Choosing the right used generator set

When it comes to a used generator set, you need equipment that can perform its intended purpose in an effective and efficient manner. This means you get value for your money. While one of the options would be to invest in a new generator set, it may be an expensive undertaking, especially considering that you can get a quality and efficient used generator that is up to the task. However, it is important to take into consideration a variety of factors to ensure the equipment you invest in will be value for your money, and also work out efficiently for what you want it to accomplish.

What to look for in a used generator set?

a) Assess the age of the generator

When investing in a generator set, it is important to consider how long it has been in usage, age, and run time. Most generators have an odometer that keeps track of how many hours the generator has been running. It is also important to inquire about what the generator was used for. For example, you may want to know whether it was used as the main power source, or as a standby. This is because a generator used as a backup or standby power source will be in a much better condition than one used as the main source. However, this information may not always be available, since some generators may be acquired by suppliers through auctions or foreclosures.

b) Assess your power needs

When you decide to invest in used generator sets, you will want one that is capable of fulfilling the task you want it to perform. It is important to take into consideration all the key components you want to be powered by the generator. It is highly advisable to seek the services of a certified electrician to help you in computing the power you will need the generator to have. This is because the generator load requirements will depend on a variety of factors and what it is expected to accomplish.

c) Fuel type

One of the most important factors to consider in a used generator is the type of fuel it will be running on. Most generators will either use natural gas or diesel. Each of these fuel types has its advantages and disadvantages. While diesel generators are mostly preferred as back-up power sources, they are costly and limited by their fuel capacity. The period which a diesel can run will depend on its fuel capacity. This means you will need to put in measures to ensure the tank is being constantly replenished to keep the generator running. This may sometimes be an issue in case of emergency situations such as hurricanes or blizzards. However, diesel generators have lower maintenance requirements than those using natural gas. An advantage of investing in natural gas generators is that they are less costly. They are also free from the limitations posed by diesel-powered engines such as ensuring they are constantly being replenished. This is because they are connected directly to the gas supply pipeline. However, they require regular inspection and maintenance since they use highly combustible fuel. This is to ensure they do not pose any hazardous threats that may occur due to gas leaks. By taking into account the fuel type you want to use for your generator, you can be able to work out on costs so as to choose a type that is convenient for your needs.

d) Visual integrity

It is important to always check for the visual integrity of a used generator to ensure it does not pose a hazard. You should check for wear and tear in all of its mechanical components. If any parts are not at their optimum condition, then it is advisable to replace them. You should also check for cracks, corrosion, and the integrity of the wiring system to ensure everything is fine. There are often times when it is recommended to replace bearings, bushing, bolts, and fasteners of a used generator if a dealer has not done it to ensure the equipment is functioning safely. It is highly advisable to seek the services of a certified electrician to ensure that all components of the generator are in good condition and working fine.

e) Manufacturer

Depending on the brand of the generator, some are known to offer a longer service than others. This is why it is important to also take into consideration the reputation of the manufacturer. This will at least give you an idea of how long and how efficient you can expect the used generator to serve you.


After taking into account the above factors, it is important to purchase your equipment from a reputable dealer. This is because dealing with a reputable dealer means you not only get value for your money but also ensures you have peace of mind by knowing you are investing in a reliable used generator. A reputable supplier will be able to furnish you with as much information about the generator to help you choose one that is ideal for you. It is also important to ensure all essential information such as the condition, age, hours, and usage of the generator is accurate. A reputable supplier will be able to verify this type of information to ensure you are investing in an equipment that will best serve your needs. It is also important to review the warranty information and conditions offered by the supplier. This is will ensure you save on costs should anything happen to the used generator. You may also want to consider other services or logistics that a supplier offers. For example, some suppliers may offer transportation or installation logistics, which will help you in saving costs. When looking for a reputable supplier, you may want to consider looking at online reviews to see what other customers have to say about their experiences with the dealer. This will help you in narrowing down a list of potential suppliers to choose from.
