Overview#
The Generac SG060 is a 60 kW standby industrial natural gas generator set powered by Generac's own 4.5L turbocharged inline-4 spark-ignited engine. Rated at 75 kVA standby at 60 Hz, it is EPA certified for stationary emergency applications and available with a demand response rating. The genset features the Generac Power Zone Pro controller with a 4.3-inch color touchscreen display.
Engine and alternator#
The Generac 4.5L (275 cubic inch) inline-4 turbocharged engine achieves 60 kW standby output at 98 hp and 162 psi BMEP at 1,800 RPM. Key specifications include a 9.1:1 compression ratio, 4.5-inch bore, 4.25-inch stroke, electronic ignition, 5 main bearings, cast iron cylinder head and liners, forged steel crankshaft, and hydraulic roller lifters. Intake and exhaust valves are stainless steel with high steel iron alloy hardened seats. The lubrication system uses a gear-driven oil pump with full-flow spin-on cartridge filtration and a 21-quart (20L) crankcase capacity.
The standard alternator is the Generac K0060124Y21, a 4-pole revolving-field design with Class H insulation on both rotor and stator. It features synchronous brushless excitation, full digital voltage regulation with plus or minus 0.25% steady-state accuracy, and total harmonic distortion below 5%.
Power ratings and fuel consumption#
At 277/480V three-phase and 0.8 power factor, the SG060 delivers 60 kW standby (90 A). Single-phase 120/240V at 1.0 pf produces 60 kW at 250 A.
Natural gas consumption at standby ratings: 795 scfh at 100% load, 601 scfh at 75%, 413 scfh at 50%, and 231 scfh at 25% load.
Physical dimensions#
The open set measures 92.9 x 39.9 x 46.0 inches (2,360 x 1,014 x 1,170 mm), weighing 1,923 to 2,094 lbs (872 to 950 kg). All enclosure levels (Level 0, 1, and 2 sound attenuated) share the same 120.8 x 40.5 x 69.0 inch footprint.
Our service experience#
The 4.5L turbocharged inline-4 in the SG060 runs at a high BMEP of 162 psi. This puts greater thermal load on the valve train. Exhaust temperature reaches 1,338 degrees F at rated output, requiring careful exhaust system design. Spark plug replacement at 1,000-hour intervals and turbocharger condition checks starting at 10,000 hours are the key maintenance milestones. The demand response option is available for facilities seeking to participate in utility peak reduction programs.
