FAQ
Find answers to frequently asked questions about generator sets, power solutions, customization requirements, and project configurations.
  • How do I choose the right generator size for my project?

    2026-10-14

    Generator sizing should be based on the total connected load, starting current of large motors, load characteristics, operating sequence, required redundancy, and expected future expansion. For projects involving motors, elevators, pumps, compressors, UPS systems, or other high-inrush loads, simply adding up the equipment kW is not sufficient. Provide us with your load list and operating conditions, and we can assist with generator sizing.【detailed】

  • What information should I provide to get an accurate generator quotation?

    2026-10-14

    Please provide the required standby or prime power, voltage, frequency, phase, application, installation location, ambient temperature, altitude, enclosure type, ATS requirement, synchronization requirement, and any preferred engine or alternator brand. For project tenders, you may also send us the technical specification or BOQ for review.【detailed】

  • What is the difference between standby power and prime power?

    2026-10-14

    Standby power is intended for emergency use when the normal utility supply fails, while prime power is designed for applications where the generator operates as a primary power source for extended periods under varying loads. The correct rating should be selected according to the actual operating profile and the applicable engine/generator rating standard.【detailed】

  • Which diesel engine brands are available for your generator sets?

    2026-10-14

    We offer diesel generator sets powered by a wide range of well-established engine brands, including Dongfeng Cummins (DCEC), Chongqing Cummins (CCEC), Yuchai, SDEC (Shanghai Diesel Engine), and Perkins, among other options.
    Different engine brands and models are available to meet various requirements for power output, application, project budget, operating environment, and local service support. Whether you need generator sets for industrial facilities, construction projects, commercial buildings, hospitals, data centers, or standby and prime power applications, we can recommend a suitable engine configuration based on your project specifications.
    If your project requires a specific engine brand or model, please provide the required power rating, voltage, frequency (50Hz/60Hz), application, and destination country, and our team will confirm the available configuration.【detailed】

  • Which alternator brands can you supply for your diesel generator sets?

    2026-10-14

    We offer a range of alternator options from established brands, including Stamford (Hong Kong), Stamford (Wuxi), Leroy-Somer, and Faraday, among other options.
    Different alternator brands and models can be matched according to the generator set power rating, voltage, frequency, application, project specifications, and budget. We can provide configurations for 50Hz and 60Hz applications, as well as different voltage requirements for international markets.
    For projects with specific technical requirements, please provide the required power rating, voltage, frequency, phase, application, destination country, and preferred alternator brand. Our team will recommend a suitable engine-and-alternator combination and confirm the available model.
    If a particular alternator brand or model is specified in your tender documents or project specifications, please send us the relevant requirements for confirmation.【detailed】
