Buying Guide

For most buyers, it is never enough to just look at generator and buy it. We often look deeper into the features that such a generator has to offer. Besides describing the top best 3000-watt RV generators above, we have taken a step further to look into the factors and the features that a buyer should look into whenever they wish to buy one. We have further answered a few FAQs to help you pick the most appropriate RV generator to use with your RV.

3000-watt generator – what to use them for?

7 Great 3000-Watt Generators - Efficient Power Source at Hand

The first question many people ask themselves before they invest in a generator is how big the generator should be. It is also important to ask yourself how many watts are needed to power the various appliances and devices in your possession. For a person looking to power their entire home, a 10,000-watt generator would be ideal. However, for an RV owner, a 3000-watt generator more often than not proves to be perfect.

A 3000-watt inverter generator should power any appliance in your RV, including a fridge, AC, TV and lighting circuits. You can also use this generator to power some sensitive devices such as laptops and phones. They produce a current that is not fluctuating hence making it safer for these power-fluctuation sensitive devices.

The first thing to do is to calculate the total wattage that such a generator produces. Remember to factor in the starting watts and the running watts of each appliance.

 

How to use 3000-watt generators

Every 3000-watt generator should come with a user manual to help you set it up. The manual also helps you when you are doing regular maintenance of the generator. As is often the case, generators do not come filled with oil or gas. These are some of the vital but basic skills you should familiarize yourself with.

Whenever you buy a high-quality 3000-watt generator such as the Honda EB3000C, check the type of oil the manufacturer has recommended. In many instances, it is 10W-30.

  • Using the dipstick provided, put in some oil while ensuring that you don’t overflow the oil tank.
  • Fill the fuel tank with gas. You can put a fair amount of gas if you are simply testing the generator.
  • When it comes to starting the generator, first turn on the generator then confirm that the choke is on ‘choke’ position. Put the gas lever on the ‘flow’ position. Yank/ pull the pulley to start the generator. Sometimes, it might take you more than one pulls to get it started.
  • When the engine starts, put the choke lever in the ‘unchoke’ position. To make sure the gas line is clear, turn off the gas flow lever. This will make the generator use all the gas in the system and help make the whole system clear and unblocked.

 

Safety advice for generator users

7 Great 3000-Watt Generators - Efficient Power Source at Hand

Generators do come in handy when there is power disruption or when you want to have power and are away from the main grid. While such a machine is known to offer great benefits, they are also known for causing severe body injuries, death and property damage. It is therefore imperative that you know some of the precautions to take when you are using a generator. Here are the tips;

  1. Always operate a generator at least 15 feet away from your residence. The exhaust or the back part of the generator should be facing away from where you are. It is generally recommended that you operate the generator outdoors or in a well-ventilated area. Never run a generator in your basement or garage.
  2. Turn the generator ON before plugging in your appliances. This helps at avoiding overloading the generator.
  3. To avoid electrical shocks, never touch your generator with wet hands. Keep and operate your generator in dry covered spaces. Avoid placing it in water puddles.
  4. Before fueling the generator, make sure that it is off and cool.
  5. To avoid back feed, never plug the generator to the wall. Always use heavy-duty extension cords to power your appliances.
  6. Children and pets should be kept away from a generator, especially when it is running.

Price range

Like is the case with most products and services out there, price is a determining factor when you want to buy an RV generator. If you are cash-constrained and you really need a generator, then the Generac 7129 GP3000i and Firman W03082 will cost you less than $1,000. On the other hand, for those with deeper pockets or looking for very specific features, then Honda EB3000C and Honda EU3000IS1A will cost you at least $1,000. But in picking the best 3000-watt RV generator, essential factors such as noise level and the number of gadgets it can power often come ahead of the price.

Consider the following features before purchasing the best 3000-watt generator

Every generator is different from the other, even different models from the same manufacturer. That said, each generator is designed and made bearing some specific features that make it unique. While some can be used around the house, others are specifically designed to be used with RVs. When shopping for your RV generator, it will help you a great deal if you explore the various features that it comes bearing. Here are some of the must check out features.

Should it be an inverter model?

7 Great 3000-Watt Generators - Efficient Power Source at Hand

An RV owner is generally someone who loves the outdoors and activities such as camping. This would then mean that the generator they should invest in is one which is portable, quiet and powerful. An inverter generator such as Honda EU3000IS1A or the Generac 7129 GP3000i are some of the best ones to consider. The benefits of using an inverter generator are that it is lighter than contractor generators. They are smaller and quite portable. The level of noise produced by an RV generator is a significant factor since you will often find yourself in serene locations where noise can be a big nuisance. Moreover, an inverter generator produces clean power which is compatible with your Smartphone and other sensitive electronics.

Fuel tank and efficiency

The amount of fuel a generator can hold determines the number of times you will need to come out and refill the tank. Some generators don’t require any refill the whole night while some will require three or even more refills in a single night.

As for the generator’s efficiency, you should check how much the unit is consuming so as to power your appliances or to produce a certain number of watts. While a good 3000-watt RV generator can power your RV’s AC, different generators will consume different amounts of fuel to do the same task. A generator with higher CC rating should be more efficient because it is producing more power.

