When power goes out, a generator will keep your home or business running until electricity is restored. But how long can you run a standby generator continuously?
You may be surprised to learn that a generator can run indefinitely as long as fuel is available. However, several factors can also affect the generator’s long-term health.
It’s a good idea to stop the generator once every 100 hours of continuous run time to check the oil level. Just like taking a drive in a car, you’ll want to check the oil to make sure your engine is in top condition.
Want to learn how you can extend the life of your home standby generator? Read on for standby generator maintenance tips you may not know about.
How Long Can a Standby Generator Run?
A home standby generator can run continuously for weeks so long as the tank contains propane or natural gas. That said, the continuous runtime can vary depending on the type of generator you have.
Fuel type, tank capacity, and generator model can affect how long a standby generator can run. Regardless, shutting the generator down once every 100 hours is ideal.
Shutting the generator down once every 100 hours lets you inspect the oil level and the generator’s overall health.
Don’t worry if the oil level is low. Simply add more and resume running the generator.
Can a Standby Generator Run Continuously for Days?
Yes. Many standby generators can run continuously for days. Generators are designed to provide backup electricity in emergencies. They can give your household power even in extended outages.
Note: A generator’s ability to run for days depends on certain operating conditions. In general, a generator can run for days so long as there’s fuel. However, running a generator close to its maximum capacity strains the engine.
In this case, be sure to check that the oil level, coolant, filter, and other components are in top condition. You can also shut the generator down after 12 hours for 30 minutes of cooling and servicing.
How Long Can a Standby Generator Run on Natural Gas?
A standby generator running on natural gas can run continuously for days because its fuel is often supplied through a utility line. The exact runtime still depends on the generator’s size and electrical load, but natural gas generators can run longer than propane ones.
Natural gas generators can potentially power more appliances. You don’t have to continuously refill the tank, and there’s no need to store huge amounts of fuel at home.
The downside of natural gas generators is that they’re dependent on the gas supply. If the gas supply is interrupted, you won’t be able to run the generator.
Installation for natural gas generators is more complex, so it’s best to consult a professional.
How Long Can a Standby Generator Run on Propane?
Propane generators can also run continuously for days. Still, runtime depends on the propane you have available at home.
Unlike natural gas, propane generators have a tank that you have to refill. The generator stops once you run out of fuel.
For propane generators, the total runtime is affected by tank size, temperature, and electrical load. Your installer can tell you the exact runtime based on your circumstances.
If you’re considering buying a propane generator, don’t forget to consider your storage space and the propane’s shelf life.
Does a Standby Generator Need to Be Turned Off?
A standby generator doesn’t necessarily have to be turned off just because it has been running for an extended period. Many generators can operate for a long time during power outages.
To add to this, generators can detect when power has returned. These generators automatically shut down according to their programmed sequence.
Usually, you don’t turn an active generator off unless there’s a specific reason. When you should shut a generator down also depends on the manufacturer’s instructions.
Most manufacturers give guides on how long a generator can run continuously. Yet, if you notice overheating, unusual light flashes, and noises, there may be a problem. In this case, turn the standby generator off for servicing.
Why Is Oil Level Important During Extended Generator Use?
Oil is important when you’re using the generator for extended periods. It lubricates the generator’s moving parts.
Oil reduces friction and prevents the generator from overheating. If the oil level gets too low, there will no longer be lubrication to protect the engine. Eventually, low oil levels lead to serious damage.
Today, many generators automatically detect whether oil level is too low. Nevertheless, you should still check the oil level every 100 hours of usage.
What Can Affect How Long a Generator Runs?
Generators have different run times due to several factors. Here’s what can affect how long a generator runs.
- Fuel Supply: Natural gas generators can run longer than propane generators when there’s a reliable utility supply.
- Electrical Load: Generators with heavier electrical loads naturally use more power. High-demand equipment like refrigerators and air conditioners increase fuel consumption.
- Generator Size: Larger generators can handle bigger loads more efficiently.
- Maintenance: Low oil, clogged filters, and worn components can affect performance and decrease a generator’s run time.
- Environmental Conditions: Generators require cool conditions with proper ventilation. Excessive heat can affect performance.
How to Prepare Your Standby Generator for a Long Power Outage
If you know a power outage is coming, you should prepare your standby generator. Taking a little time to check your generator beforehand can ensure it’s ready when you need it.
- Check the Fuel Supply: For propane generators, make sure you have enough fuel for the outage. For natural gas generators, check that the connection is in good condition.
- Verify the Oil Level: Verify the oil level and schedule an oil change if needed.
- Inspect the Battery: Make sure the battery and other connections are working.
- Clean the Generator: Clear any leaves and debris that could block the airflow.
- Schedule a Service: If you see a potential problem, have a qualified technician inspect the generator.
When Should You Have Your Standby Generator Serviced?
Having your standby generator serviced is a good practice that can extend the generator’s life. But when should you have the generator serviced?
In most cases, manufacturers provide maintenance schedules. Service intervals vary based on the model, brand, and usage.
Following the maintenance schedule keeps the generator in peak condition for operating at any time.
Aside from this, have your generator serviced when you notice signs of wear. If the generator has unusual noises and inconsistencies, it’s time for servicing.
One good tip is to have your generator serviced before seasons with severe weather. A qualified technician can help you prepare your generator for the next emergency.
