The Pramac P11000 is a robust 11 kVA single phase silent diesel generator delivering 10 kW standby and 9 kW prime power. A Stage V Yanmar engine, 230/115V output, 7x CEE sockets and a weatherproof acoustic canopy make it a versatile choice for professional site, workshop and backup duties.
The P11000 provides a standby (ESP) rating of 11 kVA / 10 kW for temporary emergency power and a prime (PRP) rating of 10 kVA / 9 kW for applications requiring longer operating periods. This makes it a capable 10 kW diesel generator for backup duties and a dependable 9 kW diesel generator when supplying an appropriate ongoing load.
Its single phase output is particularly well suited to standard site equipment, power tools, pumps, lighting, workshop machinery and other 230V or 115V loads. Unlike a three-phase generator, the available output does not need to be balanced across three separate phases, which can simplify power distribution for predominantly single phase equipment.
The generator operates at 50Hz with a 0.9 power factor. When sizing the P11000, allow sufficient capacity for electric motors, compressors and pumps that draw additional current while starting. The combined demand across all connected sockets must remain within the generator’s total rating as well as the individual socket and circuit-breaker limits.
At the heart of the Pramac P11000 is a Yanmar 3TNM74F-NHPGE diesel engine. This naturally aspirated, water-cooled engine has a displacement of 993cm³ and runs at 3000rpm. Mechanical speed governing provides a straightforward, proven system for maintaining engine speed under changing loads.
The engine meets Stage V exhaust-emissions requirements at 50Hz, making this modern Stage V diesel generator a strong choice for organisations seeking efficient professional equipment with reduced regulated emissions. Electric starting is supported by a 12V, 45Ah battery, while the engine holds 3.4 litres of oil and 1 litre of coolant.
Yanmar engines are widely used in professional power equipment, giving the P11000 single phase a dependable foundation for construction, maintenance, agricultural and commercial applications.
A 24-litre integrated diesel tank supports productive working periods without frequent refuelling. According to the manufacturer’s data, fuel consumption is approximately 2.85 litres per hour at 75% of continuous load, providing up to 8.42 hours of running time. At 100% continuous load, consumption is approximately 4.04 litres per hour, with a stated runtime of 5.94 hours.
Actual fuel use will vary with electrical demand, operating conditions and maintenance. Avoiding prolonged operation at very low loads can also help a diesel engine reach an effective working temperature and reduce the risk of carbon accumulation.
An external filling point makes refuelling more convenient, while the integrated fuel-level sensor and low-fuel warning lamp help the operator monitor the available supply.
This is the P11000 single phase with sockets and an MCP manual control panel. A voltage selector switch allows the operator to choose the required 230V or 115V configuration, supporting both general single phase equipment and lower-voltage site tools.
The IP44 CEE socket arrangement comprises:
This generous outlet selection makes the P11000 230/115V especially practical where several appropriately rated tools or distribution leads need to be connected. The 115V provision is valuable on UK construction sites, while the 230V outlets can serve compatible workshop, commercial and maintenance equipment.
The voltage must be selected correctly before connecting loads. Operators should also confirm equipment voltage, starting current, plug type and total demand rather than assuming every socket can deliver its maximum current simultaneously.
The P11000 uses a galvanised sheet-metal enclosure with acoustic insulation and an integrated residential-grade silencer. It produces a stated sound pressure level of 68 dB(A) at 7m and 81 dB(A) at 1m, with a guaranteed sound power level of 96 dB(A).
These figures make it a compelling silent diesel generator for workplaces where noise control matters, including residential areas, commercial premises and jobs undertaken outside normal working hours. Site layout, nearby buildings, reflective surfaces and load level can all affect the noise experienced in practice.
The enclosure is designed to resist normal weather exposure, but the generator still requires appropriate siting, ventilation and exhaust clearance. Like every diesel generator, it must never be operated inside an unventilated building or any occupied space where exhaust gases could accumulate.
The MCP is deliberately simple and easy to understand. Its key-operated selector provides OFF, ON and START positions, while an analogue hour counter records operating time for maintenance planning.
Standard control-panel equipment includes:
This key start diesel generator is intended for attended, manual operation. It is not supplied in this configuration as an automatic mains-failure generator, so it will not automatically start and transfer a building’s load when utility power fails. Any connection to fixed wiring must be designed and installed by a suitably qualified electrician using correctly rated switching and protection.
A Mecc Alte two-pole alternator converts the engine’s mechanical power into 50Hz electrical output. It features Class H insulation, IP23 protection and capacitor-based voltage regulation with a listed voltage tolerance of 5%.
This proven arrangement is suited to many common tools, lighting systems, pumps and general electrical loads. Buyers planning to supply unusually sensitive electronics, specialist control equipment or loads with demanding starting characteristics should confirm their precise power-quality requirements before ordering.
Despite offering substantially more capability than a small portable generator, the P11000 1 phase remains manageable for professional transport and placement. Its dimensions are 1400mm long, 650mm wide and 975mm high, with a dry weight of 328kg.
The base frame accommodates forklift handling, while a single lifting point assists with safe crane placement when appropriate lifting equipment is used. Properly sized anti-vibration mounts isolate the engine-alternator assembly from the supporting frame.
A hinged canopy provides broad access to internal components, helping engineers reach routine service points. An optional wheel kit is available where the generator needs to be repositioned around a suitable level site.
The combination of single phase power, selectable voltage and multiple sockets makes this 11 kVA diesel generator particularly useful for:
For standby applications, the published warranty is two years or 1000 operating hours. For prime applications, it is one year or 3000 hours, subject to the manufacturer’s current warranty terms, servicing requirements and operating conditions.
For buyers who need a compact, canopied single phase diesel generator with a respected Yanmar engine, practical socket provision and straightforward manual controls, the Pramac P11000 offers a well-balanced professional power solution.
