The worldwide electricity consumption is high, it is a vital need to support economical growth. On the other hand the main grid supply is not always available to provide the basic or additional requirements for electrical power, for short or longer term.

The Doosan Portable Power G400 generator has been designed to be your  reliable electrical power supply for jobsite needs, whatever the application is. From large road works with concrete or asphalt batch plants or construction sites with concrete pumps, quarries, shipyards, major concerts or events, to the most demanding industrial application or power plant, the G400 will power your productivity!

400V / 50Hz


The Doosan Portable Power G400 generator is built around a reliable powertrain, featuring a Cummins Stage II engine coupled to a Leroy Somer alternator with standard heavy duty winding impregnation. The AREP alternator excitation system is a standard feature, providing additional electric motor starting capability, compared to shunt alternators.
The powertrain sizing is critical to ensure stable and reliable generator electrical output and provide a strong load take-over performance.

A sound attenuating enclosure, built on the frame, allows the complete generator package meeting or exceeding applicable noise regulations. The enclosure panels are powder coated, ensuring a good preservation of your invested capital.
Handling operations have been made easy by the standard combination of central lifting eye and forklift pockets integrated in the frame.

The standard G400 configuration features a 2.170l fuel tank to reach 33 hours runtime @ 75% of the load. The accessibility to the generator maintenance points has been optimized to reduce field intervention times.

An optional switchable dual frequency 50/60Hz feature, combined with a digital control panel, provides the G400 with the best versatility and application conditions monitoring system.
The availability of synchronization option for this platform will provide maximum flexibility and adaptability for rental companies. This allows to use two or more generators, of same or different electrical output, in parallel with the best flexibility to optimize the match between electricity production and demand from the load.
Grouping operator's interface, control panel and electrical protection devices in the same area, drastically improves the safety of use of our generators.
