Deye SUN-125K-PCSL01HP3 PCS module 125 kW three-phase high voltage for C&I storage
The Deye SUN-125K-PCSL01HP3 is the 125 kW PCS module (power conversion system) at the heart of Deye's BOS-B commercial and industrial energy storage systems. It converts energy bidirectionally between the high-voltage battery bus and the three-phase grid, managing charging, discharging, peak shaving, load shifting and integration with existing PV plants.
It works with batteries in the 630-1000 Vdc range with charge and discharge currents up to 200 A and reaches a maximum efficiency of 98.5%. The rack module format, with IP65 protection and intelligent air cooling, lets you build modular systems scalable from 125 kW up to 2.5 MW by combining several PCS, MPPT and STS modules in the same architecture.
