What is an RV Inverter?

An RV inverter is an electronic module that converts DC power to AC power. With this hugely convenient device, you can power appliances that need 12V AC shore power or items that would normally need a generator or a power outlet. 

Both AC and DC create a current that is a flow of electrons. DC or direct current essentially flows in one direction. It comes from a solar panel or a battery and has a constant flow of 12V. AC or alternating current refers to the current that you get from shore power or a generator. It changes direction and is usually around 120V.

Some appliances are designed to run off DC. This typically includes those items that require a low voltage, such as the water pump, vent fans in the kitchen and bathroom, and smoke detectors. Electronics that run off AC include items that need a higher voltage, such as an air conditioner, microwave, refrigerator, or TV. 

If your RV is not fitted with an inverter, you will need a power generator or shore power to charge laptops and phones, use various appliances, and to watch TV. However, if your RV does not come with an inverter, you can easily buy one yourself. The important thing is that if you are planning on boondocking, you will need a good-quality inverter to power the various appliances on your RV that need AC power. 

Aspects to Consider When Buying an RV Inverter

There are a few aspects to keep in mind when searching for your next investment, such as the watts it can release, power rating, voltage input, and output, as well as the energy efficiency.


This part is essential in deciding what size of inverter you’ll need for your RV. It has to meet surge power, and usual power requirements as many appliances within your RV can only work with a high surge power. This surge power is the maximum level in which the inverter operates. The usual power is just the amount that will be provided continuously to your appliances after the surge is over.

Power Rating

Another consideration to make that’s similar to the previous aspect. You can find models that provide power between 50 watts and 50,000 watts. Most RV owners won’t need more than 11,000 watts for their appliances.

Input & Output Voltage

Understanding your RV’s capabilities is another way to find the perfect choice, this means knowing the input and output voltage. For example, if you have a 12V battery, you will be able to buy a 120V inverter.

Energy Efficiency

Energy efficiency can save you a lot of time, effort ,and money, but only when you find the right product. You should always find the most efficient inverter which can still provide the same amount of power to your appliances.

Comparison Overview


With so many devices available for your RV, how can you tell which is best for you? Here are some helpful comparisons.

What is the Difference Between a Generator and an Inverter For an RV?

The main difference between a generator and an inverter is the way they operate. The former produces electrical power to run the appliances on an RV, while the latter uses a microprocessor to convert DC power to AC.  

If you are unsure whether to use a generator or an inverter for your RV, the following differences will make it easier for you to choose:


Inverters are highly portable and can be stowed away easily. They can be easily transported as they are small and lightweight. Generators, on the other hand, are quite heavy and require wheels and a big metal frame for the relocation. Although they can be moved from one place to another, they lack the convenience factor afforded by inverters.   


Generators, particularly cheaper ones, produce a lot of noise, which can be a nuisance. Inverters are usually silent and can be used at campsites without causing any disturbance among other campers.


An inverter does not require fuel, as its main function is to convert battery power. This means less hassle as you do not have to store large amounts of gasoline to have power all the time. 

A generator runs on gasoline, but you can only store it for a month. Therefore, if you use generators, you will have to make sure that you have enough supply for your travels.    

RV Inverter vs. Converter - What’s the Difference?

Inverters take the direct current and turn it into alternating current usually from a battery. Whereas, converters take the alternating current from an electrical device and convert it into direct current. 

How to Install an Inverter in an RV

The installation of an RV inverter differs from model to model, depending on the make and type of product that you choose. However, the general steps of installation are as follows:

1. Choose a place to install the unit, preferably close to the battery, as it will help reduce voltage drop. Also, it should have proper ventilation to help heat dissipation. 

It is best to avoid putting the inverter in the battery department because the acid present in a flooded lead-acid battery can produce hydrogen gas. As a result, the inverter can spark and create an explosion.  

2. After choosing the perfect spot, connect the inverter to your RV. If you have a plug-and-play model, you can just plug the cable into a 12V outlet, and you are good to go. 

3. Connect the unit directly to the battery with the help of the cables provided. Cables fitted with battery clips, whether O-ring or clamp style, will make it easier to connect the RV batteries and inverter.    

If you choose a unit that needs to be hardwired to the RV’s electrical system, then it will require additional installation work. For example, you will have to do the CFCI wiring and install the transfer relay. However, for such models, it is best to use a professional.  

How to Wire an Inverter in an RV

Wiring an inverter in an RV can be as simple or as complex, as you want. You can connect the inverter into your RV’s electrical system or you can place the inverter close to the batteries and use a breaker or a fuse to connect the two. Then you can simply plug in any appliance that you want to power directly into the inverter.

If you want to know more about wiring or installing an inverter in an RV, the following tutorial will guide you on the correct procedure.


