Pay Attention To These Aspects When Buying A Second-Hand Generator

Sep. 09, 2021

At present, there are many kinds of second-hand generators of various brands and models on the market. When choosing a second-hand generator, the user does not know the performance of each second-hand generator set. Therefore, the user must pay attention to the following when buying a second-hand generator.


1. Load balancing test.

The mobile load group unit is designed to accurately simulate the operating load when the generator is running. It matches the power output of the generator, and ensures that the generator will not be overloaded, resulting in failure to supply power to the building.


2. Generator supplier.

Where and from whom you buy a second-hand generator is crucial because it will give you an idea of the condition of the equipment. Industrial diesel generators are complex mechanical equipment and need to be maintained and tested by senior engineers in order to operate at the best efficiency.


We strongly recommend that you choose a supplier that has a thorough knowledge of generators and a good record of selling second-hand generators. Because they will thoroughly inspect the generator before selling it, it is very safe for you. Generators may prove to be expensive, so it is important to ensure that you buy from professionals or organizational units you can trust.


3. Generator age, hours and usage.

The first thing before buying a second-hand generator should be to check the operating hours, age and usage of the generator set you are interested in buying. Just like a car, most generator engines have an odometer reading that tells you how many hours it has. It is also helpful to understand its purpose and whether it is used as a backup power source or a main power source.


Generators used for backup power are generally better maintained and in better condition than generators used for main power. However, keep in mind that some dealers usually obtain generators through foreclosure, so they usually don't know its history or where it came from.

4. Reputation of generator manufacturer.

When buying a used generator, it is recommended that you pay attention to the history and reputation of the generator manufacturer. It goes without saying that any manufacturer with bad reviews or reputation should be avoided as much as possible. Once you know that you have chosen a trustworthy manufacturer with a good reputation for producing reliable equipment, invest and buy with confidence.



5. Visual inspection.

If you don't understand, you can ask a professional technician to check whether all mechanical parts on the generator are worn or fatigued, including whether any parts have cracks or corrosion accumulation. Any parts found to be defective should be replaced. For example, bearings and bushings are difficult to test for wear. Jiangsu Starlight Electricity Equipments Co.,Ltd. recommends replacing them regardless of their function or condition.


Although second-hand generators usually do not have a warranty period, the price of second-hand generators usually has a great advantage, which is much lower than the retail price of new units, which can save more than 50% of the cost or even more.
