Features

The KS 5500iES ATSR petrol inverter generator of the German brand “Könner & Söhnen” is a convenient and compact source of electric power with a low noise level. 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 5. 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 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.

Robust engine

The Könner & Söhnen reliable engine is characterized by increased durability, long and stable operation, and meets all European quality standards, including EURO 5.

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.

Automatic transfer switch

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. The ATS output features an 7-pin connector for connecting the ATS unit KS ATS 4/25 Inverter.

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.

Low noise level

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.

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, PH2 screwdriver 6.0 mm, 32 А CEE plug.

*** 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.

Which Generator Power to Choose?

I overloaded it once. The protection cut in fast, and I learned to balance loads better. Quick press and it was back.

I use it in my small repair shop. Customers don’t even notice when the main power goes off. It came with all the plugs I needed. No extra shopping trip, which I appreciate.

My laptop and TV never flicker on this generator. With the old one, I was scared to connect them.

Bought it for my house. Noise was my biggest fear but neighbors never complained. The copper winding was a selling point for me. I’d had bad luck with cheaper models burning out. This one feels built to last.
