Hahn & Sohn HDE 18000SA3 diesel generator set
High-performance soundproof diesel generator for single-phase and three-phase operation (230 / 400 V), designed for professional use, industry, and backup power supply for buildings. It offers a rated output of up to 14 kW, a maximum output of up to 15 kW, engine preheating, electric starting, and stable output thanks to AVR regulation.
The diesel generator Hahn & Sohn HDE 18000SA3 represents a robust and powerful source of electrical energy in a soundproof (silent) enclosure, designed for demanding operations where high power reserve, reliability, and low noise levels are essential.
- The generator supports single-phase operation at 230 V as well as three-phase operation at 400 V. At 230 V, it delivers a rated output of 13.0 kW and a maximum output of 14.0 kW. At 400 V, it reaches a rated output of 14.0 kW and a maximum output of 15.0 kW, making it suitable for powering high-performance three-phase machines, technologies, and entire facilities.
- Stable output voltage is ensured by automatic AVR voltage regulation, which protects sensitive equipment against voltage fluctuations. The generator is equipped with electric starting and engine preheating, allowing reliable starts even at low temperatures. Standard features also include protection against overload and low oil level.
- Thanks to the soundproof enclosure, high-quality vibration damping, and optimized airflow, the generator achieves low noise levels, making it suitable for use near residential or commercial buildings.

Automatic Transfer Switch (ATS) – How It Works in Practice
Hahn & Sohn ATS 15 kW / 32 A - indoor
The automatic transfer switch (ATS) is used to automatically start the generator in the event of a power failure, thus ensuring an uninterrupted power supply to selected circuits. As soon as the power supply from the grid is restored, the generator switches off automatically and the power supply switches back to the distribution network.
Thanks to this function, the generator acts as a reliable backup source without the need to manually switch anything on or off.
⚠️ Important note: The ATS switch is not included with the generator and must be purchased separately.
Notice
The product is supplied without engine oil and diesel fuel.
Before first start-up, we recommend adding SAE 10W-30 engine oil and EN 590 diesel fuel.
First oil change after 50 operating hours, then every 100 hours.
Always check the oil and fuel levels before starting.
