1100kVA Diesel Generator – Baudouin Engine – Three Phase

The Solent Power SPP1100BSC is a 1100kVA standby / 1000kVA prime rated three phase diesel generator, purpose-built for critical power applications that demand absolute reliability. Driven by the Baudouin 8M33G1100/5 engine and paired with a Stamford S6L1D-E4 alternator, this canopied generating set delivers heavyweight performance across industrial, infrastructure, and commercial environments throughout the UK and beyond.

1100kVA 3 Phase Baudouin Engine Performance

The Baudouin 8M33G1100/5 is an eight-cylinder, V-configuration diesel engine displacing 26.14 litres, running at 1,500 rpm on a 50 Hz cycle. Turbocharged and aftercooled, it produces 890 kWm at prime rating and 975 kWm at standby, with direct injection combustion and a fully electronic governor ensuring tight load response across the full operating range. This level of engineering is why Baudouin engines are consistently chosen for mission-critical applications where load transient behaviour and sustained output stability cannot be compromised.

At prime power rating — applicable for continuous operation at variable load with no restriction on annual hours — the SPP1100BSC delivers 1000 kVA / 800 kWe, with a permitted 10% overload for one hour in every twelve. Standby output is rated at 1100 kVA / 880 kWe, in full compliance with ISO8528-1 and ISO3046-1 under standard reference conditions of 25°C, 100 m ASL and 30% relative humidity. Fuel consumption at 100% prime power load is 214 litres per hour, rising to 235.5 L/hr at 110% prime load — figures that enable accurate operational cost planning from day one.

The engine’s 24V DC electrical system is supported by a maintenance-free battery, integrated battery charger, connecting cables, engine water heater, and battery isolator switch — all included as standard. The engine oil system holds 110 litres total capacity, with a wet sump, spin-on oil filter, filler, and dipstick providing straightforward servicing access. Bore and stroke are 150 × 150 mm, and the engine features Ecoplus fuel filtration alongside an electronically governed, rotary-type fuel pump for precise fuel management throughout the load cycle.

Alternator & Electrical Output

The Stamford S6L1D-E4 alternator is a single-bearing, flexible disc-coupled machine wound for three-phase, 4-pole operation at 0.8 power factor. Rated current at 400V / 100% load is 1,588 A, and voltage regulation is held within ±1% by the integrated AVR — a standard critical for load-sensitive equipment such as data centre UPS systems, variable speed drives, and medical infrastructure. Insulation is Class H, providing thermal headroom well above the operating envelope of most heavy-duty diesel generator applications.

The alternator carries an IP23 ingress protection rating, appropriate for most indoor plant room and covered outdoor installations. Excitation is via shunt topology, and the unit is rated for operation up to 1,000 m altitude with an overspeed rating of 2,250 min⁻¹. These parameters confirm the SPP1100BSC as a technically sound choice wherever a reliable, precisely regulated three phase generator for sale is required in the UK, whether for permanent standby duty or continuous prime power.

Enclosure, Build & Noise Levels

The SPP1100BSC is supplied in a fully sound-attenuated canopy enclosure measuring 5,000 × 2,270 × 2,550 mm (L × W × H) and weighing 9,250 kg dry. Noise output is rated at 88 dB(A) at 7 metres at 100% load — achieved through thermo-acoustic internal lining capable of withstanding fire, high temperature, and severe environmental conditions. The residential-grade exhaust muffler is manufactured from galvanised steel and is internally mounted, protecting it from external impact and corrosion over the service life of the set.

The canopy construction is extremely rugged and highly corrosion-resistant, finished in high-quality polyester powder paint. Side doors open through 180° for unobstructed access during servicing, and a control panel viewing window with lockable door allows monitoring without opening the enclosure. Lube oil and radiator drain points are accessible without disturbing the installation, and the modular design philosophy means individual components can be replaced on-site without specialist fabrication. This silent generator configuration is particularly well suited to residential-adjacent sites, healthcare facilities, and urban construction compounds where noise management is a planning requirement.

Lifting is catered for via top-access crane lifting points and forklift pockets, providing full flexibility for deployment with either a crane or a telehandler. Earth leakage protection, a fully guarded cooling fan, and an externally mounted emergency stop push button are all standard safety provisions. The thermostat operates up to 40°C ambient, and the cooling air management system is engineered to prevent elevated water temperatures under sustained full-load operation in warm climates or enclosed plant rooms.

Control System & Starting

The SPP1100BSC is supplied as standard with the Deep Sea Electronics DSE6120 controller, a proven and widely supported automatic generator controller used across the UK generating set industry. The DSE6120 provides full instrumentation including phase voltage (3-phase display), current, frequency, active power, reactive power, apparent power, power factor, and electric energy metering. Engine monitoring covers oil pressure, water temperature, speed, battery voltage, and elapsed hours, with fuel meter and sensor capability also included.

Protection functions are comprehensive at this level. Generator protection includes abnormal voltage detection, overcurrent warning and protection, over-frequency protection, and MCCB-based short circuit protection. Engine protection covers low oil pressure warning and shutdown, high temperature warning and shutdown, overspeed warning and protection, and alternator charger monitoring. The DSE6120 supports remote start, AMF (Auto Mains Failure) function, programmable inputs and outputs, USB communication, CAN bus interface, service indication, and fault history logging — making it straightforward to integrate into building management systems or remote monitoring platforms.

For applications requiring more advanced capability, the DSE7310/20 is available as an optional upgrade, adding RS232/484 communication ports, extended module capability, and optional gen-gen synchronising. The DSE8610/20 option extends this further to include full gen-mains synchronising and RS232/485 communications. Starting is via 24V DC electric start with a dedicated starter motor and charge alternator, with the included battery charger maintaining battery readiness during extended standby periods.

Applications & Industries

At 1100 kVA standby output, the SPP1100BSC occupies a segment of the diesel generator market reserved for large-scale critical power requirements. Typical applications include data centres and server farms requiring guaranteed uptime, large NHS hospital and healthcare campus standby power, industrial manufacturing facilities with high-current three phase machinery, water and wastewater treatment infrastructure, large hotels and conference venues, and ports or logistics hubs where continuous operations cannot tolerate mains interruption.

The canopied format makes this set equally suitable for permanent outdoor installation in a secure plant compound or for temporary power on major construction projects, film productions, or events requiring substantial three phase generation capacity. When paired with the optional Automatic Transfer Switch (available from 32–4,000A in 4-pole configuration), the set can be configured for fully automatic AMF operation, transferring load from mains to generator supply within seconds of a mains failure — without any operator intervention. This integrated approach to 24-hour power protection is a core part of the solution Solent Power offers to clients specifying generating sets in this power class.
