Written by Liam Jaxon / Fact-checked by David Rowan

To live a civilized life in the middle of nowhere, only a marine or RV battery is not enough. By pairing the battery with a marine inverter, you can ensure all your AC gadgets and appliances are running nice and smooth. When it comes to using an inverter for boats, you have to be a little bit more careful.

The reason is, out in the water, you are all alone with just your boat. You can’t risk your life and money by purchasing a poor inverter that can set the boat on fire by overheating or fry your appliance by overcharging.

power inverters for boat – choosing guide & recommendations

Don’t panic about what I stated lately. I am here to save your back and budget. On my list, you will find the best inverter you own in your budget. Also, you can get enlightened by reading the tips that are useful to choose the correct inverter for your use.

Use of Inverter

In a simple sentence, I can say, inverters change the DC current to AC current. In a broader sense, it explains that the devices we use on a daily basis like TV, refrigerator, mobile phones, etc all run on AC power.

In an off-grid situation, we have to rely on DC power or a generator. Currently, the major DC power source is marine batteries of different kinds. These are compact, waterproof, and portable. These are the reasons people are picking up marine power inverters and batteries over generators nowadays for remote use. 

An inverter uses the battery power and transforms it into an AC current. So that you can use all the gadgets on the planet you want. It is also quiet, does not require fuel to run as generators do, and super light, and easy to operate. So, a unit of a marine battery and marine power inverter takes over the big bulky generator for better usability.

How to Choose Power Inverters for Boat

Nonstop Wattage

Ostensibly the main thing to think about while purchasing a power inverter. At the point when you know the nonstop wattage, you know the number of apparatuses the inverter can control. 

For example, assuming that you have a 2000-watt inverter, you realize you can deal with an 800-watt microwave. One thing to recall is that most inverters can not offer you 100 percent effectiveness.

 Assuming that it says 2,000 watts, anticipate that it should maximize at 1800 watts. Most inverters can pull around 90% productivity. As a sanity check, plan for that as your pattern.


Inverters are sold as either altered or unadulterated sine waveforms. Altered sine wave inverters are more affordable. These are more effective power sources. They can make more power and move more power. On the off chance that you are utilizing more modest gadgets, an adjusted inverter will likely do the occupation for you.

In the event that you’re running some significant gadgets, you’ll need an unadulterated sine wave inverter. These inverters can deal with enormous apparatuses. Consider things like fridges and ovens.


Of course, you must have some idea about what kind of appliances you are using in your boat or RV. Buy an inverter with a bigger capacity. It will help in the long term and you will not face a low voltage problem while using all the gadgets in the first hour of the day.


It is true that we all want to save space when we are on the go either in an RV, camping, or a yacht. It must take into consideration that, the more powerful and higher capacity the inverter is, the bigger the size will be. Sometimes you may have to compromise with the capacity to make room for a compact and tiny inverter in your beloved yacht.

Protective Features

This is the second most important thing you need to notice about a power inverter. It determines how long this inverter will last. Not only that but the devices you will be powering up using the inverter also can get damaged if the inverter itself is not protected enough. 

Considering that, we have included all the inverters with impressive protective features in this list. All of those are overheated and overload protected. The inverters with auto start fans are better as the fan starts when the machine heats up. This saves from unnecessary usage of power. 


More outlets are better for using the inverter during camping or in an RV. for using in a boat, I prefer using a multiplug instead. It helps to keep the tiny space less cluttered and keeps the inverter undisturbed. 

Additional Features

To use inverters occasionally, only basic features like LED charge indicator, etc are enough. For regular or daily usage, look for an inverter with more enhanced features like a remote control with a long cord, a digital display, and so on. It makes the experience of using a marine power inverter a lot more comfortable.

FAQs By People

Where Should the Inverter Be Installed?

An overall suggestion is to design the inverter as close to the battery banks as could be expected. The distance ought to be under 10ft, to stay away from pointless power misfortune and voltage drops, as well as to lessen the possibilities of a risk happening. Where you store it ought to be dry and ventilated, and this goes for putting away the battery as well.

Where Would It Be a Good Idea For Me to Put My Inverter?

Ensure the inverter isn’t set close to any unsafe or combustible materials. It should likewise not be presented to dampness or water. The area you select should be away from direct daylight and is a dry region. It should be set in a space that has free space around it.

What Do Power Inverters Do and How?

The power inverters utilize  12V power from marine batteries to create an explanation of it to 120V AC which you can utilize to fuel locally available devices as you go to the ocean. Since it utilizes batteries to do this, it’s really smart to have a separate battery for this if you don’t have any kind of reinforcement structure.

How Does a Power Inverter Function?

A vehicle power inverter is an electrical transformer that takes the 12-volt direct flow (DC) and changes it to a 120-volt substituting flow (AC). That permits you to run little electrical gadgets that you typically plug into a divider repository.


I know, even if you know which inverter is the best, you can’t just order it right there and then. You have to consider a lot of things before buying them. Not to mention the things you need to compromise while using it. However, it is compulsory to ensure survival in challenging environments.

So, I would recommend not to compromise the quality of the inverter you are ordering in the end even if you have to break the bank to purchase a quality one.
