The KS 5500iEG S LPG/gasoline inverter generator of the German brand “Könner & Söhnen” is a convenient, compact and almost noiseless source of electric power. One of the main features of this model is that it produces electric current with the pure sine wave.

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%. Alternator with copper winding and high-performance K&S engine guarantee trouble-free and long-term operation and meet all European quality standards. The LED display makes it possible to monitor the operation of the generator and to carry out its maintenance in time.

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.


Thanks to a special protective housing, which provides a minimum noise level of 66 dB, the operation of the device will be as comfortable as possible and will not disturb others.


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

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, connector for parallel connection of generators, two USB outputs (5V/1A, 5V/2.1A), 230 V socket 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.

Parallel connection

Possibility of parallel connection of two generators for increased total output and possibility of use of more powerful devices. With a cable for parallel connection, which is in a set, you can connect two inverter generators together and get an output power, which is equal to the sum of the rated power of these models.

Accessories set

Generator is equipped with additional accessories: spark plug wrench, filling funnel, parallel connection cable, 16 А Schuko plug, PH2 screwdriver 6.0 mm, 32 А CEE plug.
