Best RV Generator

When you head out in your motorhome, you’ll want all the creature comforts of home when you stop to camp and for this, you’ll need a source of power. Most campgrounds have “shore power” or outlets for AC power so you can connect your RV and enjoy your favorite television or radio shows.

However, if you decide to head off the grid into the backcountry far from the maddening crowds, or if you get to a campground and all the AC outlets are taken, you are going to need an additional source of power.

Depending on the size of your motorhome and the number of people traveling with you, additional sources of power can include battery chargers, extra battery packs, or solar panels. A generator is another excellent source of power that will provide enough power for a large RV carrying several people.

If you decide to head off the grid into the backcountry, you are going to need an additional course of power in the form of a generator.

So, what are the best portable generators for RVs, campervans, and motorhomes?

Things to Consider When Buying an RV Generator

There are several factors to consider when buying a generator for your RV such as how much power is required for the motorhome and its accessories like lights, air-conditioning and heating, entertainment systems, and coffee machines, etc.

Other factors to think about are where and how the generator will be stored while traveling, the availability of fuel for the generator, whether it makes a noise, and the carbon footprint it leaves on the environment. And, of course, the cost.

1. Type of Generator: Conventional vs. Inverter Generator

There are two types of generators: conventional and inverters. A conventional generator runs on a simple engine at a regular speed, while inverter generators operate with a microprocessor that regulates and monitors a current. This current changes the throttle on the engine to produce power specifically for the load carried.

The simple electronics in conventional generators can be sensitive to surges, which can cause them to short, so most RV generators are inverters. Inverter generators are also far more fuel-efficient than conventional generators.

Inverter generators operate with a microprocessor that regulates and monitors the current.

2. Power Output

The second most important consideration to make when shopping for a generator for your RV is that of power output. The generator will need to produce enough power to cover all your appliances. Devices such as air conditioners and microwaves require a lot of power so if you want to run them regularly, make sure your generator has a high enough wattage output to handle it.

3. Maneuverability: Portable vs. Permanent

Permanent generators can be installed directly into the RV and connected to an onboard fuel source or backup RV battery. Portable generators are less expensive and are great for camping, tailgating, or using in your home.

4. Noise Emission

Noise is another important consideration to make when shopping around for a generator. If you plan on spending a lot of time in campsites, you’ll want a generator that makes minimal noise. Most national parks have regulations on the amount of noise they are willing to tolerate from generators.

5. Fuel Consumption

Obviously, the higher the load on the generator, the more fuel it will use, so you’ll want to get a generator with good fuel consumption.

What Type of Fuel Is Best for Recreational Vehicle Generators?

Generators can operate on three types of fuel: diesel, gas, and propane, all of which have pros and cons.

Diesel – Diesel is very efficient and burns cleanly, meaning a diesel generator will produce more power per tank than a petrol one and leave less of a carbon footprint. However, they can be very noisy and smelly, so are not a popular choice.

Gas – Gas generators are one of the more popular choices for use in RVs. While they are common, gas can be expensive, however, many generators have a dual fuel option that runs off gas and propane.

Propane – Propane is becoming more popular as an option for fuel as it is very efficient and less expensive than gas.

Overall, our recommendation is to either get a permanent Cummins Onan RV generator (which is made specifically for RVs) or to grab the Honda EU3000i or Champion 3400-Watt Dual-Fuel generator if you prefer something portable.

Tips to Care for Your New Generator

A generator is a costly investment, and you will want it to last a lifetime – or as long as possible! Here are a few tips for caring for your generator to keep it in tip-top shape for years.

1. Correct Storage

Generator engines need to be kept dry and away from moisture and wet weather, which can cause damage. It is important to store your generator in a dry place to prevent water damage. Before storing your generator for the winter, be sure to wipe down the exterior, fill the full tank, add a fuel stabilizer and run it a while to work the stabilized fuel through the system, and change the oil/oil filter. You can also drain the fuel and lines before winter storage.

2. Regular Services

It is important to service your generator regularly to ensure a long lifespan. Regular services will clear clogged fuel lines and keep general engine wear and tear at bay.

3. Run the Gene Regularly

To keep your generator in good shape, you need to run your generator at least once a month. This not only guarantees proper function, but it also helps to find out whether any issues may become a problem in the future.

4. Always Use New Fuel

One of the most important factors for maintaining the longevity of your generator is never to use old fuel as this can create a build-up in the engine that can decrease the performance. For best results, always keep your generator filled with fresh fuel. Another way to do this is through fuel cycling.

5. Lubricate Regularly

A generator works best when it is well-oiled, particularly if the generator is gas-powered. Your generator must be adequately lubricated at all times as this not only ensures optimum operation but also promises lower noise levels. It is also important to perform oil and filter changes at least every six months, much like your car.

6. Keep Batteries Clean

Just like the engine of your car, you should make sure that the battery lines are always kept clean. It also helps to disconnect the batteries and the battery lines while your unit is not in use.

Frequently Asked Questions

What type of generator is best for an RV?

Diesel generators are your best bet if your RV runs on diesel fuel as this allows you to use a single fuel source for both your generator and your camper. The best diesel generator for RVs also produces more power than propane and is safer to store because it’s non-explosive.

What size generator do I need for an RV?

You will need a generator that produces between 2,000 and 4,000 watts as most RV generators put out between 2,000 and 4,000 watts of electricity.

What is the quietest generator for a motorhome?

The quietest generator on the market is the gas-powered Honda Inverter Generator EU2200i. Weighing less than 47 pounds, this quiet RV generator can be easily moved from place to place.

What size generator do I need for a 30-amp RV?

A 3,000-watt generator will power most 30-amp RVs, including the AC unit.

What Size RV Generator to Run Air-Conditioning Units?

Air-conditioning requires a large amount of power and can run at anything up to 2,000 watts. If you have an air-conditioning unit and want to run it off-grid, you’ll need a powerful generator or at least 3,500 watts.

How Do I Charge the 12-volt Battery Bank from the Generator?

If your camper is fitted with a battery converter (or battery charger), it will continue to operate in the same way without any adaptations. You can charge a 12-volt battery bank with the same extension cord that you use to connect your RV to the generator. If your cord isn’t compatible, you can use an adaptor.

Do I Need to Ground a Portable RV Generator?

In short, yes! NEVER use a portable generator unless it’s grounded.

Happy traveling!
