5. Common FAQ

Q1: What is the practical difference between prime power and standby power of YC6K600-D30 generator set?

Prime power (360kW/450kVA) refers to the continuous usable rated power of the genset, supporting long-term cyclic full-load operation. It is mainly used for daily main power supply, long-term off-grid power generation and stable heavy-load industrial production operation. Standby power (400kW/500kVA) is short-term emergency peak power, exclusively designed for sudden grid power failure or instantaneous heavy-load surge scenarios. It only allows short-duration emergency operation and cannot run continuously at full load for a long time. Prolonged overloaded operation will accelerate aging of core engine components and shorten the unit’s overall service life. In actual engineering applications, professional operators usually control the operating load within 80% of prime power to ensure long-term stable and efficient operation.
