How Often Should You Run Your Generator? A Guide to Exercise Cycles

Generators are critical to ensuring power availability in situations where there is no mains electricity, such as during a power outage, at remote sites, or for businesses requiring backup power. However, like all machinery, generators require maintenance to perform optimally. One important aspect of generator care is understanding how often you should run your generator. This process is known as "exercising" your generator, and it plays a crucial role in ensuring its reliability when you need it most.

Why You Should Exercise Your Generator

Exercising a generator is the practice of running it periodically to ensure it remains in good working condition. A generator that is left unused for long periods can face various issues. These include fuel degradation, oil settling, and battery drain, which can all lead to problems when you attempt to start it in an emergency. Regularly running your generator, even when you don’t need it for power, ensures it remains ready for use at a moment’s notice.

How Often Should You Run Your Generator?

The frequency of exercising your generator depends on several factors, such as the type of generator, its fuel source, and its intended use. However, the general recommendation is to run a generator at least once every 30 days for about 20-30 minutes. Here’s a closer look at the reasons behind this:

Preventing Fuel Issues

Diesel and petrol degrade over time, and left idle, they can develop moisture and contaminants. Running the generator helps burn through the fuel before it starts to break down and prevents build-up in the engine, which could cause damage. This is especially true for diesel-powered generators, which require particular attention to fuel quality.

If you’re using a generator for backup purposes, you’ll want to ensure that it remains ready to deliver peak performance when required. Running it regularly flushes the fuel lines and prevents the build-up of impurities.

Maintaining the Battery

The battery in a generator is responsible for powering the starting system. A battery that isn’t used for a long time can lose its charge and deteriorate. By exercising your generator, the battery gets the regular charging it needs, ensuring that it’s ready for the next time you need to start the engine.

If your generator has a battery, it’s crucial to monitor its performance and replace it as needed. Many modern generators, including those from GFE Power Products, feature high-quality, long-lasting batteries designed to handle frequent use.

Lubrication and Moving Parts

Generators consist of many moving parts, and the oil lubricates the engine to keep them running smoothly. When a generator sits idle, the oil can settle, and moving parts may become stiff. Running the generator for a short period allows the oil to circulate and ensures that all the parts stay lubricated.

Regular exercise helps avoid the risk of metal parts rubbing together without proper lubrication, which could result in significant engine damage.

Testing for Efficiency

Running your generator occasionally gives you the opportunity to test its performance and identify any potential issues before they become major problems. Whether it's a misfire, strange noises, or a simple issue with the electrical components, exercising the generator helps you stay ahead of any necessary repairs or maintenance.

Best Practices for Exercising Your Generator

To get the most out of exercising your generator, follow these best practices:

1. Check the Manufacturer’s Recommendations: Always refer to your generator's user manual for manufacturer-specific recommendations. While most manufacturers suggest a monthly exercise cycle, some generators might have different requirements, especially when it comes to the duration of the run time.
2. Monitor the Fuel: Ensure that you’re using fresh, clean fuel. If your generator uses gasoline or diesel, consider rotating the fuel supply so that older fuel doesn’t go unused for too long. You should also ensure that the fuel is stored in the proper conditions to prevent contamination.
3. Run the Generator Under Load: While running your generator for 20-30 minutes a month is important, it’s even better to run it under load during exercise cycles. A load test ensures that the generator is performing as it should under normal operational conditions. For example, use it to power your business or home for a short period. This exercise helps ensure that the generator is ready for a larger load when it’s needed.
4. Inspect Regularly: During each exercise cycle, it’s a good idea to conduct a quick inspection. Check for any signs of wear, leaks, or issues with the engine, exhaust, or fuel system. Performing regular checks can help catch potential problems early and prevent costly repairs.
5. Don't Forget the Air Filters: Air filters help ensure that the engine has the clean air it needs to function properly. Over time, these filters can become clogged with dust, dirt, and debris, reducing the generator's efficiency. Make sure to check and replace the air filter as part of your regular exercise routine.
