How To Choose The Best Marine Power Inverter – Buying Guide

How_to_Choose_A_Marine_Power_Inverter

Continuous Wattage

A good power inverter is powerful enough to power all the devices you use on the water. The manufacturer will state the continuous wattage and peak wattage. The continuous wattage rating shows you how many appliances the charger is capable of running at the same time.

You can check the wattage on the devices you’ll be charging and sum the wattage to determine your power requirements. For appliances showing amps, you can covert these into watts by multiplying with volts. For example – 2 amps x 120 volts = 240 watts.

It’s always a good idea to buy a larger charger than your power sum to avoid overloading and also because marine inverters have about 90% efficiency. Of course, the best marine power inverters with higher wattage are going to cost more.

Wave Form

Inverters can have either be modified or pure sine wave forms. Modified sine wave inverters are generally more budget-friendly and a solid power source for most things. On the other hand, pure sine wave inverters have better efficiency power factor – they create more power and give out clean power similar to the one at home. This is why this type of waveform is recommended for more sensitive electronics to work properly.

Other Features

Some additional features can make the boat charger both easier and safer to use. Some products have power, voltage and battery monitors. You can also get chargers with additional power outlets, and USB ports. Having an efficient cooling fan is also a good idea to prevent the charger from overheating and causing harm.

The inverter should be designed in such a way to control power surges so there is no damage to sensitive electronics like your computer, cell phone or stereo. An inverter that comes with a remote control panel offers greater convenience. Finally, there are inverter-chargers with battery chargers integrated – this means they can power-up the batteries when plugged with shore power or generator.

Batteries and Wiring

Inverters need a steady supply from the batteries to covert direct current to alternating current. They run on a 12V battery, and larger inverters drain a lot of power from your battery bank. So choose a good marine battery or powerful battery bank to run it and handle it according to manufacturer’s instructions to get the best life. You can buy a battery charger and plug to a shore power line or generator.

There are also engine alternators which can recharge the battery while the engine is running. Alternatives are solar panels or wind generators, or you can invest in an inverter with a charging function. When it comes to installation and wiring, you should follow the manufacturer’s instructions. Keep in mind that the inverter converts the DC power to 120V AC, which can cause electric shock and serious injury.

FAQs

What_Do_Power_Inverters_Do_and_How

Q: What Do Power Inverters Do and How?

A: 

Power inverters use the 12V power from the marine battery to translate it to 120V AC which you can use for powering appliances on-board, when you head out to sea. Because it uses batteries to do this, if you don’t have some sort of backup system it’s a good idea to have separate batteries for this.

Q: Why Choose Marine Power Inverters over Auto Power Inverters?

A: 

Marine power inverters generally represent a higher quality power source, and a better choice for sensitive electronics. This is especially true for pure sine wave inverters.

On the other hand, auto power inverters are usually modified sine wave type. This is a more cost-effective charger solution, and they don’t have such high requirements as marine power inverters. They are used to power small devices through the car lighter jack.

Q: How Much Power Does an Inverter Need and How Much Does It Produce?

A: 

An inverter needs a 12V battery source. Larger inverters will drain the battery quicker, so it’s good to have more than one battery for this, or a charging solution. As for the power it produces, it can range from very small inverters with 100W output to large chargers which give out over 3000 continuous watts.

Q: Where Should the Inverter Be Installed?

A: 

General recommendation is to hardwire the inverter as near the battery banks as possible. The distance should be under 10ft, to avoid unnecessary power loss and voltage drops, as well as to reduce the chances of a hazard occurring. The place where you store it should be dry and ventilated (getting a waterproof power inverter for boat is a good idea), and this goes for storing the battery too.

Globo Surf Overview

Boat inverters present a very reliable AC power source to meet your power needs when you’re not docked. Investing in a good power inverter allows you to have a steady AC supply on board. Compared to a generator, inverter chargers don’t require fuel or an exhaust system and they’re more reliable than shore power. It comes down to your particular needs when choosing the best marine power inverter, but if you follow the guidelines we give here you won’t go wrong.
