• Four-stroke diesel operation
• Approximately 1.1-litre displacement
• Mechanical fuel regulation
• Indirect fuel injection
• Naturally aspirated air intake
• 1500 RPM operating speed

The engine’s Super Glow system supports easier starting in lower temperatures, while its mechanical fuel system provides practical serviceability for vessels operating away from major service centres. (Nanni Diesel)

A correctly sized diesel marine generator allows vessel owners to operate essential onboard equipment without depending on marina electricity or running the propulsion engine solely for battery charging.

The QLS10T can provide:

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

Continuous and Prime Power Ratings

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

The Nanni QLS10T provides:

These ratings are published in Nanni’s generator product guide. The continuous rating is the more relevant figure when evaluating the vessel’s normal sustained electrical load, while the prime rating provides the published operating capacity under Nanni’s specified duty conditions. (Nanni Industries)

A vessel’s normal working load should remain within the generator’s approved operating capacity while leaving reasonable reserve for temporary increases in demand.

Equipment such as pumps, refrigeration compressors, electric motors, and battery chargers may require more power during startup than during normal operation. These temporary loads should be included when calculating whether the QLS10T is suitable for the vessel.

An undersized generator may experience:

• Electrical overload
• Voltage instability
• Excessive operating temperature
• Difficulty starting motor-driven equipment
• Frequent protective shutdowns
• Reduced generator life

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

Stable 400V Three-Phase Electrical Output

The QLS10T is designed for vessels requiring dependable 400V three-phase marine power. Three-phase systems are commonly used for compatible pumps, motors, ventilation equipment, refrigeration machinery, and other onboard systems requiring balanced electrical distribution.

The generator may support compatible equipment such as:

• Seawater and freshwater pumps
• Refrigeration systems
• Ventilation equipment
• Battery chargers
• Navigation electronics
• Communication systems
• Lighting circuits
• Small hydraulic systems
• Professional vessel equipment

Before installation, a qualified marine electrician should verify:

• Generator voltage
• Frequency
• Phase rotation
• Earthing and bonding
• Cable sizes
• Circuit protection
• Switchboard compatibility
• Load distribution

Single-phase equipment may be supplied through a properly engineered three-phase distribution system. However, the loads should be balanced across the phases because excessive imbalance can reduce available output and affect electrical stability.

Stable Electricity for Sensitive Vessel Systems

Modern yachts and commercial boats rely on dependable electricity for navigation, communications, refrigeration, safety systems, battery charging, monitoring, and daily operations.

The QLS generator range was developed to supply reliable power for marine equipment, including loads that may be sensitive to voltage variation. Nanni describes the series as using compact, mechanically robust generator technology designed for dependable marine service. (Nanni Diesel)

A stable vessel power-generation system can support:

• Navigation equipment
• Communication systems
• Battery chargers
• Refrigeration controls
• Vessel-monitoring equipment
• Lighting
• Pumps and motor starters
• Safety and alarm systems

Electrical performance depends on the complete installation. Generator speed, voltage regulation, cable sizing, grounding, switchboard design, load balance, and circuit protection all influence power quality.

Professional installation and commissioning are therefore important for dependable long-term performance.

Marine Cooling for Dependable Operation

Reliable cooling is essential for marine generator performance. Onboard generator sets normally operate inside enclosed machinery spaces where heat must be removed efficiently.

Nanni uses marine cooling arrangements based on heat exchange between the engine coolant and seawater. Related QLS models use a seawater pump with a rubber impeller, while keel-cooling configurations may also be suitable for certain installations. (Nanni Diesel)

A properly maintained marine generator cooling system supports:

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

Routine inspection should include:

• Coolant condition
• Raw-water strainers
• Seawater flow
• Hoses and clamps
• Drive belts
• Raw-water pump impeller
• Heat-exchanger surfaces
• Wet-exhaust components

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

Where the generator is installed below the vessel’s waterline, the seawater and exhaust system should also be assessed for siphoning risk.

Compact Installation Dimensions

The Nanni QLS10T is one of the more compact models in Nanni’s mechanical QLS range.

Nanni publishes the following approximate dimensions:

These dimensions make the generator suitable for vessels where machinery-space dimensions are limited but reliable three-phase electricity is still required. (Nanni Industries)

Before installation, the vessel’s engineering team should confirm:

• Generator footprint
• Mounting-point positions
• Dry and operating weight
• Maintenance clearances
• Ventilation requirements
• Seawater inlet location
• Exhaust routing
• Fuel supply and return connections
• Main cable access
• Lifting and removal space

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

Low-Speed Operation and Onboard Comfort

Noise and vibration are important considerations aboard yachts, passenger boats, and liveaboard vessels.

The QLS10T operates at 1500 RPM, helping reduce mechanical wear and vibration compared with many 3000 RPM generator systems. Its naturally aspirated three-cylinder engine also provides a straightforward operating configuration suitable for smaller vessel installations. (Nanni Industries)

A correctly installed quiet marine generator should include:

• Flexible anti-vibration mounts
• Adequate machinery-space ventilation
• Properly supported hoses and cables
• A correctly designed wet-exhaust system
• Suitable compartment insulation
• Sufficient service clearance

Final onboard noise depends not only on the generator but also on mounting quality, compartment construction, exhaust design, ventilation openings, and vibration transfer through the vessel structure.
