The 6 Best Campervan Power Inverters For 2022 – Ultimate Buyer’s Guide

If you’re in the market for an inverter for your van or RV, we’ll help you decide which is best for your setup and budget. And we won’t leave you juggling between 10 or more options as we’re sharing only the 6 best campervan power inverters and what you should look for when deciding between them. 

In van life, chances are you’ve found yourself in a situation before where you were camping off-grid in a beautiful place, and you realized that, despite how nice it is to not have cell service for a change, your phone needs to be charged.

Sure, you can crank up the van and burn a little fuel plugging into your cigarette lighter car charger. But there’s a better way – a much better way!

Power inverters are becoming standard components of virtually any van electrical system. Whether you are building out your van or have purchased one ready for the road, adding the right size inverter to your power system will allow you to use all of your favorite electrical devices and appliances off-grid that you would otherwise have to run only with shore power.

But picking the best inverter can be a challenge. Not only must you decide between modified sine wave inverters and pure sine wave inverters, but also you’ll want to ensure that you do not pick one that is either too large or too small.

This means before you actually make your decision to purchase a power inverter, you are going to have to determine how much power you use among your AC appliances and then be sure you have a battery bank with enough power supply to meet your power needs.

When we first left on our attempt to drive the Pan American Highway, we had no idea how an RV electrical system worked. Like many van life newbies, we were accustomed to plugging our devices – any devices – into the wall of our apartment and watching the device quickly charge back up. We didn’t even understand the difference between AC power and DC power.

But we had a friend who encouraged us to buy this 600-watt power inverter, and he even helped us connect it to our battery bank. But he didn’t elaborate how it works or even help us understand our possible power consumption on the road.

So when the low battery alarm started blaring at us one day when we were boondocking outside of Sedona, Arizona, we were entirely surprised. And that’s when we took it to heart to learn everything we could about finding the best power inverter and properly size our battery bank.

In this post, we’ll provide you with the shortlist of only 6 pure sine wave inverters from which to choose. And we’re recommending only 2000 watt options as this is typically the best size. All models we recommend have both larger and smaller wattage sizes if you would like one larger or smaller. 

Plus we’ll explain what to look for when purchasing one and share why we chose the one we did for our RV.

On that note, let’s get into our Editor’s Choice and the pure sine wave inverter we chose for our own van life ac power needs.

Runner Up: Xantrex Prowatt SW2000 Pure Sine Wave Inverter

Xantrex SW2000 is a great solution to your power inverter needs. Xantrex’s primary focus is mobile power products and they have been designing and manufacturing them for the past 30 years.

Like its Renogy counterpart, Xantrex Prowatt has a 2000W continuous power surge and 4000W peak surge power. The product is 85% to 90% efficient, which means it will deliver 1800W realistically.

Moreover, it has enough charge to fire up high voltage devices like microwave ovens and fridges (note, you must have an adequate battery bank to support this kind of ac power draw). 

The trait that we love the most is its big digital display. It shows voltage, output power, and error code information and reminds the user when the battery needs a recharge.

The screen is a unique feature because it makes it easier for us to monitor the inverter’s status, and most other devices do not have a screen. Moreover, it also has LED indicators which give you a quick sense if something is wrong. 

We also like that we can trust the Xantrex Prowatt to be a safe device to use. It has low voltage, over-voltage, AC overload, over-temperature and GFCI protection. T

The device alarms the user and shuts down when the voltage surpasses the safe value either on the high side when too much ac power is drawn or on the low side when the battery voltage drops to unhealthy levels. The product also comes with a 2-year warranty.

All these modern features can heat the inverter. So, it has two small fans to keep things cool. The fans are thermostatically controlled which means that the fans kick in when the temperature rises to a specific boundary.

On the downside, the device is relatively expensive and has a remote switch port on the back. But Xantrex does not come with a remote switch, which must be purchased separately (approximately $22).

We also aren’t big fans of the fact that the wires that connect to the battery are exposed and do not have a plastic cover to keep them from contacting other wires and items on accident. This is a minor inconvenience, however. 

Otherwise, this is a great product produced by a great company that stands by its products with a reasonable warranty that we have, in fact, had to use when we had issues with our Xantrex 600W pure sine inverter. 

If you have the extra money to invest in a great 12V inverter this is an excellent option!

How to Choose the Best Campervan Power Inverters

Not all power inverters are created the same. You can’t just pick the biggest inverter without considering your power usage needs and your battery bank capacity.

Space and cost also come into play when making the best purchasing decision. And while the inverters will get the job done (at least for a while), there is definitely a good-better-best inverter out there for you!

Let’s get into the things you should look for when choosing the best campervan power inverter.

Types of Inverters

When shopping for an inverter for your van, you will come across two main types – pure sine wave (“PSW”) and modified sine wave (“MSW”). While we’re discuss the modified sine wave inverter below, we didn’t include any on our list because we like to make sure that we’re recommended the best possible products. 

Modified sine wave inverters are not great for all applications and lack the function and efficiency of pure sine wave inverters. 

