A site acceptance test should prove more than engine start. Before operation, the buyer should confirm load response, alarms, protection, ATS transfer, ventilation, fuel system, and the documents needed for handover.
Yangzhou Tesla Power Equipment Co., Ltd. supplies diesel generator sets for export and project use. For this topic, the quotation is only useful when the purchaser states the site conditions, duty rating, voltage, frequency, enclosure preference, and any ATS or control interface requirements.
What buyers should know first
Factory tests and site tests answer different questions. Factory checks confirm package assembly and basic operation. Site acceptance confirms that the installed generator works with the project load, ventilation path, cable run, fuel arrangement, and control interfaces.
| Test area | What to observe | Record to keep |
|---|---|---|
| Start and warm-up | Starting time, alarms, oil pressure, voltage build-up | Commissioning checklist |
| Load steps | Voltage and frequency response under planned steps | Load bank or site-load record |
| ATS transfer | Start command, transfer timing, return logic | ATS test sheet |
| Safety shutdowns | Emergency stop and selected alarm tests | Alarm and reset record |
What to confirm before quotation
- Whether testing uses load bank, site load, or both.
- Load percentage, step timing, and minimum run duration.
- ATS transfer, remote start, alarm, and emergency stop test scope.
- Ventilation, exhaust, fuel, earthing, and cable checks before load testing.
- Who signs the handover record and what documents are required.
Where mistakes usually happen
Do not leave acceptance wording vague. If the purchase order only says commissioning included, the buyer and supplier may disagree later about load bank, fuel, crane, site wiring, ATS tests, or repeated visits.
Documents to request
- Approved drawings
- Factory test report
- Site acceptance checklist
- Load test record
- Operation and maintenance manual

For equipment selection, compare this requirement with the diesel generator set for project handover and the wider diesel generator set product range. For planning context, also review load bank testing checks.
Common questions
Is factory testing enough before operation?
No. Factory testing does not prove the installed system. Site acceptance should check the generator with site interfaces and planned operating conditions.
Who provides the load bank?
It depends on the contract. The RFQ should state whether load bank testing is required and who provides equipment, cables, and fuel.
Should ATS be tested with the generator?
Yes, when ATS is part of the standby system. Start command, transfer, retransfer, and cool-down behavior should be verified.
What records matter after handover?
Keep test reports, alarm records, approved drawings, manuals, spare parts list, and maintenance schedule.
