Overview

The STIHL IR 40 Silent Petrol Inverter Generator is a compact, ultra-quiet, high-performance power station designed for residential backup, job sites, mobile workshops, and sensitive electronic devices. Powered by a reliable 149 cc 4-stroke OHV air-cooled engine, it generates up to 2.8 kW of maximum output and 2.5 kW of continuous power. Built with advanced inverter technology, it converts raw power to smooth, stable electricity, ensuring clean power output safe for sensitive electronics such as smartphones, laptops, and precision diagnostic tools.

Engineered for quiet operation and high fuel efficiency, the IR 40 features an intelligent ECO Mode system that automatically scales engine speed to match power demand. At a lightweight 28 kg design with a fully enclosed sound-dampening housing, it operates at low noise levels, making it ideal for noise-restricted environments, outdoor catering, camping, and remote field projects. The intuitive control panel features dual single-phase AC outlets, DC charging ports, oil level alerts, overload protection indicators, and parallel connection capability to double power output when paired with a second IR 40 unit.
