Overview#

The Triton Power TP-P400-T3-UL is a 400 kW diesel standby generator built on the Perkins 2206D-E13TAG3 turbocharged and aftercooled six-cylinder engine (12.5 L displacement, bore 130 mm x stroke 157 mm, 16.3:1 compression ratio). It is paired with a Leroy Somer alternator, carries UL2200 listing, and meets EPA Tier 3 for emergency stationary applications. This is a three-phase-only unit available at 277/480V, 120/208V, and 120/240V.

The unit features a Deep Sea Electronics DSE7310 controller with full engine and alternator monitoring, plus USB configuration via DSE PC Suite. Fuel consumption is 93.9 L/hr (24.8 GPH) at full load, dropping to 51.9 L/hr (13.7 GPH) at half load.

Our service experience#

The Perkins 2206D is the 12.5 L platform that powers the 300-450 kW class across multiple generator brands. The TAG3 variant in this unit produces 462 kWm (620 HP) at rated RPM. At 400 kW standby, this unit competes with the Kohler 400REOZJF and Cummins C400D6 but at Triton's value price point. In Northern California, the 400 kW class serves larger commercial buildings, hospitals, and data center edge deployments where reliable backup power is critical but budget consciousness still matters.

Why we recommend Triton Power

Triton Power is our value brand for mobile and portable diesel generators, and an emerging option for industrial standby. When MQ Power's pricing is a stretch or lead times are too long, Triton delivers comparable capability at a lower price point with faster availability.

We are developing our Triton Power sales relationship and building fleet experience. Every engine platform Triton uses — Perkins, John Deere, Kubota, Scania, Volvo — is one we already service daily across other brands. Triton's open architecture means our technicians can maintain these units with standard tooling and widely available parts.
