Quick Answer
If a generator runs out of fuel during use, it will typically shut down, and the user will be left with a non-functional machine until more fuel is added.
Sudden Shutdown Risks
When a generator runs out of fuel, it can suffer from a sudden shutdown, which can cause damage to the engine and other components. This is because the engine may not have time to cool down properly, leading to overheating and potential engine damage. In some cases, the sudden loss of power can also cause damage to the electrical system, including the alternator and other components.
Importance of Fuel Gauges
To avoid this situation, it’s essential to use a generator with a reliable fuel gauge. A fuel gauge can help the user keep track of the remaining fuel level, ensuring that they don’t run out of fuel when the generator is in use. Some generators come with a simple mechanical gauge, while others have a digital display that shows the exact fuel level. When choosing a generator, look for one with a fuel gauge that’s easy to read and accurate.
Portable Generator Sizing Considerations
When selecting a portable generator for off-grid use, consider the power requirements of the devices you need to run. A general rule of thumb is to size the generator to deliver 1.5 to 2 times the total wattage of the devices. For example, if you need to run a 300-watt refrigerator and a 150-watt light bulb, choose a generator with a minimum capacity of 900 to 1200 watts. This will help prevent the generator from running out of power when it’s most needed.
