Generac RG08045ANAX 80kW Protector Series Standby Generator Overview
The Generac RG08045ANAX is an 80kW Protector Series natural gas standby generator with WiFi monitoring, producing single-phase 120/240V power. It is aimed at sites that need serious backup capacity in a compact footprint.
The engine is purpose-built in Wisconsin and uses a dual-valve, ultra-low pressure fuel system with proprietary controls that manage performance across temperatures and elevations. True Power technology keeps total harmonic distortion under 5 percent, which suits sensitive electronics and appliances. The specification table lists 80,000 rated watts, 333 rated amps, a 400 amp circuit breaker and a 12V automatic start system. The engine displaces 4,500 cc and turns at 1,800 RPM. Sound is rated at 68 dB, and natural gas use is given as 534 cubic feet per hour at 50 percent load. The cabinet measures 97.4 x 38 x 48.9 inches, and the unit weighs 1,912 pounds. The carton includes the 80kW generator and an owner’s manual, covered by a 5-year limited factory warranty.
