Könner & Söhnen Inverter Generator KS 5500iES ATSR
The KS 5500iES ATSR from Könner & Söhnen is a compact, low-noise inverter generator that produces a pure sine wave output for reliable operation of sensitive electronics. It features a robust, EURO V-compliant K&S engine with Economy Mode (fuel saving up to 50%), a copper-wound alternator for durability, and a clear LED display to help monitor performance and plan maintenance.
Features
PURE SINE WAVE
The built-in electronic unit with microprocessor control monitors generator operation and provides a stable 230 V 50 Hz sinusoidal output, suitable for reliable use with sensitive electronics.
ROBUST ENGINE
The Könner & Söhnen engine is built for increased durability and stable long-term operation, meeting European quality standards including EURO V.
ECONOMY MODE
The control panel includes a fuel-saving mode switch. At low loads this reduces engine speed and can cut fuel consumption by up to 50%.
AUTOMATIC TRANSFER SWITCH
The ATS unit automatically starts the generator and transfers the load when the mains fails, then stops the generator when power is restored. The ATS output uses a 7-pin connector for the KS ATS 4/25 Inverter.
ERGONOMIC CONTROL PANEL
Convenient layout of all functions: multifunction LED display (hour meter, frequency, voltage), operating-mode indicator, overload and short-circuit protection, low-oil sensor, Reset button to restore voltage supply, connector for parallel connection, two USB outputs (5V/1A, 5V/2.1A), 230 V socket and earth terminal.
LOW NOISE LEVEL
The special protective housing helps keep noise to 70 dB, making operation as comfortable as possible without disturbing others.
HIGH QUALITY ALTERNATOR
Könner & Söhnen inverter generators use a robust brushless alternator with 100% copper winding. The compact permanent-magnet alternator is housed in a plastic casing and withstands high loads for long-term reliable operation.
PARALLEL CONNECTION
Connect two generators in parallel (cable included) to increase total output for more powerful devices. The combined output equals the sum of the rated powers of the connected models.
ACCESSORIES SET
Included accessories: spark-plug wrench, filling funnel, parallel-connection cable, and PH2 screwdriver 6.0 mm.
