Inverter Generator Evolution KS 3500iS

The Evolution Technology Platform combines a modern design developed in collaboration with Italian designers, a compact body, premium component quality and thoughtful ergonomics. The upgraded engine with extended service life and enhanced cooling system support stable generator operation even under prolonged loads. All key components undergo internal quality inspection and are carefully selected to ensure generator reliability and durability.

Rubber-tipped corners and an impact-resistant enclosure minimise the risk of damage during transport and active use, helping to extend the generator’s service life even in demanding conditions. Anti-vibration rubber feet firmly secure the generator on a surface, prevent it from shifting during operation, effectively dampen engine vibrations and further reduce noise levels. Thanks to its compact dimensions, well-placed handle and low weight, the generator is easy to transport and store, and its design allows it to be moved by one person. 

Pure sine wave inverter technology provides stable, high-quality power, allowing connection of sensitive electronics — laptops, smartphones, routers and TVs — as well as household appliances including refrigerators, heating boilers, lighting and small power tools. The high-quality brushless alternator with 100% copper winding and permanent magnets combines compactness and reliability, ensuring stable operation of the generating set. This makes the model a versatile solution for leisure, outdoor work and backup power during outages, where output voltage quality is especially important.

Quiet operation and fuel savings are provided by the fully enclosed sound-insulating enclosure and Economy Mode. It automatically adjusts engine speed according to load, reducing fuel consumption and noise levels. At low loads this helps use fuel more efficiently and extend the generator’s run time on a single tank. 

The well-thought-out fuel system improves convenience and safety of operation. A dedicated ON/OFF valve on the fuel tank cap helps prevent accidental fuel leakage during transport and provides the necessary air access during engine operation. The fuel drain zone collects accidentally spilled fuel around the filler neck and prevents it from entering the enclosure near hot engine parts, reducing the risk of fire.

Parallel connection allows two compatible inverter generators to be linked to increase total power output when electricity demands grow. This is a practical solution for users who need extra power without switching to a larger generating set.

Engine protection and convenient control are provided by built-in overload and low oil monitoring systems. The magnetic oil dipstick captures fine metal particles generated during engine operation, helping reduce component wear and extend engine life. . The AC RESET button allows the monitoring system to be restarted and voltage supply to be restored after a protection event without complex actions.

The intuitive control panel with a digital LED display shows voltage, frequency and accumulated engine hours. The operating status, overload and low oil indicators help monitor generator operation, while the load and fuel level indicators allow tracking of current power usage and remaining fuel in the tank so refuelling can be planned in time.

Convenient adapter-free connection is provided by two Schuko 230 V 16 A outlets with overload and short-circuit protection, plus two USB ports for charging mobile devices: Type-A with fast charging QC3.0/4.0 and Type-C with 25 W Power Delivery. This allows household appliances to be connected and compatible gadgets to be charged simultaneously.

KS 3500iS Evolution is a portable inverter generator that combines compactness, quiet operation, economical fuel use and well-engineered solutions. It will serve as a practical power source at home, in the workshop, during travel and outdoors whenever reliable power is needed without access to the mains grid.
