Expect to have an easier time formulating a wise buying decision if you scrutinize the following factors carefully:

Power or watts – You will find this factor useful in determining the specific size of RV inverter that you need. Note that an RV inverter has to meet two requirements or needs in terms of power – the first is the surge or peak power and the other one is the usual or typical power.

Surge refers to the maximum amount of power supplied by the inverter, often for a short period (up to a max of fifteen minutes). Some onboard appliances, especially those that use electric motor need an inverter with a higher startup surge.

The usual or typical power, on the other hand, refers to the power that the inverter needs to supply steadily. Otherwise referred to as the continuous rating, the usual or typical power is often lower than the surge.

In selecting the best inverter for your recreational vehicle, it is important to get an idea about average power. This one is significantly lower than surge or typical power. You can use the information regarding average power at the time you need to estimate the required battery capacity.

One thing to remember when taking a look on the inverter’s power or watts is that sizing the inverter should be based on the typical continuous load and max peak load.

Power Rating – Picking a good RV inverter is also possible if you check its power rating. Remember that inverters are available in various size ratings ranging from 50 to 50,000 watts. However, take note that those units that provide more than 11,000 are not used by potential users that often.

One of the most important things you have to know about your chosen inverter is its max surge. You also need to figure out how long it can maintain such surge. An inverter’s surge rating is actually specified at a certain number of watts for several seconds.

What this means is that the unit is capable of handling the specified watts for the mentioned period of time. Such rating or capacity differs significantly from one inverter to another so you really have to scrutinize each type and brand to find out which one can meet what you need.

Types – You also have to understand the different types of RV inverters that are available today. Be aware of the pros and cons of each one as this can help you spot the perfect fit. You will get to know more about different RV inverter types as you go on reading this article.

Energy Efficiency – The energy efficiency of the inverter should also be a deciding factor during the selection process. It should be energy-efficient in the sense that it will not cause a significant increase in your energy consumption. However, this should not also cause the loss of energy and power.

The length of time your equipment can operate without AC power – Another crucial factor is how long it often takes for your onboard equipment to operate in case there is no AC power.

You can choose small, in-vehicle RV inverters when planning to run equipment at an indefinite period while ensuring that the battery power is available and the RV’s engine is running. In case you need a good supply of power for an extended period, then it is necessary to invest in large inverters.

Input and output voltage – Determine the unit’s input and output voltage, too, as it helps you figure out if it is indeed a good fit for your RV. You need to choose an RV inverter, which is compatible with the battery’s voltage that supplies power to it (input voltage or DC).

If you make use of a 12V battery, for instance, then it would be ideal to pick a 12V DC RV inverter. One more thing to take note of is the output voltage or AC. Note that electronic devices in Canada, Mexico, US, and some parts of Latin America utilize 120V AC power. Other devices available in other parts utilize 220V to 250V AC power.

Other Important Factors to Consider


What is an RV Inverter

An inverter designed for your recreational vehicle refers to a device with the main purpose of converting low-voltage direct current (DC) power to the standard alternating current (AC) power.

Once installed, you will realize how useful this device is in operating electrical equipment and other onboard appliances with the aid of the power that renewable energy sources, like wind turbines or solar panels, or the battery of your boat, car, or truck can produce.

In other words, the inverter serves as a reliable source of power for the equipment and appliances in your boat, work truck, car, and RV. You can also use it in protecting your belongings in case of a power outage. It is because it can supply an emergency backup power to certain equipment, like freezers, refrigerators, etc.

Types of RV Inverters

Choosing the most appropriate inverter for your vehicle would not be possible if you do not know anything about its different types. To help you become an informed buyer, here are some details about different inverter types:

Sine Wave – One popular type of RV inverter is the sine wave. This type refers to what you usually receive from generators and local utility companies. It is mainly because you can generate it by rotating air conditioning machinery. Also, sine waves are known to be naturally produced through such rotation.

One advantage of this type of RV inverter is that all appliances and equipment that are currently on sale in the market are suitable for it. With that in mind, you have a guarantee that the equipment and appliances in your RV will operate based on their full specifications.

