The PCS requires adequate protection and switch- ing capability on the AC and DC side in order to switch the system - also in the load condition - and protect the entire electrical circuit from faults and overcurrent events. Our switching and protection devices will also pro- vide your PCS with communication connectivity to the BESS control system.
Maximum PCS Controlled Current setting: 200 A. The maximum operating currents in controlled busbars or conductors are limited by the settings of the Power Control System (PCS) and may be lower than the sum of the currents of the connected controlled power sources.
The PCS is a bi-directional inverter that enables the batteries to charge and discharge with precision control. The PCS requires adequate protection and switch- ing capability on the AC and DC side in order to switch the system - also in the load condition - and protect the entire electrical circuit from faults and overcurrent events.
