Overview#
The Blue Star VD300-02FT4 is a 300-kilowatt EPA Tier 4 Final diesel standby generator built around the Volvo Penta TAD1373VE inline-six. It sits in Blue Star's mid-large diesel range — a common size for full-service hotels, mid-size hospitals, suburban campuses, manufacturing facilities, and edge data centers.
Blue Star also packages this same engine in a trailer-ready mobile variant (VD300-02FT4MP) for rental fleets and disaster-recovery deployment, sharing parts and service procedures with the stationary model.
The Volvo Penta TAD1373VE#
The TAD1373VE is one of Volvo Penta's industrial Tier 4 Final generator engines. Distinguishing characteristics relevant to a buyer:
- 12.8L inline-six — moderate displacement compared to V8 / V12 alternatives at this kW class, with simpler mechanical service access
- SCR-only aftertreatment — DEF (urea) consumption added to the maintenance plan, but no DPF regeneration to manage under light load
- Common-rail high-pressure injection with electronic engine management
When to spec the VD300-02FT4#
- 250-300 kW continuous standby loads where Tier 4 Final compliance is required
- California and other CARB-aligned jurisdictions for new emergency-standby installations
- Sites that prefer SCR aftertreatment over DPF (less regen risk under light-load exercise patterns)
- Edge data centers and similar 24/7 facilities where prime / continuous duty is needed at the same 300 kWe rating
Our service experience#
The Volvo Penta TAD1373 is well-supported in Northern California through Volvo Penta's industrial dealer channel. The two ongoing Tier 4 Final maintenance items beyond a Tier 2 diesel — DEF replenishment and SCR catalyst monitoring — are predictable and add modest cost. We see this size unit most frequently at edge healthcare and education campuses where 250-350 kW peak load is typical and CARB compliance mandates Tier 4 Final.
