New Lithium Battery 723.2V 300Ah (216.96kWh) high-voltage modular energy-storage cabinet
The battery system consists of two high-voltage battery strings, providing a nominal voltage of ±361.6 V and a nominal capacity of 300 Ah. It is suitable for dual-bus high-voltage DC UPS applications, offering long cycle life, high safety, and fast charge/discharge capability. The system can continuously support a 80 kVA UPS at full load for over 2.5 hours.
The complete high-voltage battery system (723.2 V / 300 Ah) adopts a dual-string architecture composed of two independent 361.6 V / 300 Ah battery assemblies. The corresponding bus voltages are:
Positive bus: +361.6 V
Negative bus: –361.6 V
