The Basics of an RV Inverter

Before moving into the discussion about types of inverters and what things one should consider while buying the best power inverter for camping, let’s delve into the motorhome inverter basics.

What Is an RV Inverter?

Although it may sound surprising, an inverter is also a type of converter. Its principal function is to convert DC power to AC power. This machine allows the battery to run AC compatible appliances. At a given time, an inverter can convert only a designated amount of DC.

Inverter ensures power supply to an RV.

How Does It Work?

An RV inverter converts the battery power from 12V DC into 120V AC. With a large inverter, you can use RV batteries to supply energy to almost anything, including refrigerators and AC units. So, to provide power to the large appliances, you will require a large inverter as well as robust RV batteries to produce the energy from 12v DC to 120v AC, which involves a 10x increase in power.

During the conversion process, some power loss takes place. Usually, inverters waste a maximum of 10% of the power, while the best RV inverter with superior quality and performance loses only 5%. To cut costs, choose the most efficient inverter that is available to generate power for a wide variety of appliances.

Benefits of RV Power Inverters

For modern-day campers, inverters are almost indispensable due to their multifaceted benefits. Two most unique advantages to expect are:

Having an inverter in the motorhome means having a steady source of AC for all devices and appliances. There is no need to worry about the battery power as keeping the devices fully charged becomes easy.

By pairing up the best RV inverter with a converter, it’s possible to run the appliances and charge the RV battery simultaneously by using the shore power.


Types of the RV Inverter

Here is a comparative discussion about the types of RV inverter that are currently available in the market as well as their unique features.

1. Pure Sine Wave Inverter

When it comes to price, an RV pure sine wave inverter is costlier than the other varieties of inverters. However, people prefer this since it delivers cleaner power for the appliances of RV and travel trailers. It is specifically suitable for sensitive electronics, such as laptops, refrigerators, and smart devices.

A pure sine wave inverter.

You can use this without any worry as all appliances can work at their full capacity with this inverter. Battery chargers also function well with it because of the quality power it provides. In short, the best pure sine wave inverter for RV is compatible with all the appliances and tools available currently in the market.

2. Modified Sine Wave Inverter for RV

The prime attribute of a modified sine wave inverter is its waveform that suits almost all kinds of appliances and equipment one can find nowadays. But keep in mind that this inverter can reduce the efficiency of some appliances. Moreover, electronic devices like fans will consume more power while they fetch power from this power inverter.

So, this inverter is not as efficient as a pure sine wave inverter despite being more affordable. Its power consumption rate is 20% higher than the earlier one. Sometimes, it also causes more sound pollution by making a buzzing sound while operating.

3. Square Wave Power Inverter

It is the best RV inverter on the market in terms of cost-effectiveness. But at the same time, it is less suitable to be used in RV and travel trailers. When it comes to providing power to simple devices, there will not be an issue. For example, this inverter is perfect for tools with universal motors.

However, most of the contemporary appliances of RV require a complex power supply that this inverter is unable to supply. That is the reason why not many people would choose square wave inverters for their motorhome.

4. Portable RV Inverter

Portable power inverters come in small sizes and less weight. For these reasons, it’s possible to transport it from one place to another without any difficulty. They can also use this inverter outside the RV, such as in a remote location, at home, during a picnic, inside the tent, and more.

Those who need to move their inverter would prefer the portable unit over other types. It is versatile in terms of functions since it works perfectly for off-grid camping and solar panels.

5. Heavy-Duty RV Inverter

As the name suggests, this inverter is durable and ready to deal with heavy usage. Besides, it has additional features to support durability like protection against overload, overheating, and short circuits.

There is also a built-in cooling fan for damage prevention that starts to operate automatically when the inverter reaches a particular temperature. Any remote location that needs a backup AC power source of power will find this heavy-duty inverter useful.

