Overview#
The Generac MD600 is a 600 kW modular diesel standby generator system powered by a Perkins 18.1-liter turbocharged and aftercooled inline-six engine. Part of Generac's Modular Power System (MPS) platform, the MD600 is factory-configured with integrated paralleling controls for plug-and-play scalability. The Perkins 18.1L engine platform is shared with the SD600 and SD750, providing a well-proven foundation in the 600-750 kW power class.
Two MD600 modules provide 1,200 kW of total capacity with N+1 redundancy -- comparable to an SD1250 but with the ability to service one unit while the other continues providing backup power. The modular approach also simplifies transportation and rigging compared to megawatt-class single-engine gensets. The MD600 is well-suited for data center, healthcare, and campus environments where uptime requirements demand redundant power architectures.
Our Service Experience#
The MD600 shares the Perkins 18.1L platform with the SD600 and SD750, a well-known engine in our service territory. At 600 kW per module, fuel logistics and ventilation planning for multi-unit installations are important engineering considerations. We recommend independent load bank testing of each module annually, in addition to parallel operation testing, to verify that every unit can independently carry its rated load. Coolant system monitoring is particularly important on the 18.1L platform at higher output ratings.
