It can also reduce the need to operate the vessel\u2019s propulsion engines solely for battery charging or auxiliary electrical production. Continuous and Prime Power Ratings Understanding generator ratings is important when selecting an auxiliary marine power system. The Nanni QLS 65T provides: Electrical Specification Rating Continuous Power 37.5 kW \/ 45.8 kVA Prime Power 53.7 kW \/ 65.4 kVA Voltage 400V Frequency 50 Hz Electrical Configuration Three Phase Power Factor 0.8 Operating Speed 1500 RPM Nanni identifies the QLS 65T as a 53.7 kW prime-power generator operating at 400V, three phase, and 50 Hz. (Nanni Industries) The continuous rating should be considered when evaluating sustained electrical demand, while the applicable prime rating should be reviewed according to the vessel\u2019s operating profile and Nanni\u2019s approved duty conditions. The vessel\u2019s expected electrical load should leave reasonable reserve capacity for temporary demand increases and motor-starting requirements. Equipment such as pumps, compressors, refrigeration systems, hydraulic machinery, ventilation motors, and water makers may require substantially more electricity during startup than during normal operation. Selecting a generator that is too small may result in: Electrical overload Voltage instability Excessive operating temperatures Difficulty starting large electric motors Frequent protective shutdowns Reduced generator service life However, selecting a generator that is significantly larger than required may result in prolonged operation under very light loads. A professional marine electrical load assessment helps balance electrical capacity, startup demand, operating reserve, efficiency, and long-term generator performance. Stable 400V Three-Phase Electrical Output The QLS 65T is designed for vessels requiring dependable 400V three-phase marine power. Three-phase electrical systems are commonly used aboard larger yachts and commercial vessels because they distribute power efficiently to compatible motors, pumps, compressors, and auxiliary machinery. The generator may support compatible equipment such as: Marine air-conditioning systems Seawater and freshwater pumps Refrigeration and cold-storage equipment Ventilation and extraction machinery Hydraulic power units Water-making systems Battery-charging equipment Commercial galley machinery Workshop tools Auxiliary electric motors Navigation and communication systems Professional marine equipment The QLS range uses Leroy-Somer marine alternators, which are recognized for dependable construction and versatile power-generation applications.
