5. Common FAQ

Q1: What is the practical difference between prime power and standby power of YC6T600L-D22 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) belongs to short-term emergency peak power, only applicable to sudden grid power failure or instantaneous heavy-load surge scenarios. It does not support long-term continuous full-load operation, and prolonged overload operation will accelerate aging of engine core components and shorten the overall service life of the unit. In actual engineering applications, professional operators usually control the operating load within 80% of prime power to ensure long-term stable and efficient operation.
