Enable seamless power flow between PV, battery, and PCS with AmpereHour’s recombiner. An intelligent DC recombiner designed for 1500V DC-coupled BESS architecture, delivering system-level protection in utility-scale energy storage architectures.
The AH-Recombiner is a centralised DC aggregation and protection unit in DC-coupled BESS systems. It is designed to combine multiple high-current inputs. A BESS recombiner serves as the electrical backbone that connects solar combiners, battery systems, and power conversion systems, safely distributing power to the battery and PCS.
AmpereHour’s intelligent recombiner ensures protection, real-time monitoring, and controlled distribution into a single engineered unit. Commercially, this recombiner reduces system complexity and improves the safety and reliability of the battery system. Designed to withstand harsh environmental conditions.
