How Long Can I Leave My Generator Running? 

If you have a standby generator on your property, you may have numerous questions about how long you can keep your generator running each time you use it. While standby generators can run for quite a while, especially compared to portable generators, there are some limits on how much time can pass before you should shut your generator off. Here’s everything that you need to know about how long you can leave your generator running, as well as who you should call for all of your generator services—

Run Times for Different Generator Types

Different generator types have different run times. You should familiarize yourself with the type of generator that you have and not exceed the run time for the specific type, make, and model. 

• Gas-powered portable generator. A gas-powered portable generator has the shortest run time, but can still be useful in a pinch. Generally, gas-powered portable generators can run for up to 12 hours (sometimes less, depending on size) without needing to be cooled and refueled. 
• Propane-powered portable generator. If continually refueled, a propane-powered portable generator has a significantly longer run time compared to a gas-powered portable generator—up to eight days. However, while this is a long run time, note that these generators are best for powering smaller appliances, equipment, and mobile homes, not full-size residential homes and businesses. 
• Standby natural gas generator. A standby natural gas generator has the longest run time by far. Unlike gas- and propane-powered portable generators, a standby natural gas generator can run continuously for up to three weeks in most cases. Of course, this is for a generator that is working well and has been well-maintained.
