Quick Answer
A 20-gallon propane tank is suitable for a dual-fuel generator with a maximum output of 10,000 watts, while a 30-gallon tank is recommended for generators with a maximum output of 15,000 watts.
Choosing the Right Propane Tank Size
When selecting a propane tank for your dual-fuel generator, it’s essential to consider the generator’s maximum output and the tank’s capacity. A general rule of thumb is to choose a tank that can hold at least 1-2 pounds of propane per hour of generator operation. For example, a 10,000-watt generator that runs for 10 hours will consume approximately 20 pounds of propane.
Calculating Propane Consumption
To determine the required propane tank size, you can calculate the generator’s propane consumption based on its fuel efficiency. Most dual-fuel generators have a fuel efficiency rating, typically measured in gallons per hour or pounds per hour. For instance, a 10,000-watt generator with an efficiency rating of 0.75 pounds per hour would require a 20-gallon tank to operate for 10 hours.
Tank Size Guidelines
Based on the generator’s maximum output and fuel efficiency, here are some general guidelines for propane tank sizes:
- 20-gallon tank: suitable for 10,000-watt generators
- 30-gallon tank: recommended for 15,000-watt generators
- 40-gallon tank: suitable for 20,000-watt generators or larger Keep in mind that these are general guidelines, and the actual propane tank size required may vary depending on the generator’s specific fuel efficiency and operating conditions.
