This project is a 600kW DC boost converter cabinet, delivered by Wenlida Power Electronics as a complete DC step-up solution. The unit is composed of three 200kW DC-DC power modules in parallel, with a rated power of 600kW. The input side is 780-1000Vdc (max 220A), and the output side is 1100-1500Vdc (max 182A), with a conversion efficiency of 97%. The device steps up the battery side / low-voltage DC bus to a 1500V DC bus, used in large-scale energy-storage stations, PV-station DC collection & step-up, and microgrid DC distribution. The cabinet features a touch screen (remote monitoring supported), dual-channel RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication, and all breakers are motor-operated. The touch screen integrates an electrical schematic, user login, parameter setting, parameter display, debug interface, real-time/historical fault query, data curves (power/voltage/current) and 4G information. Comprehensive protections are provided with auto-recovery after fault clearance.

图2：600kW DC升压柜应用场景 | Figure 2: 600kW DC boost cabinet application scenario

整套系统配置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；所有断路器均带电操功能。输入侧直流电源（电池簇/低压母线）经直流断路器接入3台并联DCDC模块的低压端口，升压后经高压侧直流断路器汇集至1500V直流母线输出至并网点/SST直流母线。所有电缆和信号线均采用底部下进线、下出线方式。

The system is equipped with a 10-inch local touch screen for on-site data monitoring and touch operation. One RS485 port is provided for remote telecontrol, telemetry and tele-adjustment, and all breakers are motor-operated. Input DC power (battery cluster / low-voltage bus) enters the low-voltage port of three paralleled DC-DC modules through DC breakers, is stepped up, and is then collected on the high-voltage side through HV breakers to the 1500V DC bus, feeding the grid-connection point / SST DC bus. All power and signal cables enter and exit from the bottom of the cabinet.

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.
