Generac SG040-NG 50kVA Natural Gas Generator with Level 2 Enclosure (3 Phase)

The Generac SG040-NG 50kVA Natural Gas Generator with Level 2 Enclosure is a powerful, fully automatic standby generator designed for medium to large commercial and industrial facilities. Powered by clean-burning natural gas, it delivers 50kVA (40kW at 0.8 PF) of reliable 3-phase power at 400/230V 50Hz — ideal for protecting critical loads in offices, warehouses, workshops, small data centres, retail complexes, or manufacturing sites during power outages.

The Level 2 sound-attenuated canopy reduces noise to approximately 65-68 dB(A) at 7m, making it suitable for urban or noise-sensitive environments.
