What Is A 5000-Watt Generator?

A 5000-watt generator provides you with backup power when there is a power outage or provides power when camping.

Having a 5000-watt generator gives you the ability to run the heating/cooling system of your house, power appliances, and keep the lights on in your house.

5kW generators are typically suitable for small to medium sized houses as well as RVs. These portable generators will be able to run a couple large appliances and several smaller appliances at the same time.

A 5kW portable generator will typically last around 15-30-hours when running on gasoline. A propane-fueled generator will run a little less at 10 to 25-hours.

How Do Portable 5kW Generators Work?

Simply put, a portable generator takes mechanical power produced from a fuel-powered engine and converts it into electrical power. 

The engine of the generator turns on the alternator and produces electricity. The more powerful the engine, the more electricity it is capable of producing.

What Are The Different Types of 5,000W Generators For Houses?

There are three different types of fuel that portable generators are powered by: gasoline, propane, and diesel.  Each has their advantages and disadvantages. 

Propane

Propane generators are well suited for use as residential back up power. 

Pros

  • No expiring shelf life so it won't go bad
  • Enclosed canister so it has no risk of spilling
  • Does not produce carbon monoxide
  • Many homeowners already have a canister so there wouldn't be another fuel canister laying around
  • Longer run time 
  • Quieter 
  • Little maintenance

Cons

  • Shorter life span
  • More expensive up-front cost
  • Can be difficult to find propane in some areas 
  • Must carry propane tank with the generator 

Diesel

Diesel generators are good if you need constant power with an automatic transfer.

Pros

  • Reliable
  • Long lasting 
  • Highly efficient even with little load
  • Has zero radio frequency emissions
  • Less maintenance than gas powered equipment

Cons

  • Loud
  • More costly repairs and maintenance
  • Not clean energy fuel
  • Expensive 

Gasoline

Gasoline generators are the most common type of portable generator that is used for power outages or even just camping.

Pros

  • Lower up-front cost
  • Fuel readily available
  • Quieter than diesel generators
  • Cleaner energy than diesel 
  • Smaller Size 

Cons

  • Creates carbon monoxide
  • Degrades/evaporates over time
  • Flammable 
  • Requires regular maintenance

Size

Generators come in so many sizes in terms of wattage.  Depending on how many watts of power you are looking to run determines the wattage generator you will need. As the wattage goes up so does the physical size of the unit.  

Portability

Depending on your application, portability of the generator can be important.

Some come already on wheels and have handles that make it very easy to move. This is a big plus as some of the generators can be very heavy.  

Others you have to purchase a portability kit separately and install the wheels and handles yourself. 

If you have a place the generator will always sit, portability is not that big of an issue.

Starting Capabilities

There are two ways a portable generator is able to be started: electric start or recoil start. Some have both, others only have one or the other so make sure to double check how the generator is able to be started.

Electric Start

Electric start is great if you are unable to pull a recoil.  With just the push of the button to start it, almost anyone is able to start the generator.  

A downside is that it requires a battery to start.  This can cause issues if the battery is dead, and you need to use the generator.  

Recoil Start

Recoil is reliable because it doesn't require a battery to start the generator. You just have to be able to be strong enough to pull the recoil. 

The downside is the compression on some generators can make it very difficult to pull.  This makes is hard for anyone without enough strength or limited mobility to be able to start the generator.

How To Pick The Best 5,000-Watt Electric Generator?

There are some key factors when picking a generator for your home. When the power goes out, how many appliances and lighting circuits are you going to want to try and run? This will decide the size of generator you will need.

The degree of portability is not to be forgotten; the weight of generators and whether they come with a portability kit installed already varies greatly between brands and power capacity.

Generator Capacity 

Generators are sized to the number of watts that you intend on drawing.  

To pick the best generator for your needs, get a list of everything you would like to run, and calculate what your highest amp draw will be.  You will not want a generator smaller than that calculation.

Most appliances will have their watt draw listed on the informational label that has the model number on it.  

If it doesn't have the number of watts listed but has the amperage and voltage listed, you multiply the number of amps times the voltage it runs at.

Safety Features 

Safety is important so there are a couple things you should look for when choosing a generator.  It is best to have one that has built-in safety features to prevent carbon monoxide poisoning or running with low oil.  

low oil gauge is a good addition to your generator because if it gets low on oil without you knowing it could cause catastrophic damage to your generator.  

A carbon monoxide monitor is a great safety feature as well.  The toxic emissions produced by gas and diesel engines can be deadly, so if you can get a generator that will shut down at the sign of carbon monoxide it can be a great feature to keep your family safe. 

voltage meter is very beneficial because it will show you what voltage the generator is putting out.  This can help protect your appliances by ensuring that they are receiving the proper voltage.

An hour meter is a good feature to have to help keep track of when maintenance is due according to the number of hours the generator has run.

Outlet covers are great additions to your generator especially when sitting out in the weather.  This helps prevent moisture from getting into the outlets while they are not in use creating problems.

What Are The Risks of Using A 5kW Generator?

Anytime you use any kind of electrical equipment electrical shock or electrocution is a hazard.  You need to be familiar with how generators work and how to operate them before doing anything. 

Running the generator in a non-ventilated area can cause a buildup of carbon monoxide which is known as the silent killer. 

Overloading your generator can damage your generator or anything plugged into it.  It can also create the potential to cause a fire from the heat created from overloading.

Final Thoughts

Going without power is never fun, so it is a great idea to have a generator on hand that you can fire up during power outages.  

Every generator has its advantages and disadvantages, so you need to decide what is important for you to have on your unit.  Decide how much wattage you will require and find a generator that will fit your needs!
