How much propane to run a generator?

FAQs → How much propane to run a generator?

When running a generator on propane, the amount of fuel required depends on several factors, including the generator's size, the load it's powering, and its efficiency. Here are some general guidelines to help estimate your propane usage:

1. Generator Size: Larger generators consume more propane. Typical sizes range from 2000 to 12,000 watts.

2. Load: The load refers to what you're powering. For example, powering lights and small appliances uses less energy compared to running refrigerators or air conditioners. A rough estimate:

• 2000-watt generator: 1-2 pounds of propane per hour

• 4000-watt generator: 2-4 pounds per hour

• 6000-watt generator: 3-6 pounds per hour

• 12,000-watt generator: 5-10 pounds per hour

3. Efficiency: The efficiency of your generator's propane conversion affects fuel consumption. High-efficiency generators use less propane.

Here’s an example calculation:

If you have a 4000-watt generator running for 8 hours with a moderate load (2-4 pounds per hour) and 90% efficiency, you’d need approximately 16-32 pounds of propane for 8 hours of operation.

These are rough estimates, so refer to your generator's manual for more precise fuel consumption rates based on your specific model and usage conditions.
