Features

Pure sine wave

The built-in electronic unit with microprocessor control monitors the operation of the generator and provides a stable output voltage of 120V 60Hz sinusoidal form, which is suitable for the reliable operation of sensitive electronics.

Dual Fuel

The generator runs on both gasoline and liquefied gas (propane). The scope of delivery includes a gas hose with a reducer for connection to a gas cylinder according to DIN 477. Just connect the generator to the gas cylinder and start the engine.

Versatility of use

You can use generator with both a portable gas cylinder and with a stationary capacity for gas storage (gasholder). Connection has to be made by a certified specialist. The pressure in the supply system must not exceed 16 Bar.

Low noise level

Thanks to a special protective housing, which provides a minimum noise level (LpA 62 dB, 23 ft.), the operation of the device will be as comfortable as possible and will not disturb others.

Economy mode

The ergonomic control panel is equipped with a fuel economy mode switch. This mode reduces fuel consumption by up to 50% at small loads due to lower engine revolutions.

Robust engine

The reliable proprietary K&S engine is characterized by increased wear resistance, long-term and stable operation. K&S engine meets modern emission standards and has a reduced level of harmful substances in exhaust gases, which protects the environment and your health. Generator as well is equipped with CO sensor, which monitors for the accumulation of poisonous carbon monoxide gas around the generator when the engine is running. If increased level of CO gas is detected, the CO Sensor automatically shuts down the engine.

3-in-1 Start Dial

One dial handles the fuel valve, the choke, and electric start — no juggling separate controls in the cold or the dark. Turn, press, running. It's the kind of small design decision that separates a generator you can live with from one you fight.

Ergonomic control panel

Ergonomic control panel is equipped with multifunction LED display, ECO MODE switch, typical 12 V car socket, generator parallel connection output for double power as well as RESET button for resetting the control system (upon tripping of the circuit breaker) and restoring power supply.

High quality alternator

Könner & Söhnen inverter generators are equipped with a robust brushless alternator with 100% copper winding. The high-end compact permanent magnet alternator is housed in a plastic casing and can withstand maximum loads without any damage to ensure long-term and reliable operation of the generator set.

Parallel connection

Parallel connection ensures insreased power. Using a parallel connection device connected to a special socket on the generator, you can pair the generators and connect devices with greater power. It is suitable for all Könner & Söhnen inverter generators which are parallel ready (KS 2000iS CO, KS 2000iHS CO, KS 4000iEHS CO)

Transportation kit

Könner & Söhnen Inverter generators are equipped with a transport system for easy movement. Two wheels and a handle that lifts when the generator is moved ensure comfortable transportation and mobility.

Accessories set

Generator is equipped with additional accessories: spark plug wrench, hosepipe with pressure reducer, PH2 screwdriver 0.24 in (6.0 mm), filling funnel.

**LPG operation reduces generator power by 10%.

*** 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 gasoline. Before the first start, engine oil for four-stroke gasoline engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded gasoline with an octane rating of 87 or higher. t's acceptable to use gasoline with 10% bio-ethanol.

Which Generator Power to Choose?

habe soeben einen KS4000iEG S geliefert bekommen und ausgepackt - leider ist der in der beiliegenden Anleitung erwähnte und im Handbuch auf dem Bedienfeld abgebildete Kraftstoffwahlschalter (11) dort nicht zu finden. Was tun?

Sehr solides Gerät. Der elektrische Anlasser funktioniert gut. ich nutze nur Gasbetrieb. Das Gerät könnte etwas leiser sein. versand hatte gut funktioniert.
