How Do You Pick The Right Propane Generator For Your RV?
So there are six excellent propane generator alternatives for RV usage.
But first, let’s look at the most significant characteristics that will help you distinguish between various models and, finally, choose the generator that’s most suited to your requirements.
#1. Wattage Ratings
The first step in selecting the correct generator is determining how much electricity you’ll need to operate your RV’s main systems.
Consider the devices and appliances you’d most want to be able to use if you were to depend only on generator power.
Refrigerators, water pumps, central heating systems, water heaters, air conditioning units, fans, and anything else you think necessary for living comfortably in your RV are examples of these items.
The wattage ratings for all of your RV’s appliances should be listed somewhere in the owner’s handbook.
Once you’ve found these ratings, examine the highest beginning or peak wattages of the appliances that use the most electricity.
You may get a good idea of how much watts you’ll need from a generator by adding the beginning wattages of your two or three biggest appliances.
Even if you choose a generator that can handle it, keep in mind that you shouldn’t run all of your appliances at the same time.
#2. Convenience
You won’t have to worry about mobility if you want to put a new propane generator in an underbelly compartment of your RV.
In this scenario, all you have to do is double-check that the generator you chose will fit inside the compartment.
You must also ensure that the compartment can withstand the weight of the generator.
However, if you want to utilize a generator for a fixed RV while still being able to move it about for other uses, you’ll need to be okay with the weight and proportions of the generator.
A wheel kit, which enables you to roll rather than lift a bigger generator, is a nice feature to check for.
Smaller units should always come with handles, but if they don’t, this is an early red signal that moving it around will be more difficult than required.
Consider how far and how frequently you’ll need to transport the generator when determining its weight and size.
#3. Flexibility
It’s usually a good idea to see whether a generator may be used for several purposes.
Features like as dual-fuel capability, mobility, and the capacity to deliver numerous alternative power connections are examples of this.
Some generators, for example, may provide both 30 amp and 50 amp power connections.
If you now have a 30 amp RV but want to convert to a bigger RV with a 50 amp hookup in the future, this may be handy.
Of course, the converse is true for anybody who plans to downsize their RV in the future.
A smaller propane generator is also more adaptable since it may be used for purposes other than generating electricity to your RV.
It may come in handy for tailgating, hunting, or providing additional electricity during a backyard party.
Make sure the generator you choose is adaptable enough to satisfy all of your demands before you buy it.
Only you know your specific demands (and they’re sure to vary! ), but it’s still worth thinking about how your generator can and will adapt to your lifestyle.
#4. Maintenance
A generator’s simplicity of maintenance is another factor to consider before purchasing.
While the expectation is that you would handle your generator with such care that major maintenance difficulties will be rare, regular maintenance will always be required to assist prolong the life of your generator.
Portable generators are usually the most convenient to maintain since they’re easy to transport and have access from all sides.
This enables you to quickly identify and fix any maintenance problems that arise.
However, installing a generator in your RV’s bottom compartment might make maintenance more challenging.
That is why generators designed expressly for this sort of installation exist.
All of the key areas for maintenance may be accessed from a single panel on these generators.
So, Which Is The Most Appropriate For You?
The wonderful thing about RV living (and, indeed, life in general) is that there is no one-size-fits-all approach.
So I’ve taken the effort to recommend some scenarios that each of the six propane generators I discussed above might be most suited for.
Look into the Cummins Onan 2500 Watt LP Vapor Generator if you want to put your faith in a generator brand that is recognized for its quality and dependability.
The Onan brand is well-known in the generator sector, and this model is also one of the quietest models on our list.
Don’t underestimate the benefits of the ALP 1,000-Watt Generator when buying for a generator on a budget.
While it has a lesser total wattage, this generator has a parallel capability, which allows it to provide more power to your RV.
The Champion 3800-Watt Dual Fuel Generator is ideal for those who just want a generator that is simple to start when they need it most.
It features an electronic start, which eliminates the need for a crank start, and it can operate on either propane or gasoline, depending on which is most cost-effective.
The All Power America APG3590CN propane generator is an excellent alternative for RV owners looking for a powerful but portable generator.
It provides enough of running and starting wattage while also being able to be moved into a new position if you need to reposition it.
The Firman H08051 propane generator is a good option if you want a generator with a lengthy run duration on its own built-in fuel tank.
It includes an eight-gallon built-in tank with a 12-hour run duration and can be connected to an external propane tank for additional run time.
The DuroMax XP12000EH model is ideal for those who simply want to get the most power out of their propane generator.
This generator is also ideal for RVs that need a 50 amp electrical hookup.
FAQs
Generators aren’t the most difficult pieces of machinery to operate.
They do, however, require some getting used to.
In this part, I’ll address a few typical questions to assist you in selecting and maintaining the generator of your choice.
How can I figure out how much electricity I’ll need?
Adding up the operating and starting wattages of all the appliances in your RV is the simplest approach to establish your RV’s wattage requirements.
To make things simpler, concentrate just on the beginning wattage, which will be greater than the running wattage.
However, it’s unlikely that you’ll be using all of your appliances at the same time.
So, if you just want to concentrate on one or two appliances, examine the ones that are most important to the running of your RV.
Microwaves, air conditioners, and refrigerators are all examples.
Is it possible to use these generators with an external propane tank?
Yes, to put it simply.
However, not all of these generators have this feature, so be careful to look at each model separately for a more accurate response.
A generator that comes with a length of propane fuel pipe built for that purpose is a good clue that it will function with an external propane tank.
What is the difference between a dual-fuel generator and a single-fuel generator?
It’s exactly what it says on the tin: a dual-fuel generator.
It’s a generator that can operate on two different kinds of
fuel at the same time, but not at the same time.
You’ll have to choose between the two fuels, and some generators may produce less energy while operating on propane than when running on gasoline.
The most frequent fuel types utilized by dual-fuel generators are gasoline and propane, however there are certain versions that may operate on diesel.
What are some ‘best practices’ for generator maintenance?
If you’re staying in your RV for a while, it’s a good idea to use your generator every two weeks or so.
At the absolute least, once a month, activate your generator for a few hours.
Ascertain that the oil reservoir is filled to the proper level.
Check the fuel level and do a visual examination to ensure that all components are clean and nothing seems to be out of place.
Conclusion
As someone who has previously overwintered in an RV, I can tell you from personal experience that heating my RV with propane was much more cheap than utilizing an electrical heating source.
RVers who aren’t on the grid, on the other hand, don’t have the option of utilizing a steady supply of AC power for heat.
For some RVers, using a generator is a must.
It may also be a lifeline for those of us who live full-time in an RV off the grid.
In any case, it’s an important source of RV electricity, and propane generators may be a more fuel-efficient way to get the job done.
I hope you’ve learned something new about purchasing a propane generator for use in an RV, and I wish you nothing but the best on your future RV trips!
