Use the same kVA, duty, enclosure, alternator, controller, ATS and delivery basis in both quotations. Otherwise the prices are not comparable.
Cummins vs Perkins comparison checklist
| Decision item | What to confirm |
|---|---|
| Exact engine model | Model code, origin, standby and prime rating at the required frequency. |
| Service and parts plan | Who will maintain the set, which consumables are stocked and how warranty parts are handled. |
| Complete genset scope | Alternator, controller, breaker, radiator, battery, exhaust, canopy and ATS. |
| Operating profile | Emergency standby, daily prime use, expected hours and site ambient conditions. |
| Commercial scope | FOB China or CIF Lagos, packing, documents, lead time and exclusions. |
Match the engine option to the real application
A hospital backup set, hotel silent generator, factory motor load and long-running remote project do not have the same requirements. Send the load schedule and operating profile before choosing a brand. For motor loads, confirm starting current and voltage dip limits. For long runtime, confirm cooling, fuel system and maintenance intervals.
Brand familiarity can help service planning, but it should not replace verification of the actual model and complete genset configuration.
Ask for model-specific documents and factory proof
Before payment, request a technical data sheet, proforma invoice, production schedule and written accessory list. For the confirmed order, request finished-set photos, test evidence, packing details and shipment documents. Do not accept a generic brand brochure as proof of the final configuration.