Pure Sine Wave Inverters (“PSW Inverter”)

A pure sine wave inverter has the purest AC power. The output voltage and current is similar to a power grid current that we use in our homes. PSW has a consistent negative to positive transition, making it smooth and efficient.

They also have high-frequency technology that does not cause damage to any AC device, whether it’s a standard appliance like a heater and air conditioner or sensitive electronics like a laptop, fridge or microwave.

Pure Sine inverters are comparatively expensive but do not damage your appliances. They are the only kind of campervan power inverter we recommend. 

1000W Pure Sine Wave Power inverter

Modified Sine Wave Inverters (“MSW Inverters”)

Modified sine inverters have intervals in output, from maximum positive to the maximum negative value. To translate, due to the intervals in waveforms, these inverters are not great for appliances that need extra power to start, like motors, fridges, and relays.

Moreover, modified sine wave inverters do not have constant electrical flow, which affects the life and operation of AC devices. For this reason you don’t want to count on a modified sine inverter to run sensitive ac appliances inside your camper van conversion. However, modified sine wave inverters work perfectly with simple appliances like boilers and heaters.

Modified sine wave inverters are pretty affordable inverters, but they can damage your appliances. So, we don’t recommend using a modified sine wave inverter under any circumstance.

Inverter Size (“Wattage Rating”)

The size of the inverter is measured in watts, and you must have seen two power ratings on every product page. The lower one is continuous watts, which is what you can count on to run devices on a continuous time frame. 

And the higher value is called a surge or peak power, which may occur when an appliance is first turned on and requires more power to get started before its power needs taper off. 

Peak/Surge Watts Rating

Peak or surge watts is the maximum amount the inverter can produce. But they can retain this value only for a short time without doing damage to your battery bank and or forcing a shut off.

Regardless of whether you use AGM batteries or a lithium battery bank, it is important to never push your inverter beyond the peak watt rating to preserve your battery life.  

The high power is used to jumpstart big AC appliances like a fridge or microwave. These devices require a substantial amount of power to start up. The early kick is where the surge watts are used for a few seconds.

Continuous Watts Rating

The lower rating usually found on inverter specs is the continuous power or watts rating. It is the amount that an inverter can deliver for regular use. You will compare your power usage with this rating as you look at how many watts you think you will need to run various devices at any given time.

Choosing the right inverter size asks for some research and calculations. Firstly, you will calculate the power usage of your campervan. Simply add the rated power of every electric appliance in your campervan that you would use at any given time. 

Keep in mind that you won’t always run all of your electronic devices at the same time. So consider different scenarios where you may charge a laptop, phone battery and want to run your Instant Pot or hair dryer. Be sure to account for the maximum amount of power you think you would use. 

The answer will be the inverter size you need. But keep in mind that pure sine wave inverters are typically 80% to 90% efficient. So, it must have some extra watts to equal the power loss. 

A 2000W inverter at 80% efficiency is really 2000W x 80% = 1,600 continuous watts. At 90% it would be 2000W x 90% = 1,800 continuous watts. 

Efficiency Rating

A battery bank will surely lose some power when DC power is converted into AC power. The efficiency rating demonstrates the amount of energy an inverter will lose in conversion.

A standard inverter has an efficiency rating of 80% to 90% or more. This means an inverter with 90% efficiency will lose only 10% DC power in conversion.

Efficiency rating is a crucial factor because you are losing essential battery capacity. So, it is vital to get an inverter with 10% to 20% more wattage than required to fill up the efficiency gap.

For example, if your campervan has 1000W usage requirements, consider getting a 1200W or 1500W inverter to be on the safer side. That way when you lose efficiency through the inverter you will still have over the 1,000W that you desire.

Safety Features

Safety features are a valuable part of every campervan inverter. They protect the device from harming itself, appliances and house battery banks. 

Every inverter we mentioned has basic safety features that will keep you and your appliances safe in case of abnormal situations. In these situations, the inverters alert the user with LED indicators and alarms.

Most inverters have over-voltage, under-voltage, overload and short circuit protection.

Expensive and modern devices also have GFCI (Ground Fault Circuit Interrupter). It is a high-speed circuit breaker that cuts the connection in case of a ground fault. Moreover, they have a temperature sensor as well.

You will also find that some inverters will alert you if your connections become loose either to the battery bank or the inverter itself, which is more common than over or under voltage. 

No-Load Consumption

No-load consumption or idle consumption is the amount of electricity an inverter uses when not connected to appliances. Just turning your inverter on will require the inverter to use some battery power not only to power the lights and fan on the inverter but also to have the ability to immediately power any devices connected to it. 

The no-load consumption is an important consideration because power resources are already limited in the campervans. Usually, the idle consumption is pretty low.

For instance, our top pick Renogy uses 0.024 kW per hour. So, usually the values are fairly low, but some inverters can use 1amp per hour or more.

This means they will consume 8 amps to 10 amps out of a 100 aH battery in a night. Moreover, solar panels do not produce any electricity during the night. 