Also, take note that certain appliances, like microwave ovens and motors, are only capable of producing their full output when you use sine wave power. Other appliances, like light dimmers, bread makers, and battery chargers also need this type to operate.

The only problem with this type of inverter is that it is quite expensive. In fact, its price is around two to three times higher than the other types but it is actually worth it.

Modified Sine Wave – This type boasts of a waveform. What is good about this inverter is that it works fine with the majority of equipment. However, you should remember that it also causes reduced power or efficiency in the mentioned equipment.

Also, motors, like the ones used in refrigerators, fans, and pumps, will consume more power from the modified sine wave inverter because of its lower efficiency. In most cases, they are capable of consuming around twenty percent more power.

In case there are fluorescent lights in your vehicle, then you can’t expect them to operate as brightly as when you are using other types of inverters. There are also instances when they will produce some humming sounds or buzz.

The modified sine wave inverter also tends to produce more noise than the pure sine wave. If you do not care too much about the mentioned issues, though, this inverter will still work in your favor. You will also be most likely pleased to know that it is cheaper than the pure sine wave.

Square Wave – This type is the cheapest among the most popular forms of inverters. It is capable of operating simple things without issues. These include tools that feature universal motors. However, its capability is limited to that. That is why you can rarely see square wave inverters at present.

Benefits of an RV Inverter

Your RV inverter functions by taking 12V DC power for the batteries of your RV and changing it electronically into 120V AC. Keep in mind that your RV batteries are designed in such a way that they can supply power in DC (direct current) running at a low voltage.

If you are an RV enthusiast for quite some time now, then you have most likely experienced that scenario wherein you are in need of an inverter. It could be during that time when you decided to go dry camping without any access to an electricity.

So what are the positive things that you can get from an RV inverter? Here are just some benefits supplied by the inverter:

Highly Efficient – Aside from inverters, you can also make use of gas-powered inverters as a means of supplying you with the power needed to operate your onboard devices. However, these generators can’t provide the same level of efficiency provided by reputable power companies to your home.

If you decide to invest in a pure sine wave power inverter then rest assured that it is capable of supplying you with such highly efficient power. The majority of devices and appliances can operate using pure sine wave power. While you can also use the modified sine wave type, it tends to run hotter than what is normal.

It also tends to have a lower efficiency than the pure sine wave. This means that if you wish to enjoy the benefits provided by an inverter as far as energy efficiency is concerned then it would be best to go for the pure sine wave type.

Does not require fuel/gasoline – The major function of a power inverter is to convert battery power, which means that it does not require you to use gasoline. This means less hassle on your part since you no longer need to store enough supply of gasoline just so you can get power all the time.

Remember that you can only store gasoline for approximately one month. With that in mind, using generators instead of inverters requires you to store fresh gasoline all the time, so you will not end up having to run to gas stations in case of power outages.

If you do not want to deal with the hassle of storing gasoline, then investing in an RV inverter is the best decision you can make.

Does not produce noise – It is no longer a secret that generators produce a lot of noise, especially if you go for the cheapest models. RV inverters are popular for their ability to operate without noise.

They function silently. This is beneficial, especially if you need to use power supply in a campsite. You do not want to use a noisy generator, which can be a nuisance to those around you, do you?

In determining the ideal RV inverter size for your needs, you have to remember that these units are rated in watts. You can also find them in various sizes and ranges of power. They can run from 75 to 3,000 watts.

If you do most of your camping at the campgrounds where there is an abundant supply of electricity, then an inverter may be unnecessary. However, you might find your camping experience more enjoyable by having an inverter and batteries that can meet your 120V requirements.

In selecting the right size of the inverter, it is also a must to assess its output capacity. The best choice is that which can operate on the loads placed into it. In this case, be aware that there are two capacity ratings available for the inverter – the surge capacity and the continuous output rating.

