Description :

Available now in Bourbon, Indiana, this Cummins Onan 50 kW generator for sale is an enclosed diesel-powered commercial generator showing 2,857 hours and now priced at $8,999, reduced from $9,500. Mounted over its fuel tank and housed inside a sound-suppressed enclosure, this unit offers a practical power solution for farms, shops, commercial properties, contractors, agricultural facilities, and other operations needing substantial standby or supplemental electrical power.

Powered by a Cummins 4B3.9-G2 diesel engine, this generator combines proven industrial diesel power with a useful 50 kW output range. The seller reports that the unit can be configured for 1-phase or 3-phase power, broadening its usefulness for buyers with different electrical requirements.

For someone searching for a used commercial generator without the expense of purchasing a comparable new unit, this Cummins Onan deserves consideration.

Cummins-Powered 50 kW Generator

At the heart of this generator is a Cummins 4B3.9-G2 diesel engine. Based on the supplied engine information, the engine is rated at approximately 82 horsepower / 61 kW at 1,800 RPM.

The Cummins-powered configuration makes this generator particularly relevant to agricultural, commercial, industrial, and contractor applications where diesel-powered electrical generation is preferred.

Its 50 kW output rating places it well above smaller portable generators while remaining a manageable size for operations that do not require a much larger industrial generating system.

Potential buyers may consider this generator for applications such as:

  • Farm buildings
  • Agricultural operations
  • Equipment shops
  • Commercial facilities
  • Warehouses
  • Maintenance buildings
  • Construction sites
  • Remote work locations
  • Pumps and motors
  • Emergency backup systems
  • Supplemental electrical power

Actual suitability depends on the electrical load and configuration required. Buyers should have a qualified electrician or generator professional confirm compatibility with their intended application.

Enclosed and Sound-Suppressed Design

Unlike an open-frame generator, this Cummins Onan is housed inside an enclosed, sound-suppressed cabinet.

The enclosure provides an additional layer of protection around the generator components and can help reduce operating noise. This can be especially useful around farms, commercial buildings, shops, equipment yards, livestock facilities, and other locations where an open generator may be less desirable.

Its cabinet-style construction also gives the unit a cleaner, more self-contained appearance for permanent or semi-permanent installations.

Fuel-Tank-Mounted Configuration

Another useful feature is the generator's fuel-tank-mounted design.

Rather than relying on a completely separate external fuel tank arrangement, the generator is positioned directly over its fuel tank, producing a compact and self-contained package.

This configuration may simplify installation planning and placement for buyers looking to establish backup or supplemental power at a farm, shop, commercial property, or remote site.

Fuel-tank capacity was not supplied and should be verified before purchase.

1-Phase or 3-Phase Capability

One of the most significant features reported for this generator is its ability to accommodate 1-phase or 3-phase electrical power.

That flexibility can substantially increase the number of applications for which the unit may be considered.

Single-phase electrical service may be appropriate for certain farm buildings, shops, residences, and light-commercial facilities. Three-phase electrical service is commonly encountered with larger motors, pumps, shop machinery, industrial equipment, and commercial electrical systems.

Because electrical requirements vary considerably, prospective buyers should independently verify:

  • Available voltage
  • Current phase configuration
  • Conversion or reconnection requirements
  • Amperage
  • Electrical connections
  • Breaker configuration
  • Frequency
  • Compatibility with transfer equipment
  • Compatibility with the intended electrical load

A qualified electrician or generator technician should determine whether the generator meets the requirements of a specific installation.

2,857 Reported Hours

The hour meter shows 2,857 hours.

Operating hours are an important consideration when comparing used commercial generators because they provide buyers with another way to evaluate one unit against another.

No detailed maintenance history or recent major repair information was supplied with this listing. Buyers are encouraged to inspect the generator, review its present operating condition, and request any additional maintenance information that may be available before purchase.

Practical Agricultural and Commercial Applications

A 50 kW diesel generator can fill an important gap between smaller portable equipment and much larger industrial standby systems.

For agricultural buyers, possible applications may include backup electrical power for farm buildings, shops, ventilation systems, pumps, lighting, and other farm infrastructure, provided the electrical requirements fall within the generator's capacity.

Commercial buyers may consider it for:

  • Shops
  • Warehouses
  • Maintenance facilities
  • Equipment yards
  • Small commercial buildings
  • Construction operations
  • Remote properties
  • Backup electrical systems

Its enclosed configuration and integrated fuel-tank setup add to its practicality for buyers seeking a more complete generator package.

Used Cummins Onan Generator Value

This used Cummins Onan diesel generator is now being offered at $8,999, representing a reduction from the previous $9,500 asking price.

That is a $501 price reduction and gives buyers an opportunity to consider a substantial commercial generator at a lower acquisition cost.

The combination of a Cummins diesel engine, 50 kW output, enclosed construction, fuel-tank mounting, and seller-reported single- or three-phase capability makes this unit worth considering for buyers comparing used standby and commercial generators.
