It offers a practical onboard power solution for vessels that require efficient three-phase electricity without moving to a substantially larger generator set.

Selecting the correct marine generator requires more than comparing model names or maximum output. Continuous demand, motor-starting loads, phase balance, machinery-space dimensions, cooling-water supply, ventilation, exhaust routing, expected operating hours, and future electrical upgrades should all be reviewed before purchase.

Purpose-Built Nanni QMS Marine Engineering

The Nanni QMS generator range is developed specifically for marine power generation. Unlike a portable or general-purpose industrial generator adapted for use aboard a vessel, the QMS13T is supplied as an integrated marine diesel generator set with dedicated cooling, exhaust, electrical, mounting, and installation features.

The QMS13T uses a four-cylinder, inline, four-stroke Kubota diesel engine with approximately 1.5 litres of displacement. Its engine configuration includes mechanical fuel regulation, indirect fuel injection, naturally aspirated air intake, and 1500 RPM operation for stable 50 Hz electricity. (Nanni Industries)

Nanni equips the QMS range with Mecc Alte alternators, which are designed as compact synchronous units for dependable electrical production. Most generators in the QMS family are also available with an optional sound enclosure manufactured from insulated painted marine-aluminium panels. (Nanni Industries)

The generator is engineered for environments affected by:

• Continuous vibration
• High humidity
• Saltwater exposure
• Restricted machinery-space ventilation
• Changing electrical loads
• Vessel movement and inclination
• Extended operation away from shore power

Customers evaluating the New Nanni QMS13T price should consider more than the initial purchase cost. Electrical capacity, fuel efficiency, service access, marine cooling, low-speed operation, installation compatibility, and long-term parts support all contribute to the generator’s overall value.

Proven Four-Cylinder Kubota Diesel Performance

The QMS13T uses a proven Kubota diesel platform designed for dependable electrical generation. Kubota engines are widely used in marine and power-generation applications because of their durable construction, practical maintenance, and established operating history.

The engine configuration includes:

• Four cylinders in line
• Four-stroke diesel operation
• Approximately 1.5-litre displacement
• Mechanical fuel regulation
• Indirect fuel injection
• Naturally aspirated air intake
• 1500 RPM rated speed

The mechanical fuel system provides a straightforward arrangement that may appeal to yacht owners and professional operators who value familiar diesel-maintenance procedures and reduced dependence on complex electronic fuel controls.

A correctly sized diesel marine generator allows vessel owners to operate essential electrical systems while cruising, remaining at anchor, or working offshore without relying on marina electricity. It can also reduce the need to operate the vessel’s propulsion engine solely for battery charging or auxiliary electrical production.

The QMS13T is designed to provide:

• Reliable electricity for essential vessel systems
• Stable operation under changing electrical demand
• Efficient low-speed diesel performance
• Practical routine maintenance
• Reduced mechanical wear
• Dependable auxiliary power during extended voyages

Continuous and Prime Power Ratings

Understanding generator ratings is essential when selecting an auxiliary marine power system.

Nanni lists the QMS13T as a 10.2 kW prime-power generator with 230/400V three-phase output at 50 Hz. Its continuous rating is approximately 9.1 kW. (Nanni Industries)

The continuous rating is generally the more relevant figure when evaluating sustained onboard demand. Reasonable reserve capacity should remain available for temporary load increases and equipment startup requirements.

Pumps, refrigeration compressors, ventilation motors, battery chargers, and water makers may draw considerably more electricity during startup than during normal operation. An undersized generator may experience overload, voltage instability, difficulty starting motors, excessive heat, and repeated protective shutdowns.

However, selecting a generator that is substantially larger than required may result in prolonged operation under very light load. A professional marine electrical load assessment helps balance capacity, efficiency, startup demand, and operating reserve.

Stable Three-Phase Electrical Output

The QMS13T is designed for vessels requiring dependable 230/400V three-phase marine power. Three-phase systems distribute electricity efficiently to compatible motors, pumps, refrigeration equipment, ventilation systems, and auxiliary machinery.

The generator may support compatible equipment such as:

• Seawater and freshwater pumps
• Refrigeration and freezer systems
• Battery-charging equipment
• Ventilation and extraction systems
• Navigation electronics
• Communication equipment
• Vessel-monitoring systems
• Lighting circuits
• Water-making equipment
• Auxiliary electric motors
• Professional marine equipment

Before installation, a qualified marine electrician should verify voltage, frequency, phase rotation, earthing, cable sizes, circuit protection, switchboard compatibility, and load distribution.

Single-phase equipment may be supplied through a properly designed three-phase distribution system. However, loads should be balanced across all phases because excessive imbalance may reduce usable generator capacity and affect electrical stability.

Marine Cooling for Dependable Operation

Reliable cooling is essential for dependable marine generator performance. Onboard generators are normally installed within enclosed machinery spaces where engine and alternator heat must be managed effectively.

Nanni’s generator range uses its Compact Cooling approach, developed to support reliable operation and long service life in marine environments. The QMS range generally uses heat exchange between the internal coolant circuit and seawater, with an impeller-type raw-water pump supplying the external cooling circuit. (Nanni Diesel)

A properly maintained marine generator cooling system supports:

• Stable engine operating temperature
• Efficient heat transfer
• Reliable output under sustained loads
• Reduced thermal stress
• Protection of internal components
• Longer generator service life

Routine maintenance should include inspecting coolant condition, raw-water strainers, seawater flow, hoses, clamps, belts, impellers, heat-exchanger surfaces, and wet-exhaust components.

Restricted seawater flow, a worn impeller, blocked cooling passages, or inadequate machinery-space ventilation may cause overheating even when the generator is correctly sized.

Low-Speed Operation and Reduced Vibration

Every 50 Hz generator in Nanni’s QMS range operates at 1500 RPM. This low-speed design helps reduce friction, mechanical wear, noise, and vibration compared with many compact 3000 RPM generator systems. (Nanni Diesel)

Lower operating speed may contribute to:

• Smoother generator performance
• Reduced vibration transmission
• Lower mechanical wear
• Improved onboard comfort
• Dependable extended operation
• Longer equipment life with correct maintenance

A properly installed quiet marine generator should also include flexible mounts, effective machinery-space ventilation, supported hoses and cables, and a correctly engineered wet-exhaust system.

Actual onboard noise depends on the entire installation. Hull construction, mounting quality, exhaust routing, compartment insulation, and ventilation openings all influence acoustic performance.

Optional Soundshield and Compact Installation

The QMS13T is available with an optional sound enclosure designed to reduce airborne engine and alternator noise. Nanni states that sound-enclosed QMS generator sets can achieve sound levels around 54 dB at seven metres under specified conditions. (Nanni Diesel)

Published dimensions for the QMS13T are approximately:

These figures should be treated as reference values. Final installation planning should use the approved model-specific drawing supplied with the generator. (Nanni Industries)

Before installation, confirm machinery-space dimensions, mounting points, service access, ventilation capacity, seawater connections, exhaust routing, fuel-line access, cable entry, and lifting clearance.

When replacing an existing boat generator, matching only the electrical output is not sufficient. Voltage, frequency, phase configuration, dimensions, cooling capacity, exhaust routing, mounting arrangements, and switchboard compatibility must also be reviewed.
