With an inverter generator, you can feel free to keep the lights of your RV switched on. However, there are more details that you must know before getting an RV inverter generator for your RV, and here we have discussed everything you need to know. So without further ado, let’s get started!

What Is Inverter Generator?

Before further discussion, the types of electrical power we have are worth mentioning. There are two types of electrical currents.

  • Direct Current: Current in which the flow of charges is in the same direction
  • Alternating Current: Current in which the flow of charges is reversed periodically.

The current from the wall’s outlet at home is an alternating current. An inverter generator is a generator that tends to provide the power that is typically provided to you through a wall outlet.

How Does It Work?

An inverter generator produces an alternating current and then converts it to a direct current. The current is changed back to alternating in nature before being supplied to the appliances in your RV. This is done to prevent any electrical surges, which is also why most of the inverter generators are labeled as “clean power.”

With the inverter generator, you will have less noise and save fuel as the generator will run at a lower engine RPM. If you are concerned with the working principles of an inverter generator, then you are at the right place.

Inverter generators work by changing the speed of the generator motor. The speed depends on the number of devices connected to the power source and how much current is required. Generators running at a lower speed will save fuel and will be quieter.

You can think of an inverter generator as a power source that only generates the required amount of power. Thanks to the inverter technology, you can now save extra power when needed. These generators are ideal for the environment and best for your bank account as they will save energy and reduce fuel usage.

Is Purchasing An Inverter Generator Worth It?

There is no simple answer to the question. It all comes down to you, your preferences, and the places you travel. However, purchasing an inverter generator has more benefits than getting a traditional one. Here we have listed some of the benefits that will help you decide whether purchasing an inverter generator is worth it or not.

Inverter Generator Vs. Other Power Sources


An inverter generator as it is more efficient than any other power source. Furthermore, if you use other power sources like a traditional generator, you might also need an inverter as the current they produce is direct.

While on the other hand, with an inverter generator, you won’t need an additional inverter. Now, if you are someone who likes their RV on a campsite, then paying the cost of an inverter generator might not be worth it for you.

Ideal For Backup

You can get power cuts even when on a campsite, you need electricity to power your electrical appliances like air conditioners and refrigerators. If you invest in an RV generator, ensure it has great power output. You can also connect multiple inverter generators in a parallel circuit if you require more power in your RV.

An inverter generator will also be lightweight and small, which makes it portable. If you are someone who likes to save as much as you can, it is recommended to invest in an inverter generator as it will save you a lot of fuel consumption costs and supply you with sufficient power as if you were connected to line power.

Factors To Consider Before Buying An Inverter Generator

Only you can get the best inverter generator for your RV. As you know, the minimum power required that you need in your RV. However, there are certain factors that you must look for before investing in an inverter generator.

These factors will help you determine which inverter generator is ideal for your RV. And what are the features that you must look for in an inverter generator when you want to get one for your RV?


The first thing that makes an inverter generator the best for your RV is its size. However, the size of the generator all comes down to your RV and your power consumption. In most cases, inverter generators tend to produce between 2,000-4,000 watts of electricity.

If you are someone who has a small trailer, the best inverter generator for you should be the one that produces 2,000 watts of electricity. However, suppose you are someone who owns a big RV and has a variety of electrical appliances in the vehicle. In that case, you must go for an inverter generator that produces up to 4000 watts of electricity.


Another important factor is the quietness of the generator. You should see the decibels you are looking for when looking for an inverter generator. A decibel is a logarithmic measure. This means that a sound of 70 dB will be twice as loud as 60 dB.

So you need to choose the generator with the lowest sound. Small differences in dB can make a bigger impact on the generator’s sound. A general rule that can be observed is that cheaper generators will have more sound than expensive ones.


Investing in an inverter generator is no joke. The price one has to pay is high. However, most inverter generators bought from a reliable supplier last long. However, it is always good to have a warranty.

A warranty on the inverter generator will help you replace the generator if you have any unfortunate event. So, in this case, the best inverter generator for you will be the one with a warranty that can help you easily replace the whole machine or a part that isn’t working.

Type of Fuel

The fuel types used in a generator are important to know before buying. To get the best generator, you must look for a generator that offers dual-fuel compatibility. Some inverter generators can run on both gasoline and propane fuel. However, you get more power from gas generator, but one can always use the propane option for backup.

Is Inverter Generator Better Than Traditional Portable Generator?

Yes, many reasons prove having an inverter generator is much better than going for a traditional portable generator. To clarify, we have listed some reasons that prove having an inverter generator is way better than going for a traditional one.

Dirty Power & Clean Power

The first thing that a traditional generator offers is dirty power. This means that the further you get from the perfect benchmark of 60 Hz, 120V RMS power, the more dirty power it gets. You might face voltage fluctuation, which can damage your RV’s electrical appliances.

When we talk about an inverter generator, the machine produces filtered power. An inverter generator has a microprocessor-controlled circuit board that regulates the power output. An inverter generator can supply power to sensitive electronics like your television, laptop, and air conditioner.

Inverter Generator Conserves Energy

Whereas a traditional generator can spin at 3600 RPM regardless of the load that it has on it. This means that the runtime is hardly 12 hours without anything plugged in. However, an inverter generator is energy efficient. The speed is based on the load that you have on the RV. An inverter generator will also produce less toxic exhaust fumes.

Weight Difference

A conventional generator is heavy and is made for construction and emergency homeowners markets. The average weight of a generator is usually above 100 lbs. An inverter generator is way lighter, and its weight can be as low as 38 lbs.
