FAQ

Q: How do I choose the correct silent generator capacity?

A: Generator sizing should consider the total running load, motor starting current, power factor, and future expansion. A capacity margin of 10–20% is commonly recommended.

Q: Can the generator operate as both prime and standby power?

A: Yes. Models can be configured for prime power, standby power, or continuous-duty applications according to ISO 8528 operating conditions.

Q: Are spare parts available after purchase?

A: Yes. Routine maintenance parts such as filters, belts, sensors, AVR modules, controllers, and consumables are normally available for long-term supply.

Q: What maintenance intervals are recommended?

A: Engine oil and filters are generally serviced every 250–500 operating hours, depending on engine manufacturer recommendations and operating conditions.

Q: What warranty is typically provided?

A: The standard warranty is 12 months after commissioning or 1,000 operating hours, whichever comes first, excluding normal wear parts.

Q: What export documents can be provided?

A: Available documents include Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin (CO), Form E (where applicable), CE Declaration, Test Report, and User Manual.

Q: Is installation guidance provided?

A: Yes. Each generator is supplied with installation drawings, operation manuals, wiring diagrams, maintenance schedules, and remote technical support. On-site commissioning support can be arranged when required.
