A Synchronized cabinet is an intelligent parallel control system. It can be set to island mode, multi-unit parallel operation mode, or parallel grid mode. Running in parallel mode will automatically activate: Frequency tracking, the synchronous breaker switch, active and reactive load sharing, different power rating Genset paralleling, engine and generator monitoring, and protection and fault diagnosis functions. The control system has two selectable working modes: emergency and normal use. Both working modes can use parallel mode; normal mode can be set to automatic or manual control.
