Pure sine wave

The integrated microprocessor-controlled electronic unit controls the generator operation and provides the most stable frequency of 50 Hz and voltage of 230 V. This makes the generator ideally suited for sensitive and high-precision electronics, electronic measuring instruments, medical devices, heating boilers, etc.

Compact size

The compact size and light weight of inverter generators from K&S Basic make them very user-friendly and easy-to-handle, which allows to expand greatly their field of application. This makes them easy to use and indispensable on a camping trip or on a picnic.

Robust engine

The robust K&S Basic engine meets all European quality standards, including the latest EURO V emission standards. The proprietary robust K&S engine has its own individual serial number, which allows us to control the quality of production and service.


K&S Basic generators are equipped with a high-end synchronous alternator with 100% copper winding. It is only the copper winding that can withstand maximum loads without any damage to ensure long-term reliable operation of the generator set.

Convenient ergonomic control panel

Convenient ergonomic panel allows to operate generator easily and does not demand additional skills. Engines of inverter generators from Könner & Söhnen have an Economy mode. This mode allows using the inverter generator at low speeds and reduces fuel consumption by up to 50%. The air choke control system adjusts the engine speed depending on the load.
