100 kW Tier 4 Final diesel standby/prime generator from Blue Star Power Systems. Volvo Penta TAD581VE 5.13L inline-four with SCR/DPF/DOC, DSE DCP7310 controller, 208-600V.
The Blue Star VD100-04FT4 is a 100-kilowatt EPA Tier 4 Final / EU Stage 5 diesel standby/prime generator built around the Volvo Penta TAD581VE — a 5.13-liter inline-four with full SCR/DPF/DOC triple aftertreatment. This is a current-production active model and the entry point to Blue Star's Volvo Penta Tier 4 Final lineup.
The TAD581VE shares its bore and stroke dimensions with the larger 7.7L TAD851-853GE inline-six, reflecting Volvo Penta's modular engine architecture — the same combustion chamber design scaled from four to six cylinders.
The VD100-04FT4 bridges the John Deere T4F range and the larger Volvo Penta T4F models:
JD80-03FT4 (80 kW, John Deere 4045HFG04 4.5L I-4, Tier 4 Final) — 20 kW less, different engine OEM, smaller DEF tank (3.8 gal). Choose this if 80 kW meets the load study.
VD125-04FT4 (125 kW, Volvo TAD582VE 5.13L I-4, Tier 4 Final) — same engine block, same footprint, 25 kW more. Choose this if 100 kW is marginal for the load study.
The Volvo Penta TAD581VE is serviced through Volvo Penta's industrial dealer channel. The SCR/DPF/DOC system requires periodic DPF ash cleaning (typically every 4,000-5,000 hours) and regular DEF replenishment. The 18.5-gallon DEF tank is a significant advantage over the John Deere models' 3.8-gallon tank — at typical emergency standby usage, DEF replenishment may only be needed annually rather than at each exercise visit. The DSE DCP7310 controller provides DEF level monitoring and aftertreatment status via the standard CAN J1939 interface.#

Frequently Asked Questions
What engine is in the VD100-04FT4?
The Volvo Penta TAD581VE — a 5.13-liter inline-four turbocharged-aftercooled diesel rated 175 HP (131 kWm) at 1800 RPM. The TAD58xVE family shares its bore (4.33 in) and stroke (5.31 in) with the larger 7.7L TAD851-853GE inline-six used in Tier 3 models, but with four cylinders instead of six. EPA Tier 4 Final and EU Stage 5 certified with SCR/DPF/DOC triple aftertreatment.
Does the VD100-04FT4 require DEF?
Yes. The VD100-04FT4 uses a full SCR/DPF/DOC aftertreatment system. DEF consumption is approximately 5.1% of fuel consumption, and the integrated DEF tank holds 18.5 gallons — significantly larger than the 3.8-gallon tank on the John Deere models (JD60/JD80). At full load, the 18.5-gallon tank provides over 50 hours of operation.
How does the VD100-04FT4 compare to the VD125-04FT4?
Both use the same 5.13L Volvo Penta inline-four block and share identical physical dimensions (110 x 60 x 78 in) and weight (4,250 lbs). The TAD582VE (VD125) produces 218 HP versus 175 HP for the TAD581VE (VD100). The VD125 consumes more fuel (8.61 vs 6.99 gph) and has a slightly higher DEF consumption rate (5.9% vs 5.1%). Choose the VD100 if 100 kW meets the load study — the lower fuel and DEF consumption provide meaningful operating cost savings.
What emissions certifications does the VD100-04FT4 hold?
Both EPA Tier 4 Final and EU Stage 5 — the most stringent diesel emissions standards currently in force. The dual certification makes this model suitable for global deployments and the most restrictive US jurisdictions, including California CARB requirements for non-emergency applications.
