Buyer’s Guide to Buying the Best RV Inverter

Finding the best inverter for your RV can be pretty tough, especially when you’re not 100% sure exactly what you are looking for.

Read through our buyer’s guide to RV inverters and find out just what you need to keep a lookout for when choosing a new inverter for your motorhome.

Price

You’ll find a wide variety of RV inverters at hugely varying prices. For a start, pure sine wave inverters are more expensive than modified sine wave ones. So, if you are looking for a bargain, you’ll want to make sure you can run everything you need off a modified sine wave model.

Secondly, the higher the Wattage and the greater the number of features, the more you’ll pay. Obviously, durability and build quality come into play too, a high quality inverter costs more to make. With higher priced models, you can also expect better customer service, although this isn’t always the rule.

For small RV inverters with a low power output and minimal features, you can get away with paying around $100. However, unless you have a small camper or very modest needs, you’re probably going to be better off spending more money.

Around $200-$300 will get you a good standard model that should have a decent wattage, a good warranty, and plenty of features. While most high wattage inverters in this price range will be modified sine wave models, keep your eyes peeled and you will come across the occasional pure sine wave inverter at the upper end of the price range.

Above $300-$1,000 plus will get you an industrial-strength inverter with sine wave technology, a high wattage output, and plenty of premium features. However, also bear in mind how much you are likely to use your inverter and whether this represents good value for money for your actual needs.

Power or Watts

One of the main priorities when choosing a new RV inverter is to make sure that it will be sufficient for your needs. If you can’t run what you need to run, then it’s not going to get the job done.

On the other hand, you need to be realistic, as the inverter is just one part of the chain. You will also need deep discharge batteries to ensure you don’t run out of power, as well as the appropriate connections.

Think through all of your essential appliances that you want to be able to use when you’re not hooked up. Once you have come up with a reasonable list, go over it and decide if any of these items are going to need to run simultaneously. You need to come up with a wattage that reflects the maximum draw you are going to need.

Write down the wattage requirements for each appliance on your list, you’ll need to note both the start up and the continuous Watts required to run each item. Then match your needs to your inverter’s power rating.

To be on the safe side, add an extra 20% to account for energy losses and a bit of leeway, then round up to the nearest inverter. For example, if you have a running Wattage of 2,500W and a surge Wattage of 5,000W, then you could safely opt for a 3,000W inverter with a surge capacity of 6,000W.

Power Rating

Your RV inverter will have two power ratings – the first for continuous running power and the second for start-up or surge power. Most electrical appliances require a lot more Watts to start up, much more than they do to run. For this reason your inverter should be able to run for several seconds at a minimum of double its continuous power rating.

Note the use of the word “rating”. In real-life scenarios, you may find that your inverter doesn’t give out quite the same performance as claimed by the manufacturer.

Also, a lot depends on your appliances and their draw. If you are planning on powering any large, power-hungry appliances, be sure to double check that you will have sufficient surge power to get them started, as well as keeping them running.

Energy Efficiency

The most energy efficient RV inverters are pure sine wave inverters, some of which operate at around 90% efficiency on a full load. Modified sine wave inverters are less energy efficient than pure sine wave ones.

Bear in mind that regardless of your type of inverter, you will still lose some energy during the conversion from DC to AC, mostly to heat. So every inverter will draw more Watts from your battery than it can actually deliver.

Input and Output Voltage

RV inverters normally run off 12V batteries. While there are 24V inverters around, RVs generally already run off a 12V DC battery supply for their lighting, water pump, refrigeration etc, so it makes sense to opt for an inverter that can be integrated into the existing electrical system.

To power your other appliances that require AC, your inverter will put out 110V-120V to match shore power voltage. This will ensure that all of your AC powered appliances function correctly.

Ease of Installation

If you are going to install your inverter yourself, then make sure you get one that is not going to be overly complicated. There are different ways to connect different models. Some are hardwire only, whereas lower capacity models may lack hardwire connections. Also keep an eye out for any mounting brackets and installation kits.

If you are uncertain about how to set up your RV inverter, you could always get a professional to do it for you. In any case, unless you’re fully clued up already, it can help to read through the owner’s manual and installation instructions before making your purchase. Not only will this give you a better idea of how you’ll need to proceed, you will also be able to assess whether or not you need any extra hardware or equipment.

Durability

It’s important to have an inverter that you can rely upon. If you get stuck out in the backcountry and run out of battery on your phone, you’ll need your inverter to work.

Also, as you will be relying on your inverter in situations where it’s not possible to run off shore power, it’s important that it functions well, or else your entire trip could be completely spoiled.