Running time

Another thing to note is that a generator on 25% load will use much less gas than when it is operating at full load. Like in the case of the Honda EU3000IS1A generator, it has a 3.4 gallons fuel tank which enables the engine to run for up to 20 hours when on a ¼ load. When it is put on a full load, it will last for 7.2 hours which is still impressive. While a large tank typically means longer spans of refueling, that is not always the case. Find an RV generator that consumes lesser fuel for more extended periods at higher loads.

Noise levels

The lower the decibels your RV generator produces, the better it is presumed to be. The reason for this is because more often than not, you will find yourself going camping where there will be other campers. If all the camper’s generators are loud, you can imagine how chaotic such a place will be. RV generators will produce anything around 60dBA; if lower, the better. In the case of WEN 56352, which makes 67dBA, it is louder or noisier than the Briggs & Stratton P3000 generator which produces 58dBA.

Outlets

7 Great 3000-Watt Generators - Efficient Power Source at Hand

It goes without saying that the more the power outlets a generator has, the better it is for the user. However, such ports should only be able to handle the power a generator produces. You don’t want to have a single outlet yet you have five appliances that require to be connected. RV generators offer outlets such as transfer ports, household ports and USB ports from where you can connect and power your devices. The more the varieties of ports your generator has to offer, the more practical and useful such a generator is to you.

Guarantee

A generator backed with a guarantee makes it a better bargain because if it malfunctions or breaks down, the manufacturer has given their word to replace or repair it. All the credible manufactures of RV generators back their products with a warranty. Having been in the industry for many years, and having produced trusted generators, manufacturers can dare back their products with lengthy guarantees today. Firman, Honda and Generac back their generators with a 3-year warranty while Briggs and Stratton back theirs with a 2-year warranty.

Safety and durability

A generator that is not safe to use will pose many dangers to you, others and the environment. A generator should come with a spark arrester which helps prevent a forest fire. Still, manufacturers have clearly indicated which parts of the generator you should not to touch to avoid injury. As for durability, you will find a user manual which should help you maintain and service the device with ease. A manufacturer should use handy materials to increase the life of your generator.

Portability

The whole idea of an RV generator is to allow you to transport it to whatever locale you are going with your RV. This being the case, such a generator should be easy to carry around. After all, it is the source of power for your home on wheels. A good RV generator should therefore come with wheels and handles that allow you to transport it with ease. In the case of Firman W03082, the manufacturer has used 5.5-inch wheels, and in Briggs & Stratton P3000, the wheels used are 6 inches.

Extra features

To beat the competition, manufacturers strive to add extra features in their products. A basic RV generator will have two or three standard power outlets, but some manufacturers like Firman and Generac have found the need to include USB ports which can be used to charge a smartphone. The Yamaha EF3000iSEB generator comes with a Boost Control Unit (BCU) which senses when you need extra power and adjusts itself accordingly. Low-oil detection has become an almost standard feature now in all RV generators. Honda EU3000IS1A generator comes with an electric start while WEN 56352 offers LED indicators.

FAQ

The 3000-watt rating on a generator means the maximum watts that can be used at any specific moment should be 3000 watts at a particular voltage. This then means that while it is possible to plug in more appliances, the output voltage will lower, and this would then mean the appliances are operating at lower than optimal voltage capacity. While some appliances will operate alright, many will malfunction or even get damaged.

Some appliances such as the fridge and freezer or washing AC will be operating intermittently. But rarely will you ever find yourself needing to use the blender, the toaster, the coffee maker, and iron all at the same time. You will therefore find that a 3000 watts generator can support normal usage of all household appliances. Just take note of the watts and voltage indicated on each item to avoid overloading the generator or damaging your stuff.

Every generator uses a specific kind of fuel. There are diesel generators, and there are those that use gasoline. In the case of a 3000-watt generator, low octane gasoline is recommended even though high-octane gasoline will work just as well. The reason why low octane gasoline is recommended is to prevent the engine of the generator from ‘knocking’.

To get the best value out of your generator, you will need to take a few steps to maintain it. While it is possible to have a well-running generator for decades, remember that it is how you treat that will determine its longevity and how optimally it will be serving you.

  1. The first thing to do is to invest in a warranty backed generator. This makes it easier to maintain and repair your generator.
  2. The second thing to do is invest in a cover which helps prevent the generator from getting wet from the rain and also from dirt.
  3. To prevent premature burn-out, invest in heavy-duty cords to help lower the voltage. To avoid surprises, power up your generator every three months for about 30 minutes. This will help charge the electric starter.
  4. Invest in filters. Whenever the servicing of the generator comes due, you don’t want to run all over town. Such filters will also help you avoid being tempted to postpone the servicing of the machine.
  5. Lastly, avoid empty fuel tanks. Whenever a generator runs out of fuel, the electrical load of the connected appliances sucks the magnetic field from it.

Our Verdict

We picked the Yamaha EF3000iSEB generator as the editor’s choice. This generator stands out from the rest mainly because it comes with a starting wattage of 3500 watts and a running wattage of 2800 watts. Besides having the cool BCU feature, the generator is surprisingly quiet. It is powerful and will run overnight without the need to refuel.

The Honda EU3000IS1A generator is the best 3000-watt generator in the market today. This Japanese machine reaches a peak wattage of 3000. It is very quiet at only 57dBA. It will run for up to 20 hours without the need for refueling. It is our second choice because it is durable and is backed by a 3-year warranty.
