Generators are important to any company or family that depends on backup power or portable power. Although new generators come equipped with all the latest advanced technologies, most buyers opt to buy used generators because they can offer similar performance at much lower prices. Not all second-hand generators are cost-effective purchases, though. It all relies on knowing what to search for and what to stay away from.
Initial Costs vs. Long-Term Reliability
One of the main reasons why people go in search of second-hand options is related to cost. The fact of the matter is that a generator can last for thousands of hours without any issues; thus, there could be significant financial benefits in buying the same at a low cost. However, long-term cost benefits are related to something beyond merely obtaining an economic cost advantage.
Thus, it becomes essential to understand the condition of the generator, both physical and operational, in order to make the purchase. In situations where the second-hand generator has been well-maintained, it can serve effectively for many years.

Hours of Use: Unravelling What They Mean
The total number of hours run in the generator gives an instant indication of the lifetime the generator has seen so far. Much like the miles in a vehicle, the number of hours gives an indication of how much the engine has worked. For example, a generator that has unusually high hours can still be in good working condition but might need more frequent servicing or could be due for its big service.
However, the hours alone do not paint the complete picture. It could very well happen that a generator having worked for many hours at constant but moderate loads might be in much better condition than another, having less hours but heavy start-ups or maintenance issues. It is because of these reasons that maintenance hours are considered equally important as the display hours.
Records of Maintenance Done
One of the most important requirements to check when looking at any second-hand generator for sale might well be its maintenance service history. An ongoing record of oil changes, filter changes, coolant checks, and so on will all go towards showing that the generator has had regular maintenance performed.
In cases where there are missing or inconsistent or generalized records, it becomes difficult to assess the treatment accorded to the generator. Buyers need to exercise caution in such situations because missing information can point towards potential concerns.
Physical Regarding and Storage Condition
The appearance of the generator can reveal much about its history. Holes in the finish due to rust, dented surfaces, corroded terminals or wires, or other damage can reveal neglect in terms of storage or handling. Generators that are exposed to the weather when improperly protected in storage can easily display signs of such exposure.
It helps to inspect the engine bay, frame, fuel tank, and electrical connections. After all, when the generator is in good condition and well-presentable, there is a good chance the owner took good care of it.
Load Tests & Performance Tests
One of the most significant aspects when purchasing a second-hand generator is the Load Test. It helps to ensure how well the generator can function under actual working conditions. During the process, the generator must readily start, operate smoothly, and maintain constant voltages without much smoke and noise. Hesitation, surging, or vibration can reveal other issues.
Listening to the engine and keeping an eye on the temperatures and outputs during the test can give good indications of engine condition.
Are Pre-Owned Units Worth It?
In most cases, second-hand generators can make for very good buys, especially where they come from reputable dealers. It may happen that a generator with an exemplary maintenance record, not so many operating hours, and in good physical condition can last many years without proving to be too heavy financially when compared to buying new. One can make sure whether or not a second-hand generator can meet all requirements by checking the parameters above. Also, second-hand generators can turn out to be quite smart purchases when consumers understand how to make selections.
