Customers Reviews

There are many 50 amp generators available in the market, and each has a design for a specific function. This may easily confuse you. If you want to get the best 50 amp generator for your RV, then you should consider the factors below before making an appropriate purchase with no regrets.

  • Starting and Running watts

As we were reviewing the 6 products, we got to mention these two words a lot. All generators have running/rated watts and starting watts. The former is the endless number of watts that you need to keep your electronics running.

When some electronic devices such as refrigerators or AC startup, they need some additional power, usually high. This is what is referred to as starting watts. These are important to consider when purchasing a 50Amp generator for your RV, depending on your electronics.

  • Easily Portable

If you need to move your generator from one place to another, you will have to go for easy to carry around. First things first, it has to have a lightweight design and not too heavy. This gives you a comfortable time during operation.

Further, some have an ergonomic foldable handle that you can use to lift your generator. There are a lift bracket and never-flat wheels that help out with the more massive generators. Do not get a generator that will need you to get people to help you carry.

  • Level of Noise

It is evident that generators usually produce loud noises and vibrations and are generally annoying to both you and the third parties. However, some do not give out a lot of noise and are the most effective.

So, manufacturers have come up with features that block out noises made by the generators. Built-in spark arrestors and noise mufflers play a significant role in doing this. Those generators deliver up to 45 and 70 decibels of noise.

If the loud sound does not amuse you, you might consider getting a generator with the above factors.

  • Fuel Consumption

Fuel is what keeps your generator running. There are three types of energy that a generator uses; gasoline, propane, or diesel. It is important to note that there are generators that can operate on both propane and gasoline.

By this, we mean that in case you do not have propane, gasoline can work as a substitute. These are what we call dual fuel generators. We recommend you to get this type for convenience.

You may also consider choosing a generator that uses the same fuel as your RV. This makes it easy to refill energy when you get to a gas station and even save up as much as you can.

Propane has an extended shelf life and is usually readily available, so it is the most popular.

  • Runtime

This is how long a generator can run when operating on a half load of fuel. You will need a generator that has a longer runtime. This means that you will not have to refuel it frequently. Also, your power supply will not be interrupted for a while.

A good generator will have a runtime of over 10 hours having a full tank. Usually, run time is affected by the size of the fuel tank. An oversized fuel tank will allow more time for it to run continuously.

How Many Watts Does A 50 Amp RV Use?

A 50-amp RV uses more power and will have electronics that have high wattage needs. There are 4 AC outputs present; two 120V hot wires with ground wire, and even neutral wire.

If you want to know how much a 50amp can offer, there is a simple formula for this; volts* amperage. Because there are two AC outlets, the calculation will be as below: 2*120*50A=12,000 watts

Simply put, we multiply 120volts by the amperage, which is 50 to get a rating of 6000 watts. But remember our 50 amp RV has two hot wires. Hence, this needs us to multiply the 6000 watts by two to get 12,000 watts total voltage.

Generally, your 50 amp generator will need 12 000 watts. However, it does not justify you to get a generator with the same wattage as this will be very powerful. You will first need to consider the number of appliances you have in your RV and total kWh per device.

Usually, manufacturers recommend the best generators between 4000 and 8000 watts, which are not far from the 12,000 watts of the 50 amp RV.

How To Know If Your RV Trailer Is 30 Or 50 Amp

As an owner of an RV, you may not know whether it is 30 or 50 amps. It is essential to know this to determine the size of the generator you need or your electronic appliances' wattage needs.

The first and easiest way to know this is through looking at the plugs found on your RV. The plugs of a 50 amp RV differ from those of a 30 amp one. Therefore, if you know how to differentiate each, you will know what your RV trailer is.

A 30 amp plug usually has 3 prongs, including a 120V hot wire and even ground wire. It is meant for use on RVs that have lower requirements. On the other hand, 50 amp plug consist of four prongs; 2 120 volts hot wires, neutral wire, and a ground wire.

In addition to this, a 50 ampere RV gives out 12,000 wattages at maximum, while the 30 amp one is limited to 3,600-watts. This means it cannot go past the 3,600 wattage limit.

Besides, a 50 amp RV can run multiple electrical appliances simultaneously without any tripping happening. A microwave, air conditioner, drier, and TV can all run at the same time. A 30 amp RV can only run one appliance at a time.

In terms of outlets, a 30 amp RV does not have many of them, while a 50 amp one has various them. If you ever need to upgrade your 30 amp RV power, you need to increase the number of outlets, each of them on their circuits.

What Size Generator Do I Need For A 50 Amp RV?

Before you buy a generator for your RV, you first need to know your RV's electrical system. Is it a 30 or 50amp? We have discussed this in detail above there. Secondly, it is essential to determine the power needs of all the electronics present in your RV.

Usually, the amount of power needed by an appliance is indicated somewhere on it or its packaging. We will identify some of the most common appliances that will be found in an RV together with their wattage below.

