More Than Manufacturing
For project customers, selecting a generator is only one part of the job.
Correct load calculation, voltage selection, synchronization logic, ventilation, noise reduction, control strategy, protection settings and integration with the customer's electrical system can determine whether the complete power system performs as expected.
Our engineering team therefore supports customers from the early stage of a project.
Based on load characteristics, site conditions and operating requirements, we can assist with generator sizing, configuration design, parallel operation, low-voltage and high-voltage solutions, ATS and automatic control, remote monitoring, generator-room noise reduction and integration with energy-storage systems.
OEM/ODM and project-specific customization are also available for distributors, contractors and project buyers.

  • Proven Project Experience

    2026-10-13

    Over the years, Sanzhong Energy has served more than 1,000 customers and accumulated experience across industrial, institutional and infrastructure projects.
    Our project record includes multiple large-capacity generator installations, such as 3 × 900 kW generator sets with supporting noise-control works for an educational campus, 4 × 1,000 kW units for another campus development, a 640 kW generator project for Mitsubishi Heavy Industries Dongfang Gas Turbine (Guangzhou), and 2 × 1,000 kW, 10.5 kV high-voltage containerized generator sets for supporting infrastructure associated with the Jiangmen Underground Neutrino Observatory project.
    These projects have strengthened our capabilities not only in equipment manufacturing, but also in system configuration, project coordination, installation support and commissioning.【detailed】

  • Manufacturing & Quality Control

    2026-10-13

    Sanzhong Energy operates from a 5,000 m² facility in Guangdong with manufacturing, assembly, testing, warehousing and project-support capabilities.
    Quality control starts with component selection. Key components are sourced through established supply channels, with branded engines, brushless alternators and intelligent controllers selected according to project requirements.
    Generator sets are manufactured with reference to applicable GB/T 2820 and ISO 8528 requirements. Before shipment, units undergo inspection and testing procedures that can include load running, load-impact testing, control and protection-function verification, and overall operating checks.
    Our generator systems can also be engineered for challenging operating environments involving high temperatures, humidity, dust and demanding continuous-load conditions.
    The company maintains ISO 9001 Quality Management, ISO 14001 Environmental Management and ISO 45001 Occupational Health & Safety Management certifications.【detailed】

Different markets require different solutions.
OEM, ODM & Customized Solutions
For distributors, contractors, EPC companies and project owners, we can provide customized configurations based on required power output, voltage and frequency, enclosure design, noise requirements, control systems, synchronization, monitoring and specific site conditions.
Our goal is not to force every customer into a standard configuration. It is to understand how the equipment will actually be used and develop a solution around those requirements.
