What to Look for in an RV Inverter
Choosing the right inverter for your particular vehicle is never easy. There are a few factors that every RV owner should consider before buying a new power inverter for their next trip.
The Type of Inverter
There are three main types of inverters from which you can choose, but not all three are created equal. They differ in cost and complexity as well as efficiency. Which inverter that will work best for you depends not only on budget constraints but also what equipment you want to plug into your RV.
Modified Sine Wave Inverter
A modified sine wave inverter, also known as a “stepped sine” inverter, is a popular style due to its affordability. They can be up to five times cheaper than comparable pure sine wave inverters, which I’ll go over in the next section. However, it’s important to remember that the price difference is because modified inverters use older technology.
While a modified sine inverter may work fine with most low-power appliances, however, newer and more complex devices such as computers and LED TVs can overload the system. This style of inverter is more prone to overheating and damaging electronics. Some models can also be loud enough to be heard from the cabin of your RV.
Sine Wave Inverter
Sometimes referred to as “true sine” inverters, this type of device is much more efficient than similar modified sine wave products. It’s also safer for electronics that draw a lot of power, especially newer devices. Not only are they less likely to fry appliances, but many true sine inverters are also protected by a GFCI.
While sine wave inverters may be more versatile and efficient than other options, they can also be significantly more expensive. However, for those with the budget for it, a true sine inverter will work with just about any onboard devices.
Square Wave Inverter
The least common style of inverter is the square wave inverter. This is a simple device that’s able to run basic appliances and electronics with no problem but struggles with high-power electronics. Though it has a fairly limited capacity, square wave inverters are generally the cheapest option available.
The Size of the Inverter
The size of an inverter doesn’t refer to how much space it takes up, but rather, the power rating. Each inverter is rated in watts to show which appliances it’s compatible with, and which require too much power for the system to handle. You can find models ranging in size from just 50 watts to as much as 50,000 watts.
You should always consider your average power output when looking at inverters and choose one that can comfortably handle your needs. This includes your typical power, which is the amount that you need to run your electronics continuously, as well as your peak power requirements.
An inverter’s surge power allows you to run additional appliances for a limited period of time, eventually hitting a maximum power output. Usually, surge power allows you to increase your energy consumption for around 15 minutes.
Input and Output Voltage
Your electronic devices aren’t the only things at risk if you choose the wrong inverter for your RV. You also need to make sure that the device is compatible with the voltage of your vehicle’s battery. Otherwise, it may end up causing damage that can lead to costly repairs.
It’s important to remember that electronics from different parts of the world require different power sources. For instance, those of us living in the U.S. along with people in Canada, Mexico, and some parts of Central and Latin America use electronics that need 120V AC power. In other parts of the world, however, most electronics use 220V to 250V AC power.
Power Rating & Watts
Power ratings can vary widely between different RV inverter models, all the way from 50 to 50,000 watts or more. The amount of power you need in your motorhome will determine what power rating you need. Make sure to check the maximum surge as well, which will tell you how long the inverter can sustain that maximum power level.
Wattage is another important consideration here. While the max power is nice to know, the watt rating should also tell you how many watts of power the inverter should sustain when it is running normally.
When using limited power from your RV’s battery or from solar panels, you want to be conservative. The more energy-efficient your inverter is, the lower your energy consumption will be. You can also feel good knowing that you’re taking steps to reduce your carbon footprint as you camp.
Pure sine inverters tend to be the most energy-efficient style. However, many RV enthusiasts are hesitant when they see the price tag that goes along with top brands. It’s important to shop around and do your research before buying an inverter to find one that balances both cost and efficiency. With a little bit of research, you can find the best RV inverter to make your next outing a success.
