Quick Answer
A dual-fuel generator is insufficient when a larger power demand cannot be met by the combination of gasoline and propane. This limitation occurs when high-wattage appliances or tools are used simultaneously. The available fuel supply becomes depleted too quickly.
Insufficient Power Capacity
A dual-fuel generator, such as a 5000-watt unit, might have a maximum power output of 4500 watts from propane and 4500 watts from gasoline. However, if you’re running a 2000-watt air conditioner, a 2000-watt refrigerator, and a 1000-watt microwave simultaneously, the total power demand would be 5000 watts. In this scenario, the generator would be unable to provide enough power, even with both fuels engaged.
Fuel Consumption Rates
Let’s take a closer look at fuel consumption rates. A 5000-watt dual-fuel generator might consume 2 gallons of gasoline per hour when running at maximum capacity. Propane consumption would be approximately 1.5 pounds per hour. If you need to run your appliances for an extended period, you might quickly deplete your available fuel supply, leaving you without power.
Tri-Fuel Generator Options
Consider upgrading to a tri-fuel generator that can run on gasoline, propane, and natural gas. These generators offer more flexibility and can provide a higher power output. For example, a 7000-watt tri-fuel generator might have a maximum power output of 6000 watts from gasoline, 6000 watts from propane, and 7000 watts from natural gas. This increased power capacity can help ensure that you have enough energy to meet your needs.
