How To Choose The Best Inverter Generator For 50 Amp rV?

Planning an RV camping trip brings the challenge of selecting the best inverter generator for 50amp RV. We have compiled all the essential points you must consider before buying your inverter generator.

Choosing the Right Size for your RV Requirements:

  • Before buying your first generator, you must be aware of your RV’s electric consumption requirements. Your air conditioner will take most of the power of your generator. Other power-consuming appliances are microwave and refrigerator.
  • The air conditioners require greater wattage for starting, and then this value decreases while the air conditioner is running. A 13,500 BTU air conditioner requires at least 3000 watts to start.
  • Once the AC starts running, you can turn on the other appliances like the fridge, microwave, TV, coffee maker, or toaster.
  • Determine the required wattage by adding up the starting watts of all necessary appliances you will run in your RV.

Consider the Noise Level:

  • A 50 Amp service means that you will probably use a bigger inverter generator. Though inverters are designed to produce minimal noise, bigger inverters are the noisier than smaller ones.
  • Most of the generators produce 60 to 80 dBA. The inverters are equipped with many noise cutting features which may increase their cost. These inverters are the best option when you are buying for RV camping.

Consider the Portability:

  • Buying a generator with much greater power than your RV requirements will just add to its weight. Portability is another most vital factor to be considered when buying a generator for RV living.
  • Increased weight means decreased portability. A 200 pounds generator is impossible to lift and difficult to drag. Therefore, you must choose your inverter, which comes with built-in wheels and ergonomic handles.

Consider the Type of Fuel and Fuel Efficiency:

  • Most inverters run on gasoline. Some inverters allow you to switch between gasoline and propane. Consider the convenience and availability of fuels. Fuels burn on their consumption rates. You can check the fuel efficiency from the product descriptions.


  • It can be the worst scenario: you are camping in a secluded forest, and your generator shuts down for no apparent reason. Are you horrified? Don’t spare a few bucks to compromise on the quality. More costly inverter generators are usually made of high-quality materials under strict quality control producing procedures. It is advisable to buy from reliable names in the generator industry like Champion.

What Is Inverter Generator? Do You Need An Inverter Generator For RV?

Inverter generators convert the AC power into DC power, which is again converted into AC power using a high-frequency process. This process prevents power fluctuations and produces clean electricity with a Total Harmonic Distortion (THD) range below 5%. The inverter generators are composed of an alternator, an inverter, and a battery. They usually deliver output at the rate of 120 Volts at 60 Hertz.You can use both conventional and inverter generators for RV. Most of the RV enthusiasts prefer using inverter generators because of their distinct features. These features are more suited to RV camping, tailgating, and other outdoor uses than running heavy equipment at job sites. Homeowners may use both conventional and inverter generators. The features which make inverters the best choice for RV are as follows:

  • Clean electricity with less than 5% THD ensures safe charging of mobile phones, tablets, and laptops.
  • Quiet operation makes it suitable for use in peaceful and natural environments, campsites, and RV parks.
  • They are easy to carry around while enjoying your picnic or RV tour because of their relatively lightweight.
  • If you intend to run more appliances, you can simultaneously connect two inverters to an RV.

What Is The Difference Between An Inverter Generator And A Regular Generator?

Typical generators run full tilt to produce electricity. The inverter produces electricity when the engine throttles up and down. It results in increased fuel efficiency.

