600 kW EPA Tier 2 diesel standby generator from Blue Star Power Systems. Volvo Penta TWD1643GE 16.1L inline-six, 208-4160V output, available with medium-voltage option.
The Blue Star VD600-01 is a 600-kilowatt EPA Tier 2 diesel standby generator. It is a workhorse industrial / large-commercial size — typical for hospital main backup, mid-size data centers, large hotels, manufacturing plants, and high-rise residential. Blue Star packages the same Volvo Penta TWD1643GE engine that Kohler uses on the 600REOZVB and that several other major OEMs build onto in this class.
Standby is rated 600 kWe; prime rating is 550 kWe for unlimited-runtime applications where Tier 2 emissions are still permitted (typically continuous-duty industrial use outside CARB-aligned jurisdictions).
The TWD1643GE is one of the most widely deployed industrial diesels in the 500-700 kW class:
16.12L inline-six — large-displacement, moderate-RPM (1800) design favors longevity over peak power density
Turbocharged with water-to-air aftercooling — supports tight load acceptance steps required for hospital and data center applications
Common across multiple OEMs — shared with Kohler 600REOZVB, MTU, and other system integrators, which means abundant service literature and parts availability through Volvo Penta's industrial channel
This unit's ability to be configured for 4160V medium-voltage output is one of its meaningful differentiators in the 600 kW class. Large healthcare and industrial campuses often distribute at 4160V; coupling the genset directly to the MV bus eliminates a 600V→4160V step-up transformer and reduces the electrical room footprint.
The Volvo Penta TWD1643GE is one of the platforms we know best — it is the same engine on Kohler 600REOZVB units we have serviced for years. The Blue Star packaging is solid: enclosures are well-fabricated, the Basler DGC-2020HD is a known controller platform, and parts cross-reference cleanly to Volvo's industrial catalog. The main consideration in our market is dealer access — Blue Star does not have a Bay Area dealer presence the way Cat and Kohler do, so we recommend customers pre-stage critical spares (filters, glow plugs, alternator controls) on-site.

Frequently Asked Questions
Why does the VD600-01 still use a Tier 2 engine in 2026?
EPA regulations permit Tier 2 diesel engines for stationary emergency standby applications in most US jurisdictions; Tier 4 Final is required for prime / non-emergency / mobile use and for new installations in California and similar CARB-aligned jurisdictions. The VD600-01 is the cost-effective option where Tier 2 is allowed; the VD600-02FT4 is the Tier 4 Final equivalent with SCR aftertreatment.
What is the medium-voltage 4160V option for?
Large industrial campuses, hospitals, and data centers often distribute power at medium voltage (4160V or 13.8kV) to reduce conductor losses across the site. Direct-coupling a 4160V genset to the medium-voltage bus avoids the need for a step-up transformer at the genset, which simplifies the electrical room and reduces installed cost on large jobs.
What controller is on the VD600-01?
The Basler DGC-2020HD — a heavy-duty variant of the DGC-2020 used across the smaller Blue Star line. It supports paralleling, load sharing, and integration with site SCADA via Modbus / RS-485, plus optional cellular and Ethernet for remote monitoring. The HD variant adds the larger-display interface and additional I/O channels appropriate for 600+ kW units.
How does the VD600-01 compare to a Caterpillar 3500 or Kohler 600REOZVB?
All three are 600 kW class Tier 2 diesel sets. The Volvo Penta TWD1643GE is a 16.1L inline-six versus Cat 3500's V12 and Kohler's V8 (also Volvo TWD1643GE-based on the 600REOZVB). Cat has the largest dealer service network in North America. Kohler and Blue Star share an engine platform, so service literature and spare parts are functionally identical between the two — choice often comes down to integrator package, enclosure, and pricing.
