Sizing
How do I choose the right kVA rating for a diesel generator set?
List all running loads, motor starting loads and future reserve requirements first. Then confirm voltage, frequency, application, ambient temperature and duty rating before selecting the final kVA.
What is the difference between standby power and prime power?
Standby power is for emergency backup during utility failure. Prime power is for longer running duty where the generator may operate as the main power source. The correct rating affects engine selection, cooling, fuel planning and warranty review.
Sourcing
What information should I send before asking for a generator quotation?
Send required power, voltage, frequency, quantity, application, destination country, destination port, noise requirement, certificate request and preferred engine or alternator brand.
Can I compare Cummins, Perkins, Weichai and Yuchai generator sets on the same website?
Yes. GeneratorSet.cn organizes product records and sourcing guides around engine brand, power range, application and buyer checklist so overseas buyers can compare options before RFQ.
Installation
What should be checked before installing a diesel generator indoors?
Check foundation, ventilation, hot air discharge, exhaust route, fuel line, cable route, grounding, access clearance and maintenance space before the generator arrives.
Why does a generator room need ventilation calculation?
Poor airflow can cause high coolant temperature, power derating and shutdown. Ventilation planning should account for radiator airflow, air inlet area, louver resistance and hot air recirculation.
Maintenance
What spare parts should be prepared for exported generator sets?
Common spare parts include oil filters, fuel filters, air filters, belts, coolant, batteries, hoses, AVR, controller accessories and basic sensors. The final kit should match engine model and operating hours.
How often should a standby diesel generator be maintained?
A standby generator should be inspected regularly and serviced by running hours or calendar time. Typical checks include battery, coolant, oil level, fuel quality, alarms, ATS function and load test records.
Shipping
What documents are usually needed when importing generator sets from China?
Common documents include commercial invoice, packing list, bill of lading, certificate documents, factory test report and packing photos. Exact requirements depend on the destination country.
What should I check in generator packing photos before shipment?
Check model plate, accessory package, controller panel, lifting points, rain protection, wooden or steel base, container number, seal number and visible damage before balance payment.
