Best 5000 Watts Inverter Generator Buyer’s  Guide

Now that you are in the market for a 5000-watt generator, you need to know aspects and options suitable for your power requirements.

Every generator model in this review has been designed to fit a specific set of consumer requirements.

Therefore, it is essential to do proper research before investing in any of the 5000-watt generator models in the market. Here is what you need to consider.

1. Type of generator

Are you interested in a conventional or an inverter generator? The critical difference between the two is their mode of power production. It is good to also understand how does an inverter generator work?

Conventional generators only produce AC power which is directly used to run different electronics. On the other hand, inverter generators produce power in three phases: they convert the high-frequency AC power produced by the generator into DC power which is then converted into stable AC power.

The final AC power produced by the inverter generator is free from spikes and distortion; this explains why it is called clean power.

The power produced by an inverter generator is safe for powering your delicate electronics, including personal computers, smartphones, and sounds systems.

On the other hand, powering these electronics with a conventional generator could be risking them because of the power variations from them.

An inverter generator is less noisy than a conventional generator and more expensive than a conventional one. While conventional generators are cheaper compared to inverter generator, conventional generators are bulky, heavy, and noisy.

If you are looking for a 5000watt generator for powering your power tools at a construction site, a conventional generator is ideal. However, if you will be using it for camping or at home, an inverter generator is ideal.

2. Fuel Source

There are three familiar fuel sources of generators: propane, gasoline, and diesel. Diesel is mostly for commercial power demands because they are large and noisy.

Most 5000-watt generators run on gasoline. This is because a 5000-watt generator needs a lot of driving force to deliver such power outputs.

You can also come across a dual fuel 5000-watt generator. Such units allow you to switch from either propane to gasoline or vice versa.

You have the freedom to choose your fuel source based on the availability, running time, and cost of that fuel.

However, when using propane, you will have to lug around with a propane tank and the generator; this could need a lot of space, especially when you are an RV reveler. Gasoline-powered generators have an in-built tank for gasoline.

Your fuel choice should be affordable and readily available in the area you will be using the generator.

3. Fuel Tank Capacity

The fuel tank capacity of your preferred generator will directly influence its running time. A 5000-watt generator with a big fuel tank of like 6 gallons will run for long hours compared to one with a small tank of about 2 gallons.

However, the fuel efficiency aspect will also come into play. If you will be using the generator regularly and for long hours, you should go for a fuel-efficient unit with a bigger fuel tank capacity.

On the other hand, if you are not a regular user of the generator and only run it for short periods, then a generator with a small tank could be okay with you. In both cases, fuel efficiency depending on the load is paramount.

4. Available Power Outlets

The versatility of a generator will depend on the number and types of outlets in its power panel. If you are an RV reveler, you need an RV Ready generator, and it should have an RV ready twist receptacle.

Similarly, if you will be using it as your emergency power backup plan, it should have a 120/240V 30A outlet, transfer switch ready for easy connection to your home’s breaker box.

A 120V 20A outlet is also ideal for powering household appliances. In some instances, you can also find a generator with USB outlets, which is for adding the convenience of recharging your portable devices.

Ensure the generator of your choice has the right outlets for powering your appliances.

5. Noise Ratings

If you plan to use the generator in your estate or camping ground, you have to be careful about the rated noise of your preferred option. Your neighbors are not interested in hearing your generator chugging away while trying to catch a nap or watch their favorite TV shows.

Don’t be a bother to your friends. Noisy generators are also not ideal for camping and RVing, and most natural parks have a restricted noise level. However, if you will be using the generator for outdoor activities in an open area such as a construction site, the noise level may not be an issue.

Noise level is rated in decibels (dB). A large number of the 5000-watt generators in the market today and in our review have a rated noise of 68 decibels which is average. In most cases, the noise level is worked out from the range of 21 feet. The further the generator is placed, the lower the noise level.

If noise is a big factor to you, check on the noise rating before ordering for your power generator.

6. Warranty

Buying a 5000-watt generator is a heavy investment. To get the value for your money, you need a generator that will serve you flawlessly for many years.

A quality generator brand will come from a renowned manufacturer who will give you a more extended warranty period. Manufacturers who trust the quality of their products will not give you less than two years warranty period on service and parts of the generator.

You must read and understand the warrant information before ordering your unit. It is because warrant terms differ from one manufacturer to another.

For instance, there is a limited warranty that solely applies to certain parts of the generator or specific types of defects. This means that the manufacturer is picky about what the warrant covers.

Safety Tips and Precautions to Observe When Using a Generator

Depending on the size of your generator, it can power all your electricity needs and make your life seamless. However, if care is not taken when using this equipment, it can be disastrous. Here are safety tips to observe.

  • Regardless of the size of the generator, do not operate indoors, near your vent, windows, or doors. Place it around 15 feet away from your house. This is to avoid the entrance of the poisonous carbon monoxide gas into your house.
  • Ensure your generator is running before you plug your appliances. It is also essential to plug one appliance at a time to ensure there is no overload.
