This project is a 250kW storage DC-DC power cabinet, delivered by Wenlida Power Electronics as a complete storage DC conversion solution. The system consists of seven 40kW storage bidirectional DC-DC modules (input 450-850Vdc, output 400 or 800Vdc; ≤90A input and ≤100A output per module) in parallel, with 97.5% efficiency (HV 800V/LV 400V) and CV/CC/CP modes, static stability ±1% and dynamic ±3%. The whole unit is rated 250kW: input port 450-850Vdc/556A, output port 400 or 800Vdc/625A. It features a touch screen (with remote monitoring), dual-channel RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication, forced air cooling and IP20 protection. It suits energy storage plants, battery pack charge/discharge, DC micro-grids and high-voltage DC-load supply.

整套系统提供10寸本地触摸屏，供客户监控数据和触摸操作；提供一路RS485接口支持遥控、遥测、遥调功能。7台DCDC模块在输入侧（450-850Vdc）与输出侧（400或800Vdc）之间双向变换，将储能能量稳定变换到目标直流电压等级。所有电缆和信号线均采用底部下进线、下出线。

The system provides a 10-inch local touch screen for on-site monitoring and touch operation, and one RS485 port for remote telecontrol, telemetry and tele-adjustment. Seven DC-DC modules perform bidirectional conversion between the input side (450-850Vdc) and the output side (400 or 800Vdc), converting storage energy to the target DC voltage level. All power and signal cables enter and exit from the bottom.

设备搬运说明 | Equipment Handling Instruction

机柜底座开有两个方形孔，搬运时叉车两根货叉通过方形孔叉入机柜底部，移动过程中需保证缓慢、平稳，避免设备磕碰倾倒。

Two square holes are reserved at the cabinet base. Insert two forklift forks through the square holes to the cabinet bottom during handling. Move slowly and steadily to prevent collision or tipping-over.
