Generator sets are machines that provide backup power to households and businesses when there is no regular grid supply. They are high-performance, powerful tools with a great diversity of uses. With the right maintenance, a generator can last for many years, which has led to many people considering generator set as a long-term investment. However, one of the most frequently asked questions is, “How long can a generator sit unused?”.
In this article, we will discuss how long a generator can sit unused, the reasons why it can happen, and the consequences that could emerge in such cases. The primary purpose of this article is to educate beginners and those who have little or no knowledge of generator maintenance.
How Long Can A Generator Sit Unused?
In general, a generator needs to run for at least 30-60 minutes every month. This is necessary for all the mechanical parts and components to function optimally, as they require regular exercise. When a generator is left unused for long periods, it can develop several problems that often require extensive maintenance to repair.
Failing to run your generator for several months could cause seals to dry out or become brittle, which can lead to oil and fuel leaks. Additionally, the batteries that power the electric start may also drain, which can result in a complete failure to start to a generator.
It’s important to note that the lifespan of generators largely depends on how well they are maintained. Generally speaking, a generator set that receives proper maintenance will last longer than a poorly maintained one.
Why Generators Can Sit Unused
There are numerous reasons why generators can sit unused for long periods. For example, you may avoid using the generator for an extended time when there is an extended power supply, or if you plan to go on vacation. Additionally, if you live in an area with stable power supply, you may forget to exercise the machine regularly.
In many cases, the lack of use could due to mechanical problems that prevent the generator from operating. In such cases, avoid using the machine and instead, call for professional assistance to avoid causing additional damage.
Consequences of Unused Generators
When a generator remains unused for prolonged periods, several problems may arise. Some of the common problems include:
Fuel and Oil Deterioration
Leaving fuel in the fuel tank for an extended time could cause a few issues such as the development of gum deposits that can clog the fuel system. The oil can also become contaminated with moisture and acids.
Battery Failure
As mentioned earlier, batteries that are left unused can lead to complete discharge and failure to start.
Corrosion
Lastly, when a generator is not in use for a long time, it can begin to corrode from the inside due to moisture.
To avoid the consequences listed above, you should always carry out routine maintenance practices when using a generator.
Conclusion
In summary, how long a generator set can remain unused depends on your level of maintenance. Generally speaking, the generator should be started up for at least 30-60 minutes every month to ensure that all the mechanical components are in good working condition. With proper maintenance, a generator can even last for decades. However, leaving a generator unused for prolonged periods could lead to several problems, such as fuel and oil deterioration, battery failure, and corrosion. Therefore, it is important to follow the proper maintenance schedule when using a generator to ensure that it operates efficiently and lasts for a long time.

FAQs for How Long Can A Generator Sit Unused?
1. How long can I leave my generator unused without running it?
It is recommended to run your generator at least once a month when not in use. If you have to leave it unused for longer than a few months, it is best to store it properly and follow the manufacturer’s recommendations.
2. Can I leave fuel in my generator when not in use for an extended period?
It is not advisable to leave fuel in your generator when it is not in use for an extended period. Stale fuel can cause blockages in the generator’s carburetor, hence it is important to drain the fuel or add a fuel stabilizer to the tank before storing it.
3. Can I store my generator outside during the winter months?
If you have to store your generator outside during winter, it is best to protect it from the elements. You can use a generator cover or build a small shelter to protect your generator from snow, ice or wind. Storing your generator indoors is, however, the best option.
