Best RV Inverter

[amazon fields="B078HFGVY2" tracking_id="cotor-bg-best-rv-inverter-20" value="thumb" image_size="large" image_align="center"]

Out of our list of nine inverters, we chose the BCI 3,000-Watt Pure Sine Wave Inverter as the best RV inverter because of it’s incredibly versatile, and its attractive price. While we would like a longer warranty than one year, this little issue is out-shined by everything this motorhome inverter has to offer, plus the fact that it lasts a long time anyway if you take care of it.

This is one of few inverters for RV use that can be used effectively in freezing temperatures. That alone sets it apart from competitors. It’s also safe for your cellphones, laptops, and other sensitive electronics. While it doesn’t have a USB port for these types of electronics, you can power them through the AC sockets with peace of mind.

If that’s not enough, the inverter is lightweight and small. It measures 16.9 x 7.1 x 5.5 inches and weighs just under 15 pounds. Many 12v inverters that perform at this caliber of quality are bulky and heavy, so we appreciate the ease of use with this inverter.

How to Choose a Great RV Inverter

If you’re reading this article, you probably already know what an inverter is, but just in case you don’t, we’ll give you a basic definition. An inverter converts the direct current power from your 12-volt RV deep cycle battery into alternating current (AC) power so that you can use your 120-volt appliances inside the RV. The RV inverter holds power from the battery and sends it to single sockets or to a breaker panel.

Some recreational vehicles come equipped with power inverters, but many do not. In the case of the ones that don’t, you’ll more than likely need an inverter at some point in time. This can be avoided if you have a generator that has a built-in inverter. However, it may be more cost-effective to get an RV power inverter rather than a generator. Keep in mind that the more power you need, the larger you need your RV power inverter to be.

Now that you know what an inverter does will tell you what you need to know to choose the best inverter for campervan or RV use.

What is an Inverter & Why Do You Need One?

An Inverter for your motorhome or camper is a device that will transform DC power from power sources such as solar panels or your house battery into AC power. If you plan to do any boondocking, or camping off-grid then an inverter is likely a must if you want to power certain devices from your AC wiring system. Typical input and output voltages go from 12 volts of DC power supply to 110 volts of AC power.

If on the other hand, you plan to spend all your time in your rig hooked up to shore power, then such devices are probably not a necessity.

Important Factors in Choosing the Correct Inverter for Your RV

What Luxuries Can You Not Live Without?

A large part of choosing the right RV power inverter is going to depend on what you need it to power. RV appliances that use a heating element generally require a lot less power to start up than electronics that have a motor, which in turn use a lot less power than things like hairdryers and televisions. You must add together all the power ratings/watts of the electronics and appliances you’ll be powering and then get a van inverter with a power rating that matches or is higher. We explain more about watts in the next section.

Watts

As stated before, the total watts of your electronics need to be less than or equal to your inverter’s watts. However, there is a small catch with this. Most electronics that have motors have two different watts ratings. One rating, usually the higher one, is the starting watts. This is how many watts are required to get the appliance going. The second rating is the running watts, also called the rated watts. This is how much watts are needed to keep the electronics going after it’s been started up.

When adding up the watts of your electronics, use the starting watts. Otherwise, you may end up with an RV inverter charger that isn’t powerful enough to turn the electronics on.

Surge Rating

Just as some electronics have two watts ratings, so do RV power inverters. Don’t let all the different ratings confuse you. We’ll break this down.

Inverters have what is called continuous watts and surge watts. Continuous watts are much like the running watts of electronics, while surge watts are like starting watts of electronics. The difference is that surge watts are only useful over a certain length of time – usually a matter of seconds. This gives RV power inverters with smaller continuous watts ratings the ability to handle high levels of starting watts just long enough to get things going.

Having an RV inverter charger with a good surge watts rating can help you to save money because you won’t have to get the largest-rated RV power inverter to start electronics up. However, it may be beneficial for you to splurge on the higher-rated inverter if you plan to use all these electronics often.

Modified Sine Wave Inverter vs. Pure Sine Wave Inverter

These names may sound highly scientific, but they’re straight-forward.

Appliances run on AC power, which looks like a sine wave. Pure sine wave inverters convert the direct current power to a sine wave so that appliances can use it. Modified sine wave inverters also convert the DC power to a sine wave, but it’s more choppy and square-like instead of being a smooth curve. This causes appliances to have a lower performance then they would on a pure sine wave power inverter.

While certain smaller appliances such as griddles or microwaves can get by with a modified sine wave inverter, in the long run, these types of devices may damage them. Other types of appliances may not work at all on a modified sine wave inverter. For sensitive electronics such as cell phones or laptops, you should avoid a modified sine wave inverter altogether.

So, if modified sine wave inverters aren’t that great for appliances, why buy them at all? The answer to this question is simple: price. Modified sine wave devices tend to cost much less than PSW RV inverters. Our advice is to stick with a pure sine wave inverter to make sure that all your appliances stay safe. However, if you want to save a few bucks, stick with simple appliances and get the modified version.

Size and Weight

You probably already have a lot of camping gear, so the idea of having a gigantic, heavy inverter may be a turn-off. Unfortunately, the size (dimensions) and weight of an RV inverter is usually indicative of the amount of power it can convert. If you are only powering small appliances without motors, you can get away with a small, portable RV inverter. For everything else, you’ll have to scoot that gear over to make room for a big, heavy piece of equipment.

All the above information prepares you for shopping for an RV inverter. By arming yourself with the information we’ve given you, you can be sure to be able to pick the best power inverter for RV usage. We’ve kickstarted your shopping spree with nine of the best RV inverters on the market.

The Best RV Inverter Charger – The Best Pure Sine Wave Inverter Reviews

AIMS Power 3,000-Watt Pure Sine Inverter

Best Quality RV Inverter
