Engine-generator Könner & Söhnen KS 3300I 3000 W, 230 V, 7 L fuel tank, 25.5 kg

The Könner & Söhnen KS 3300I engine-generator delivers a rated output of 3000 W at 230 V from a compact inverter platform. Equipped with a 7 L petrol tank and weighing 25.5 kg, this portable generator is built to supply stable AC power where mains are unavailable. The unit incorporates a microprocessor-controlled inverter that provides a pure sine wave 230 V, 50 Hz output suitable for sensitive electronics. A robust EURO V–compliant engine, brushless alternator with 100% copper winding and an ergonomic control panel with multifunction LED display make the KS 3300I suitable for backup power, outdoor worksites and recreational use.

Advantages

The inverter system ensures stable, low-distortion 230 V sinusoidal output for safe operation of electronics and household appliances. The engine meets European quality standards and is designed for long, steady operation. A compact and lightweight design simplifies transport and storage while support feet improve operational stability. The control panel groups useful functions — hour meter, frequency and voltage indicators, overload and short-circuit protection, low-oil sensor, economy mode switch and a reset button — for straightforward monitoring and control.

Suitable for

• Emergency backup power for home appliances and lighting
• Powering tools and equipment at outdoor work sites

How to use

Position the generator on a level, stable surface and ensure the support feet are properly seated. Fill the 7 L petrol tank with the recommended fuel and check oil level before starting. Connect required loads to the appropriate outlets after starting and confirming stable 230 V output on the display. Use the economy mode switch to reduce fuel consumption at light loads. For parallel operation, connect matching units using the designated parallel connector and follow the manufacturer’s guidance. Always follow local ventilation and fuel-handling safety practices when operating the generator.

Usage recommendations

Use the pure sine wave inverter output for sensitive electronics and medical devices. Regularly inspect oil and fuel levels, and perform scheduled maintenance to ensure long-term reliability. Avoid running the unit in enclosed or poorly ventilated spaces; operate outdoors or in well-ventilated areas with exhaust directed away from people. When storing for extended periods, drain fuel or use fuel stabilizer and follow the maintenance schedule in the user manual.
