How to Choose Your 500kVA Generator
1) Confirm load: add up connected kW and apply a 1.2–1.3 starting-factor for motor loads; size to prime if running continuously, standby if for backup. 2) Voltage/frequency: match local grid (50Hz 400V in most of Africa/Middle East/Asia; 60Hz 416V in parts of SEA/Americas). 3) Enclosure: silent canopy for populated areas, container for harsh/remote sites. 4) ATS: required for automatic backup (hospital, data center, hotel). 5) Engine brand: choose by budget, emission rules and local service. 6) Certification: tell us the destination so we pre-fit SASO / SONCAP / ESMA / PVoC.
