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.

Multifunction Engine Switch 3-in-1

Universal engine switch for the easiest and most convenient start of the generator combines the functions of a fuel valve, an air choke, and an electric engine start

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?

Good

Good value and convenient enough to power essentials in an outage, quiet, portable.

Top device

Used it for a remote outdoor party. It ran speakers, string lights, and a blender without any trouble. Very portable and reliable.

Dual-fuel must

The dual-fuel generator was what sold me. I hesitated on the cost, honestly, thinking it was too much for something I might use three times a year. But the peace of mind... that’s what you pay for. Switching to propane is straightforward when you run dry of gas. It's surprisingly quiet, too; I keep it out in the yard, and it doesn't wake up the whole neighborhood. I worried it would be too complicated for me to manage, but the instructions were actually quite clear. Anyone on the fence about paying a bit more: do it for the flexibility of the fuel. That’s the real value.
