Propane is a popular fuel source used for powering a wide range of applications, including generators. It is a clean-burning fuel that is readily available in most locations, making it an excellent choice for those looking for a reliable source of backup power. However, one of the most commonly asked questions among propane generator owners is how long will a 250-gallon propane tank last when running a generator?
The answer to this question depends on a range of factors, including the size of the generator, the power output required, the load capacity of the propane tank, and the efficiency of the generator itself. In most cases, a 250-gallon propane tank will provide enough fuel to run a generator for several days, if not weeks or months!
To understand how long a 250-gallon propane tank will last when powering a generator, we need to first understand the basics of propane tanks and generator fuel consumption. Propane tanks are designed to store liquid propane at high pressure, which is then drawn out as a gas as needed. The size of the tank determines the amount of propane it can hold, and this directly affects how long it will last when used to power a generator.
On the other hand, the fuel consumption of a generator is measured in gallons per hour (GPH) or pounds per hour (PPH). The fuel consumption varies depending on the size of the generator and the load capacity it is powering. For example, a small 5-kilowatt generator will consume around 0.75 GPH of propane when running at full load, while a larger 20-kilowatt generator will consume around 3 GPH of propane under the same conditions.
To calculate the runtime of a generator when powered by a 250-gallon propane tank, we need to know the generator’s fuel consumption rate and the size of the tank. For instance, a 20-kilowatt generator will consume around 3 GPH of propane when running at full load. A 250-gallon propane tank will provide around 600 pounds of propane, which is equivalent to 144 gallons of propane. Therefore, a 250-gallon propane tank should last approximately 48 hours (144/3) when powering a 20-kilowatt generator at full load.
However, it is important to note that most generators do not run at full load all the time. The generator’s power output varies depending on the demand placed on it. Therefore, the actual runtime of a generator when powered by a 250-gallon propane tank will vary depending on how the generator is being used. For example, a generator running at 50% load will consume half as much fuel as the same generator running at full load.
In conclusion, a 250-gallon propane tank is an excellent choice for powering a generator for several days, if not weeks or months. However, the exact runtime will depend on a range of factors, including the size of the generator, the load capacity and efficiency of the propane tank, and the generator’s fuel consumption rate. Therefore, it’s always best to consult with an expert to determine the exact runtime you can expect from your generator when powered by a 250-gallon propane tank.

Frequently Asked Questions
1. How long will a 250-gallon propane tank run a generator in hours?
The answer to this question depends on the generator’s fuel consumption, or in other words, how many gallons of propane it uses per hour. We cannot provide an exact answer, but on average, a generator running on propane can consume about 2-3 gallons per hour. So, a 250-gallon propane tank can run a generator for about 83 to 125 hours.
2. Can I use a 250-gallon propane tank to power any generator?
Yes, you can use a 250-gallon propane tank to power most generators that run on propane. However, it is important to check the generator’s fuel consumption rate and the maximum capacity of the propane tank before connecting them. Make sure that the propane tank has the correct fittings and pressure rating for the generator you intend to use.
3. Is it more cost-effective to run a generator on propane than gasoline or diesel?
Yes, running a generator on propane is generally more cost-effective than gasoline or diesel as propane is cheaper and burns cleaner than these traditional fuels. Additionally, propane generators tend to last longer and require less maintenance than gasoline or diesel generators, which can save you money in the long run.
