What engine does the VD300-04FT4MP use?

The Volvo Penta TAD1383VE — a 12.8-liter, six-cylinder turbocharged and charge-air-cooled diesel. The TAD1383VE is the higher-output calibration of the 12.8L VP platform shared with the VD250-04FT4MP (TAD1381VE). Both engines share the same block, cylinder count, and displacement; the 1383 calibration produces 300 kWe through higher fuel delivery and boost. EPA Tier 4 Final and EU Stage 5 dual certification applies. The 18.5-gallon DEF tank is shared across the VD100 through VD300 mobile range. Rated power is available to 4,921 ft (1,500 m) at 122°F (50°C).

Is the VD300-04FT4MP available in single-phase output?

No. The VD300-04FT4MP is three-phase only — available in 120/208V (3Ø) and 277/480V (3Ø) configurations. Single-phase 120/240V output is not available at 300 kWe in the Blue Star mobile T4F VD series. The VD250-04FT4MP is the last model in this lineup to support single-phase output. Loads requiring single-phase above 250 kWe from this product line require a transformer or a different product.

How does the VD300-04FT4MP compare to the VD250-04FT4MP on the same 260 × 92 in platform?

The VD250 (TAD1381VE, 15,400 lbs, 17.3 gph, S4L1D-D41) and VD300 (TAD1383VE, 15,700 lbs, 21.1 gph, S4L1D-E41) are footprint-compatible — same 260 × 92 × 124 in trailer — but diverge in phase capability: VD250 supports single-phase, VD300 does not. The weight difference is 300 lbs. The 50 kWe gain costs approximately 3.8 gph at full load. Both share the 350-gallon fuel tank and 18.5-gallon DEF tank. The S4L1D-E41 alternator in the VD300 is the E-wind variant of the S4L1D frame, one step above the D41 in the VD250.

What are the fuel capacity and runtime of the VD300-04FT4MP?

The 350-gallon integral fuel tank at full load (21.1 gph) provides approximately 16.6 hours of runtime. At 75% load (16.6 gph), runtime extends to approximately 21 hours. The 18.5-gallon DEF tank needs refill approximately every 17 hours at full load. Combustion air draw is 931 CFM; ventilation requirement is 13,074 CFM; heat rejected to coolant is 582,660 BTU/hr; exhaust exits at 893°F at 1,823 CFM. Plan daily fuel and DEF replenishment for around-the-clock deployments.

Overview#

The Blue Star VD300-04FT4MP is a 300-kilowatt EPA Tier 4 Final / EU Stage 5 mobile trailer diesel generator powered by the Volvo Penta TAD1383VE — a 12.8-liter, six-cylinder turbocharged and charge-air-cooled engine. It is the highest-output model on Blue Star's 260 × 92 in mobile trailer platform and the maximum output available from the TAD1383VE in this product line.

Blue Star Power Systems pairs the TAD1383VE with a Stamford S4L1D-E41 alternator and DSE DCP7310 controller, mounted on an aluminum road trailer with a 350-gallon integral fuel tank and 18.5-gallon DEF tank. At 15,700 lbs, the VD300-04FT4MP is three-phase only — no single-phase output option exists at this output level in the mobile T4F lineup. The next step up is the VD550-04FT4MP, which moves to the larger 334.5 × 99.5 in trailer platform with a 550-gallon fuel tank.

Three-Phase Only at 300 kW#

The VD300-04FT4MP is three-phase only. Unlike the VD250 below it (which supports 120/240V single-phase), the VD300 is available only in 120/208V and 277/480V three-phase configurations. This is an important planning distinction for applications with any single-phase load requirements. If 120/240V single-phase is needed at or near 300 kWe, a step-down transformer or a different product specification is required.

Platform Ceiling on the 260 × 92 Trailer#

The VD300-04FT4MP is the maximum output available on the 260 × 92 in trailer class. The VD550-04FT4MP steps up to the 334.5 × 99.5 in trailer with the TWD1682GE engine (16.12L, I-6) and a 550-gallon fuel tank — representing a substantial increase in trailer size, weight (24,750 lbs vs 15,700 lbs), and fuel capacity. If load requirements sit between 300 and 550 kWe, there is no intermediate model in the mobile T4F VD series.

When to specify the VD300-04FT4MP#

270–300 kW three-phase temporary or standby power at industrial, construction, municipal, or healthcare sites
Maximum output from the 260 × 92 in Blue Star mobile trailer class
Sites up to 4,921 ft elevation at ambient temperatures to 122°F
Applications requiring EU Stage 5 dual certification at 300 kWe
Projects where the 334.5 × 99.5 in VD550 trailer is too large and 300 kWe satisfies the load requirement

Our service experience#

The TAD1383VE running at 300 kWe full load consumes 21.1 gph — plan fuel logistics accordingly for 24-hour deployments (approximately 500 gallons per day). The 18.5-gallon DEF tank requires daily attention at this consumption rate. Exhaust temperature of 893°F is on the higher end for this platform; ensure exhaust connections and flex connectors are rated appropriately. DPF regeneration is generally reliable at this load density. Annual full-load testing and Volvo Penta T4F/Stage 5 aftertreatment inspections are required maintenance items.
