Diesel Generator Selection Guide
 

Power Output

Specify required kVA or kW based on your total connected load, motor starting surges, and future expansion buffer.

 

Yuchai Generator Set
Weichai Generator Set

Operation Mode

Determine if the unit will operate as Prime Power (continuous running for off-grid sites) or Standby Power (emergency backup for critical facilities).

Electrical Parameters

Select standard voltages (110V to 480V), frequencies (50Hz or 60Hz), and phases (single or three-phase).

FAQ

 

Q: How do I choose between an open-type and silent-type generator?

A: Open-type generators are commonly installed in dedicated generator rooms with suitable ventilation and acoustic treatment. Silent-type configurations are often selected for outdoor or noise-sensitive locations where enclosure and sound-control requirements need to be considered.

Q: Can multiple generators run in parallel?

A: Selected generator configurations can operate in parallel when equipped with compatible synchronization controls, switchgear and protection systems. Parallel operation can be used to increase available capacity, support load sharing or provide redundancy such as N+1 configurations, subject to the project design.

Q: What kind of environmental and weather protections are built into outdoor enclosures?

A: Silent and containerized enclosures feature weatherproof powder-coated steel or aluminum, stainless steel hardware, rain-proof louvers, and corrosion-resistant internal insulation rated for high ambient temperatures and dusty industrial environments.

Q: Do these generators comply with international quality and emission standards?

A: Yes. Our units utilize globally certified engines and alternators designed to meet international standards such as ISO8528 for generator performance, along with respective regional emission tier requirements.

Q: How is the generator protected during long-distance maritime transport?

A: Units are securely bolted onto heavy-duty wooden export skids, wrapped in moisture-barrier industrial shrink films, and protected with industrial desiccant packs inside sealed export-grade packaging to prevent corrosion during ocean freight.

Q: What documents and certifications are provided with the shipment?

A: Each unit comes with a complete factory test report (load bank test), engine and alternator certificate of origin, wiring diagrams, multilingual operation manuals, and customs clearance documents.

Q: Do you support third-party inspection (SGS, Intertek, BV) before shipment?

A: Yes. We welcome third-party inspections and regularly cooperate with agencies like SGS, Intertek, and BV for full-load testing, dimension checks, and documentation verification prior to dispatch.

Q: What spare parts support do you provide?

A: We supply extensive fast-moving maintenance parts (filters, belts, sensors) and can customize recommended spare parts packages (1,000 to 2,000 running hours) to ship directly with your main generator order.
