RV Inverter Buyer’s Guide


Having the right RV inverter will play a vital role in your trips being as comfortable as possible. But this benefit is only possible when securing a top tier model. I intend to ensure you get one of these products by discussing what features make up the best options out there.

Each of these discussions will ensure this entire process goes much smoother. Let’s now look at them and see where you stand on these crucial factors.

Inverter Power or Watts Capacity

You’ll need to know this factor to figure out what size unit is needed for your rig. It’s essential to note that these devices have to meet two specific needs or elements when concerning power. The first concerns its peak power or surge, and the other is the typical or usual power.

As you might know, surge will refer to the max amount of power that the inverter can supply. It often will have a short period where it can offer this much power, usually a peak of about 15 minutes.

You should also know that some appliances will require a high startup surge. This quality is especially true for devices, which use an electric motor. As for the typical power, this refers to the power that’s needed to be supplied steadily.

This feature is sometimes known as continuous rating and usually lower than what you’d see for surge rating. I would also suggest any buyer to get a better handle on knowing an inverter’s average power. It’s an aspect that will be much lower than both typical and surge power.

Average power will be a crucial aspect because you can use it to estimate the required battery capacity. Lastly, it’s important to remember when looking at an inverter’s watts, or power is that its sizing should be centered around max peak load and continuous load.

Inverter Power Rating

Another pivotal factor will be an inverter’s power rating. The first thing to know when thinking about this feature is that these devices are available in a wide range of size ratings. You can expect to see units with size ratings ranging from 50 watts to 50,000 watts.

But it’s vital to know rig owners don’t usually use inverters capable of providing more than 5,000 watts. You must also know about your chosen inverter’s max surge before making a firm, responsible decision.

Furthermore, a buyer will need to figure out how long each option can maintain its max surge. This info will be pretty easy to figure out as surge rating is specified with a number of watts per several seconds.

In other words, it shows how many watts the inverter can handle during the amount of time stated. This rating or capacity will change from inverter to inverter. As a result, you’ll need to examine each option before deciding what one can meet your needs.

RV Inverter Types

Anyone looking to buy an RV inverter will need an understanding of the different types. I’ll discuss each of them below to provide a better idea of what one fits your needs. These talks should make this entire process much more manageable and smoother.

Pure Sine Wave Inverters

One of the most common and popular is called the pure sine wave inverter. This type refers to what someone will get from a utility or generator company. It’s a favorite among buyers because you can generate it by rotating air conditioning equipment and machinery. You should also know that sine waves are naturally produced through this rotation.

An excellent benefit provided by this type is all your equipment and appliances will be suitable for it. In fact, all devices on sale right now will be able to work with a sine wave unit. Due to this, you have a guarantee that your rig’s appliances and equipment will work to their full ability.

It’s worth noting that some appliances like motors or microwave ovens are only capable of providing their max output when using sine wave power. Along the same lines, other tools like battery chargers, bread makers, and light dimmers will require one, too.

But there’s one huge problem with this type, which is their price tag. These devices are much more costly than either of the following kinds. However, the results provided by them make the extra money worth paying.

Modified Sine Wave Inverters

Modified sine wave inverters are useful because it works well with the bulk of equipment onboard an RV. But please remember, these units will cause reduced efficiency or power in both appliances and equipment.

Motors found in fans, pumps, and fridges will use more power from these devices because of this lower efficiency, as well. In fact, they will usually use about 20% more power than they’d use with a regular sine wave type.

RVers with fluorescent lights inside their rigs should expect them to be less bright than while using other inverters types. People have also noted these fixtures producing some buzzing or humming sounds when using these inverters to power them.

In general, the noise level produced by these units will be higher than with a regular sine wave. Buyers who don’t care about noise or these issues could find this type to be a practical option, though. It also helps that these devices are cheaper than the regular options.

Square Wave Inverters

But neither of the prior two types are cheaper than square wave inverters. These devices are known for their ability to run simple tools without problems. For instance, tools using universal motors should work with these devices.

However, it’s purpose is limited to this ability. It’s the main reason you don’t see many RV owners with square wave inverters.

Inverter’s Energy Efficiency

Your chosen unit’s energy efficiency will have a large impact on making sure this choice isn’t something you regret. The model should be energy efficient, which means that its use shouldn’t affect your energy usage much. It should also not cause any loss of power or energy in the devices themselves.

