Pure sine wave

The built-in electronic unit with microprocessor control monitors the operation of the generator and provides a stable output voltage of 230V 50Hz sinusoidal form, which is suitable for the reliable operation of sensitive electronics.

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 5 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.

Alternator with 100% copper winding

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.

Accessory kit

Filling funnel and screw-driver are included.

*** Fuel consumption depends on many factors, such as load, fuel quality, season, altitude, technical condition of the generator.

ATTENTION! The product is sold without engine oil or petrol. Before the first start, engine oil for four-stroke petrol engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded petrol with an octane rating of 90–95 containing no more than 10% ethanol.
