Top Tips for Buying Used Industrial Generators

February 05, 2025
Used Industrial Generators


Buying a used generator can be smart, especially if you want to save money. However, just like buying any used equipment, there are risks involved. To make sure you get a reliable generator that meets your needs, it's essential to do your homework. This guide will cover the tips for buying used generators for your home, business, or any other purpose.

Why Consider Used Generators?
Used generators are a cost-effective solution for many buyers. They are typically cheaper than new ones, making them an attractive option for those on a tight budget. Here are a few reasons why purchasing a used generator could be a wise choice:

  • Cost Savings: Used generators can be significantly less expensive than new models, allowing you to allocate your budget to other vital areas.
  • Depreciation: Like cars, generators depreciate quickly. Buying used avoids the initial depreciation hit.
  • Availability: Sometimes, used generators are more readily available than new ones, especially if you need a generator fast.

Types of Used Generators
Before diving into the buying process, you must understand the different types of generators you might encounter.

  • Diesel Generators: Diesel generators are known for their durability and efficiency. They are ideal for heavy-duty applications and are often used in industrial and commercial settings. If you're considering a used diesel generator for your home or business, check the engine's condition and maintenance history.
  • Electric Generators: Electric generators can run on various fuels, including natural gas, propane, and gasoline. When looking for a used electric generator for sale, consider the fuel type that best suits your needs and the generator's power output.
  • Three-Phase Generators: Three-phase generators are commonly used in commercial and industrial applications due to their efficiency in handling large loads. If you're considering a used three-phase generator for sale, ensure it's compatible with your electrical system.
  • Portable Generators: Portable generators are versatile and can be used for various applications, from powering tools on a job site to providing backup power during a blackout. When looking for used portable diesel generators for sale, check the unit's portability features, such as wheels and handles.

Key Considerations When Buying Used Generators
When purchasing a used generator, it's crucial to perform due diligence. Here are some key factors to consider:

  • Condition and Maintenance History
  • A generator's condition is paramount. Inspect the unit for visible damage, rust, or worn-out parts. Ask for the generator's maintenance history to ensure it has been well taken care of. Regular maintenance is a good indicator of a generator's reliability.
  • Hours of Operation: Like a car's mileage, a generator's hours of operation can give you an idea of its usage and lifespan. Fewer hours typically indicate less wear and tear. However, ensure the hours are consistent with the generator's age and condition.
  • Load Capacity: Ensure the generator you choose can handle the electrical load you require. Calculate your power needs and verify that the generator's output meets or exceeds these requirements. This is particularly important for whole-house or commercial applications.
  • Warranty and After-Sales Support: Even when buying used, some generators may come with a limited warranty or the option to purchase one. Consider this when evaluating your options; it can provide peace of mind and protect you from unforeseen issues.

Where To Buy Industrial Generators
You can look for used generators in several places, each with pros and cons.

  • Online Marketplaces: Websites like Machinio and Surplus Record often list used generators. These platforms allow you to see much of what is available in the market. However, be cautious of scams and inspect the generator before purchasing.
  • Local Dealerships: Local equipment dealers may offer used generators for sale. Purchasing from a dealer can provide added security, as they often inspect and service units before selling them. Aaron Equipment has decades of experience in buying and selling used generators, which can be found on our generator web page.
  • Auctions: Auctions, both online and in-person, can be a great place to find cheap used generators for sale. However, they require careful research and quick decision-making, as sales are typically final. Keep in mind that you will unlikely be able to do load testing before an auction.

Tips for Negotiating the Best Deal on an Industrial Generator
When buying a used generator, negotiating can save you even more money. Here are some tips to help you get the best deal:

  • Research Market Prices: Know the average prices for similar generators to ensure you get a fair deal. Aaron’s Blue Book, containing thousands of prices for used equipment transactions, may be helpful to you in your research. Don't hesitate to contact Erik Eichert at eeichert@aaronequipment.com for more pricing information.
  • Point Out Flaws: If you notice any issues during your inspection, use them as leverage to negotiate a lower price.
  • Be Ready to Walk Away: If the seller refuses to meet your terms, don't hesitate. There are plenty of other options available.

Final Thoughts
Buying a used generator can be a great way to save money while still getting a reliable power source. You can make a well-informed purchase by understanding the different types of generators, knowing what to look for, and where to find the best deals. Inspect the generator thoroughly, check its maintenance history, and ensure it meets your power needs. With these tips in mind, you'll be well on your way to finding the perfect used generator.
