Energy Storage
QuiSure delivers engineered solutions for modern ESS, covering PCS conversion, high-voltage battery protection, DC/AC aggregation, and residential storage. Focused on safety, stability, grid compatibility, and reliability, our systems enable safe, efficient, and scalable energy storage.
Pain Points in the Application Scenario
Single-cluster short-circuit current of 11–13.5kA requires isolation switches with adequate short-time withstand capability. Condensation caused by battery temperature cycling demands high protection performance.
Value of the Solution
Industry-leading short-time withstand rating of up to 20kA/0.15s, eliminating equipment-damage risks from battery-cluster short circuits. Handle sealing rated up to IP67 prevents condensation-induced short-circuit failures, ensuring zero-risk protection. NDZ3AT-P series, combined with fuses, supports expected short-circuit currents up to 15kA industry leading—preventing high-current surge damage. NDZ3AT-H/LNEVH products offer 30kA short-time withstand capability, providing enhanced safety. VPD1000-40/3P(T1+T2) and VPD600-40/2P SPD surge protectors realizes professional DC surge protection for the battery cluster system, effectively avoiding device damage caused by lightning surges and DC side transients and reinforcing the system's safety barrier.
