Overview#
The Generac MD300 is a 300 kW modular diesel standby generator system powered by an Iveco/FPT 10.3-liter turbocharged and aftercooled inline-six engine. Part of Generac's Modular Power System (MPS) platform, the MD300 is factory-configured with integrated paralleling controls that enable plug-and-play scalability. Multiple MD300 units can be deployed together for N+1 or N+2 redundancy, and the system supports mixed configurations with other MD Series units to match evolving facility load requirements.
The modular approach provides significant advantages for mission-critical applications: individual units can be taken offline for maintenance without interrupting backup power, transportation and rigging are simplified compared to a single larger genset, and capacity can be added incrementally as facility loads grow. The MD300 uses Generac's Modular Power System controller for automatic load sharing and synchronization.
Our Service Experience#
The MD300 shares the proven Iveco/FPT 10.3L platform with the SD300, a well-known engine in our service territory. Modular installations require careful attention to paralleling controller calibration during commissioning and at annual service intervals. We recommend exercising each module independently on a staggered schedule to verify that every unit can carry load on its own, in addition to regular parallel operation testing.
