The Generac GP15500EFI Portable Generator delivers high-capacity portable power with 15,500 running watts and 19,300 starting watts. Designed for demanding power applications, this gasoline-powered generator combines Generac's TruePower Technology with an 816cc V-Twin OHVI engine featuring electronic fuel injection (EFI).

The GP15500EFI features COsense automatic carbon monoxide shutdown and an easy-to-use electric start with the battery included. TruePower Technology provides electrical output with less than 5% THD, while the low-oil shutdown system helps protect the engine during operation.

A large 14.2-gallon steel fuel tank provides up to 11 hours of runtime at 50% load. The rugged 1 1/4-inch hardened tubular steel open frame, fold-down locking handles, and 12-inch never-flat wheels provide a durable and portable design for demanding environments.

With 120/240-volt output and multiple receptacles, including 30-amp and 50-amp connections, the GP15500EFI is built to handle a wide range of high-power applications. This model is EPA emissions compliant but not for sale in California.
