A factory acceptance test is the last practical checkpoint before a diesel generator set leaves the supplier. Buyers should agree what will be checked, what records will be shared, and which items must be corrected before packing.
What buyers should know first
The test scope should match the quotation and the project duty. A standby set, a prime power package, and a synchronized multi-set project do not need the same witness checklist.
In practice
For export projects, the useful record is not only a video of the set running. Ask for load readings, voltage and frequency records, alarm tests, controller settings, nameplate photos, and the packing list linked to the final configuration.
| Item to confirm | Why it matters | What to send with the RFQ |
|---|---|---|
| Load test scope | Confirms basic running performance before shipment | Expected load steps, duration, voltage, frequency, and duty rating |
| Alarm and shutdown test | Shows the control system responds to fault conditions | Alarm list, controller model, and required shutdown signals |
| Document package | Reduces customs, installation, and handover delays | Manuals, drawings, test report, nameplate photo, and packing list |
Before requesting a quotation
Share the load list, voltage and frequency, installation location, duty rating, enclosure requirement, control interface, and any consultant drawings. Yangzhou Tesla Power Equipment Co., Ltd. can then check the diesel generator set scope against the project assumptions instead of quoting from a single kW or kVA number.
- Confirm whether the test is routine, witnessed by video, or witnessed by a third party.
- Check that the tested voltage, frequency, and phase match the purchase order.
- Request clear photos of the engine, alternator, controller, breaker, and nameplate.
- Ask how punch list items will be recorded and closed before packing.

Common questions
Is a factory acceptance test required for every diesel generator?
A routine test is common, but the witness level depends on project risk, buyer requirements, and contract terms.
Can the buyer request a video test?
Yes, but the video should show meters, controller readings, load bank changes, and the generator set identification.
What should be checked before approving shipment?
Compare the test report, drawings, nameplate, and packing list against the agreed quotation and purchase order.
Should spare parts be checked during the test stage?
Yes. Confirm the spare parts list and maintenance documents before the set is packed for export.
