Inverter gasoline powered generators are a user-friendly portable source of energy. The range of inverter generators features models with a power range from 1.8 to 8.0 kW. Double conversion of electric energy provides the pure sine wave and frequency of 50 Hz, which ensures reliable operation of sensitive and high-precision electronics.

All models are based on robust engines, which meet all European quality standards, including EURO V. Engines of K&S inverter generators have an Economy mode, which allows using the generator at low speeds and reduces fuel consumption by up to 50%.

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.


The Könner & Söhnen reliable engine is characterized by increased durability, long and stable operation, and meets all European quality standards, including EURO V.


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.


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.

The ATS (Automatic transfer switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected.

Gasoline and diesel generators with an electric starter are equipped with a 8-pin connector for an automatic transfer switch unit (ATS input). The ATS unit has a PLC that allows the automatic start/stop of the generator to be programmed in the event of a power outage and after its restoration.


  • Automatic/manual operation
  • Programming of engine starting time after power outage
  • Programming of engine warm-up time before connecting to consumer
  • Setting of starter operation time
  • Engine performance monitoring
  • Battery charging when the generator is off

The ATS (Automatic Transfer Switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected and automatically stops the generator when the central power supply is restored.

Ergonomic control panel

Convenient location of all functions: multifunction LED display (hour meter, frequency, voltage), working mode indicator, overload and short circuit protection, low oil level sensor, Reset button to reset the control system and restore voltage supply, two USB outputs (5V/1A, 5V/2.1A), typical 12 V car socket for a wide range of car devices, gadgets and battery charging, 230 V sockets and grounding terminal.

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.

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.
