A FAT is most useful when it checks the exact order scope, not a generic generator sample. The buyer should define what evidence is required before shipment approval or final payment release.
Why a factory acceptance test matters for Nigeria orders
Generator imports involve technical, commercial and logistics decisions before the machine reaches site. A practical FAT reduces confusion by checking whether the ordered configuration is the same as the equipment prepared for dispatch.
This is especially important when the buyer has specified engine brand, alternator, controller, canopy type, breaker scope, ATS preparation or export documents.
Factory acceptance test checklist
| Check item | What to confirm | Why it matters |
|---|---|---|
| Nameplate and rating | Model, prime/standby rating, voltage, frequency and serial information | Confirms the equipment matches the ordered specification. |
| Controller setup | Controller model, start-stop logic, alarms and display readings | Reduces surprises during site commissioning. |
| Mechanical inspection | Engine, alternator, canopy, base tank, breaker and cable points | Checks visible build quality and ordered accessories. |
| No-load running | Start sequence, oil pressure, voltage, frequency and abnormal vibration | Shows the set operates normally before loading. |
| Load test | Agreed load-bank level, voltage stability, frequency stability and alarms | Provides stronger evidence than a brief idle-running video. |
| Shutdown and protection | Emergency stop, fault alarms or agreed shutdown simulations | Verifies basic protective functions. |
Documents and media evidence to request
A useful FAT package can include photos, test video, control-panel close-ups, nameplate images, packing images and the document list that belongs to the order. Buyers should also ask which items are still to be completed after FAT, such as final packing or shipping marks.
For broader procurement control, compare this page with the pre-shipment inspection guide, the CIF Lagos shipping guide and the China to Nigeria import guide.
FAT is not the end of project verification
Factory acceptance does not replace site checks. Installation, cable sizing, earthing, fuel arrangement, exhaust routing, ATS integration and actual site load performance still need local engineering review.

What should a generator FAT include?
A useful FAT should confirm the model and rating, controller functions, no-load and load-running behaviour, alarms, accessories, documents and packing evidence agreed in the order scope.
Is a factory acceptance test the same as site commissioning?
No. FAT checks the generator package before shipment, while site commissioning confirms installation, cabling, earthing, fuel system, transfer logic and load performance at the actual project.
When should FAT requirements be written?
The FAT scope should be written before production or before final payment review so both buyer and supplier know what evidence must be provided.
