Doosan Portable Power’s G145 Tier-3 generator is known for its reliability, user-friendly controls and ability to provide lots of power in critical applications. The G145’s hardened enclosure protects a Leroy-Somer alternator that provides the G145 with best-in-class motor starting performance. With nearly 20-hours of onboard fuel, a John Deere Tier-3 engine and rugged running gear, Doosan Portable Power’s G145 will reliably power projects in the harshest environments.

The G145 Tier-3 from Doosan Portable Power is a hardened packaged that has proven its worth on many jobsites. Inside the hardened, sound attenuated enclosure is a Leroy-Somer alternator that uses AREP – an extra set of windings that provides the G145 with better starting performance than competitors with shunt alternators. A John Deere engine and nearly 24-hours of onboard fuel maximizes the G145’s uptime at any jobsite.  Enhancing performance in even the most extreme temperatures is an optional Tundra Package, which ensures startup and reliable operation in temperatures as low as -40˚F/˚C. The package includes a coolant heater, oil pan heater, battery charger, battery heater pad and heated breather hose.

  • The Voltage Selector Switch (VSS), is a standard feature on Doosan Portable Power generators under 325 kVA (260 kW). The VSS allows operators to meet the application's power requirements by selecting 480V-3Ø, 208/240V-3Ø or 240/120V-1Ø with the flip of a switch. The VSS is also protected - if the VSS door is opened during operation, then the generator will shut off to prevent any damage to the generator if someone intends to change voltage selection while the machine is running.
  • With rugged running gear, as well as a variety of environment solutions and electrical connection options, Doosan Portable Power's G145 Tier-3 can go anywhere to power your success at any jobsite.
  • Users can be easily trained to operate a G145 Tier-3 because it features Doosan Portable Power's simple and well-lit control panel. Clearly labeled controls, visible gauges and a full diagnostic display allows operators to quickly assess problems and find an accurate solution.
