Types of RV Inverter

There are uncommon types of power inverters from 12V to 220V. They differ in terms of output power, the method of connection to the source of electricity, and the fields of application. There are two major categories: the changed sine wave inverter and the pure sine wave inverter.

1. Changed Sine Wave Inverter

The changed sine wave inverter has a meager price and is suitable for most commonly used electronic devices. But this inverter for motorhomes has positive and negative half-waves that are not entirely rounded with the consequent imperfection of the emitted current.

Therefore, it is not suitable for many power supplies for electronic equipment. The changed sine wave inverter for motorhomes is only satisfactory for those who do not have particular needs.

In changed sine wave inverters, it modulates the voltage by two digital signals, one that controls polarity and another that controls the presence or absence of the output voltage. Non-motorized appliances such as TVs, computers, and chargers, which only have the transformer, are suitable for the changed sine wave inverters.

2. Pure Sine Wave Inverter

The second inverter from 12V to 220V is a pure sine wave. It has a cost approximately three times higher than those with a changing wave. It produces perfectly rounded waves and provides constant electricity like ordinary households.

Therefore, it is recommended for those who need to connect vital medical equipment, appliances that require a long time of use.

Denote that the inverters for change-wave motorhomes consume more electricity than those with a pure wave. SO, during their use, they can have dropped inefficiency, and it means that the electrical consumption is higher.

In pure sine wave inverters, the second stage is more complicated. The voltage is pulse-modulated and then filtered, thus getting a sinusoidal voltage equal to that of the home network.

Pure sine wave inverters are more efficient than changed sine wave inverters. They cost a little more but guarantee more significant efficiency. Appliances equipped with a motor require to be powered with a pure sinusoidal voltage, which otherwise a square wave would damage them.

How to Choose The Best Power Inverters For RV

Here are some factors to consider when choosing an RV inverter. Consider what you need to make sure you can buy the right model at the right price.

1. Purpose

Probably, the most crucial factor is the purpose of why you want to buy the inverter. If you just want something to keep in the RVs to recharge your kids’ phone or tablet frequently, you can purchase a smaller device with a 12-volt adapted.

If you are outdoors and want an electrical supply for your devices when camping in open spaces, you may need a more powerful inverter.

2. Dimensions

If you just want to charge your phone or some other similar device simultaneously, we recommend taking an inverter that weighs relatively little and is small. It can fit in the glove compartment, and you can use it as long as necessary.

3. Safety

A right inverter must have excellent safety features to protect the objects it is loading. You should look for inverters with overvoltage protection, overload protection, and short circuit protection to prevent damage to your electrical products.

There should be temperature protection with a sound cooling fan system. The top-of-the-range models should also allow you to manage direct and alternating current power via multiple fuses mounted inside. For instance, wicks add a level of protection.

4. Price

The prices for these items range from less than 50 dollars to over 300 – 400 dollars for a 12V connector. To some extent, though, you must have some extra-payments.

A low-priced inverter will struggle to generate the energy needed to operate large electrical devices. A more expensive one will probably have multiple safety features, making it better for the appliances’ long-term operation.

FAQs

1. What is the inverter?

A power inverter transforms the direct current generated by a 12V battery into a conventional 220V alternating current with a sine waveform. You can use it to operate many devices: electric lights, kitchen appliances, microwaves, utensils, electrical, TV, radio, computer, etc.

A pure wave inverter can power any electronic device, even sophisticated with premier power.

2. Can power inverters damage the RV?

If misused, a power inverter can damage the car battery. But if you use it correctly, the impact is minimized and will not cause any danger to you and your devices.

3. How long does a 12V battery last with an inverter?

It starts from the load you are consuming, for example, 65W/12V is 5.42A, and the battery life is 100Ah/5.42 = 18.45 hours. But the inverter is never 100% efficient, so let’s say about 17 hours.

4. Do the power inverters drain the battery?

Inverters can also drain the battery quickly unless the motor is running and recharging the battery. Most inverters sound an audible alarm when it detects a reduced power source. But it may be helpful to purchase a slightly more sophisticated and expensive unit that turns off when it detects a low battery.

Final Verdict

Those who spend a lot of time in the RV for work or traveling with the family can enjoy having the best RV inverter in their motorhome. Devices such as smartphones, tablets, notebooks, power banks, or other electronic devices can be recharged or connected with no problem.

We have given our preference to the Giandel 2000W Pure Sine Wave Power Inverter. It is an inverter that makes use of the functionality. At the front, there is a power outlet suitable for plugs used throughout Europe and a USB port. In the rear position, there is instead a fan that ensures the correct cooling of the device.

If you want an inverter that offers the best protection feature, WZRELB Pure Sine Wave Inverter is a more suitable choice. If you have questions, please leave it in the comment section!
