Inverter generator 4000W, KS 4000iES ATS, KÖNNER & SÖHNEN

The KÖNNER & SÖHNEN KS 4000iE S ATS Inverter Generator is designed for individual electricity consumers only.

 Featuring a built-in ATS (Automatic Transfer Switch) and can be started manually or automatically. Its OFF-RUN rotary switch integrates fuel, power, and ignition controls. When the generator is not in use, it should remain OFF so that the lithium battery installed in the generator does not discharge. For the initial setup, simply connect the battery under the left side cover.

This generator intelligently manages the power supply, automatically starting up and switching to inverter mode if the MAINS INPUT fails, thanks to its ATS controller. It offers two 230V output sockets for versatile connection options.
Equipped with a durable K&S engine that meets EURO V standards, the generator operates efficiently, with an ECONOMY MODE to cut fuel use by up to 50% at lower loads. Its ergonomic control panel, complete with an LED display and RESET button, allows for easy monitoring and control of operation.

Designed for quiet use at just 66 dB and easy transportation with a built-in kit, this generator is ideal for powering sensitive electronics with its pure sine wave output. The high-quality, brushless alternator with copper winding ensures reliable and long-lasting performance.

Please note: Installation should comply with local regulations and be performed by a licensed electrician. This generator is perfect for individual electricity consumers but is not intended for full household automatic supply in TN systems.
