Here’s a simplified table to guide you:
| Generator Size (kW) | Average Propane Consumption at Half Load (Gallons per Hour) |
|---|---|
| 5-7 | 0.5 – 1 |
| 7-12 | 1 – 2 |
| 12-20 | 2 – 3 |
| 20+ | 3 – 5+ |
2.2. Example Calculation
Let’s say you have a 10 kW generator with a propane consumption rate of 1.5 gallons per hour at half load. You estimate you’ll be using about 60% of the generator’s capacity and need to run it for 24 hours.
- Fuel Consumption Rate at Half Load: 1.5 gallons per hour
- Load Percentage: 60% (Slightly above half load, so increase the consumption rate slightly)
- Adjusted Fuel Consumption Rate: Approximately 1.7 gallons per hour
- Runtime: 24 hours
- Total Propane Usage: 1.7 gallons/hour x 24 hours = 40.8 gallons
Therefore, you’ll need approximately 40.8 gallons of propane for 24 hours of runtime. To get precise guidance, consider consulting with the Ph.D. experts at HOW.EDU.VN. They can help you refine your calculations based on your specific equipment and needs.
3. Choosing the Right Propane Tank Size

- Generator’s Propane Consumption Rate: How many gallons per hour does your generator use?
- Desired Runtime: How many hours do you want your generator to run without refueling?
- Safety Margin: It’s wise to have a safety margin to account for unexpected extended outages.
The formula for calculating the required tank size is:
Tank Size (Gallons) = (Propane Consumption Rate (Gallons/Hour) x Desired Runtime (Hours)) + Safety Margin
For example, if your generator consumes 2 gallons per hour, you want it to run for 48 hours, and you want a 20% safety margin:
Tank Size = (2 gallons/hour x 48 hours) + (0.20 x (2 gallons/hour x 48 hours))
Tank Size = 96 gallons + 19.2 gallons
Tank Size = 115.2 gallons
In this case, you would need a propane tank that can hold at least 115.2 gallons to meet your needs. Propane tanks are commonly available in sizes like 120, 250, 500, and 1,000 gallons.
