Why buyers choose Blue Star

  • Open controllers — Basler DGC-2020 serviceable with off-the-shelf software, even if Blue Star disappeared
  • Multi-OEM component strategy — John Deere, Perkins, Volvo, Mitsubishi engines + Marathon/Stamford alternators
  • Hand-built custom-to-order — every unit configured to spec, not pulled from warehouse inventory
  • DEUTZ AG ownership — global diesel engine giant backing provides long-term stability
  • UL 2200 / CSA / IBC 2021 seismic certified

Who Blue Star is for

Service-savvy buyers who hate proprietary lock-in, custom configuration requirements, value engineering projects, and independent dealers wanting OEM-agnostic equipment.

What to consider before specifying Blue Star

  • Low brand recognition outside the dealer community
  • Thinner service network than major brands
  • 20+ week lead times for custom-to-order units
  • Ex-Katolight heritage only known to industry insiders

Blue Star occupies a specific niche in the generator market: operators who want full control over every component in their power system and refuse to be locked into a proprietary ecosystem. The Basler DGC-2020 controller at the heart of every Blue Star unit is an open-architecture platform — any qualified controls technician can program it, any independent distributor can supply replacement modules, and the standard communication protocols integrate with third-party building management systems without OEM involvement. For facilities that have been burned by proprietary controller lock-in from Kohler or CAT, that openness is the deciding factor.

Blue Star pairs the open controller with a multi-OEM engine strategy, sourcing from manufacturers best suited to each application's requirements. The DEUTZ acquisition adds the German engine manufacturer's diesel platforms and global parts network to Blue Star's options without eliminating the flexibility to spec alternative engines. Hand-built assembly means each unit can be configured for non-standard voltages, unusual enclosure dimensions, or specific site constraints that the major brands' catalog models cannot accommodate. This custom approach serves a real market — telecommunications companies, remote industrial sites, and municipal utilities frequently need configurations that do not exist in any manufacturer's standard lineup.

The cost of that flexibility is time and scale. Custom Blue Star units require 20 or more weeks from order to delivery, compared to 3-7 days from Gillette or 8-12 weeks from Cummins for standard configurations. Blue Star's dealer and service network is significantly smaller than CAT, Kohler, or Generac, which means emergency service response depends heavily on geography. And for buyers who simply need a reliable standby generator in a standard configuration, Blue Star's custom-build approach adds lead time and cost without delivering proportional value — those buyers are better served by Cummins or Generac.

Frequently asked questions

What makes the Basler DGC-2020 controller an open architecture?
The Basler DGC-2020 is a non-proprietary digital genset controller that any qualified controls technician can program, modify, and replace without OEM involvement. Unlike Kohler's Decision-Maker or CAT's EMCP controllers, the DGC-2020 uses standard communication protocols and is available from independent distributors — eliminating single-vendor lock-in for the life of the generator.
What does the DEUTZ acquisition mean for Blue Star?
DEUTZ, the German engine manufacturer, acquired Blue Star to create a vertically integrated power generation platform. Blue Star units can now be paired with DEUTZ engines while retaining multi-OEM flexibility. The acquisition brings stronger financial backing and parts supply chain depth, though it has not changed Blue Star's custom-build approach or dealer footprint.
Why do custom Blue Star units take 20+ weeks to deliver?
Blue Star generators are hand-built to order rather than pulled from inventory. Custom enclosures, non-standard voltage configurations, and specific engine-alternator pairings all require individual engineering and assembly. For standard configurations, lead times are shorter, but Blue Star's core market — operators who need something the major brands do not catalog — should plan for 20 weeks or more.
