5. Common FAQ

Q1: What is the practical usage difference between prime power and standby power of YC6MK350-D30 generator set?

Prime power (200kW/250kVA) is the continuous usable rated power of the unit, supporting long-term cyclic full-load operation, which is suitable for daily main power supply, long-term off-grid power generation and stable heavy-load industrial operation. Standby power (220kW/275kVA) is short-term emergency peak power, only designed for sudden grid power failure or instantaneous heavy-load surge scenarios. It can only work for a short time and cannot run at full load for a long time, otherwise it will accelerate engine component aging and shorten the overall service life of the equipment. In actual engineering use, it is recommended to control the operating load within 80% of prime power to ensure long-term stable and efficient heavy-load operation of the unit.
