Best RV Inverter

BCI 3,000-Watt Pure Sine Wave Inverter

BCI 3000 Watt Pure Sine Wave Inverter / 12VDC to 110VAC

Out of our list of nine inverters, we chose the BCI 3,000-Watt Pure Sine Wave as best RV inverter. It has great versatility, and with an attractive price tag, this campervan inverter has a lot to offer!

This is one of the few options on our list that can even be used in freezing temperatures. That alone sets it apart from competitors. It’s also safe for your cellphones, laptops, and other sensitive devices. Whilst 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, it is lightweight and small measuring 16.9 x 7.1 x 5.5 inches and weighing under 15 pounds. Most 12v inverters that perform at this caliber are bulky and heavy, so we appreciate the ease of use with this model.

In an ideal world we would have liked the warranty to be longer than one year, but this little issue is far out-shined by the array of features on offer coupled with the fact that this product will last a long time if it is taken care of

How to Choose a Great RV Inverter

If you’re reading this article, you may already know what an inverter is, but in case you don’t, here is the basic lowdown. 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 your 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 RV inverter at some point. This can be avoided if you have a generator that has it already built-in. 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 your RV power inverter needs to be.

Now that you know what an inverter does, let’s get to what you need to know to choose the best power inverter for RV or caravan use.

What Does an RV Inverter Do & Why Do You Need One?

An Inverter for your motorhome or camper is a device that will transform DC power from a power source 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. Typically input and output voltage will go from 12 volts of DC power supply to an AC voltage of 110 volts.

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 a hairdryer or television. 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 electronic devices 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 a model that isn’t powerful enough to turn the electronics on.

Surge Rating

Just as some electronics have two watts ratings, so do RV inverters. This can get confusing so let’s 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 a good surge watts rating can help you to save money because you won’t have to get the largest-rated model to start electronics up. However, it may be beneficial for you to splurge on a higher-rated model if you plan to use all these electronics often.

Modified Sine Wave Inverters vs. Pure Sine Wave Inverters

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 power inverters also convert the DC power to a sine wave, but it’s more choppy and has a square wave output instead of being a smooth curve. This causes appliances and devices to have a lower performance than they would on pure sine wave power inverters

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

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

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 r 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 model. For everything else, you’ll have to scoot that gear over to make room for a big, heavy piece of equipment.

The above advice should prepare 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 out the best power inverter for your RV needs. We’ve kickstarted your shopping spree with nine of the best RV inverters on the market today.

We’ll start this list off with an industrial-grade pure sine power inverter. The AIMS is one of the top RV inverters for being extraordinarily well-designed and manufactured. It has a surge capacity of an incredible 9,000 watts for up to 20 seconds. That’s a 300% surge, which is rare for a commercial model.

This option has a lot of features, but one of the most impressive is the built-in battery RV inverter charger that charges at 100 amps. It’s adjustable from 0 percent to 100 percent so you can have more control over how fast and how much the battery is charged. This comes in handy if you happen to have a small battery.

Unfortunately, it only has two 110-volt standard power outlets, which, for the price is disappointing. However, we are so impressed with the overall quality that we can overlook this (it’s nothing that a good power strip can’t fix). The AIMS 3,000-watts is 16.48 x 8.74 x 7.10 inches and weighs 64 pounds. It’s a fair-sized inverter with a lot of high-quality tech packed into a little box.

  • PROs

Another attractive feature of this model is the number of automatic functions that it performs. When AC power is available, it automatically charges batteries. It also automatically passes the power from the AC power source directly to the appliances or electronics, saving the battery power for backup. When the alternating current power is disrupted, it automatically switches back to inverting direct current battery power.

This was designed for heavy-duty use with little to no physical monitoring so you can spend your time focusing on what matters most. It’s truly a “set it and forget it” piece of equipment. This is not a portable model. It will have to be hardwired into your RV, and you’ll need to purchase the basic remote panel separately.

This model weighs 45 pounds and measures 7.9 x 11.5 x 13.2”.

  • PROs

    • Automatic functions are very convenient
    • Has automatic battery temperature sensing
    • Power-sharing prevents tripping of the internal circuit breaker
  • CONs

    • Troubleshooting LED light is complicated to figure out
    • It’s a modified sine wave inverter

Bottom-Line: This is an excellent model with an incredible surge watt rating that is suitable for heavy-duty and even professional-grade appliances.

Peak PKC0AW 3,000-Watt

Best Value

PEAK Mobile Power Outlet, 3000 Watt

We included this option on the list because it’s great value. While we won’t go so far as to call it a budget option, it is on the lower end of the RV inverter price spectrum, and it does have many attractive features. One of the main things we like about it is the fact that it has four standard 110-volt sockets plus one USB port. This allows you to plug up several appliances or electronics without needing an extension cord or power strip. Many of the premium inverters for RVs on this list don’t even have this many options. Unfortunately, it’s a modified sine wave inverter, so you can’t charge or power sensitive electronics from the USB port.

The Peak PKC0AW can handle up to 3,000 continuous watts and 6,000 watts of surge power. This is average as far as other models on the list; however, we will admit that this option may not be able to handle 3,000 continuous watts. Therefore, you may be better off keeping your continuous watts at 2,000 or lower and in doing so you are sure to have a great product without spending a fortune. The Peak PKC0AW is very lightweight and compact measuring in at 20.8 x 9.8 x 5.9 inches and weighing a little over 17 pounds. This makes it very easy to work with.

  • PROs

    • Has a wired remote on/off switch
    • Comes with everything you need to hardwire it to your RV
    • Safety features such as overload protection
  • CONs

    • Inefficient with power conversion
    • Can easily overheat

Bottom-Line: If you need an RV inverter for simple things and are not concerned about the specs and details, the Peak PKC0AW is a decent choice.
