Overview#

The Gillette SP-960 is a 96-kilowatt stationary natural gas (80 kW LPG) standby generator — a made-in-USA alternative to the Kohler KG100 and Generac SG series for commercial gaseous backup. It uses a PSI (Power Solutions International) 8.8L V8 engine with a Stamford alternator and Deep Sea Electronics DSE 7420 MKII controller — all industry-standard components rather than proprietary OEM platforms.

Gillette's value proposition is name-brand componentry from open-architecture suppliers (PSI, Stamford, DSE) assembled in the USA. For facilities that prefer non-proprietary parts and service, the SP-960 is a legitimate option.

The PSI engine platform#

PSI (Power Solutions International) specializes in industrial spark-ignition engines for the stationary power market. Their 8.8L V8 is purpose-built for generator duty:

  • Industrial governor with isochronous frequency regulation
  • Designed for natural gas and LP (not converted from diesel or automotive)
  • Electronic fuel injection for consistent air/fuel ratio across load range
  • Catalytic converter compatible for sites requiring additional emissions control

Why consider Gillette#

  • Name-brand components: PSI engine, Stamford alternator, DSE controller — all serviceable by any qualified technician (not locked to OEM-specific dealer network)
  • Made in USA: assembled and load-tested in Elkhart, Indiana
  • UL 2200 listed, configurable for NFPA 110 Level 1
  • THD: Gillette publishes max 3.5% total harmonic distortion (per submittal spec sheet)

Our service experience#

We encounter Gillette units less frequently than Kohler in our territory but they're serviceable with standard tools and readily-available parts. The PSI engine is well-documented and the DSE 7420 MKII controller is the same platform we see across many brands. The main consideration: parts inventory is not as immediately available as Kohler (no local dealer), so we recommend customers keep critical spares on-site (spark plugs, oil filters, battery).

Estimate runtime for the Gillette SP-960

Adjust load percent and tank size to estimate runtime. Pre-filled with this model's spec where available.

Estimate runtime on this tank

Fuel demand at 75% load

1,008,000 BTU/hr1008.0 cf/min @ 1,000 BTU/cf

On utility natural gas the runtime is generally unlimited provided the supply line and meter can deliver this BTU/hr at the engine's required inlet pressure (typically 5–14" WC residential, up to 5 psi commercial). Confirm against the OEM's published fuel-pressure spec.

Frequently Asked Questions

What is Gillette Generators?
Gillette is a US manufacturer (Elkhart, Indiana) that has built generators for over 60 years. They use industry-standard name-brand components (PSI engines, Stamford alternators, DSE controllers) assembled and load-tested in their facility. They compete in the commercial gap between residential brands (Generac) and premium OEMs (Kohler, Caterpillar).
How does the SP-960 compare to Kohler KG100?
Both are ~100 kW gaseous standby units at 1800 RPM with similar architectures. The SP-960 uses a PSI 8.8L V8 (vs Kohler's turbocharged I-6). The tradeoff: Kohler has a larger dealer network and parts ecosystem in Northern California.
What controller does the SP-960 use?
Deep Sea Electronics DSE 7420 MKII — an industry-standard auto mains failure controller with Modbus communication, digital metering, event logging, and remote monitoring capability. Same controller platform used across many generator brands.
Is the SP-960 NFPA 110 compliant?
Yes — the SP-960 is UL 2200 listed and configurable for NFPA 110 Level 1 when supplied with the required alarm contacts, battery monitoring, and fuel supply provisions.
