Buying Guide of RV Inverter generator in 2022
Now that I’ve reviewed five of the best inverter generators for RV use, it’s time to dive into how you can select the best one for your needs.
In this Buying Guide, we’ll cover everything you need to know to make an informed decision.
Determining your RV’s power needs really depends on the ratings of your electrical appliances and which appliances you plan to run simultaneously.
It’s not recommended to run all of your appliances at once, as that is a sure way to overload your circuit breaker.
The air conditioning unit typically has one of the largest electrical draws of any appliance in an RV.
This is why it can be a good appliance to look at when determining how many starting and running watts you’ll need from an inverter generator.
Many 13,500 BTU RV A/C units require 2750 starting watts and 1250 running watts.
If you have a smaller or larger air conditioning unit, your required starting and running watts will vary.
If you plan to run your A/C with a portable inverter generator, make sure that the generator provides sufficient wattage to handle your unit’s specifications.
Most of these portable RV generators run on gasoline. Some can run on gasoline or propane. Some even run on diesel fuel.
The last type that I know of actually just plugs into a battery pack to recharge once its power capacity has been depleted.
Fuel type is an essential consideration because fuel will be your biggest continuing cost when you purchase an inverter generator for an RV and camping.
The best fuel type for you will often depend on your area and the fluctuating prices of different fuels in that area.
This is why many users that have the budget to do so will purchase what is called a “dual fuel” inverter generator.
These generators can run on either gasoline or propane, but they do tend to be a little more expensive than models that run on gasoline only.
That being said, it’s great to have the option to always choose the more affordable fuel source if you get one of these generators.
Just be aware that wattage ratings can vary depending on which fuel you’re using to power a dual-fuel generator.
Fuel Tank Size
The size of a generator’s fuel tank plays a partial role in how long it can run. Run time also depends on how much load you place on the generator.
But, in most cases, a larger fuel tank translates to a longer run time. The only downside to a larger fuel tank is added weight to your generator when the tank is full.
If portability is more important to you than run time, you might not place a high priority on buying a generator with the largest fuel tank possible.
Parallel capability allows a generator to be hooked up to another (using a connector kit that’s typically sold separately).
Once these two generators are connected, they can provide more power output than each generator is rated to produce individually.
Some of the best RV inverter generators still don’t produce quite enough starting wattage to power up a large RV appliance like your air conditioning unit.
If this is your intention when buying an inverter generator, make sure you choose a model that offers parallel capability.
Most of these portable RV generators are much quieter than old-school generators. They typically produce somewhere between 50 and 60 decibels when operating.
The exact amount of noise output that a generator produces can vary depending on the load you place on it.
Be careful to look into the fine print to understand how many decibels the generator produces under different loads.
Many of their marketing materials provide a minimum decibel rating based on the generator operating at a quarter load.
So it makes sense for you to understand how much noise that same RV generator will produce at full load.
Portability is important for anyone that doesn’t plan on permanently installing a generator underneath your RV.
These RV inverter generators range from just one pound up to almost 100 pounds, so there’s a lot of variability in terms of how easy (or hard) it will be to move your generator around depending on the model you choose.
If you’re looking at a heavier inverter generator, make sure it comes with wheels and a convenient handle.
There may still be times when you need to lift it, but being able to roll it the majority of the way will make your life much easier and reduce the risk of injury that can be related to lifting and moving a heavy generator.
The lighter RV generators should still have at least a handle on top to make them easy to move around.
Because there are many different applications for inverter generators, choosing a portable model is a smart choice.
Because of the price tag associated with many of these RV inverter generators, it’s important to look into the warranty information provided by each manufacturer.
Each one of these camping generators should have some form of warranty to speak of, but the precise details of each warranty will differ.
Understanding the terms of a manufacturer’s warranty is important before you finalize your portable generator purchase to provide power to your RV.
This will dictate your ability to get repairs done on your generator if issues arise. In the worse case, it will also determine whether the manufacturer will replace your generator altogether.
In general, a longer warranty term is better. A longer warranty means you’ll enjoy free repairs and potential replacement for a longer period of time.
A longer warranty also signals the manufacturer’s confidence in their product, which tells you a lot about the quality of the generator before you even buy it.
Deciding on your budget for an inverter generator requires more than just looking at the price tag of the generator itself.
You’ll also need to factor in potential maintenance costs, fuel consumption, and the generator’s expected lifespan.
It should also be noted that online prices can fluctuate very often. If a specific generator is currently just a bit outside your budget, you might wait a few days or check different retailers to find the best deal possible.
So, Which Is The Best Portable Inverter Generator for RVs and Camping in 2022
For anyone that simply wants the best RV inverter generator that money can buy, look no further than the Champion 3500-Watt Dual Fuel Generator. You might even wind up saving some money in the long term because it can run on either propane or gas, depending on which is more affordable.
If you’re looking for an inverter generator with a large fuel tank capacity, check out the Briggs & Stratton P3000 PowerSmart Series. With a 1.5-gallon fuel tank, this generator is capable of running for up to 10 hours at a quarter load and it has an LCD display to tell you when your generator needs maintenance.
Anyone that doesn’t necessarily need a generator to power larger appliances should look at the budget-friendly Ryobi 150-Watt Small Camping Inverter Generator. It’s a great option to take the load of smaller electronics off your RV’s electrical system.
To power a large RV air conditioning unit, you’ll most likely need two inverter generators. One of the best generator options for parallel capability is the WEN 56225i Super Quiet 2250-Watt Inverter Generator. Hook up two of these guys simultaneously for additional power output.
If you really don’t want to bother your neighbors with the sound of your generator running, check out the super quiet Westinghouse IGen2200 inverter generator. When operating, it produces just 52 decibels of noise, which is less than a normal dinner conversation this is the quietest RV generator you can buy.
Frequently Asked Questions
Now that you’ve (hopefully) identified the right inverter generator for your RV use, it’s time to answer a few more of the most frequently asked questions about these generators. This will help you use and maintain your generator properly.
How does an inverter generator work?
To understand the answer to this question, you need to first understand that there are two different types of electrical current: direct current and alternating current (see the movie The Current War for a more complete explanation).
In short, alternating current (AC) is what comes out of our wall outlets and what we use to power our cell phones, computers, tablets, and other small appliances. Inverter generators mimic the power that we typically get from a wall outlet.
This type of generator produces alternating current but it actually converts it to direct current and then back to alternating current before supplying to your RV and/or appliances.
By doing so, inverter generators eliminate the risk of electrical surges, which is why you’ll see many of these generators labeled to provide “clean power.”
What are the benefits of inverter technology?
For starters, inverter technology makes it easier to match the generator’s output with your RV’s power needs.
This technology produces only the amount of current that there is demand for on the circuit. This reduces surge risk and the possibility of electrical damage to your RV and its appliances.
This technology also makes these generators more fuel-efficient. They reserve peak performance for only those moments when it’s absolutely needed, so they aren’t just burning through fuel during the middle of the day when no appliances are running.
That means inverter generators are both environmentally-friendly and friendly to your wallet.
Which are the best brands to buy from?
All of the RV inverter generators in this article come from reputable brands. However, the fine folks at Champion continue to be one of the most well-recognized and respected brands in the generator industry.
A portable inverter generator can fall into that category of RV essentials. You might not use yours for hours on end on every trip, but when other power sources aren’t available, you’ll sure be glad to have it.
It’s better to have it and use it only when needed than to not have it when the moment of dire need arises.
As an RV owner myself, I know how quickly your RV can go from cozy and comfortable to chilly with spoiling food if you don’t have a reliable power supply.
