The Lombardini Marine LMG 18000 is a high-output supersilenced diesel generator for vessels requiring substantial onboard AC power. In its 50Hz configuration, it provides 16 kW continuous output, or 20 kVA, at 3,000 RPM. The generator uses a Lombardini LDW 2204 four-cylinder FOCS marine diesel engine, a water-cooled brushless alternator, and a sound-insulated fiberglass canopy for suitable yacht, commercial, or high-demand vessel installations.

The standard 50Hz generator configuration provides 400/230V three-phase AC output. A single-phase version may be available for selected markets or model configurations, but voltage, phase, frequency, and output must be verified against the exact order code. The generator requires a complete fuel, cooling, exhaust, ventilation, starting, AC distribution, isolation, grounding, and service-access installation plan.

Key Specifications

- High-output supersilenced marine diesel generator for 50Hz onboard AC systems.
- Provides 16 kW continuous output, equivalent to 20 kVA, at 3,000 RPM.
- Uses a Lombardini LDW 2204 four-cylinder FOCS diesel engine with 2,199 cc displacement.
- The standard documented 50Hz output is 400/230V three-phase AC; verify any single-phase option against the exact generator configuration.
- Uses a water-cooled brushless synchronous alternator.
- Employs freshwater cooling through a heat exchanger with seawater circulation and integrated lube-oil cooling.
- Includes remote electronic controls with operating information and protective shutdown functions.
- Measures approximately 1,070 mm by 580 mm by 650 mm and has a listed dry weight of approximately 310 kg.

System Integration

This generator requires a professionally designed marine installation, including diesel fuel feed and return, raw-water intake and strainer, exhaust and waterlock system, engine-room ventilation, starting battery, three-phase or single-phase AC distribution, transfer switch or shore-power interlock, grounding and bonding, circuit protection, and appropriately rated cables.

Assess continuous demand, simultaneous loads, power factor, phase balancing for three-phase installations, motor-starting surge, and future expansion before selecting a 20 kVA generator. Confirm whether the vessel electrical system uses 230V single-phase or 400/230V three-phase power, as incorrect phase or frequency selection can damage onboard equipment.

Installation Considerations

Install the generator on a rigid vibration-isolated foundation designed for approximately 310 kg, with access for engine oil, fuel filters, coolant, belts, impeller, electrical terminals, exhaust service, and canopy removal. Provide reliable cooling-water supply, correct fuel plumbing, safe exhaust routing, ventilation, and electrical isolation from shore power. Test voltage, frequency, phase sequence, cooling, alarms, shutdowns, and load response during commissioning.

Before Ordering

Confirm continuous and surge load requirements, exact 50Hz voltage and phase configuration, available 1,070 mm by 580 mm by 650 mm installation space, structural support for approximately 310 kg, diesel fuel layout, raw-water intake, exhaust route, ventilation, starting-battery connection, remote-control cable route, three-phase distribution and phase balancing where applicable, transfer-switch design, grounding plan, service access, and qualified marine-generator installation requirements before purchase.