Once you add up all the power needs of these appliances, then you will know the size of the generator to buy. A 50 amp RV needs more power as compared to the 30amp one. Hence, for a 50 amp RV, the generator will be more significant in size and power output.

It is also vital to factor in running watts and starting watts when calculating the power needs of your various appliances. To get the total power need of your refrigerator, you will need to add together its starting watts plus the running watts to get an accurate figure.

However, in a list of appliances, start by adding the running watts to the highest starting watts. We will show you an example starting with lighter appliances. Meanwhile, the minimum size of the generator for a 50amp RV should be about 4000W.

To calculate the power needs of the above, you will add together all the running watts plus the highest starting watts on the list;

1000W+ 180W+ 800W+ 400W+ 250W+ 1150W+500W+1500W=5,780W

The total wattage of these appliances will be 5780W

Because the starting watts are usually higher for most appliances, you should look out for a generator that delivers enough starting watts. Remember, we said each generator has its starting and running watts. It is also good to focus on the big appliances on your RV, such as the air conditioner.

Air conditioners usually have high kWh, and it depends on their sizes too. Choosing an RV generator largely depends on such appliances, and if you want to operate multiple appliances at once. If so, then you will need a generator that gives out more power than 4,000W.

A 15,000 BTU AC has starting watts of 3300 and running watts of 2000. This can comfortably be run by a generator of 4000W considering the starting watts. You can then run your other lighter appliances concurrently after the AC has started.

All in all, to be safe, you need to get a generator that is bigger in terms of the wattage needs of your appliances. It should have an extra 600-1000 watts more than the required. Do not get one that is too small as it will likely overload and end up not working.

If you are planning on using many appliances at once, then your generator should be between 7000-8000 watts. On the other hand, if you are operating appliances that use less power, then a generator between 4000 and 6000 watts is perfect for you.

Plugging A 50 Amp RV Into A 30amp Power Source

Can I plug my 50 amp RV into a 30 amp power source? This is a very common question that many RV users ask whenever they want to get a generator for power backup on their RV.

We notice that most RVs are 30 amps unless you need to power heavy appliances. At this juncture is when you will consider a 50 amp generator. To answer this question, yes, it is possible to power your 50 amp RV using a 30 amp source of power using an adapter.

However, it may not power it up efficiently. As we know, the total wattage from a 30 amp generator is likely to be 3,600 at maximum. So if the appliances in your 50 amp RV have a rating of 10,000 watts, the power source will not be able to provide sufficient power.

Connecting to a 30 amp power source largely limits you the number of appliances to use in your 50amp RV. If you click high wattage appliances, the circuit breakers are likely to trip, and this is not what you want to achieve.

For high performance, you will need to connect the appliances one by one. The dog bone electrical adapter is the most recommended adapter that connects a 30 amp power source to a 50 amp RV.

Nonetheless, experts do not recommend this type of connection. You are either using a 50 amp generator with a power source of the same wattage or just use a 30 amp one.

Best Ways To Maintain Your 50 Amp Generator

You should never expose your generator to harsh weather conditions such as rain and snow, as it is hazardous. If the engine and wiring get exposed, there will be lots of damages. Also, you would not want to risk electrocution due to the outlet panel’s exposure to water.

To avoid this, you can come up with an outdoor structure to shelter your generator. This can either be temporary or permanent, depending on how you want. But usually, we recommend a rigid and durable permanent structure for efficient results.

It is also important to occasionally lubricate it with regards to the manufacturer’s recommendations. Be sure to change the engine’s oil. If you use stale oil that has overstayed, it may cause damages to your generator.

After every use and before storage, make sure to drain fuel from the generator carefully. This is when you do not intend to use the generator as soon and want to store it away for a while.

Procure professional servicing for your generator regularly. This may be costly, but well, it will be worth it. You would not want to spend more monies on repairs and replacing the different parts of the generator.

Reasons Why Generator Will Not Start

We have seen customers complaining severally about their generators not starting. Therefore, we outline below some of the common reasons why your generator does not start.

  • Your generator may be low on fuel. The first thing to do before operating your 50 amp generator is to check that the fuel tank is not empty. Also, check that the tubing and the valves on the tank are open.
  • Engine does not have oil. The generator’s engine needs oil to run, so the fat is low for as long as it will not start. Not changing your oil in more than 50 or 20 hours may cause this or any leakage.
  • Dead batteries may cause your generator not to start. If you are using an electric starter to start up your generator, check whether the starter’s battery is dead. If this is the case, try using another method of starting it up or jump-start the battery using your car’s battery.
  • There should be no cables plugged on to your generator’s outlets when you want to start it, as this will prevent it from creating.
  • Having too much air or too little of it, mixing with fuel during combustion will cause the generator not to start. Besides, your air filter may be blocked with dust particles, and debris prevents enough air combustion in your carburetor.
  • When the generator’s carburetor blocks, your generator will fail to start. This is due to old gasoline or propane clogging, thus preventing the new fuel from penetrating. To avoid this, you have to clean the carburetor.
  • Low oil sensor may be malfunctioning, and thus your generator will not start.
