Stephill SSDP50 40.0kW Super Silent Three Phase Diesel Generator | Perkins Engine
The Stephill SSDP50 40kW Super Silent Three Phase Diesel Generator is engineered for demanding applications where dependable power, long running capability and reduced operating noise are essential.
Delivering a maximum output of 50kVA / 40kW and a continuous output of 45kVA / 36kW, the SSDP50 is suitable for industrial premises, commercial buildings, agricultural operations, workshops, construction projects and emergency standby-power installations.
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 will need to arrange access to a:
- Forklift
- Telehandler
- Crane or other suitable lifting equipment
Offloading equipment and labour are not included with delivery. The delivery location must also provide suitable access for the transport vehicle.
Super-Silent Acoustic Enclosure
The SSDP50 is housed within a close-fitting acoustic cabinet designed to reduce operating noise while protecting the generator’s internal components.
The enclosure is manufactured from Zintec steel, providing excellent resistance against corrosion and demanding outdoor conditions. Large access doors allow convenient entry for inspection, servicing and routine maintenance.
With a noise level of approximately 63dB(A) at 7m, the generator is suitable for applications where lower operating noise is important.
Perkins Water-Cooled Diesel Engine
The Stephill SSDP50 is powered by a professional 1500rpm Perkins water-cooled diesel engine.
Low-speed 1500rpm operation is particularly suited to standby and continuous-duty generator applications, helping provide:
- Smooth and dependable operation
- Reduced engine wear
- Lower operating noise
- Improved fuel efficiency
- Long-term durability
The engine protection system includes automatic shutdown for high engine temperature and low oil pressure.
Deep Sea DSE6110 Controller
The integrated Deep Sea DSE6110 controller provides simple push-button starting and stopping.
A two-wire remote-start facility is also included, allowing the generator to be activated by compatible external equipment or a suitably configured Automatic Transfer Switch.
The lockable control-panel door helps prevent unauthorised access and protects the controls when the generator is unattended.
Mecc Alte AVR Alternator
The SSDP50 is fitted with a maintenance-free brushed Mecc Alte alternator incorporating Automatic Voltage Regulation.
The AVR system maintains the output voltage to approximately ±1%, helping deliver a stable electrical supply for connected tools, machinery and equipment.
The alternator also benefits from Mecc Alte Total Winding Protection and is covered by a limited three-year manufacturer’s warranty, subject to the applicable terms and conditions.
Three-Phase and Single-Phase Outputs
The generator is equipped with a versatile selection of 400V three-phase and 230V single-phase industrial sockets:
- 1 × 400V 32A
- 1 × 400V 63A
- 1 × 230V 16A
- 2 × 230V 32A
Each socket is individually protected against overload. A hard-wire connection facility is also provided for suitable fixed installations.
An Earth Leakage Circuit Breaker is fitted to the 400V/230V output for additional electrical protection.
All electrical installation and connection work must be completed by a suitably qualified electrician.
Long-Running 350-Litre Fuel Tank
The integrated 350-litre diesel tank provides up to approximately 42 hours of operation, depending on the connected load and operating conditions.
This substantial fuel capacity makes the SSDP50 particularly suitable for extended standby use, remote locations and applications where frequent refuelling would be inconvenient.
External Fuel-Tank Connection
A three-way fuel valve allows the generator to be connected to an external bowser or bulk fuel tank.
An additional fuel-transfer pump may be required depending on the location, height and configuration of the external fuel supply.

The Stephill SSDP50 is ideal for:
- Industrial premises
- Commercial buildings
- Agricultural operations
- Workshops and factories
- Construction and infrastructure projects
- Emergency backup power
- Temporary site power
- Equipment-hire fleets
- Fixed standby installations
- Remote-start applications
