4000W Max Open Frame Inverter Generator for Starting Loads & Jobsite Power

Model: EYG4800iO   4000 Peak Watts | 3500 Rated Watts 

A 4000W max open frame inverter generator is ideal for jobsite and field applications that require stronger peak starting power for higher inrush loads—such as power tools, pumps, and certain compressor-driven equipment. The open-frame layout improves service access and routine maintenance, making it well-suited for distributor stocking, rental turnover, and project procurement with lower after-sales workload. Inverter-stable output supports mixed use of tools and electronics in mobile work, events setup, and field service. As a source manufacturer, we provide OEM/private label programs, bulk supply, and market-specific configurations for wholesalers, dealers, and retailers.
