Best 50 Amp Generator And Buying Guide

Are you considering your options for a 50 amp generator? You’ll be spoilt for choice because the market is flooded with 50-amp generators. Choosing the right generator for powering your house or for an outdoor job is a daunting task. 

When buying a generator to power your home, it’s good to choose one that produces more power than your appliances need. A small generator won’t serve you well if you have many gadgets that need power. 

Buying Guide 50 Amp Generators

 

Here are the top four factors to consider when buying the best 50 amp generator. 

  • Parallel Connection?

If you want more power than one generator can provide, you’ll have to connect two generators in parallel. Some generators can be combined this way, while others can not. 

Even though most generators can provide enough power for your fans, microwave, refrigerator, A/C, and RV A/C, plus other gadgets that you might want to plug in, in some circumstances, you may have more appliances than one generator can accommodate. If that is the case, some of the appliances and gadgets may not perform optimally, or the generator can get damaged. 

Generator manufacturers advise against using several appliances simultaneously, so if you have several appliances that need power and must run simultaneously, then you can consider buying generators with parallel connectivity capability. This can allow you to use as many gadgets as you wish. 

  • Generator Weight

The weight of a generator determines its portability. Most 50 amp generators are heavy because of their large engines. This makes them not to be as portable as the smaller generators. 

If weight is so much of your concern, you can choose the lightest 50 amp generator. Better still, there are some 50 amp generator models that have wheels you can use to move them from place to place. 

There are rare occasions that you’ll need to lift a generator, so the wheels will come in handy when you need to move your generator. Before you buy a generator, ensure its weight is okay for your needs. 

  • Noise Output

All generators produce some noise, but the level of noise varies from one generator to the next. However, most modern generators use Quiet Technology to reduce the noise they produce. Even with this technology, generators still produce noise – a generator can never be silent while in use. 

Most of these generators produce noise of between 55 – 70 decibels, which can be distracting when placed closer to the house. A generator operating at between 25 – 50% of its capacity is said to be in Eco-Mode, and, in this mode, it won’t produce much noise. 

If you operate your generator at its full capacity (100%), it will produce too much noise than what is advertised. The noise output is a crucial factor in choosing a generator because you wouldn’t want something that will keep you awake the whole night and also disturb your neighbors. Choose a generator with a noise level you are comfortable with and try to keep it as far as possible from you while in use. 

  • Fuel Type

Generators use specific fuels. Some use gas, while others use diesel or propane. We also have generators that can run on a combination of different fuels. Propane and gasoline combination is the most common with many generators because they are easier to get than diesel.

Fuels vary in their cost, so it is best to choose a generator that runs on fuel that is most affordable to you. Secondly, you can choose a generator that uses the same fuel as your RV so you can stock up the same fuel for the two machines. This can also make it easier for you to transfer fuel from one machine to another in the case of an emergency. 

Propane generators have the advantage of having a longer fuel shelf life than diesel or gas generators. However, you must consider whether you’ll have access to a dependable propane refilling station.

Frequently Asked Questions

What is the difference between 30 Amp and 50 Amp generators?

Just as the names suggest, the difference between these two types of generators lies in their outlets. The first type has a 30-ampere outlet, while the second type has a 50-ampere outlet. 

The 30A generator has three prongs on its outlet with a single hot wire of 120V. The 50A generator has four prongs on its outlet. It comprises two hot wires 120V each, and two separate 50A feeds of 120V each.  

A 30A generator operating at 120V produces 3,600 watts, while a 50A generator operating at 120V produces 12,000 watts. 

What’s the power output of a 50A generator?

Power output is calculated by multiplying the voltage by the current (Amperes). A 50A generator has two feeds of 120V each, giving a total voltage of 240V. For this reason, it can provide a maximum output of 12,000 watts (50A x 240V). However, most generators will not give this maximum wattage. 

For example, the Champion 100161 is a 50A generator, but it peaks at 9375 volts. The Duromax XP1200EH generator will start at 12,000 watts but drop to 9500 watts as it is running. 

Can I safely plug a 30A RV into a 50A plug?

The short answer is yes. But you have to remember that these two plugs are configured differently. The 30A and the 50A receptacles have three prongs and four prongs, respectively. So, you’ll have to use the 30A female and the 50A male adaptors to make this connection possible.   

Final Thoughts 

If you are seriously looking for the best 50 amp generator to buy, the above generators will be the best starting point. All these generators perform exceptionally and provide value for money. 

These generators have different features and different levels of power output, so before you settle on any one of them, check the features to ensure they suit your needs.