Aside from that, be aware that you can now find inverters in small and portable sizes. These are the ones that you can directly plug into a 12V outlet or cigarette lighter, supplying power or electricity to the whole electrical system of your vehicle. What is good about these units is that you can permanently install them in your vehicle.

You can also go for the inverter or chargers found in the majority of recreational vehicles today. They are not only inverters but also serve as transfer switch and battery charger in one. The units serve as battery chargers each time you plug them into a source of electricity or when you are using a generator.

What’s good about these inverters is that they are also capable of storing DC battery power without any available generator power or source of electricity. They can automatically transfer the power into the battery charger.

How to install an RV inverter?

Installing an RV inverter is something that you can do alone. If you use a small inverter – one which operates at approximately 75 watts, then you can just conveniently plug it into an outlet for a cigarette lighter. Inverters that are larger than that, however, will need to be directly wired to your batteries.

In case you need to install the unit using the latter method then you have to do it really close to the batteries to minimize the risk of losing voltage. It would be best to check the manual, too, as it will give you a suggestion regarding the ideal wire size. Go for the size that is recommended in the manual or one that is larger.

As for the actual installation, the most efficient but expensive way to do it is by connecting the unit directly into the AC distribution box of your RV. You can connect it via the transfer switch.

Remember that the kind of switch will differ depending on the inverter’s power and whether or not you also have an RV generator. The transfer switch will choose shore power provided it is available.

In the absence of the shore power, it will choose the power of the inverter. In case you prefer to choose this route in terms of installation, powering up your converter from the RV inverter should be prevented. One way to avoid that is to utilize a split distribution panel.

Another method of installing the RV inverter is by using an extension cord. All you have to do is to run it from the RV inverter to any device you intend to power. The only downside to this method is that it is a bit troublesome and tiring to plug and unplug various devices to the extension.

How to use an RV inverter?

RV inverters come in different sizes and are measured by watts. The power you need to use will be fully dependent on the specific equipment you choose and plan to use. The majority of RV inverters, specifically those that run lower than 300 watts, can be plugged to your vehicle’s battery with the aid of a DC port found on that dash.

If available, you can use the cables provided by your chosen model by connecting them together with the battery directly. What is good about the inverter is that it comes with at least one basic socket that you can use in charging portable devices, like DVD or video player, laptop, and TV.

An RV inverter, which transfers DC current into AC is ideal if you wish to go on picnics specifically on areas without electricity. To use the inverter wisely, it is also advisable to run it with a fully charged battery. The battery should be in excellent condition, too, as a weak one might drain fast.

If that happens then you will most likely be in passive scenarios. This is the main reason why you have to examine the battery prior to operating the inverter. Another thing to keep in mind when using the power inverter is to ensure that the wires in your car work compatibly with the current.

Check their compatibility prior to plugging the unit into a lighter. Moreover, there should be enough and suitable ventilation for the RV inverter. Note that regardless of the size of the inverter, it will still produce heat.

With that in mind, find out if there are available fans within an inverter, which operates at least a hundred watts. Ensure to use it in an area that has good ventilation, too.

When should you turn your RV inverter on/off?

Using your RV inverter correctly also requires you to understand the perfect time to turn your unit on or off. In determining when you should turn on your RV inverter, it would be best to answer the question of whether or not your vehicle comes with a charger or an inverter.

If it features such then each time there is an available source of AC power, the charger will be capable of charging the batteries completely and maintaining them. Such is beneficial because the batteries that are considered as the source of power needed by an inverter have to stay at a full charge or close to it.

With that, the batteries will be capable of supplying a reasonably long power in the absence of other AC power source. Another thing you have to keep in mind when determining the right time to turn your RV inverter on/off is that the power needed in running the unit is usually around 8 to 10 percent higher than a load of power required in running your appliances.

This is mainly because most modern and high-quality inverters are now highly efficient. In fact, you can find inverters that are around 90 to 92 percent efficient. Also, take note that your inverter will most likely consume power from the batteries in case it is unused but stays turned on.

