| 1 | Load and rated output | Compare the generator’s continuous and standby ratings, voltage, frequency, and phase with the intended loads. Ratings and available configurations vary by model and market. | List running and starting loads, and ask a qualified electrical professional to confirm sizing and required starting capacity. |
| 2 | Applicable standards | Check which standards and regulations apply in the destination market. ISO 8528 covers generating sets; it is a series of standards, so request the relevant part and supporting documentation. | Ask for the exact standard, edition, and test or conformity documents—not just a general claim of compliance. |
| 3 | Emissions and local rules | Emissions requirements depend on jurisdiction, engine category, power rating, intended use, and installation date. A generator’s eligibility cannot be determined from cylinder count alone. | Confirm the applicable emissions rules with the local regulator or an authorized compliance professional before ordering. |
| 4 | Documentation and traceability | Review the engine and alternator specifications, serial-number identification, wiring information, operator manual, and maintenance instructions. | Request documents for the exact proposed configuration and verify that model details are consistent across the quotation and technical records. |
| 5 | Warranty coverage | Warranty duration, hour limits, exclusions, and coverage differ by supplier and product. Check whether parts, labor, travel, and transport are included. | Get the full written warranty and confirm when coverage starts, how claims are handled, and what maintenance records are required. |
| 6 | Parts and service support | Assess the availability of qualified technicians, routine service parts, technical assistance, and repair procedures in the operating area. | Ask for local service contact details, typical parts-ordering arrangements, and a clear escalation route for equipment downtime. |
| 7 | Operating conditions and total cost | Account for duty cycle, ambient temperature, altitude, enclosure, noise limits, fuel use, maintenance, and installation requirements. Performance may change with site conditions. | Request a configuration-specific quotation and operating data, then compare purchase, installation, fuel, service, and lifecycle costs. |
