Wacker Neuson G150 Mobile Generator Overview
The Wacker Neuson G150 Mobile Generator provides 121 kW of prime power and 130 kW of standby output, with single-phase and three-phase voltage flexibility. It is aimed at large-scale construction, emergency response and industrial backup, with an emphasis on low noise and extended runtime.
A Cummins QSB5-G12 Tier 4 Final diesel engine drives a Mecc Alte brushless generator with an automatic voltage regulator for precise voltage control and stable output. A digital controller with an LCD display monitors performance and protects the engine, and a sound-attenuated housing holds noise to 73 dB(A) at 23 feet.
The 187.6-gallon fuel tank, combined with a DEF system, supports up to 64.5 hours of runtime at 25 percent load, and 20.4 hours at 100 percent load. Receptacles include two 20A GFI duplex outlets and three 50A twist-lock outlets, and two 12V batteries are included. The unit is mounted on an integrated trailer with a pintle coupling, and the table lists the full ratings.
Three-phase voltages range from 208V to 480V and single-phase voltages from 120V to 277V. Rated three-phase prime current is listed as 364 A / 182 A, voltage control holds to plus or minus 0.2 percent in steady state, and the insulation class is H. DEF consumption is 0.38 gal/hr, and the trailer-mounted unit measures 176 x 80 x 91.8 inches with an operating weight of 7,770 lb.