The power it draws differs from .02 amps to 2 amps. The figure will fully depend on your actual inverter as well as how its standby systems are designed. In case you keep your unit turned on without connecting any load then it is possible for your batteries to draw around 1 amp every hour on average – a total of around 24 amps daily.

To prevent your unit from drawing too much power, it would be best to turn it off if you do not need it to prevent the battery from draining to zero. The good news is that this is a convenient process as some inverters today have optional or standard remote controls to turn them on or off.

What happens when an RV inverter goes bad?

An RV inverter, which goes bad, will cease to function properly. This leads to power interruptions, the failure or the breakdown of the unit, and huge financial losses, especially if it starts drawing too much power.

To deal with the issues that might result from a malfunctioning RV inverter, you have to be more aware of its possible causes. One possible cause of a malfunctioning RV inverter is its improper installation.

Other possible causes include failure to stick to the recommendations and advice indicated in the manual and choosing the wrong type of cable, in line fuses, or gauges. You have to figure out the exact cause, so you will know exactly how to prevent your unit from malfunctioning.

Will an inverter run an RV air conditioner?

Yes, an RV air conditioner can run on an inverter. However, air conditioners are power-hungry appliances. They require four to eight times more electricity to start various components, such as the compressors and condensers.

For example, a 120-volt, 12-amp RV AC might need 48 amps during startup and 12 amps when running. That is why one needs a soft-start kit together with the inverter.

Inverters convert 12-volt battery power into 120-volt usable electricity, ten times the battery’s capacity. Hence, if the RV AC requires 12 amps when running, the battery must supply at least 120 amps. A 600Ah battery will only provide about 300 amps if one observes the 50% battery discharge recommendation. The RV AC will only run for about 2.5 hours.

Most RV ACs require 3,000 watts of power or more. It would be best to get an inverter with a higher wattage rating (i.e., 3,500 or 4,000 watts) than the AC to avoid straining the inverter.

One can also use an RV inverter size calculator to make the determination more straightforward.

Possible Issues of your RV Inverter

When maintaining the excellent condition of your RV inverter, it is advisable to constantly check it for the presence of the following issues. It is because these issues are indications that your unit is on the verge of partially or fully malfunctioning.

Wear on the capacitor – One reason why your RV inverter malfunctions is its capacitor’s electromechanical wear. Remember that your inverter fully depends on its capacitors as a means of constantly supplying an excellent power output regardless of the current’s level.

The problem is that these capacitors come with a limited lifespan. They also tend to age quicker when compared to dry parts. Such might cause the failure of the inverter’s main functioning.

Also, these capacitors are known to be temperature-sensitive so avoid going beyond or lower than the required operating temperature. You can prevent capacitor wear by scheduling regular maintenance. Replacing them can also prevent the majority of problems triggered by possible wear and tear.

Overuse – Overusing your inverter might also cause problems to it in the long run. This is the main reason why you should avoid utilizing it over its operating limit. Note that constantly overusing it might cause its bridge failure.

Avoid using the inverter at a higher than the operating limit’s rating as doing otherwise might also lead to its failure and lower lifespan. To prevent issues associated with overuse, make it a point to check whether you are running/operating the inverters correctly.

Ultrasonic vibrations – Another issue to avoid is ultrasonic vibration as it can put a lot of mechanical stress into the unit. This issue might trigger friction that can increase the unwanted heat that your unit generates, causing damages to its components.

To avoid this, do not overlook regular maintenance. Remember that electrical connections have the tendency of corroding or loosening. Do not neglect any sign that it is experiencing wear and tear, so you won’t have to deal with ultrasonic vibrations.

Final Words

Choosing the best RV inverter is the key to having a continuous supply of power in your recreational vehicle regardless of where you decide to go. However, make it a point to do a comprehensive comparison of the different RV inverters. That way, you can choose one, which is not only fully functional but is also easy to use.

Also, note that you will need a portable and compact RV inverter, one that you can easily fit in your vehicle. It should also be reliable that you can constantly put your mind at ease, knowing that there is a tool that you can use to ensure that you will never run out of power.
