How Do Power Inverters Work?

An inverter is a device that converts low-frequency DC AC to standard frequency one. The principle of operation of this converter is quite simple: first, the device will work with the car’s battery, taking out the DC power.

Then, the AC will provide DC power. As a result, the device will change low-frequency DC to high-frequency AC – the common power source of most entertainment and home appliances today.

Why Should You Need Power Inverters for RV?

In the above, I mentioned the basic operating principle of the inverter. If you still find the above information too confusing and can’t see why you need to equip your RV with this device, some AC and DC information below will help you.

The RV’s electrical system operates on a 12V direct current (DC). Meanwhile, home appliances run on 110V, 120V, or higher alternating current (AC).

If you want to watch TV while driving, use your laptop, check the global positioning system (GPS) directions, and play mobile games, you will need a set of converted direct currents into standard alternating ones.

You also need an inverter on your RV if you want to turn your car into a backup source, helping to charge smart devices such as phones and laptops.

Thanks to this feature, the inverter has become a must-have device for long camping trips. Even this converter is highly applicable in emergencies.

For example, if extreme weather destroys the grid, the inverter for the RV will become the total supply, helping to operate the necessary electrical equipment.

Buying Guides

To be honest, I have made many mistakes in choosing an inverter for an RV. And as a result, my travels were uncomfortable, if not disastrous.

After a lot of mistakes, I have gathered the most useful experiences that can help your converter selection process go more smoothly.

Without letting you wait any longer, here are the factors you should consider to own the best power inverters for RV that will meet all your needs:

Inverter or Watts Capacity

The above factors will directly affect the inverter size that is best for you.

The inverter will have to meet two requirements for increased power and a normal degree in terms of capacity.

The capacity increase is related to the maximum amount of power that the inverter delivers in 15 minutes or less. Meanwhile, normal capacity is the steady power required by the inverter.

Another parameter also related to power is Average Power. To estimate the required battery capacity, you certainly will not be able to help but work with the above parameter.

Besides, when it comes to watts, to own the most optimal choice, you will need to focus on maximum and continuous loads.

You should note that, due to the conversion process in the car inverter, the actual available capacity is lower than the capacity stated on the product.

In some cases, you may not be able to charge the battery even if the inverter has enough capacity. So, you are better off choosing products with parameters related to Wattage or Watts that are slightly higher than your expectations.

Inverter Power Rating

Power is a parameter that helps determine the Inverter Power Rating.

Currently, you have a wide choice of inverter power ratings, from as low as 50 Watt to as high as 5,000 Watt.

Given such a wide range, it is common for many users to pay special attention to a product capable of delivering 5,000 watts or more. In reality, however, most owners fail to get the most out of these impressively capable inverters.

The most helpful advice for you when considering this criterion is to turn your attention to maximum sustained gain.

From the above parameters, you can find out the inverter’s ability to handle watts in a given time, thereby making choices that meet basic needs.

You should also note that not every manufacturer is honest with the published parameters. For various reasons, untested ratings may not reflect the actual capabilities of the inverter.

In addition, the actual capacity may be affected by the capacity needs of the equipment in the RV.

When evaluating this criterion, you should refer to the manufacturer’s published data and consider the reviews of previous users.

Owning a large amount of data showing the inverter’s processing ability in many cases will help you easily compare and make quick and accurate judgments about the product that best suits your needs.

Types

If you distinguish RV inverters based on the device waveforms used, you will currently have three main options, each of which has different advantages and disadvantages:

Pure Sine Wave

It is a fact that most of the power that comes from a generator is in this waveform. Therefore, it can be that Pure Sine Wave is the most popular type of RV inverter today.

It is impossible not to mention the compatibility with most RV devices of the inverter using Pure Sine Wave.

This type of wave also possesses a series of other commendable advantages, such as providing economic but effective power, allowing the maximum exploitation of the equipment’s capabilities.

With the above attractive advantages, devices using Pure Sine Wave have quite high prices, even 2 to 3 times higher than those using other waves.

Modified Sine Wave

The biggest advantage of the Modified Sine Wave inverter is that it is affordable but still does a pretty good job of supplying power to RV outlets and devices.

When choosing ones, you must anticipate some disadvantages that still exist of modified sine wave inverters, specifically:

Modified sine wave inverter models often provide inefficient power to devices. According to some tests, a modified sine wave inverter makes it possible for your RV refrigerator to consume 20% more power than a pure sine wave inverter.

This type of equipment can also reduce the brightness of the cabin lights, especially with fluorescent lights. Besides, noise is also one of the issues worth considering if you choose this type of inverter.

Square Wave

Similar to the modified sine wave inverter, Square Wave equipment is also quite cost-effective.

