Powered by a Generac 816cc EFI (Electronic Fuel Injection) engine, it delivers 18,000 running watts and 22,500 starting watts - enough to keep your home running through extended outages or handle the most demanding jobsite loads. The EFI system optimizes fuel delivery for peak efficiency, providing up to 9 hours of runtime at 50% load from its 14.2-gallon tank.\n\u003c\/p\u003e\n\u003cp\u003e\nSafety is built into every layer of this machine. Onboard COsense Technology continuously monitors carbon monoxide levels and automatically shuts the generator down if dangerous CO is detected, protecting you and your family. TruePower Technology keeps output clean with less than 5% total harmonic distortion (THD), making it safe for sensitive electronics, appliances, and tools. Add in hassle-free electric start with an included battery, heavy-duty never-flat wheels, and a hardened steel tube cradle, and you have a generator built to work as hard as you do.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e18,000 Running Watts \/ 22,500 Starting Watts:\u003c\/strong\u003e Handles heavy loads for whole-home backup power or large jobsite applications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGenerac 816cc EFI Engine:\u003c\/strong\u003e Electronic Fuel Injection optimizes performance and fuel efficiency automatically.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCOsense Technology:\u003c\/strong\u003e Continuously monitors CO levels and shuts the generator down before hazardous carbon monoxide can accumulate - STOPS.