So, you might end up with empty batteries in the morning if you have a cheap inverter, or an inverter that is much larger than your power needs and battery bank will support. 

Make a wise decision and choose a power inverter with the lowest no-load consumption possible. Also, some inverters have stand-by or eco-mode switches to minimize idle power usage. It’s worth paying a little more for an inverter with this feature. 

Dimensions

Size is an important factor for small campervans. While big motorhomes can easily accommodate big inverters, you’ll want to plan an appropriate space for your inverter in your campervan.

The basic explanation of the size can be that a more powerful inverter will take more space. And a more powerful inverter will require a larger battery bank to support it, thus requiring more space for your entire power setup.

So, always measure the space in your campervan before choosing a suitable inverter. Moreover, keep in mind the room for ventilation. It is essential because inverters need some fresh air to circulate with their built-in fans in order to operate properly.

Budget

There is a wide range of inverters on the market and you might get confused with the diversity of price range between them. So, it is recommended to compare the price and specs before making a buying decision.

There are overpriced inverters with outdated and low-tech features. And, on the contrary, you can also get one with some great features at a comparatively low price. 

Modified sine wave inverters are available at somewhere between $50 to $100. But these inverters are not very efficient and we feel like you are wasting your money on them. 

The 12V pure sine inverters lie somewhere in the territory of $250 to $500+. They are efficient and have an excellent power rating. And on the higher end you will not get modern features like a wireless remote control and better efficiency.

Wrapping Up

Choosing the best camper van inverter is not easy. But it can be if you have the right idea about what to look for. So, we hope that after reading the guide you have the proper knowledge to make an educated decision for what works best with your campervan.

We still think our Editor’s Choice, the Renogy 2000W inverter, is the best overall pick and that you won’t be disappointed in its performance in your electrical system. 

Campervan Inverter FAQ

While we covered many of these topics to some degree in the post already, here are the most frequently asked questions about campervan inverters we come across on a regular basis.

Do I need a power inverter for my campervan?

Honestly, particularly if you are investing in a full campervan conversion, the answer is 100% yes. And there are very few situations where we would say that having an inverter is not necessary. 

If you plan to use minimal low voltage appliances and electronic devices that will charge on standard cigarette lighters in your vehicle then you may not need an inverter. Also if you opt to install USB chargers and cigarette lighter outlets as part of your DC electrical system then you can likely skimp on a larger power inverter. 

But when it comes to routine van life you will be hard-pressed to find a van dweller that does not have at least a 1000W to 2000W inverter installed in their van. 

In fact, what we are finding to be more and more common in van life thanks to increased efficiency and reduced costs is a 200-300 amp hour battery bank with 2-3 lithium batteries connected in parallel with a 2000W inverter. 

Couple this with a modest solar system and you have an affordable and effective way to ensure that you don’t have to worry about power usage throughout your van. 

How big of a power inverter do I need for my campervan? 

We have found that most people choose an inverter that is either too large or too small for their battery bank and power consumption needs. The truth is, you can have an inverter that is too large for your battery bank.

Even though you may be able to run larger voltage appliances, you will quickly drain your battery bank to the point it affects the battery life. 

On the flip side, you may find that your battery bank is adequately sized, but that you need or want to use appliances that are too large for your inverter. This happened to us when we first set out on the road with a modest 600W Xantrex inverter. 

The inverter was great and did its job well. And we had enough battery capacity to support using 600W of energy at any given time. But we found that we needed more power to be able to charge multiple laptops, camera batteries and cell phones. 

Our first year on the road we used a complicated system of having to plug/unplug different appliances in different orders for different amounts of time because we did not have the properly sized inverter. 

Now we recommend a standard 200-300 amp hour battery bank capacity (preferably lithium batteries that can discharge much lower than AGM or flooded lead-acid batteries) with a 2000W pure sine wave inverter. 

If you think you will need more power than this and want to go with a larger inverter, then be sure to increase the size of your battery bank as well. And when you increase the size of your battery bank, be sure to consider increasing your solar system and/or consider having to rely more on shore power to keep your massive battery bank topped off. 

There are fancy calculators out there to more accurately gauge your inverter size needs. But unless you have some incredibly extenuating circumstances, it is highly unlikely you would need anything more than 2000W in an inverter.

But a good rule of thumb is to go larger rather than smaller and always remember that it’s worth investing in bigger capacity and better quality batteries to support your power needs. 

How Do I Install A 12V Inverter?

Simply put, consult your specific inverter instruction manual for installation. However, in general, you will want to connect the power inverter to your battery bank either directly (if you do not have a good battery monitor installed) or to your positive and negative battery bus bars.

However you connect the inverter to your DC power source, you MUST include a fuse or breaker on the positive connection between the battery or the inverter or else you risk damaging the inverter, battery and appliances connected to the inverter. 

You will also want to install the invert as close to the battery bank as possible and use heavy gauge wires of the appropriate size as you will be transmitting large amounts of energy through the wires into the inverter.

Again, consult your inverter user manual both for the safe distances and wire gauge for your specific power setup.
