What Are the Differences Between Centralized and String-Type ESS in Parallel C&I Projects?
C&I energy storage parallel systems use either centralized or string-type architectures. Centralized systems rely on a single high-power PCS to control all battery cabinets, offering simple structure but low redundancy. String-type systems equip each cabinet with its own PCS, providing higher flexibility, easier expansion, and better fault isolation. The two differ in control, parallel behavior, and maintenance needs, and the optimal choice depends on project size, power requirements, and expansion plans.