To gain a better idea about your inverter’s durability, check out the manufacturer. If they have every confidence in their product, they should provide a good warranty of at least one, if not two years.

If you have your doubts, don’t hesitate to reach out to their customer service department. This can often give you a good idea of just how proactive they really are.

Safety Features

You’ll want to look out for an inverter that has an independent safety certification, such as UL 485. UL stands for Underwriter Laboratories, a third party certification company. UL 485 is the current safety standard for inverters installed in land vehicles.

As all electrical installations can potentially be very dangerous, it is important that your inverter has a range of safety protection functions, including overload, under/over-voltage, short-circuit and surge protection.

As inverters can get very hot when in use, it is important that they have cooling fans and adequate ventilation.

What is an RV Inverter & How Does it Work?

An RV inverter converts DC power from your battery to AC power.

When your RV isn’t connected to an electrical hook up, you can only run a very limited number of items in your coach through the battery’s DC supply. Normally just your lights, water pump, and your radio. To use anything else, you need to hook up your RV to AC power.

DC stands for direct current and it’s the type of current that your 12V batteries output to your RV. Shore power is AC or alternating current, where the current very quickly and very frequently switches from positive to negative, creating what is known as a sine wave.

Your regular appliances need AC power to run, so if you want to use your microwave, for example, while you stop off for lunch, you’ll need to convert your 12V DC to 120V AC, and an inverter does just that.

Today’s sine wave inverters use toroidal transformers and circuits to transform direct current into alternating current, as well as increasing the voltage.

Types of RV Power Inverters

There are three main types of power inverters, here’s all you need to know about each one.

Modified Sine Wave

Modified sine waves are a popular choice as they are much cheaper than sine wave inverters.

AC power alternates, changing direction 60 times per second at 60Hz. This changing direction creates a smooth wave, known as a sine wave. When your modified sine wave inverter changes your battery DC power to AC, it doesn’t quite form a smooth wave, rather a jagged series of abrupt transitions from positive to negative. This is what is known as a modified sine wave.

While modified sine wave inverters are not as high performing as sine wave ones, losing out on efficiency and being less suitable for powering audio-visual equipment, they are generally acceptable for most day to day appliances and they are also much cheaper than sine wave versions.

Note that there can be some running differences, for example they can alter your microwave cook times. However, plenty of RVers rely on modified sine wave inverters for all of their off grid needs. Just be aware that you may be unable to power certain sensitive appliances with one, so double-check your needs before making your purchase.

Sine Wave

Also known as pure sine or true sine inverters, sine wave inverters are the best type of inverter around.

Utilizing the latest, high-performance technology, these inverters replicate the exact same waves you get in your home AC electricity supply. Not only does this mean that a sine wave inverter can run all of your equipment, just the same as if you were plugged into shore power (wattage and battery constraints aside), it also ensures higher levels of efficiency so you get maximum levels of power.

On the downside, given their superior build and technology, sine wave inverters are more expensive than modified sine wave inverters. While you get better performance from LEDs and microwaves with a sine wave inverter, you can still use a modified sine wave model and achieve adequate performance levels.

However, for audio, satellite systems, and some video equipment, you may need a sine wave inverter for correct functioning. If in doubt double check your appliance’s specifics before ordering.

Square Wave

Square wave inverters are not suitable for powering your RV appliances.

Like modified sine wave inverters, they form a jagged, boxy wave, but much more so. This is not only inefficient, it can also be dangerous, causing your appliances to malfunction, break, or heat up. As they can lead to electrical faults and fires, square wave inverters are banned in some countries.

In general, square wave inverters are only really suitable for use with motors and they are not recommended for household use. They are also very noisy and have a poor safety and reliability record.

Final Thoughts

With so many RV inverters to choose from, it can get a little confusing. If you’re struggling to pick the best RV inverter for your rig, go back over our buying guide, work out your Wattage needs, then take another look through our top RV inverter reviews.

If you are looking for a sine wave RV inverter with plenty of power, you’ll definitely want to take a second look at the Go Power Industrial Pure Sine Wave Inverter.

About Karan Riley

I am the owner and main contributor to RV4Campers. I first got bit by the RVing bug when I joined a friend who was into Van Life for weekend getaways. It became apparent very quickly that this was a style of life I enjoyed and wanted more of, so it wasn't long before I had my own travel trailer. I didn't have a lot of money to throw around back then so I did lots of research into all the gear and gadgets. And this is how my RV passion exploded, I've now spent countless hours playing around with many different bits of kit and reading user manuals. And it's this wealth of knowledge I bring to RV4Campers.
