EV4100i Premium 4kW Gasoline Open Frame Inverter Generator
High-Output Inverter Power for Jobsite & Commercial Applications
Product Introduction
Not every job requires a fully enclosed inverter generator. For contractors, equipment operators, farms, and commercial users, maximum power output, easy maintenance, and long working hours are often more important than compactness. The EVOX EV4100i 4kW Open Frame Inverter Generator is engineered specifically to meet these professional requirements.
Powered by a robust 225cc four-stroke OHV gasoline engine, the EV4100i delivers 4.0kW rated output and 4.05kW maximum output, providing dependable inverter power for demanding work environments. Unlike conventional open-frame generators, the EV4100i combines the rugged durability of a traditional generator with the clean electricity produced by advanced inverter technology, making it suitable for both heavy-duty equipment and sensitive electronic devices.
The generator features a large 12-liter fuel tank, allowing extended operation throughout the working day with fewer refueling interruptions. A premium multifunction LCD display provides real-time operating information including voltage, frequency, running hours, maintenance reminders, and generator status. For improved convenience, an optional electric start system is available.
Designed for professional users who require dependable performance, easy serviceability, and high-quality electrical output, the EV4100i delivers an ideal balance between industrial durability and modern inverter technology.