  • Type of Current Produced:Conventional generators produce AC electricity while the inverter generators produce electricity by converting AC to DC and then again DC to AC.This conversion creates a Sine Wave, making the inverter deliver clean electricity with low harmonic distortion (less than 5%).The conventional generators create irregular sine waves causing a lot o harmonic distortion. They are relatively safe for heavy appliances, but they can damage intricate devices with microprocessors.
  • Power Output:Conventional generators produce more energy than their inverter counterparts. It is due to the mechanical differences and type of motor used in both. Fuel tank size also affects the power-producing capacity of the generator.Inverter generators usually come with a power range of 1200 watts to 4000 watts. However, conventional generators can deliver more than 10,000 watts.
  • Fuel Efficiency:Their energy and fuel-saving features characterize inverter generators. They consume a lesser amount of fuel during electricity production. They also adjust to the energy load of your RV. Therefore, they come with smaller fuel tanks.Conventional generators do not offer any energy or fuel efficiency features. They have larger fuel tanks, which make them heavier than the inverter generators.
  • Portability:Conventional generators are more massive in weight and bigger in size than the inverter generators. People who spend most of their time on RV know how difficult it is to carry a heavy, bulky generator. The inverter generators are an ideal choice for RV living, camping, and tailgating.Conventional generators are lightweight and compact because of their small size motor and fuel tanks. They can be conveniently dragged with their handle.
  • Noise:No matter how many noise-reducing features are introduced, conventional generators will always remain noisy. It is because of their mechanics.Inverters produce relatively low noise than the conventional ones. They run smoothly at 3600 RPM, which ensures quiet operating.
  • Parallel Connection:A parallel connection can be installed when using inverter generators. The parallel connection allows you to use two inverters at the same time to get double power to run your appliances. Conventional generators do not offer this feature and should be bought after a complete assessment of your requirements.
  • Emissions:The gases emitted by generators may have profound effects on the environment. EPA and CARB compliance denote that the gases are emitted only in a small quantity.1
  • Price:The price of inverter generators are more than conventional generators. The inverter generators are built on most modern technology and come with the latest features, making them efficient and versatile.

Comparison between the Conventional and Inverter Generators:

Feature/ Characteristic Conventional Generators Inverter Generators
Power Output Greater than inverters Less than conventional
Fuel Efficiency No Yes
Clean Energy No Yes
Weight Heavier Lighter
Noise Produce loud noise Produce low noise
Parallel connection No. only one generator can operate at a time. Two inverters can be connected.
Price Cheaper than inverters More expensive

Safety of 50 amp inverter generator.

Inverter generators are convenient portable devices used as a backup power source when the pole electricity is not available. Generators may become hazardous and can harm if not used with caution. Here are a few safety measures you must follow to keep yourself and your family safe.

Electrical Hazards:

As generators require connection with your electrical wiring, they have great dangers if not handled properly. Ground your generators and add a ground fault circuit interrupter (GFCI) to ensure immediate electricity stopping if anyone is electrified.

Do not overload the generator beyond its power capacities. It will not only cause damage to your appliance, but it may also get fire. Never plug a generator into a wall outlet because it will cause back feeding and become a disaster for your neighbors and power workers.

It’s necessary to fuel the generator while it is running. It is essential to shut it down before refueling. Store the fuel in airtight containers and away from any equipment to prevent fire accidents.

Carbon Monoxide Poisoning:

Most people are unaware that portable generators emit a colorless and odorless gas called Carbon Monoxide. Carbon monoxide can be fatal if inhaled in excessive amounts or may cause sickness. Over 900 people lost their lives to carbon monoxide poisoning during the last fifteen years while operating on their portable generators, while at least 15,500 people ended up in hospital emergency rooms for treatment.

Most of these carbon monoxide poisoning incidents happened because the generators were placed indoors with insufficient ventilation. Manufacturers are now introducing the Auto shut-off feature in the new inverters. In gas build-up beyond the safe limits in the surrounding space, the sensors immediately turn off the generator.

Before buying the generator, check for the carbon monoxide safety features. You may find generators tagged with “CO Guard,” “CO Protect,” “CO Shield,” or any other similar signs.


Buying the best inverter generator for 50 Amp RV requires some wise decisions regarding the generator size, weight, noise level, and portability. Purchasing an inverter generator from leading manufacturers may seem costly at first, but they are better in durability and efficiency. The inverters manufactured by famous brands are usually updated with the latest features, making them convenient and improving their performance. A reliable generator is better than a cheaper one with low quality.
