The purpose of a marine inverter for your boat is to supply much-needed power for your electrical appliances.
Inverters simply convert direct current to alternating current by increasing the voltage.
The best marine inverter is the Xantrex 806-1210 PROwatt that has a built-in digital display for DC volts and output power as well as other clever features.
Compared to fuel-powered generators, the marine inverter offers silent, easy to install and maintenance-free power for all your electrical appliances on the boat.

The conversion of direct current to alternating current has a varying amount of efficiency from brand to brand.
The average efficiency of most marine inverters is approximately 90% and its important that you look for these ratings.
Ease of use is important as many of the highly-rated examples include remote switches, heavy-duty terminals, live data output and more.
On top of performance, safety needs are paramount and surge protection, as well as other features, are critical.
Below is a list of the best marine inverters for boats that offers efficient power for all your electrical appliances.
Xantrex 806-1210 PROwatt Inverter
The Xantrex is a popular marine inverter that includes a range of outputs including a useful USB port for additional charging.
The built-in display shows live DC Volts and output power values that can be used for safety checks.
Other features of the Xantrex 806-1210 PROwatt include a 12VDC input, GCFI plug, LED Display, optional remote and more.
The maximum output of this inverter is 1,000 watts, which is ideal for the majority of boating electrical appliances.
For an improved connection to the battery, included are heavy-duty terminals that connect without any trouble.
Many cheap alternatives can have poorly made terminals that can cause havoc with unreliable power.
Overall, the 806-1210 PROwatt by Xantrex is the best marine inverter for the money, which combines performance and ease of use for a perfect package.
ProMariner 02012 True Power Inverter
The ProMariner 02012 is a premium inverter that outputs 2,000 watts.
There is no escaping the fact that it is very expensive but the ProMariner brand is known for producing excellent marine products such as top-rated marine battery chargers.
With this marine inverter charger, you are able to choose between 7 three-stage charging profiles for safe battery charging.
This device also features a 2.8x surge rating with 1.0 power factor and an instant AC transfer switch.
The 02012 is the upgraded model to the QS series and the main difference is Pure Sine Wave AC output.
This is a similar quality of AC power that you will receive at home for all the powerful electrical appliances.
The inflated price is due to the fact that it is a powerful high-quality inverter as well as a marine battery charger.
This is highly desirable and the ProMariner True Power is the best marine inverter charger you can buy but only if you can afford it.
Go Power! GP-3000HD Marine Inverter
The Go Power is the most powerful marine inverter available with a continuous power rating of 3,000 watts.
This is more than enough wattage to run multiple electrical appliances that require a large amount of power to run i.e. refrigerators.
There are 4 AC outlets that you are able to plug into with built-in over and under-voltage as well as overload protection.
GoPower provides a 1-year warranty as peace of mind, which is good to know before purchasing.
As with the other expensive alternatives, the Go Power uses high-quality sine waves to provide excellent AC power.
The Go Power is available in 1,000, 1,750 and 3,000 but the latter is the one to go for.
ProMariner TruePower Plus
ProMariner TruePower Plus modified sine wave and pure sine wave inverters are designed to convert 12 VDC battery power to 115 VAC and will automatically pass through AC inlet power when present.
The TruePower Plus is rich with features that include an innovative dual color digital LCD message center and dual color gages for AC power output.
There is also a USB power port, GFCI convenience outlets, DC cable covers and a separate on and off remote.
The integrated AC cable strain reliefs and front screw connection terminal blocks allow for quick and easy installation without the added need for ring terminals for AC power connections.
Designed with soft start noise filtered technology and x2 surge capability for powering demanding loads.
Shock-resistant construction with internal conformal coated electronics for protection in harsh environments.
VOLTWORK S2000w DC 12V
VOLTWORKS provides multi-protection. Those protections include input over-voltage/under-voltage protection, output short-circuit, over-load, over-current, over-temperature protection, and short curcuit protection.
The reliable cooling fan is energy efficient and much quieter to dissipate heat throughout operation. The cooling fan is started at ⅓ of the rated power of the inverter.
The VOLTWORKS is of high quality aviation aluminum body that has a strong heat dissipation and alloy case that ensures a durable product.
With a cable length of 15 feet, this will be easy to control the on and off of the inverter. The panel of the remote control can also display the battery capacity, and there is a reminder of fault. This makes it convenient to know the battery capacity and the condition of the machine at any time.
The fast-charging inverter has 2 USB ports and 3 AC outlets for simultaneously charging most devices. Dual 2.4 A USB charging ports great for charging your iPod and smartphone. This is great to have for vacations, outdoors, road trips, or for your emergency kit.
Marine Inverter Buying Guide
What to Look For in a Marine Inverter?
Ensuring that you have enough power when out to sea can be taken care of by the recommended inverters for boats above.
Many include additional features such as built-in cooling fans, USB ports, multiple AC ports, safety protection, and much more.
The inverter works with your waterproof boat battery and will even charge it with some devices such as the ProMariner.
Inverters vary in budget massively and it’s important that you get the best value for money by considering all the factors.
The power ratings of marine inverters are determined via the wattage. The two ratings that brands state are continuous and peak wattage with higher wattage resulting in a higher purchase price.
Many electrical appliances require a certain amount of continuous wattage in order to function correctly.
If you are planning on powering many refrigerators and other large appliances, it’s recommended that you purchase a high wattage marine inverter.
The more expensive marine power inverters will use a Pure Sine Wave as opposed to the Modified Sine Wave.
The modified waveform is much cheaper and works well with the majority of electrics.
However, if you are using the inverter for sensitive electronics such as computers or stereos, the Pure Sine Waveform is recommended.
A charger integrated into an inverter is an expensive feature and we have mentioned above that the ProMariner is the best marine inverter charger.
However, other features such as remote controls, surge protection, heavy-duty construction, and additional AC outlets are all highly desirable.
Where Should the Inverter be Installed?
The inverter works with the battery and its important that they are close together to avoid voltage drops and long wires.
As a rule of thumb, we suggested staying under 10 feet away from the battery bank that is completely dry and is ventilated.
Marine Inverter Efficiency
The efficiency of inverters for marine applications usually run at a 90% efficiency rating.
However, the waveform quality can reduce or improve efficiency. For example, if the inverter was to use a Pure Sine Wave Form, it will run better overall and will use less power.
For boats that are docked up all the time and use power from the shore, an inverter is not an essential product.
However, when you go out to sea and require reliable AC power, the marine inverter will be required to convert the power.
The recommended marine inverters above will all convert the direct current to alternating current for use with domestic electrical appliances.
