Perkins diesel generator enquiries often arrive with only a target power rating and destination country. That is not enough for an accurate quotation. The supplier still needs duty rating, site load profile, frequency, voltage, ambient conditions, enclosure preference, and control requirements.
What buyers should know first
For export projects, confirm whether the request is for standby power or prime power before comparing prices. A standby-rated set for emergency use is not the same purchase as a generator expected to carry daily site loads. If the project requires a Perkins engine, state that preference early and ask the supplier to identify any equivalent options only as alternatives, not as replacements for the requested basis.
In practice
| RFQ item | What to confirm | Why it matters |
|---|---|---|
| Rating | kW, kVA, power factor, standby or prime | Prevents undersizing and wrong duty selection |
| Electrical | 50Hz or 60Hz, phase, voltage, breaker | Controls alternator and panel selection |
| Package | Open, silent canopy, container, trailer | Affects noise, footprint, transport, and cooling |
| Control | Manual, auto start, ATS interface, remote signal | Matches site operation and transfer scheme |
| Documentation | Datasheet, wiring drawing, test record | Supports engineering review before payment |
What to confirm before quotation
- Load list with motor starting current and largest single load.
- Site altitude, ambient temperature, indoor or outdoor installation.
- Required voltage and frequency at the destination site.
- Noise limit if the set will be near offices, hospitals, hotels, or housing.
- Fuel tank arrangement, cable entry, exhaust route, and maintenance access.
- Requested documents for customs, installation, and commissioning review.
Common mistakes to avoid
- Comparing prices without confirming standby versus prime duty.
- Asking for a brand name but not confirming the exact engine model offered.
- Ignoring voltage and frequency until after the quotation is issued.
- Choosing a silent canopy without checking airflow and service clearance.
- Sending only one total kW figure when several motors start at different times.
Documents to request
Ask for a technical datasheet, engine and alternator model list, controller specification, outline drawing, single-line wiring drawing when ATS is involved, packing dimensions, weight, and factory test record. For regulated projects, the purchaser should state required document formats in the RFQ.

FAQ
Can a Perkins generator be quoted from kW alone?
A rough price may be possible, but a formal offer needs duty rating, voltage, frequency, load type, and package details.
Should the RFQ mention standby or prime power?
Yes. It is one of the first items to confirm because it affects engine loading, alternator selection, cooling, and pricing.
Is ATS always included?
No. ATS should be requested clearly, including mains voltage, current rating, pole count, enclosure, and installation arrangement.
What if the buyer does not know motor starting current?
Send the motor power, starting method, and operating sequence so the supplier can review the likely starting load.
Can one quotation cover several destinations?
Only if voltage, frequency, ambient conditions, and documentation needs are listed for each destination.
A useful Perkins generator RFQ is specific enough for an engineer to check the package, but it does not need to lock every accessory on day one. Start with the operating duty, electrical system, site limits, and documents needed for approval.