However, this waveform can only meet simple needs, while RV requires a complex power supply. Therefore, while it may be a good choice for the budget, it is quite difficult for you to use an RV with a square wave inverter.

Energy efficiency

Last but not least, in the selection process, you need to pay attention to the factor that greatly affects the entire system’s performance – energy efficiency.

An inverter with poor energy efficiency will not help too much in powering your appliances. Not only that, but substandard inverters can also be the leading cause of RV battery drain.

Meanwhile, equipment with high energy efficiency will provide stable, reliable power without too much impact on overall energy consumption.

The question is, what is the mark to identify a product with good energy efficiency?

Nowadays, you can easily find devices with up to 90% efficiency ratings. In reality, the above parameter can be much lower.

The reason lies in the conversion of AC to DC, which has converted a lot of energy. In addition, even the transmission of energy through the wire has a significant effect on the overall efficiency.

In this case, your only option is to find a converter with minimal loss. As you can see in the list above, some devices have a power loss of less than 10% – a pretty impressive number that any power inverters for RV users should aim for.

FAQs

With a series of suggestions and useful information above, you were confident of finding your own best power inverters for RV?

If you still have questions about several related issues, it’s time to consult a series of responses to the most frequently asked questions.

What size do you need for the camper?

The answer depends on how you use the inverter. For easy sizing, you should calculate the RV’s minimum capacity requirement.

The calculations are pretty simple: first, determine the wattage of the RV’s largest appliances, then add up the wattage needed to run those large appliances.

The result is the minimum power threshold. The RV inverter you choose needs to provide a higher power level than the minimum you specified above.

How to set up an RV inverter?

There are quite a few ways for you to install an RV inverter. In the framework of the article, I will introduce you to the four most common setup methods:

  • Connect the RV inverter directly to the AC distribution box

To set up this way, you will need to prepare a toggle switch capable of auto-selecting the power source.

The cost to own the switch is not small. Also, another disadvantage of this method is that you need to use a decoupled distribution board not to power the converter from the inverter.

  • Using an extension cord

This method is quite quick and simple when all you need to do is use the extension cord to connect the inverter to the devices you want to use.

  • Use sockets

With this method, you need to set up an external socket first. You will then connect the output of the inverter to the upper outlet. During use, to power up, you just unplug the RV from the power source and connect it to the outlet you set up earlier.

  • Remote switch

Some manufacturers will add a remote control feature.

For connection, a telephone cable is one of the most effective tools. If the line doesn’t work, you’ll probably need to consider signing up for wire gauges and lengths. Because a cable of the wrong size can cause too much resistance, making it difficult to function as it should.

Modified vs. pure sine wave, Which is better?

As mentioned in the previous section, it is clear that pure sine wave inverters possess many advantages over other waveform-using devices.

Specifically, the pure sine wave inverter can provide economical but efficient power, allowing the maximum exploitation of the equipment’s capabilities.

However, pure sine waves cannot continue to hold the upper hand in terms of cost. The price can be 2 or even 3 times higher than the Modified sine wave. It is clear that buyers will have to consider a lot when investing in equipment using this special wave.

What are the benefits of an RV converter?

RV converters offer quite a few benefits.

  • The first is to provide an efficient, reliable power source for most appliances and gadgets.
  • Second, the RV converter is the perfect alternative to a gasoline-powered generator that doesn’t require you to stock up on fuel.
  • Third, one of the outstanding advantages of the best RV inverter converter compared to the main generator is the relatively low noise.

You will appreciate this advantage when carrying an RV converter instead of a generator when camping. In contrast to noisy gasoline-powered equipment, the quietness of the power inverter for the camper certainly won’t ruin your entertainment moments.

How big of an inverter do I need for an RV?

The only advice is to specify your needs and usage of the device.

For example, if you want a device directly into a 12V outlet, you will need small, highly portable inverters.

Meanwhile, if you are looking for a product that can accompany and support the camping experience in remote areas, an inverter with a large enough 120V battery will be ideal.

What will a 3000-watt inverter run?

A 3000-watt inverter generator can do more than you think. These devices can confidently power most items in your daily life, such as water heaters, microwave ovens, and even air conditioners.

In addition, 3,000 watts is also an ideal parameter to become a backup source for camping trips and caravans.

How much is an RV inverter?

On average, a motorhome inverter between 2,000 watts and 3,000 watts will cost between $150 and $300.

Conclusion

The best power inverters for RV offer more benefits than you think. Not only simply providing uninterrupted power no matter where your car goes, but it also plays an important role in protecting the electrical system, converting direct current into alternating current.

With the above information and top picks, you can easily find a product that possesses all the above advantages. Hopefully, your final choice will meet your personal use needs, making your road adventure more enjoyable and comfortable.
