ZTE ZXESM R321 Communication Energy Storage System

Smart Hybrid Use, Smooth Expansion
The R321 smart lithium battery can be used together with existing lead-acid batteries or lithium batteries in the network without an external combiner, supporting online expansion and replacement of backup batteries. When site load or backup time requirements increase, there is no need to remove the entire set; simply add one or more groups of R321 smart lithium batteries to complete the expansion.

Smart Boost, Long-Distance Power Supply Reducing Line Loss
The R321 smart lithium battery uses a DC/DC circuit to control the external voltage and maintain a set value, achieving boost discharge and effectively reducing line loss in long-distance power supply scenarios.

Smart Parallel Connection, No Output Derating
The R321 smart lithium battery supports up to 32 groups in parallel, using a CAN bus for parallel management control. The DC/DC circuit maintains stable output voltage, ensuring no output power derating when connected in parallel.

Long Service Life, Short Charging Time
The cycle life of the R321 smart lithium battery is more than four times that of traditional lead-acid batteries. It is suitable for peak shaving and valley filling scenarios, supports high-power charging and discharging, and reduces charging time by over 70% compared to lead-acid batteries.
