There are a few generators on the market that use propane as fuel. You can also get conversion kits to convert your gasoline generator to run on propane or natural gas. Propane being much easier to store and more stable than gasoline many people are opting to use it as fuel for their generators. When you use propane as fuel for your generator you will need to find the right size of tank that will suit your needs.
Most Portable LP Tank Sizes
Propane tanks come in different sizes and they can all be adapted to use with your generator. The most common size tank that is used with portable generators is the 20 lb grill size tank such as the Worthington 303955 20-Pound Steel Propane Cylinder. This holds about 4.7 gallons of propane and is portable allowing the generator to be used anywhere it is needed.
The reason that most generator users like to use the 20 lb tank is that these tanks can be just swapped for fresh ones at most gas stations. You do not have to have them refilled which makes them very convenient to use besides they are light enough to be portable.
Portable propane tanks are also available in 30 lb and 40 lb tanks, these hold 7 gallons and 10 gallons of propane respectively.
Stationary LP Tank Sizes
If you do not need to move your generator you could also connect it to larger tanks which would give you a longer run time. You could connect it to a 100 lb tank or even larger tanks. Since propane is often used for heating in a home it is usually stored in 57 gallon, 120 gallon, 500 gallon or 1000 gallon tanks.
Adapters and hoses are available whereby you can connect your generator to these household tanks to ensure uninterrupted electric power during power outages. Standby generators are usually connected to these tanks that supply the household with propane.
Run Time with LP Tanks
When you consider the size of propane tank that you would like to attach to your generator, you should be aware that the rule of the thumb is that a 1500 to 1600 watt generator will run for about 10 hours on a 20 lb propane tank while a 3000 watt generator will run for about 7 to 8 hours on the 20 lb tank.
Special Application LP Tanks
Worthington makes propane tanks in many different sizes for different applications, one of the sizes of tanks that they make is a 1 gallon tank. Worthington 281149 1-Gallon Steel Propane Cylinder.
This size of a propane tank is very portable and can also be used with your portable generator. Since it is only 1 gallon in size this tank is mainly used for special applications with a generator where either the size of the tank is important or if you need to use the generator for a short period of time.
Here are a couple of other small LP tanks worth considering for those quick and dirty jobs.