Inverter’s Input and Output Voltage

You’ll need to determine each inverters’ output and input voltage, as well. These pieces of info will help you figure out whether the model is a good fit for your rig. In other words, you need to choose a unit that is a fit with the battery’s voltage, which supplies the inverter power.

For instance, people using a 12V battery should choose a 12V DC inverter. You should also pay attention to the AC or output voltage. It’s essential to know that electronic appliances and devices in the US, Canada, Mexico, and some other Latin American countries use 120V AC power. Devices coming from different parts of the world use 220V to 250V AC power.

RV Inverter FAQs

Our FAQ section will cover topics that the previous buying guide didn’t. Any questions still rolling around in your mind should be answered by these following talks. Once you’ve read them, the process of picking an inverter should be as simple as choosing new clothes.

What does the inverter do on an RV?

RV inverters refer to devices with the main purpose of converting low-voltage DC power into standard AC power. Once an inverter is installed, a rig owner will soon realize how useful these products are in ensuring electrical appliances and equipment work onboard an RV.

You should also know these inverters are capable of fulfilling this purpose by working with renewable energy sources or your RV’s battery to power these devices. It ends up being a reliable power source for these appliances inside an RV, car, truck, boat, or truck.

People use inverters to protect their belongings when a power outage strikes, as well. It can work in this capacity because it supplies emergency power to certain appliances like fridges, freezers, and similar equipment.

Advantages of using an RV converter

Several benefits come from using an RV converter within your rig. I’m going to discuss a few of them to ensure you get a better idea of what getting one is a great idea. You can then decide whether buying a top tier model is worth it for your situation.

Efficient Power Source

A person who invests in the top-rated RV inverters, such as a pure sine wave model, can expect it to offer highly efficient power. This power can then be a reliable power supply for most of the devices and appliances onboard your rig. After all, the bulk of them can work using sine wave power.

Modified sine wave types will be able to be this power source, as well. But these options will offer lower power than pure units. It’s also worth noting these modified options tend to run a little hotter than what’s usually expected.

Due to this, someone looking for the most energy efficient option should stick with the pure sine wave models. It’ll end up costing you a bit more, but it’s worth the higher price for anyone looking to buy the best.

When should I use an RV inverter?

RV inverters are handy devices to have within several situations. A common use for them is when people decide to dry camp or boondock in off-grid areas. An inverter for camper use can make it much easier to use your electronics during these fun adventures.

Another instance where an RV inverter would be helpful is during power outages. For example, I camp in an area that encounters heavy rainfall and thunderstorms. So an RV inverter becomes essential to keep my vital components running when I don’t have access to power.

Overall, an RV inverter is a vital device to have on board your rig. You never know when a campground won’t have reliable power access.

How much does an inverter cost for an RV?

Most RV inverters will cost anywhere between $150 and $300. Of course, where a certain option falls will depend heavily on its features and other vital components. But you can usually find a solid 2500 watt inverter or RV pure sine wave inverter in the middle of this price range.

So RV inverters aren’t an overwhelming purchase like other RVing equipment. In other words, it isn’t like buying a new solar generator or AC unit.

What is the difference between an RV inverter and converter?

Understanding the difference between an RV converter and an inverter isn’t too tricky. It boils down to converters changing AC voltage to DC voltage. Meanwhile, an inverter does the opposite by converting DC to AC voltage.

You can even find an RV inverter converter combo device that provides both functions. But these models will cost a bit more than traditional singular options.

What will a 3000-watt RV inverter run?

A 3000 watt RV inverter can run more devices than a rig owner might expect. You can simultaneously get away with running a fridge, coffee machine, lighting, charging various smartphones, and a few other devices. You can plug in almost any electronic equipment until it surpasses its maximum limit.

Won’t Require Gasoline or Fuel

One of the major benefits provided by an RV inverter comes from its ability to convert battery power. This aspect ensures a rig owner won’t need to use gasoline, which means a lot less hassle on your part.

I mean, you’ll no longer need to store gasoline for power purposes anymore. This situation sounds like a huge win to me. It’s important to remember it’s only possible to store gasoline for one month before it becomes unusable.

