The Stephill SSDK16M is a professional 12.7kW super-silent diesel generator providing 400V, 230V and 115V outputs for construction, industrial, commercial and standby-power applications. Powered by a 1500rpm Kubota Stage V water-cooled engine, it features a Deep Sea DSE3110 controller, brushless AVR alternator and a 120-litre long-run fuel tank.

Stephill SSDK16M 12.7kW Super Silent Multi-Voltage Diesel Generator | Kubota Stage V Engine

The Stephill SSDK16M 12.7kW Super Silent Multi-Voltage Diesel Generator is designed for professional users who require dependable 400V, 230V and 115V power from one robust, enclosed generator.

It delivers a maximum output of 15.9kVA / 12.7kW at 400V and a continuous output of 14.5kVA / 11.6kW, making it suitable for construction sites, industrial premises, workshops, agricultural applications, equipment hire and emergency standby power.

Important Delivery and Offloading Information

Due to the size and weight of this generator, suitable mechanical offloading equipment must be available at the delivery address.

The customer must arrange access to a forklift, telehandler, crane or similar lifting equipment. Offloading equipment and labour are not included with delivery, and the site must provide suitable access for the delivery vehicle.

Kubota Stage V Diesel Engine

The SSDK16M is powered by a professional 1500rpm Kubota water-cooled diesel engine.

Its low-speed configuration supports dependable extended operation, reduced engine wear and lower operating noise. The engine complies with EU Stage V emissions requirements and includes automatic shutdown protection for:

High engine temperature
Low oil pressure

Multi-Voltage Power Output

The generator provides power across 400V, 230V and 115V applications.

At 400V, it delivers:

Maximum power: 12.7kW
Continuous power: 11.6kW

At 230V/115V, it delivers:

Maximum power: 11.9kW
Continuous power: 10.8kW

The fitted socket configuration includes:

1 × 115V 16A
3 × 115V 32A
1 × 230V 16A
2 × 230V 32A
1 × 400V 32A
1 × spurred 230V 16A outlet

This makes the SSDK16M particularly versatile for professional site tools, standard single-phase equipment and compatible three-phase machinery.

Deep Sea DSE3110 Controller

The integrated Deep Sea DSE3110 controller provides straightforward push-button starting and stopping.

A two-wire remote-start facility allows the generator to be activated by compatible external controls or a suitably configured automatic transfer arrangement. The lockable control-panel housing helps protect the controls and prevent unauthorised operation.

Super-Silent Acoustic Enclosure

The generator is housed within a close-fitting acoustic cabinet manufactured from Zintec steel for improved corrosion resistance.

Large access doors provide convenient entry for inspection, servicing and maintenance. The generator produces a stated noise level of approximately 63dB(A) at 7m.

Brushless AVR Alternator

The SSDK16M is fitted with a maintenance-free brushless alternator incorporating Automatic Voltage Regulation.

The AVR system controls output voltage to approximately ±1%, helping provide a stable supply for connected tools, machinery and electrical equipment.

Long-Running 120-Litre Fuel Tank

The integrated 120-litre fuel tank provides up to approximately 34 hours of operation, depending on connected load and operating conditions.

This extended runtime makes the SSDK16M suitable for prolonged site use, remote working locations and standby-power applications.
