It refers to the maximum amount of electricity that the generator set can generate, generally refers to the amount of electricity that can be generated during overload operation. Overload execution is not allowed at any time, and only continuous execution is allowed within 12 hours and the cumulative amount cannot exceed 1 hour. Ex: The rated power is 400KW, which means that the generator set can run continuously for about 12 hours with a load of 400KW. The standby power is generally 1.1 times of the rated power. The continuous time of the generator set according to the standby power load cannot exceed one hour. , then the standby power is 440KW, which means that the unit can load up to 440KW, but under the condition of 440KW load, it cannot exceed 1 hour continuously.
