8 Best RV Inverters For 2019 – Buyer’s Guide

Are you a boondocker? Or perhaps you are like me planning to own a RV (recreational vehicle), then there is no doubt that you’ll be needing an RV inverter—not just anyhow RV inverter—but the best RV inverter. When you need to power electrical appliances including TV sets, Microwaves and your crock pot that requires 120-volt alternate current with a Direct current, then you need the best RV inverter. So, how do you choose the RV inverter that best suit your needs, continue below…

How to choose and things to look for to buy the best RV Inverter?

Choosing the best RV inverter may seem a daunting task. In choosing the best RV inverter, you have types to search for, cost to look at, and a few unique highlights to understand. Mainly, your choice of selection could be a 3000-watt inverter for recreational purpose or search for inverters with cutting-edge highlights, for example, heavy duty and built-in cooling fan. In the end, it can become frustrating, when choosing the fundamental features and highlights, which will best suit your requirements.

Well, let’s help break down the necessary things you need to look out for in your selections:


The best way to choose the size required is for you to know the summation of the watts required for your appliances. The fact that 3000-watt inverter for RV gets the job done; doesn’t imply that you also need to get it. After getting the summation of the power watts that will be required, then it is wise that you add, say an extra 15% more to encourage a touch of overhead.

RV inverter comes in two ratings: continuous and peak. Although the spotlight may be on continuous rating (in watts) devices such as microwaves, air conditioner requires a higher peak rating. In this way, it advantageous to pick in like manner. Aside from air conditioner, everything   else is sensible as far as watts are required.

Waveform Output

According to the waveform generated from a DC source, there are two types of power inverters as per the AC output’s waveform: pure sine wave and modified sine wave. However, it’s necessarily you take into consideration the result which is either pure or modified sine wave.

While pure sine wave for an RV inverter can run all appliances and generate a cleaner form of output than modified sine wave—modified sine wave is more affordable and can’t run most appliances. A modified sine wave can also cause some interference with some appliances. So modified sine wave is only best for non-digital tools such as microwave oven and lights etc.

Battery Power

It is fundamental to see if the available battery power is sufficient or not. To get the amount of energy your batteries needed, you divide the summation of power consumption in watts by 10. If the general wattage of all gadgets you wish to operate at the same time is 500 watts, then the battery’s power ought to have the capacity to render 50 amps.


Checking the inverter’s efficiency is vital as the voltage conversion from DC to AC generate heat, more watts utilized from the battery by the inverter than emitted. One thing you should have in mind is, RV inverter consumes some battery power even when there’s no gadget connected to it. Hence you should always switch it off when not in use.

Operation Time

How long will an inverter last depend highly on the battery’s capacity measures in Ah or Amp/Hour couple with the overall wattage of the appliance you used. To get this, get the battery’s Ah rating and divide it with the Amps the inverter need to run all the appliances simultaneously. Take for instance, as calculated above, assume the current consumption is 50 Amps and the battery’s capacity is 150Ah. Consequently, the operating time of the RV inverter will be 150Ah/50Amps which is 3 hours. This implies a fully charged 150Ah battery power will run a 500W load for 3 hours.

The Benefits Of Rv Inverters

Usage of Luxury Items

On the chance that you live off the grid and need to power luxury appliances like PCs, microwaves, and TVs, then your best bet is either shore power or an inverter. This item can’t run on a solar panel or battery alone; you require an inverter that gives you the advantage to run these luxury items.

It Prolongs The Life Cycle Of The Appliance

Like, discussed earlier, that pure sine wave generates cleaner and deliver high-quality power that won't shortcut your appliances operating life. This will as well save you cost or repair and replacement.

Usage Of Shore Power When Available

Another exciting thing is you can still make use of shore power when you have the means to connect to the grid since RV inverter can also deliver power into the AC devices, so it makes sense to have them in the RV. 

Best Ways To Use Rv Inverters

  • Of course, you won’t want to use your RV inverter carelessly, so to ensure an effective and smooth operation, it is advisable to use it with a fully charged battery. The battery should also be in excellent condition since a weak battery can quickly drain.
  • Ensure that when using a power inverter your car's wires are working in a way that is compatible with the current one.
  • Check its compatibility before connecting the device to a cigarette lighter.
  • Be sure to use your fans in areas with proper ventilation.

Addessing Rv Inverter Controversies

Which Inverter Is A Better, Pure or A Modified Sine?

All inverters convert DC power to alternating current. If you work with heavy equipment that does not care about the quality of the energy, the modified sine energy is perfect.

What Happens When RV Inverter Goes Bad?

The RV inverter, which is malfunctioning, will stop working properly. This leads to power failure, unit failure or malfunction, and significant financial losses.

Do I Need To Enable/disable RV Inverter?

To properly use your motorhome inverter, you also need to understand when to turn the unit on or off. To determine when to include your RV inverter, it would be best to answer the question of whether your vehicle is equipped with a charger or inverter.

Which is A Better 12-volt Device Better In A 110-volt RV With An Inverter?

In an average RV power is either—12 volts DC and 120/110 volts AC. A 12-volt power system can be seen as a working pump that pumps water from containers into showers and faucets, lights, horns, and blowers. While a 120/100 run major roof AC and other household appliance
