Overview#
The Generac SD060 is a 60-kilowatt industrial diesel standby generator powered by an Iveco/FPT 4.5-liter turbocharged inline-four engine. Rated at 60 kW standby and 54 kW prime, the SD060 marks the transition from Generac's smaller proprietary engine platform to the larger Iveco/FPT 400-series four-cylinder. This engine upgrade brings a significantly larger crankcase capacity (13.6 qt), a belt-driven water pump design, and a 2,538 RPM fan speed -- all indicating a more robust cooling system suited to higher output. The generator is EPA Certified for Stationary Emergency applications.
Generac pairs the Iveco 4.5L with their K0060124Y21 alternator featuring Class H insulation and brushless excitation. The Digital H control panel provides NFPA 110 Level I and II programmable operation, Modbus communications, and a 7-day programmable exerciser. The engine block heater is standard equipment on the SD060, as is the closed coolant recovery system.
At 60 kW, this unit serves larger commercial standby applications: hotels, light manufacturing, larger medical offices, full-service restaurants with extensive HVAC, and medium-size retail facilities. The single-phase 120/240V configuration at 250 amps provides substantial capacity for larger single-phase services.

Our Service Experience#
The Iveco/FPT 4.5L engine in the SD060 and SD080 is a dependable mid-size diesel platform with a good track record in standby applications. The belt-driven water pump design requires regular belt inspection -- we check the belt condition and tension at every annual service visit, as belt failure in standby service is easily preventable but catastrophic if missed. The crankcase capacity of 13.6 quarts (nearly double the 3.4L engine's 7.4 qt) makes oil changes take longer but also means oil quality holds better over extended intervals.
Sub-base tank options for the SD060 go up to 589 usable gallons, providing over 120 hours of runtime at full standby load. For longer runtime requirements in critical applications (72+ hours specified by NFPA 110 Class 120), the larger tanks are worth specifying at project time rather than adding later.
Frequently Asked Questions#
What enclosure options are available for the SD060? Weather-protective and Level 1/Level 2 sound-attenuated enclosures are available in both steel and aluminum. The Level 2 sound-attenuated enclosure (111.8 x 40.5 x 68.6 in no-tank configuration) is the most common choice for urban commercial installations subject to local noise ordinances. IBC seismic certification is an available engineered option.
Can the SD060 support large motor loads? Yes. With alternator upsizing to the K0100124Y21, the SD060 can support 227 sKVA of motor starting load at 277/480 VAC with a 30% voltage dip. This covers most HVAC compressor starting scenarios in the 60 kW commercial range. Consult load calculations for facilities with multiple large motors starting simultaneously.
How does the SD060 compare to the SD080? Both use the Iveco/FPT 4.5L inline-4 engine. The SD080 is tuned to 80 kW standby, has a slightly higher exhaust temperature, and weighs more. Both share the same general footprint and enclosure options. The SD080 provides 33% more standby capacity for applications where 60 kW is insufficient.
