5. Common FAQ

Q1: What is the practical difference between prime power and standby power of YC6K500-D30 generator set?

Prime power (300kW/375kVA) is 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 (330kW/412.5kVA) is short-term emergency peak power, specially 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, otherwise it will accelerate aging of engine core components and shorten the overall service life of the unit. In actual engineering application, professional operators usually control the operating load within 80% of prime power to ensure long-term stable and efficient heavy-load operation.
