In the current economic scenario, you may have an option to buy a used, rebuilt, or remanufactured generator. Each type will have its pros and cons and will have an impact on longevity, cost, and reliability. In this blog, let’s discuss how to make an informed decision to choose the right generator between used, rebuilt, and remanufactured.

  • May not have a warranty or have limited repair, which may increase the risk of costly repairs in the future. 
  • Any existing wear and tear will impact the longevity of the generator when compared to the other generators. 
  • Since used generators are old, they may not have modern technological features such as advanced fuel efficiency, remote monitoring, and upgraded emission standards.

Rebuilt generators 

They are disassembled, cleaned, inspected, and replaced with broken parts. The parts that are in working condition are reused. 

Advantages: 

  • Enhanced reliability compared to used generator engines.
  • Rebuilt and maintained engines will last longer, and they are compared to new generator engines.