As a result, it becomes rather evident that using an inverter instead of a gasoline power generator sounds like a smart option. It’ll keep you from having to always keep storage of fresh gasoline around for potential power outages.

Low Noise Level

Generators are very noisy, which tends to be the main complaint among people who have them. The right RV inverters don’t have this issue and run without making a single peep. It’s a blissful experience rather than a headache-inducing nightmare.

Honestly, who would want a noisy generator running inside a campground? This situation sounds terrible for everyone, including your neighbors. You can reduce the chances the people end up loathing your existence by investing in an inverter.

What size inverter do I need for my camper?

Figuring out the perfect inverter size will depend on how you plan on using this device. It’s crucial to avoid buying an inverter that’s either too large or small. Both these situations can lead to problems no rig owner wants to endure.

The first step in determining your ideal inverter will be remembering these units will be rated in watts. As a result, you can find these devices in various power ranges and sizes. In fact, they can run from 75 to 5,000 watts.

People who do most of their camping in campgrounds might be fine without an inverter. After all, you have a constant supply of electricity in these communities. But you might find your RV adventures more convenient with having an inverter and batteries capable of meeting your 120V needs.

If you fall into this category, the next thing to assess is the inverter’s output capacity. You must find a model capable of handling the loads put onto it. So please, remain aware that these devices come with two capacity ratings, the continuous output rating, and surge capacity.

Buyers should also keep in mind that these inverters are now available in portable and small sizes. These devices are the ones capable of plugging directly into a cigarette lighter or 12V outlet. Once plugged in, these smaller inverters will supply power or electricity to your rig’s entire electrical system.

These smaller units are capable of being installed permanently, as well. Some buyers find it more appealing to go with chargers or inverters that are found in most RVs out there. They don’t only function as inverters but serve as a battery charger and transfer switch in one convenient unit.

You see, the unit will work as a battery charger each time they’re plugged into an electricity source or when a generator is being used. These inverters will also be capable of storing DC power without any source of electricity or generator power. As a result, they can automatically transfer power into a battery charger.

How to install an RV inverter?

Most people will love to find out installing an inverter isn’t too tricky. In most cases, it’s a task that a person can do by themselves without help. Buyers who get a small inverter that operates at around 75 watts can simply plug into the outlet for your cigarette lighter.

But larger units will have a few more steps to do as these inverters will need direct wiring into your batteries. People who do choose this method will need to do it very close to the batteries, which will help lessen the risk of losing any voltage.

I would advise checking the device’s manual as it should provide a suggestion about the right wire size. There’s no reason not to follow this suggestion, but it wouldn’t hurt to go for a larger wire size as a precaution.

The actual install process has a few ways of being done. The most effective, but costly option would be by connecting your inverter into your rig’s AC distribution box. You can combine these two things with a transfer switch.

But please remember, the type of switch will differ depending on your inverter’s power and whether you’re using a generator. If shore power is available, the transfer switch will choose it without issue.

If shore power isn’t available, the transfer switch will choose the inverter’s power. Some people prefer to choose this method when doing the install. But selecting this route means you shouldn’t power up your RV converter using the inverter. You can avoid this happening by using a split distribution panel.

You can also install an RV inverter using an extension cord. This process consists of running the extension cord from your inverter to any device you want it to power. Of course, this method is very inconvenient, as you will have to plug and unplug devices constantly.

Modified vs. pure sine wave inverter: Which one is better?

As I mentioned previously, a pure sine wave inverter is the more effective option than a modified model. Pure sine waves will be able to offer a highly efficient power source for your rig’s appliances that a modified unit can’t match.

But the price difference between the two types does make many buyers settle for a modified sine wave inverter. Honestly, pure sine wave models are much more costly, which makes them a hard pill to swallow for bargain buyers like myself.

However, the results provided by them are hard to argue with as a consumer. These devices are truly the better option without any doubt. Due to this, I’d suggest taking the bullet and spending a little extra to obtain one.

It won’t be a decision any rig owner will regret after they see the results provided by them. It’s a drastic difference and one worth paying for as an RVer.


After reading this article, picking the best RV inverter shouldn’t be much of an issue. I would just suggest using what you’ve learned during the process. If you do, I promise the right choice should become abundantly clear.
