RV Generator?

The following is a quick guide on how to install the RV generator. Refer to it if you’re looking to install it correctly.
Find the best spot to install it in your RV. Do you have a travel trailer? You might want to consider putting it on the A-frame located at your vehicle’s front side, near the hitch and behind a propane tank. Next, you must mount the portable generator by attaching it to the RV’s platform. If the A-frame of your travel trailer is where you’re going to mount the platform, you can place U-bolts over the frame and through the mesh.

However, put the U-bolts through the mesh in the platform’s bottom if you’re going to install the platform on the rear bumper. Be sure to secure the U-bolts around the support structure of the meta channel.

Put the generator on the platform, but its weight must be on the center of this platform. Secure the gen-set to the platform. Place bolts through the holes at the base of the generator if it has those in order to secure the gen set.

Alternatively, you can use ratchet straps if the gen-set has no holes on its base. Hook the straps to the mesh bottom of the platform, and then run those straps over the top of your generator and then be sure to tighten them.
The next thing to do is to wire your generator based on how you want the system to be automated. Plug the shore power cord into the receptacle of the generator, one of the simplest methods to wire it.

Alternatively, you can wire it through a transfer switch that lets you connect two AC power sources.
Follow this process to install your generator. You may also check the instruction manual for any additional or specific maker instructions.

Also, you have to remember that bigger generators are higher-power ones, and it is one feature you might also have to look into when picking the right size for your 50-amp vehicle.

How To Quiet RV Generator?

The RV generator can be noisy, depending on its decibel rating, but there are ways to quiet a noisy set. Two of the most popular materials to silence a generator is the use cardboard or rubber pads used to wrap around the generator to minimize its noise level. For some, they make use of padding under the generator. Others just install the generator under the truck. All these methods have the goal of minimizing the vibrations to make the generator quieter. Rubber pads or cardboard, among other items, is used to divert the noise it generates into another direction away from our ears.

What Oil For RV Generator?

You should use engine oil to lubricate the generator engine and grease for the bearings. For a marine type or large generator, you might want to opt for turbine oil. Fuel additives, however, are for the fuel. On the other hand, you must use coolants or anti-freeze oil for the radiator of your RV generator. And for the generator set, you should use API CJ or CI-4 or CH diesel engine lubricant or oil. If you’re living in a country with four seasons, you might want to consider a SAE 10W40 – 15W40 diesel engine oil along with a coolant that has glycol for antifreeze feature.

Can RV Generator Run While Driving?

Yes, using a portable RV generator is okay while driving, but then it might be better if the set is a built-in generator.

    This site is very helpful for anyone that is new to RVs or confused how everything works. I have had a lot of RVs and i am still learning what is the best way to do it the right way.
    In order to charge my house batteries (two 12 volt agm batteries) I installed an extra alternator on my engine 145 amp and all it does is keep my house batteries charged.If i am boondocking for three or four days, I start my engine and run it at 1200 rpm’s until my volt meter tells me they are close to being topped off.
    I have owned a 2003 Roadtrek Versatile for fourteen years and it still looks like the day i bought it.
