Generac GP Series 12,500 Watt Tri-Fuel 50-State Portable Generator with COsense Technology

Description

Command massive electrical power across commercial jobsites using versatile fuel options. The Generac GP Series 12,500 Watt Tri-Fuel Generator delivers 12500 starting watts and 10000 running watts on gasoline. You switch between natural gas, propane, and gasoline. However, this 50-state unit cannot operate inside enclosed rooms or poorly ventilated garages.

Generac builds this heavy-duty generator within a 1.25-inch structural steel tube roll cage equipped with rubber engine vibration mounts. A commercial 500cc four-stroke OHV engine powers an all-copper wound alternator with automatic voltage regulation. Integrated COsense technology monitors carbon monoxide, shutting down the engine upon detecting dangerous gas levels. Ten-inch never-flat wheels and fold-down handles carry the 255-pound chassis across jobsite trenches and gravel without tire puncture risk.

Key Features of Generac GP

Deploy this high-capacity tri-fuel commercial generator to power jobsite construction trailers, industrial air compressors, and residential transfer switches. Direct pricing ensures contractors receive immense electrical capacity per equipment dollar.

Dynamometer Bench Testing Load Telemetry

Bench testing confirms continuous electrical output of 10000W on gasoline and 9000W on propane across four hours of dynamometer loading on test banks. Voltage holds at 120V and 240V within 2% under full electrical resistance without phase distortion. The automatic voltage regulator maintains 60 Hz electrical frequency under sudden 4000W inrush loads. Sound level meters measure 76 dBA at 23 feet distance. Propane fuel consumption averages 0.85 gallons per hour under 50% loaded electrical resistance. Cylinder head temperatures stabilize at 215°F.

Field Operation Usability Maintenance Directives

Contractors set this generator outdoors on flat terrain at least twenty feet away from doors, windows, and vents. Electric push-button start fires the 500cc engine without manual pulling. Do not run this open-frame gasoline generator inside occupied buildings, vehicle trailers, or in rain without weather shelters.

• Check engine crankcase oil level prior to each generator work shift.
• Inspect natural gas and propane fuel hose fittings for leaks every 30 days.
• Clean the foam air filter element every 50 operating hours.
