Hahn & Sohn H IG 4200 G ATS inverter generator

The Hahn & Sohn H IG 4200 G ATS is a professional inverter generator designed for demanding users who require reliable performance, stable voltage, and the option of automatic backup operation.

• Thanks to inverter technology, it produces a clean and stable output suitable even for sensitive electronics (control units, computers, boilers, pumps, communication equipment). The rated output is 3.8 kW, with a maximum output of up to 4.2 kW (gasoline), allowing it to power more demanding appliances.
• A major advantage of this model is the ATS connector, enabling connection to an automatic transfer switch. In the event of a power outage, the generator can automatically start and take over power supply to the building (when properly installed by a qualified technician).

The 181 cm³ engine operates in ESC (Economy Smart Control) mode, adjusting engine speed according to the current load. The result is:

• lower fuel consumption

• quieter operation

• longer engine lifespan

The 7.5-liter fuel tank ensures extended runtime without frequent refueling. Starting is handled by electric start (push button) with a backup manual recoil start.

The robust enclosed design with transport wheels and a telescopic handle ensures easy handling. A weight of approximately 30 kg allows relatively convenient transport even by one person.

This model is ideal as:

• backup power source for a family home

• power supply for construction equipment

• energy source for service vehicles

• solution for caravans and mobile use
