The Lombardini Marine LMG 14000 is a high-capacity supersilenced marine diesel generator for 50Hz onboard AC power systems. It produces 12 kW continuous output, or 15 kVA, at 3,000 RPM and uses a Lombardini LDW 1404 MG four-cylinder FOCS diesel engine with a water-cooled brushless synchronous alternator. The insulated fiberglass sound enclosure is designed for a suitable yacht, workboat, or larger recreational-vessel generator installation.

The standard 50Hz configuration provides 400/230V three-phase AC output. Verify the exact model specification before ordering because output voltage, phase, and available configurations can vary by market. A full installation requires marine diesel fuel plumbing, raw-water cooling, wet exhaust, ventilation, starting battery, AC distribution, shore-power isolation, grounding, circuit protection, and adequate service access.

Key Specifications

- High-capacity supersilenced marine diesel generator for 50Hz AC electrical systems.

System Integration

This generator requires a complete marine-generator installation, including diesel fuel supply and return, seawater intake and strainer, anti-siphon arrangement where needed, exhaust system, ventilation, starting battery, AC distribution, shore-power transfer or interlock, grounding and bonding, circuit breakers, and correctly sized cables.

Confirm that the onboard electrical system requires 50Hz three-phase output and assess phase balancing, power factor, continuous load, motor-starting current, and simultaneous demand. If a single-phase output configuration is required, verify factory availability and the exact generator order code before purchase.

Installation Considerations

Mount the generator on a rigid vibration-isolated base designed for approximately 245 kg. Allow service clearance for fuel filters, oil changes, coolant, raw-water pump, alternator, electrical terminals, exhaust connection, and canopy removal. Maintain reliable raw-water supply, correct exhaust routing, ventilation, fuel-system integrity, and electrical isolation from shore power. Test output voltage, frequency, phase sequence, cooling, shutdowns, and load response during commissioning.

Before Ordering

Confirm required continuous and surge electrical load, exact 400/230V three-phase 50Hz or other approved output configuration, available 860 mm by 580 mm by 650 mm installation space, structural support for approximately 245 kg, phase-balancing requirements, diesel fuel layout, seawater intake, exhaust route, ventilation, starting-battery circuit, AC distribution, transfer-switch design, grounding plan, service access, and qualified marine-generator installation requirements before purchase.
