Best Marine Inverters – Buying Guide

Best Marine Inverters reviewed

Have you ever imagined yourself sprawled out on your boat’s deck, gently bobbing up and down in sync with the waves? You can enjoy the faint caws of gulls overhead, a cold beverage in one hand & your TV remote in the other. How? Marine inverters are the secrets to taking your home to the water!

What is the purpose of a marine inverter?

A marine inverter works by taking DC (Direct Current) power from your boat’s battery bank and converting it to AC (Alternating Current) power. This makes it possible for you to use your favorite household items on your home away from home without the great expense (both money and noise) of a generator.

A marine inverter adds an extra layer of enjoyment to your boat by enabling you to use many of your essential items like a TV, refrigerator, laptop, power tools and even hair dryers.

Features to Look for

There are many features that you should keep in mind when making the decision of which marine inverter to purchase for your boat. Below we will take a look at what features are most important and should be considered when selecting the perfect inverter from those that are available.

Wattage

Selecting an inverter with the right amount of wattage is important. Deciding which wattage to go for is ruled by the maximum power needed at one time. If you plan on having different electronics running concurrently then you will need an inverter that delivers more than 1200W of non-stop power.

Wave Form

When it comes to inverters, there are two waveform options: Pure Sine Wave and Modified Sine Wave. Both Pure Sine Wave and Modified Sine Wave can provide power to AC appliances and you should decide which wave option to choose based on the appliances you need to power.

The main difference between the two is:

  • Modified Sine Wave power is an affordable, simple form of power and is suited toward powering simple electronics like your phone charger and other small appliances.
  • A Pure Sine Wave power is a power equal to the power in your home and is suitable for your bigger appliances like a refrigerator or TV.

It’s important to note that boaters and industry professionals alike recommend using Pure Sine Wave. Even though it’s more expensive it helps your appliances operate at optimum performance without the risk of damage. 

Power Surge Capacity

Most appliances have an estimated wattage, but many of them will surpass that estimate—sometimes by more than double the expected amount—when you start them up. We call this increase in wattage ‘surge power’. It’s important to make sure your inverter is large enough to cover these start-up ‘surges’ for the items you plan on running.

If you use an inverter that doesn’t have adequate surge capabilities the appliance will not start, and if it does it will not last long.

Wiring and Outlets

The first step of any inverter installation is connecting the DC power supply to the inverter itself. Every inverter, except for the smaller ones with built-in outlets, requires output wiring.

If you decide to do the wiring yourself, please pay careful attention to the manufacturer’s recommendations and instructions. Abide by all the usual ABYC (American Boat & Yacht Association) and standard marine practices.

Remember:
  • Use good quality marine wire and not your normal household wire as this is not approved for marine use. 
  • Keep your wires neat.
  • Use high-quality crimp connectors when making connections.
  • Keep all wires away from stowed equipment.

Installation

It is recommended that inverters be professionally installed because they draw a lot of amps. This means electrical fires and shorts can occur if not wired properly. An inverter becomes an integral part of your boat’s electrical system and your marine lifestyle, so it is best to err on the side of caution.

When installing your inverter, you should place it somewhere that is cool, dry and well ventilated. Keep it away from flammable fumes produced by batteries, engines, and fuels.

If you do decide to install the marine inverter on your own, make sure you have the necessary tools at hand and adhere to the manufacturer’s instructions.
