Buying Guide — Choosing Your Own Power Inverter

Best Marine Power Inverter ReviewsQuality power inverters will ensure you a 120V AC source of power throughout your boating trip. Although most inverters achieve this, what you will choose can still vary depending on how many devices you need to hook up to it. Regardless, these are often user-friendly in terms of everyday usage and installation.

The size and wattage of your inverter depend on how many items it needs to power. For example, if you are just hooking up a TV, a small one will do. But adding other appliances such as a refrigerator, stove, or microwave will demand stronger inverters. Remember that greater wattage will also use up your boat battery faster, so possibly invest in battery banks as well.

Aside from being a steady and protective power source, power inverters are also made to regulate the electricity if ever a power surge occurs. This way, any electronics that could be damaged from a sudden burst in electricity will be protected from that.

Wave Form

There are two waveforms an inverter can take on: a pure sine wave or modified sine wave. Inverters with modified sine wave types are good as a more affordable power source for your devices. Inverters with pure sine waves are more efficient in equally distributing power. They may be more expensive, but if you have sensitive devices, it is a better investment.

Continuous Wattage

Every inverter will be marked with a number for peak wattage and continuous wattage. A higher number will end up costing more. The number of continuous wattage will also indicate how many devices it can handle simultaneously.

Do this by taking the sum of the wattages of all the appliances you will plug in. If that sum is less than or equal to the continuous wattage on the inverter, then it should be stable. Take note that you can convert volts to watts via multiplying that number by the current in amperes.

A safe bet is buying an inverter with a greater sum than your current wattage sum. This way, you have some room for extra appliances, and your inverter will surely not be overloaded. Also keep in mind that inverters are not 100% efficient, and so there will inevitably some voltage lost in the process.

Batteries and Wiring

Inverters themselves have to be hooked up to a battery supply to function. These will run on 12V batteries, and how fast it drains depends on how much wattage it distributes. You have to ensure that the batter is correctly and securely wired to your inverter.

Inverters usually come with instructions from the manufacturer on how to maximize battery life. It is usually not good to completely drain a battery, both for the inverter and the battery itself. Instead, get another battery charger to go with it, or make sure you can attach it to a shore generator.

Another way of recharging the battery would be through an engine alternator. It will charge the battery for as long as the engine runs. Batteries can also charge via wind or solar power. Another option would be simply buying an inverter with a charging implement. One such inverter is reviewed on this page.

Be sure that you have wired everything correctly according to the instructions. Be conscious that a 120V alternating current, when wired improperly, can electrocute a person.

Other Features

There are extra features that an inverter may have that can increase safety. There are some inverters with screens that show pertinent information for the user’s benefit. This would include the remaining battery charge, voltage, power, etc. Some inverters include extra outlets. Others even have USB ports on them, in case you need USB charging. It is also advisable to get a cooling fan that can handle the heat the inverter will inevitably produce.

Convenience-wise, some inverters come with remote switches. More expensive inverters might come with a charger integrated function that can charge batteries as it is plugged into a generator.

Frequently Asked Questions

Here are the questions we most frequently hear about marine inverters.

How Do Power Inverters Work?

Inverters are used to convert a constant 12V power source into a 120V Alternating Current source. The power source it draws from would be a boat battery. These can then power your appliances while on the boat. These appliances could be a TV, stove, microwave, and others from your household. It is also advisable to use a separate battery for this from your engine.

Although people often keep both a power generator and inverter, the latter is a great substitute for the former. Inverters are much more compact than an entire generator and run much quieter. Generators still supply a lot more power, but if it is not necessary, we advise you to get an inverter.

Are Marine Inverters Better Than Auto Inverters?

Auto power inverters mostly use a modified sine wave current. Although this is not bad, marine power inverters that specialize in pure sine waves are much more advisable for sensitive devices. This is because they can control any power surge or electric bursts. Marine inverters are still more expensive, of course, but are worth the investment.

What Is The Input And Output Of A Marine Inverter?

Marine power inverters run using 12V batteries. How much it outputs depends on the model itself. This can range anywhere from 100 watts to 3000 watts. Just remember that the larger the inverter is, the faster it drains your battery. It would be good to find a moderate output so that it will not drain the battery so quickly.

Where Do You Install An Inverter?

Inverters are best placed next to a battery bank, or as near as you can put it. Don’t put it any farther than 10 feet away from a battery bank. Anything longer can cause a drop in voltage or a loss of power and efficiency. There may also be a greater chance of electric accidents happening if the distance is too far. Keep it away from water as well, and keep it well-ventilated so it can cool properly.

Before you go and make your purchase, we have some final tips for you to keep in mind.

Marine Power Inverter Review Conclusion

Power inverters are great for supplying an alternating current to your sensitive appliances. They are an affordable option compared to generators and will fit well for the needs of your boat. There are also generally easy for users to wire and install themselves, as long as you keep it within 10 feet of your battery source.

Power inverters can also come with several other features, such as screen panels, additional charging, remote switches, and USB ports. They are not completely efficient, but high-quality ones can reach up to 90% efficiency. As long as you consider the aspects discussed above, you will be safe and sound with a good-quality marine power inverter.
