If you’re ever in a situation and lose power from all of your appliances, a spare inverter can help restore power. All you have to do is hook it up to your RV battery, depending on the size this can also be done via your dashboard. Thankfully, there is a long list of inverters on the market at the moment, and we will help you find the best ones for your RV. This is quite daunting at first when you don’t understand the jargon. However, there is a helpful Q&A section near the end also, and in-depth descriptions.

Aspects to Consider When Buying an RV Inverter
There are a few aspects to keep in mind when searching for your next investment, such as the watts it can release, power rating, voltage input, and output as well as the energy efficiency.
This part is essential in deciding what size of inverter you’ll need for your RV. It has to meet surge power, and usual power requirements as many appliances within your RV can only work with a high surge power. This surge power is the maximum level in which the inverter operates. The usual power is just the amount that will be provided continuously to your appliances after the surge is over.
Another consideration to make that’s similar to the previous aspect. You can find models that provide power between 50 watts and 50,000 watts. Most RV owners won’t need more than 11,000 watts for their appliances.
Input & Output Voltage
Understanding your RV’s capabilities is another way to find the perfect choice, this means knowing the input and output voltage. For example, if you have a 12V battery, you will be able to buy a 120V inverter.
Energy efficiency can save you a lot of time, effort and money, but only when you find the right product. You should always find the most efficient inverter which can still provide the same amount of power to your appliances.
Review of the Best RV Inverters
This review will be as in-depth as possible and hopefully will explain things in a more comfortable way too many jargon-filled product descriptions and reviews out there.
This inverter should be regarded as the best currently on the market. It has 2000 Watt continuous power capability and can reach 4000 Watt’s of sheer surge power. This product also has two alternate current power outlets with one quality USB port for your mobile devices. The remote control feature allows you to turn the inverter on/off with ease from almost anywhere within your RV.
To prevent any overheating and shortages, it has an integrated cooling fan. The soft start technology, input, and output design allow for great safety features that protect against multiple hazards such as over-voltage, overload, over-current, under-voltage. The manufacturers offer a great 18-month warranty just in case the durable aluminum casing doesn’t protect against any accidents.
It offers the best features currently on the market, the multiple safety features make this safe to use in any environment. This model produces up to 4000 Watts which can power anything from a microwave to a radiator. The remote control function is something rare and unique to only a few models out there.
The only downsides to using this product are that it doesn’t have as many power outlets as others, the use of a modified sine wave also indicates it might not be as efficient as a regular sine wave inverter. The product description they provide states it runs with 90% efficiency.
Best RV Inverter Charger:
CTEK (56-864) MUS4.3 12 Volt Battery Charger
This charger is one of the best currently on the market. This product will be able to restore any battery to full charge once hooked up, helping you get the best out of both your battery and inverter. The charger has excellent protection against water, dust and the most any element can throw at it.

Types of RV Inverters
You should understand the different types of options as they can provide a whole host of advantages and disadvantages. Some are more expensive because they are incredibly efficient, some are cheap but soak up power like a dry rag on water, and other’s are just cheap and don’t work at all.
Modified Sine Wave
This option can work effectively with most household appliances. However, this method consumes more energy from your battery and reduces power from the devices. Appliances that operate with an electric motor such as a refrigerator or air conditioner won’t work to their full ability. The only reason most people buy these products is that they’re cheap.
One of the most common choices out of any type of Inverter. This unit generates power by rotating air conditioning machinery. It is compatible with most appliances which makes it the number one choice for RV owners. Devices running on this power will work to their maximum capabilities unlike those using a modified sine wave. The only downside to these is that they’re more expensive.
This one is known mainly for its low cost. This can power simple appliances and tools with universal motors, the downside is that it’s limited in its ability to power a long list of appliances.
Finding the right choice can be a daunting task when you don’t understand the jargon or technical aspect behind it all. All you need to remember is that most RV manuals will provide you with all the information you need to find a compatible inverter.
You might need to fork out a few extra bucks to get the most efficient model, or you could be happy with your appliances working a little slower to save on costs. Whatever choice you make, hopefully, this review makes it a lot easier for you.
People Also Ask
This section is to help anyone understand the jargon and any in detail parts of the buying process or how these products work. They can be quite complicated, and hopefully, this part can help ease your mind or answer any questions.
What Does An Inverter Do in an RV?
An inverter is a device that takes Direct Current (DC) from your RV battery and turns it into Alternating Current (AC) which can then be used to power appliances such as microwaves, ovens and air conditioners. Multiple types have different limitations.
Do You Really Need a Pure Sine Wave Inverter?
You don’t need one. However, other types of inverter aren’t as powerful or efficient. If you don’t mind sacrificing power to save some money, go ahead and by a modified sine wave Inverter. Keep in mind that square wave inverters are the least powerful and are best used for tools and small appliances.
What Can I Run on a Modified Sine Wave Inverter?
You can run most household appliances like refrigerators, ovens and air conditioners. However, these products won’t work to their optimal performance as this type doesn’t consume your RV battery power efficiently. This problem is mainly for any electric motor appliances.
What Size of Inverter Do I Need for my RV?
The size of your inverter depends on the capabilities of your RV battery, you should check the input and output for the battery. For example, a 12V battery can churn out 120V of power. If you can match them effectively, you will get the maximum the Inverter can give.
RV Inverter vs. Converter - What’s the Difference?
Inverters take the direct current and turn it into alternating current usually from a battery. Whereas, Converters take the alternating current from an electrical device and convert it into direct current.
How Long Will a Battery Last With an Inverter?
There are a few variables to consider before hooking straight up to your RV battery, you would need to know how many amps per hour your battery gives off. For example, a 90-hour amp rating (400 Watts) can survive up to two hours. If you have a deep-cycle battery, you would be able to use all of the battery and then recharge for further use. This would be beneficial as you don’t want to be stranded with no electricity and power.
