How To Calculate: How Much Propane Does A Generator Use?
Imagine having a propane generator to power your wood lodge in the forest. You lose electricity after a winter storm and must use your generator to keep your cabin warm and cozy during that time.
You must first know how much power your cabin uses in order to calculate how much propane you need. Assume your overall load is 3000 watts per hour. You also know that you want to run your generator for a total of 36 hours over the course of three days, or 12 hours per day.
To calculate the total propane needed, follow these steps:
Step 1: Convert watts per hour to horsepower
1 horsepower = 500 watts/hour
So, 3000 watts per hour is equal to 3000/500 = 6 horsepower
Step 2: Convert watts per hour to BTUs
1 horsepower = 10,000 BTUs
Therefore, 3000 watts per hour is equal to 3000/500 x 10,000 = 60,000 BTUs.
Step 3: Convert watts per hour to gallons of propane
1 gallon of propane = 91,500 BTUs
1 BTU = 1/91,500 gallons of propane
So, 60,000 BTUs is equal to 60,000 x 1/91,500 = 0.655 gallons of propane
Step 4: Multiply by the number of hours you need to run the generator
You want to run your generator for 36 hours, so multiply 0.655 gallons by 36 to get the total amount of propane needed: 0.655 x 36 = 23.58 gallons
If you have a 100-gallon propane tank, it will last for 100/23.58 = 4.3 days, or about enough for your needs.
Alternatively, if you store propane in portable cylinders that are measured in pounds, you can use the formula:
Number of pounds to run a generator for 1 hour = number of watts x 4.24 ÷ 4575
So, to run your generator for 1 hour at 3000 watts per hour, you will need 3000 x 4.24 ÷ 4575 = 3.86 pounds of propane.
For 36 hours, you will need 3.86 x 36 = 138.96 pounds of propane, or about 69.5, 20-pound propane cylinders.
By using these formulas and converting between different units of measurement, you can accurately determine how much propane you need to power your generator for a specific amount of time.
