2025 Generac Mobile Stationary Generators SD020

Weather takes its toll, but our factory-made enclosures seal out wind, rain, snow, and other elements that could adversely affect your generator. Our enclosures offer easy access for routine diesel generator servicing, giving you the best of both worlds.

Features may include:

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. It also helps in diesel generator quiet operation.
POWER ZONE® 410? CONTROLLER
  • Generac engineers its generator controls with safety and convenience as top priorities.
