50kW Diesel Generator SD050



Alternators are as important to power generation as engines. Generac's in-house built alternators are machine wound, machine inserted, and machine varnished for the ultimate in consistency.

Available in single-phase or three-phase, the 50kW industrial diesel generator set provides 60-208amps of power. There are open set, standard enclosure, or Level 1 or 2 acoustic enclosure options. Made with a 4 cylinder engine, it features a digital H control panel. 50kW generators have the power to backup essential equipment in small industrial or commercial buildings.

  • Generator Enclosure: Generac manufactures its own enclosures, ensuring each unit combines the highest level of durability, noise reduction, weather resistance, and streamlined design.
  • Industrial Alternator: Generac industrial alternators are machine wound, machine inserted, and machine varnished for the ultimate in consistency.
  • PowerManager® Controller: Generac engineers its generator controls with safety and convenience as top priorities.