Finding the right choice can be a daunting task when you don’t understand the jargon or technical aspect behind it all. All you need to remember is that most RV manuals will provide you with all the information you need to find a compatible inverter.

You might need to fork out a few extra bucks to get the most efficient model, or you could be happy with your appliances working a little slower to save on costs. Whatever choice you make, hopefully, this review makes it a lot easier for you.

People Also Ask

This section is to help anyone understand the jargon, any in detail parts of the buying process, or how these products work. They can be quite complicated, and hopefully, this part can help ease your mind or answer any questions.

Does an Inverter Draw Power When Not In Use?

Yes, an inverter draws power from the batteries when it is turned on and is not in use. This can be from 0.02 to two amps, depending on the model. If your inverter is turned on with no load attached, then it will draw almost one amp/hour from your batteries. Therefore, it is best to turn off the inverter when not in use to protect the battery from draining.  

Where Is the Inverter On My RV?

The inverter is usually close to the batteries as it is connected to it with cables. Some RVs are designed with a standby inverter that is permanently wired to the RVs electrical system, thus ensuring an uninterrupted flow of current directly to various appliances.

Why Do I Need an Inverter in My RV?

Most things in an RV draw DC power while some residential appliances, such as TV, space heaters, residential refrigerators, microwave, etc. need AC power to run. An inverter is an excellent device to have on hand, particularly if you are camping in places that do not have electricity hookups or are boondocking as this will allow you to run your appliances by converting the battery’s DC to AC.   

How to Turn on a Power Inverter For an RV

RV inverters can be switched manually with an on and off button while some are designed with a remote switch, both wireless and wired. 

Troubleshooting an RV Inverter

RV inverters are particularly reliable and do not need much attention from owners. However, they are prone to experience some kind of trouble. A few of the most common problems and their solutions are listed below:

Bad House Batteries

RVs are fitted with one or more lead-acid batteries to run 12V accessories. These also provide an inverter with the necessary current required to produce 110V AC. These batteries, however, do not last long, especially if they are neglected or mistreated. Moreover, they can fail due to aging.

In such cases, the batteries lose their ability to hold a charge, which prevents them from providing sufficient power to accessories. Replace your battery with a new unit to ensure continuous power. 

Blown Fuses

A blown fuse can disrupt the current flow, which in turn can hinder the performance of the inverter. Consult your RV’s electrical diagram to find out the location of fuses. Evaluate each fuse separately to determine which one is blown. It is best to use a professional to replace it as this reduces the risk of electrical fires. 

Should I Leave My RV Inverter on All the Time?

Keeping the inverter on ensures continuity of power. If shore power is interrupted or if you leave the campground, your AC appliances will keep on working. However, when you store your RV, make sure the inverter is turned off as it is directly connected to the batteries and will continue to draw power unless it is switched off.

How to Check an RV Inverter

An inverter keeps the RV battery charged when it is connected to external power. In case of a faulty inverter, you will not be able to run your accessories. You can determine the health of your inverter by checking it thoroughly.  

  • Remove the battery cover and set it aside. Use an adjustable wrench to disconnect the battery cable. 
  • Connect your RV to an external power source. 
  • Run the 12-volt accessories such as lights and water pumps. If they operate normally, your inverter is functioning perfectly. Also, make sure that the inverter cooling fan is working properly as it protects the inverter from overheating. 
  • Unplug the RV from the external power source, stow the power cord, and replace the battery terminal. 

What Does an RV Inverter Do?

An inverter is a device that takes Direct Current (DC) from your RV battery and turns it into Alternating Current (AC) which can then be used to power appliances such as microwaves, ovens, and air conditioners. Multiple types have different limitations.

Do You Really Need a Pure Sine Wave Inverter?

You don’t need one. However, other types of inverters aren’t as powerful or efficient. If you don’t mind sacrificing power to save some money, go ahead and by a modified sine wave Inverter. Keep in mind that square wave inverters are the least powerful and are best used for tools and small appliances.

What Can I Run on a Modified Sine Wave Inverter?

You can run most household appliances like refrigerators, ovens, and air conditioners. However, these products won’t work to their optimal performance as this type doesn’t consume your RV battery power efficiently. This problem is mainly for any electric motor appliances.

What Size of Inverter Do I Need For My RV?

The size of your inverter depends on the capabilities of your RV battery, you should check the input and output for the battery. For example, a 12V battery can churn out 120V of power. If you can match them effectively, you will get the maximum the Inverter can give.

How Long Will a Battery Last With an Inverter?

There are a few variables to consider before hooking straight up to your RV battery, you would need to know how many amps per hour your battery gives off. For example, a 90-hour amp rating (400 Watts) can survive up to two hours. If you have a deep-cycle battery, you would be able to use all of the battery and then recharge for further use.
