A 1000 kVA diesel generator enquiry should not stop at capacity. For export projects, the supplier needs the site voltage, frequency, phase, duty rating, control requirement, enclosure type, and shipment limits before a package can be matched to the project.

What buyers should know first
For a 480V project, confirm whether 480V is the final load voltage, a transformer secondary, or one of several required voltage options. Also confirm whether the project is 50Hz or 60Hz. The site has a separate reference on 50Hz vs 60Hz diesel generator selection, which is useful before comparing offers.
RFQ checklist for a 1000 kVA package
| RFQ item | Information to provide | Reason to verify |
|---|---|---|
| Electrical output | kW, kVA, voltage, phase, frequency | Prevents alternator and breaker mismatch |
| Duty rating | Standby, prime, or continuous use case | Controls engine rating and cooling assumptions |
| Control method | Manual, auto start, ATS, remote signal | Defines controller and terminal requirements |
| Site condition | Ambient temperature, altitude, ventilation | Supports derating and radiator checks |
| Shipment limits | Container loading, lifting points, site access | Affects base frame, enclosure, and logistics planning |
Product references to compare
For live product context, review the 800 kW 1000 kVA Cummins diesel generator product page and the 800 kW 1000 kVA MTU diesel generator product page. These pages show the type of capacity range buyers often compare, but the final selection should follow the project data sheet.
Common configuration mistakes
- Requesting 480V without stating whether the project also needs 230V, 240V, or a transformer.
- Comparing generator prices without checking whether ATS, batteries, muffler, breaker, and fuel tank are included.
- Leaving cable entry, breaker frame, and grounding details until after order confirmation.
- Assuming a listed capacity is suitable for all ambient temperatures and altitudes.
- Forgetting witness test, factory test report, and packing document requirements for export purchasing.
Documents to request
Ask for the technical data sheet, generator outline drawing, controller description, alternator data, packing dimensions, test report format, and accessory list. If the project has consultant approval, request the datasheet format before the supplier prepares the final offer.
Questions purchasers often ask
Can one 1000 kVA generator support all factory loads?
It depends on running demand, starting sequence, voltage dip limits, and reserve margin. Send the load schedule rather than only the target capacity.
Should 480V be written as the only voltage requirement?
Only if all connected loads and switchgear are confirmed for 480V. Export projects often need multi-voltage review before production.
Is ATS normally included?
It depends on the quotation scope. State whether ATS should be supplied with the generator or handled by the site switchgear contractor.
What acceptance documents should be requested?
Typical requests include factory test report, wiring diagram, packing list, operation manual, and product photos before shipment.
Can the supplier confirm derating?
Yes, if the RFQ includes altitude, ambient temperature, ventilation condition, and expected duty.
