This project is a 1.2MW storage power system, delivered by Wenlida Power Electronics as a complete storage DC-DC conversion and grid-tie integration solution. The system consists of 5 cabinets: 2 DC-DC power cabinets, 2 PCS cabinets and 1 grid-tie cabinet. Each DC-DC cabinet is configured with 12 battery ports (100-500Vdc wide adjustable voltage, compatible with various storage batteries, 200A/60kW per port), converted to a rated 750Vdc DC bus (600kW per cabinet, 1.2MW total for two cabinets). Each PCS cabinet is rated 630kW (max 700kW, highest efficiency >99%), AC400V 3-phase 3-wire grid-tie. The grid-tie cabinet outputs rated AC400V/2000kW. The storage ports have wide adjustable voltage and are compatible with various batteries, with energy meters on each port for power metering/statistics. It features a 10-inch main touch screen plus 7/8-inch touch screens on each cabinet, dual-channel RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication, and stable grid connection via transformer. It suits large storage plants, PV-storage integration, grid peak-shaving and C&I energy storage applications.

系统包含5面柜体（2面DCDC柜、2面PCS柜、1面并网柜）。储能装置端口宽电压范围可调节，兼容各种储能电池；各端口配备电能检测表对电能数据进行计量统计；整套系统提供10寸主触摸屏供监控与操作，提供一路RS485接口支持遥控、遥测、遥调。各柜前面板设故障/状态/电源指示灯（红/绿/白）、7寸触摸屏、急停按钮与门锁，所有电缆和信号线均采用底部下进线、下出线。

The system consists of 5 cabinets (2 DC-DC, 2 PCS, 1 grid-tie). Storage ports have wide adjustable voltage and are compatible with various batteries; each port is equipped with an energy meter for power metering/statistics. The system provides a 10-inch main touch screen for monitoring and operation, and one RS485 port for remote telecontrol, telemetry and tele-adjustment. Each cabinet front panel has fault/status/power indicators (red/green/white), a 7-inch touch screen, an emergency-stop button and door locks. All power and signal cables enter and exit from the bottom.
