Overview#
The Generac SD010 is a 10-kilowatt industrial diesel standby generator powered by a Perkins 2.22-liter turbocharged inline-four engine. Rated at 10 kW standby and 9 kW prime, it is the entry point of Generac's industrial diesel lineup and is EPA Certified for Stationary Emergency applications. The generator is available in both single-phase (120/240 VAC) and three-phase configurations across voltages from 120/208V to 346/600V, making it suitable for a wide range of small commercial and light-industrial standby applications.
Generac pairs the Perkins engine with their own K0025124Y21 alternator featuring Class H insulation and synchronous brushless excitation. The Digital H control panel provides NFPA 110 Level I and II programmable operation, Modbus communications, and a predictive maintenance algorithm. The package ships with a factory-filled engine coolant heater as standard, supporting reliable starting across ambient temperature conditions.
The SD010 is configurable with weather-protective or sound-attenuated enclosures in both steel and aluminum, sub-base fuel tanks ranging from 54 to 300 usable gallons, and a variety of circuit breaker options. At 10 kW, this unit typically serves small retail stores, restaurants, offices, and municipal facilities that require code-compliant standby power without the footprint or cost of a larger unit.

Our Service Experience#
The SD010 sees frequent use in small commercial installations throughout Northern California -- neighborhood retail, food service equipment rooms, and small municipal facilities where 10 kW is sufficient to cover emergency lighting, point-of-sale, and HVAC controls. At 1.1 gph full-load fuel consumption, tank sizing is straightforward even for extended outages. The Perkins 2.22L engine is a proven industrial platform with wide parts availability.
Routine maintenance on the SD010 follows standard Generac diesel practice: verify the engine coolant heater (standard equipment) is functional before cold-weather season, maintain the 50/50 ethylene glycol coolant mix, and exercise the unit weekly via the 7-day programmable exerciser. The distribution injection pump on this engine requires clean, low-sulfur diesel -- diesel polishing is recommended for installations where the tank sits idle for more than 6 months between tests.
Frequently Asked Questions#
What is the maximum ambient temperature for the SD010? The SD010 is rated for operation at up to 122°F (50°C) ambient temperature at full standby load. Above that threshold, derating applies per Generac Bulletin No. 0199280SSD. For high-ambient installations such as desert climates or mechanical rooms with limited ventilation, consult a Generac Industrial dealer for site-specific derating factors.
Does the SD010 meet NFPA 110 requirements? Yes. The Digital H Control Panel is programmable for NFPA 110 Level I and Level II compliance. Specific installation requirements -- transfer switch timing, maintenance intervals, load bank testing frequency -- must be documented per NFPA 110 and are the responsibility of the facility's AHJ-approved service provider.
Can the SD010 run on biodiesel? Generac specifies Ultra Low Sulfur Diesel (ASTM D975) for the SD010. Use of biodiesel blends above B5 should be confirmed with the local Generac Industrial dealer before commissioning, as blend compatibility affects fuel system components and engine warranty terms.
