Generator Runtime On Propane: Duration Facts
how long will a generator run on propane
Generators running on propane offer reliable power, with runtime depending on several factors.
Key Determinants of Runtime
The primary factors are the generator's power output and the propane tank capacity. A higher wattage generator consumes more fuel.
- Propane tank size: common sizes are 20 lb or 100 lb tanks
- Generator efficiency: newer models are more fuel-efficient
- Electrical load: running at half-load doubles runtime compared to full-load
On average, a 20 lb propane tank can run a 5000W generator for about 10 hours at 50% load.
Maximizing Runtime
To extend runtime, use a larger tank or reduce the load on the generator. Regular maintenance also helps improve efficiency.
Propane generators are favored for their clean emissions and stable fuel supply during outages.
Always refer to the user manual for specific runtime calculations based on your model.
