This generator is one of the most popular generators worldwide. It can provide safe and reliable backup power so that you can keep all your appliances and devices protected without risk.

What is Propane?

Propane is the liquefied petroleum gas (LPG) that is used as fuel to run different fuel-powered appliances and devices such as generators or inverters. This gas is colorless, non-toxic, and has no odor. It’s the best eco-friendly and engine-friendly fuel. 

How Do Propane Generators Work?

A propane generator works through the burning of propane gas. During the burning time, it creates heat and energy. This energy or motorized power is then converted into electrical power. Below are some of the components that help a propane generator produce electricity to provide backup power: 

  • Internal combustion engine
  • Alternator
  • Starter
  • Fuel tank
  • Outlets

What Are the Advantages to Propane vs Gas?

It’s widely accepted that propane is safer and cheaper gas compared to gasoline. If you use propane for your generator, your generator engine will last longer and perform better. If you use gas, you will get more power, but your generator engine will not last long and perform better like propane. Below are some of the advantages of propane:

1. Prolongs the Engine Life:

Propane is a beneficial fuel that heats the generator engine quickly even when the engine is cold. It’s good for both the fuel tank and the engine. The burning mechanism of propane ensures the extended life of your generator engine. 

2. Offers clean and environmental-friendly Burning:

Propane is a clean-burning fuel that produces less carbon monoxide than other fuels. It also produces fewer toxins. At the same time, it doesn’t emit greenhouse gas, so it helps to keep our environment safe and clean. 

3. Can easily be stored in both larger or smaller Tanks or Cylinders:

You can easily store propane for up to 30 years in both your larger or smaller tanks or cylinders. It also doesn’t have a shelf life, so you can use this fuel without any issue as long as it lasts.  

4. Available during Power Outages:

Since you can store propane fuel for a longer time, you can get it anywhere if there is a power outage. Storing propane fuel is also safe as propane tanks are extremely durable and very hard to explode or fall into any issue. 

5. Less Emission Compliant:

Though most of the fuels produce greenhouse gas or carbon monoxide, propane doesn’t emit such things. That means using propane is not only safe for the engine but also for the environment.

6. Provides quiet Operation:

Propane-powered generators or engines are very popular and widely accepted because of its quiet operation capability. Compared to other fuels, it produces fewer decibels as well as less noise. 

Frequently Asked Questions

In this section, we have provided some answers to your frequently asked questions to better assist with your generator buying needs. 

✅ Are Propane Generators any good?

If you consider the convenient use of a generator, then propane generators will be one of the best choices. Apart from that, a propane generator is better for both the environment and the generator itself.

✅ Is it cheaper to run a Generator on Propane?

Yes. It’s cheaper to run a generator using propane fuel, especially if you live in a place where the price of propane is less. However, the cost of the propane is almost half the price of gasoline.

✅ How long will a 20 lb Propane Tank run a Generator?

The time will vary depending on the load you are using and the type of generator you have. However, with 20 lb propane, a 5000 watts generator with the engine power of 10 HP can probably run for up to 8-10 hours on 50% load capacity.

✅ Are Propane Generators quieter than Gas Generators?

Yes. A propane generator is not only quiet but also more environment-friendly compared to a gas generator.

✅ How long will a 500 gallon Propane Tank run a Generator?

This will vary depending on the generator and the load amount. However, a 5000 watts generator with the engine power of 10 HP can probably run for up to 20-250 hours on 50% load capacity.
