The GENMAX GM4600iAEFIC features an EFI system, which is powered by a 159cc 4-stroke OHV engine. It produces 4600 starting watts and 3800 running watts of clean power, with less than 3% THD. Compared to carburetor generators, EFI systems offer several advantages such as improved efficiency, cleaner emissions, and refined performance. This generator is parallel compatible (kit sold separately), and 50A/240V ready. Additionally, the GM4600IAEFIC meets requirements for EPA, CARB2024, and UL2201 regulations.
