How to buy a used generator?

When looking to buy used a generator for your business operations, facilities, or industrial applications, there is a lot to process. You need to research everything, carefully plan and coordinate your actions to purchase the best available unit.

Remember that buying used diesel generators for sale isn’t simply about picking a machine out of a lineup and calling it a day. This action requires a lot of research on fuel types, brands, service and maintenance, operational power needs, modifications, and attachments.

That’s why we have come up with a general guideline which can help you make the best decision.

Calculate power needs and requirements

One of the first steps when purchasing a used generator is to evaluate your power needs and requirements. This process is also called sizing a generator. Therefore, when sizing a commercial generator, you should consider all necessary equipment that needs to be powered by the commercial generator.

Besides emergency lights and other key utility services that provide a safe working environment for your employees, what other equipment will need to continue running? If you don’t know the answer to this question, consult your master electrician to determine your power requirements and needs.

Choose the fuel type

The type of fuel will determine the type of generator you will get, which is one of the most significant factors before choosing a particular unit. Basically, there are two main commercial generators used in the market, gas, and diesel, each having its pros and cons.

In most cases, diesel generators are used for emergency backup power solutions; however, their downside is limited tank capacity and acquisition costs. If you decide to buy this type, you need to have your staff appointed to ensure diesel fuel is continuously replenished in case of a power outage.

On the other hand, diesel generators are quite easy to maintain compared to natural gas units. Diesel generators also come in portable units, considering onboard diesel tanks can be mounted on the generator.

When it comes to gas generators, they are usually cheaper but have higher maintenance needs. For instance, regular inspections are required due to hazardous gas leaks. If you live in an area prone to natural disasters like tornadoes, hurricanes, wildfires, and earthquakes, the utility company will most likely shut off gas lines to prevent an explosion.

But, concerning the benefits, we don’t have restrictions to fuel supply in the way of the fuel tank because it’s directly connected to a gas pipeline.

Find a trustworthy dealer

Another important thing when buying a used generator is to find a reputable dealer. He or she will provide you as much information as possible about the unit and will be able to answer any questions you may have.

But, pay attention because there are a lot of fake sellers online who try to scam customers. Suppose you are dealing with a reputable seller. In that case, he will verify crucial information about the machine you are interested in buying, like condition, working hours, offer photos, and specify what the generator was primarily used for.
