Generac GP9500E Tri-Fuel Portable Generator – 12,500W Gas/11,250W Propane/9,000W NG with Electric Start & COsense – G0080631

The Generac GP9500E Tri-Fuel (Model 8063) is built for homeowners, contractors, and outdoor enthusiasts who need maximum power with the freedom to choose their fuel source. Running on gasoline, liquid propane, or natural gas, this generator adapts to what is available — whether that is a 20 lb propane tank in a storm or a dedicated natural gas line for long-duration backup. Reliable power for the loads that matter most .

Why Choose Generac GP9500E?

With 9,500 running watts and 12,500 starting watts on gasoline, the GP9500E handles refrigerators, sump pumps, window air conditioners, electric furnace blowers, and multiple power tools simultaneously. Built-in Automatic Voltage Regulation (AVR) stabilizes output, protecting connected equipment from voltage fluctuations throughout operation . Fuel flexibility means longer uptime. The 7.5-gallon steel fuel tank delivers up to 9.5 hours of runtime at 50% load on gas, or up to 14 hours at 25% load. Connect to a natural gas line and runtime becomes virtually unlimited — an advantage no single-fuel generator can offer .