Ordered this to replace the MSW Duracell Inverter (Xantrex) I had installed some time ago in my RV. The old inerter never worked well, and could not ever support it’s rated load. I looked at this as a low cost option to replace that old inverter that went into unexplained intermittent restarts under any type of load, it became too annoying to use. I tested this unit last eve, before I do final install.. I want to verify it works.. IT DOES. In fact, it is frankly amazing. I gave it a full load test, even started the RV AC (a brief beep of complaint, then AC compressor comes to life) and I ran it for awhile, trying to get this thing to heat up so I can hear the fans kick in.. It ran, and ran, and barely got warm.. then I ran 1200W water heater, 750W space heater, 300W fridge, at same time.. finally, the fans kicked on for about 30 seconds (actually barely audible, so that is another plus), then they shut off while still under load.. it was barely warm to the touch, and the entire time the voltage was in the green band on my AC side volt meter.. This is an amazing value for what it is capable of doing. I’m looking forward to having a unit that actually WORKS for a change.. Definitely recommend this unit. NOTE, DC current is a must, I have 2 NEW Group 29 size Deep Cycle batteries to run this thing, be sure to have plenty of DC side power, and good, clean, tight connections with large (or doubled up standard) cables. If you use those provided in the box, use BOTH red and black, and tighten the connectors with pliers.. the AMPS on the DC side will always be critical to large AC side loads this thing is capable of supporting.

I purchased the 2,000 watt version of this low frequency pure sine inverter through Amazon this spring and installed it in my motor home and love it. This was version 2.0 of my generatorless electrification project. I was tired of starting the Onan generator every time I wanted to run the microwave or brew some coffee. I had first purchased a modified sine 3,500 watt inverter which I powered from 4 six volt golf cart batteries. The modified sine unit was good but my microwave and other electronics didn’t like the square wave. Another problem is that the AC voltage declined all the way down to 85 volts as the batteries discharged. My Aims unit puts out 121-123 volts at 60 cps all the way down to low voltage cutoff.

Why do you want a low frequency inverter rather than a high frequency? These units have huge copper coils and can output 3 times their rating for up to 20 seconds. Even the 2,000 watt unit runs my air conditioner which requires nearly 5,000 watts on startup.

The battery charger on the 3,000 watt unit is rated at a maximum of 100 amps and 70 amps for the 2,000 watt unit. I pack a 2000 (1,600 continuous) watt inverter generator for emergency charging. With my solar charging, running my fridge on gas, and frugal use of the inverter, I only rarely have to use the generator. The problem is that the circuit breaker will trip on this generator at the full charging amperage of the inverter. Aims has a solution for this problem with a dial on the control panel where you can turn down the power diverted to charging. I adjust this to where the generator runs at a comfortable 75% of it’s top RPM and the batteries still get charged fully within a couple of hours. Another nice feature is that the inverter doesn’t switch to shore power until 15 seconds after you connect it. That will give it time to spin up and warm up a bit before taking the load if it was connected at startup…..

Excellent quality inverter with plenty of power provided you have the batteries proper cables to feed this beast. I mounted the inverter in my utility bay and when boondocking I simply plugged my RV power cord with 20 amp adapter, into the inverter – no transfer switch needed. Now all my outlets can have 110v power and there’s no way to accidently backfeed into grid in a regular campground because the power cord is either plugged into the inverter or the power post. I make sure to turn the inverter off when not in use so phantom loads – like the on board converter/charger doesn’t drain the batteries.

I didn’t have an opportunity to travel in the RV so the unit sat there unused until July. Prior to my travel plans, I tested all the systems in the RV and the inverter was alarming for no discernible reason. After trouble-shooting and having a technician look at it, we determined that something was malfunctioning on the inverter. I was quite dismayed because I had a trip planned a couple of weeks out and I imagined I would probably have to buy a new inverter and write the Potek off as a loss in order to leave on my trip as planned. I contacted Potek expecting to be told I’d needed to send in the malfunctioning inverter to resolve the issue and so on. Nope, they immediately sent out a new replacement inverter – and it arrived before my planned trip. There was no cost to me for the replacement. Awesome customer service!
