Generators represent a significant investment, so understanding their lifespan is essential for homeowners and businesses that depend on backup power. This knowledge aids in budgeting, maintenance planning, and overall preparedness. Today, let’s delve deeper into the factors that influence the lifespan of these powerful machines and explore tips to ensure they stand the test of time.

What is the Average Lifespan of a Diesel Generator?

On average, a well-maintained diesel generator can last from 20,000 to 30,000 hours, or even more. Generally, this equates to about 20-30 years of use. But please note that this is only an approximate estimate. For example, a standby diesel generator used only for emergencies is going to hit the 10,000-hour mark much later than one that is used constantly. On the other hand, proactive measures can greatly prolong the generator’s operational life.

Two Key Factors Affecting Your Diesel Generator Lifespan

Multiple different factors influence the life span of diesel generators including the brand, age, sizing, environment and so on.  Above all, here are the two most significant points:

1. Use and Quality

The usage frequency and quality of a diesel generator play an important role in determining its lifespan. The number of hours your generator operates is a primary factor impacting its longevity. Ideally, generators should be running at their optimal loads of 75-100%. If it is often overworked, there will be surely more wear and tear on the equipment, which can shorten the lifespan of the generator. On the other hand, an underused generator that never works at full capacity usually gets clogged up with a build-up of carbon deposits. This phenomenon is called “wet stacking”. Thus, properly sizing the generator according to usage frequency to match the anticipated workload can help maximize its lifespan.

Additionally, we can understand the quality of the generator is the fundamental factor affecting its lifespan. Opting for a reputable manufacturer and ensuring high-quality materials and advanced engineering techniques tend to have a longer life expectancy.

2. Maintenance Practices

How long you can run a generator ultimately depends on how well you care for it over the years. Maintenance is essential to maximize the performance of your diesel generator and prolong its lifespan. Learning how to care for your generator will also prevent potential problems, such as expensive repairs, lack of power and hazardous conditions.

Following the maintenance schedule and using the machine properly will bring longer life, better performance and safer operation. Perform each maintenance procedure at the time period indicated or after the number of operating hours indicated, whichever comes first.

 

Routine Maintenance

 

Monthly inspections — which should also include exercising the transfer switch and running the generator under load for a minimum of 30 minutes. This help keep the engine and its components lubricated and ensure reliable performance when needed, as well as help detect most problems.

Notice:

• Always perform above maintenance schedule after the number of operating hours or year(s) indicated, whichever comes first.
• Clean the primary filter when the maintenance indicator of the air filter displays red sig Change the primary and safety filter(no matter how long it has run) if it has been cleaned for five times.
• Above maintenance intervals should be shortened if the machine is often used in extreme environment.

Yearly Professional Maintenance is Also Very Necessary

Besides general maintenance, schedule professional service for your generator at least once a year. These annual inspections can identify potential issues that might be missed during routine maintenance. This kind of maintenance should be performed by certified engineers to thoroughly check all aspects of the generator. It’s best to fix these problems before they’re noticeable. On the other hand, by adhering to these best practices, which help ensure your standby generators operate efficiently and tend to have a longer service life.

As mentioned above, consistent and thorough maintenance is paramount. Following the manufacturer’s guidelines ensures that your generator remains in optimal conditions.

Conclusion

Diesel generators are a vital source of backup power for businesses and industries. By understanding the factors that affect their lifespan and implementing proper maintenance and operation practices, you can gain more success in extending the life time of your diesel generator as long as possible while improving efficiency.
