The Doosan G570 is the flagship of the G-Series lineup, delivering 456 kW of prime power (570 kVA, 500 kW standby) from a Cummins X15 engine producing 680 HP. It is the largest mobile generator Doosan offers, positioned for major construction projects, data center temporary power, and large commercial emergency standby.
A Bobcat PG570 rolling off the Statesville, North Carolina production line uses the same Cummins X15 engine, alternator, control panel, and sound-attenuated enclosure as a Doosan G570 — the only difference is the badge on the door. The Cummins X15 platform ensures wide parts availability and factory service support across North America.
The Cummins X15 is a 14.9-liter inline-6 producing 680 HP — the same engine platform used in Class 8 heavy trucks, which means one of the deepest parts and service networks of any diesel engine in North America. At 500 kW standby, the G570 pushes the limits of what a mobile generator can deliver in a single trailer-mountable package.
The X15 achieves Tier 4 Final compliance with a full aftertreatment system (DOC, DPF, SCR). At this power level, maintaining adequate load is important for proper DPF regeneration — operators should avoid sustained operation below 30% load to prevent incomplete regeneration cycles. The 656-gallon integral fuel tank provides enough capacity for extended operations, and the sound-attenuated enclosure keeps noise levels at 76 dBA despite the large displacement.
OnPoint services Cummins X15-powered generators for large commercial and industrial applications in Northern California. The X15 benefits from the deepest Cummins dealer network of any engine in the lineup — it is the same platform used in long-haul trucking, meaning parts availability is unmatched. For operators deploying the G570 on major construction projects or data center temporary power, the main service consideration is aftertreatment health: maintain load above 30%, monitor DPF differential pressure, and ensure DEF supply is maintained. The 500-hour oil change interval and standard Cummins filtration keep routine maintenance straightforward despite the large displacement.

Frequently Asked Questions
What is the standby power rating of the Doosan G570?
The Doosan G570 delivers 500 kW standby and 456 kW prime power. It is the flagship and largest mobile generator in the Doosan G-Series lineup. Also sold as the Bobcat PG570, built in Statesville, North Carolina.
What engine does the Doosan G570 use?
The G570 is powered by a Cummins X15 14.9-liter inline-6 turbocharged diesel engine running at 1,800 RPM. The X15 is the same engine platform used in Class 8 heavy trucks, providing one of the deepest parts and service networks of any diesel engine in North America.
What are the service intervals for the Doosan G570?
Oil changes are due every 500 hours or 12 months, whichever comes first. Air filter and fuel filter replacement intervals are 500 hours. Major engine overhaul is specified at 20,000 hours. The X15 requires full Tier 4 Final aftertreatment management including DPF monitoring — maintain load above 30% to ensure proper regeneration.
Is the Doosan G570 EPA compliant?
Yes. The G570 is EPA Tier 4 Final compliant. The Cummins X15 achieves compliance with a full aftertreatment system (DOC, DPF, SCR). Operators should monitor DPF differential pressure and DEF supply, and maintain adequate load to prevent incomplete DPF regeneration cycles.
How does Doosan compare to CAT at the 570 kVA class?
Both operate in the 500+ kVA class with large Cummins engines. The G570 typically prices 15-30% below CAT while using the same Cummins X15 platform — ensuring identical parts availability and service procedures through Cummins distributors. CAT has broader dealer infrastructure, but the X15 is the most widely serviced large diesel in North America.
What control panel does the Doosan G570 use?
The G570 is equipped with Doosan's digital control panel providing auto-start, fault monitoring, voltage/frequency display, runtime tracking, and comprehensive aftertreatment monitoring including DPF soot load, regeneration status, SCR health, and DEF level for the full Tier 4 Final system.
Who services Doosan generators in Northern California?
OnPoint Generators services Cummins X15-powered generators for large commercial and industrial applications in Northern California. The X15's truck-engine heritage means unmatched parts availability, and our technicians are experienced with the Tier 4 Final aftertreatment health monitoring critical for sustained G570 operations.
