It doesn’t matter if you are purchasing a used diesel generator for your business or your home, there are a few factors to consider. While it is possible to get a high-quality unit at a reasonable price, it doesn’t happen without time or effort.
One of the first things you must consider is the type of generator that will best fit your needs. There are several options, including electric, propane, diesel, and natural gas.
Some tips that will help you make the right decision can be found below.
Choose the Right Fuel Type
The fuel will determine what your generator runs on. This is considered the single-most-important factor to consider before you choose a generator. The most common types of generators available include natural gas and diesel generators.
Diesel generators are commonly preferred for backup and emergency power solutions. However, there is a downside to these units. This includes the costs of the units and the limited capacity of the fuel tank.
The max duration of diesel generators will run over the time period that is based on the fuel tank’s fuel capacity. If you choose a diesel generator, you need to pre-plan for these contingency measures. If the power happens to go out, do you have someone appointed to make sure the diesel fuel is replenished constantly?
Sometimes, this will pose an issue, especially during emergencies like inclement weather or hurricanes.
One of the most significant benefits of a diesel generator is the reduced maintenance requirements compared to the natural gas counterparts.
Natural Gas Generator
Usually, natural gas generators will have a much lower purchase price. However, they also come with more maintenance needs because these generators use a highly combustible fuel source.
Regular service and inspection can be conducted to make sure there aren’t any hazardous gas leaks present. Also, if you live in a location that is susceptible to natural disasters, utility companies are likely going to turn off the gas lines during these times to prevent the possibility of an explosion.
A benefit of a natural gas generator is that there are no limitations or restrictions to the fuel supply in the way of a fuel tank. That is because the generators are connected right to the natural gas pipeline in the area.
The Age of the Generator
If you are like most people, you would never purchase a used vehicle without knowing the lifespan and mileage of the vehicle. This same rule applies to diesel generators.
Make sure you get an estimate of how long the generator has been used. Most of the units are designed with a built-in odometer. This will give you some insight into the history.
If it was used on an ongoing basis to provide power, you could see that it has more wear on it than one that was used for supplemental standby power. As a general rule, standby generators used for backup power are usually better maintained than those that are used continually.
Check the Manufacturer and Model of the Generator
Purchasing a used generator is like buying a car. Be sure you do plenty of research on the manufacturer and the model to make an informed decision. You would never purchase a used vehicle in a brand that you were not familiar with or that you trusted, right?
When it comes to buying a 500 kw diesel generator, or any make or model for that matter, you have to know what you are purchasing. Make sure you purchase a unit that is high-quality materials, and that has a history of running for an extended period of time.
Conduct An Inspection
Be sure you gather as much information as possible about the maintenance of the machine through the records and by asking the previous owners to give you a history of repairs and use. You should never purchase a used generator online. Doing this means that you won’t be able to tell if there are any visible wear and tear.
When handling the inspection, look for any components that appear worn out, check the welding and wiring to see if everything is in proper working condition, and look at all the components to ensure there are no issues.
The Initial Load Test
Use the calibrated load bank to test the capability of the generator’s engine effectively. Watching the complete unit function and operating while under duress is the best way to find any damages or malfunctioning engine components. The load test is similar to taking a used car for a test ride and driving it for about an hour.
Find a Reputable Dealer
If you don’t know what you are getting into, you should avoid purchasing a standby generator from anyone other than a reputable broker or dealer. Most used generators require maintenance and testing handled by a certified electrician.
You cannot rely on that type of maintenance from must anyone. Instead, search for a dealer with a history and a solid reputation of service.
Purchasing the Right Used Diesel Generator
When it comes to buying the right used diesel generator, there are several factors to consider. Each of the points above gives you good advice and information about what you should look for when buying a generator.
With used generators, there is no question that finding the right one matters. However, this is true for any used equipment. If you are looking for more helpful information, be sure to check out some of our other blogs.
