This project is a 1.2MW high-voltage bidirectional energy-storage DC-DC converter cabinet, delivered by Wenlida Power Electronics as a complete high-power conversion solution between a high-voltage battery cluster and the DC bus. The unit consists of seven 200kW storage DC-DC modules in parallel (rated 1200kW): battery-side voltage range 1164.8-1497.6Vdc (HV battery cluster, max 471A for the whole unit), converted to a rated 800Vdc DC bus (max 1500A), at 98% efficiency. The device realizes high-power bidirectional energy conversion between the 1500V HV battery cluster and the 800V DC bus, supporting CV, CC and CP modes, and is paired with a containerized battery system. It features a touch screen (remote monitoring), dual-channel RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication, comprehensive protections with auto-recovery, forced air cooling and IP20 protection. It suits C&I storage, PV-storage integration and 1500V HV-cluster storage stations.

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。1500V高压电池簇经7台并联DCDC模块变换至800V直流母线，向母线侧负载或PCS供电；所有电缆和信号线均采用底部下进线、下出线方式。整机由DCDC柜（800×800×2300mm）与电池集装箱（约3000×2438×2890mm）配套组成。

The system is equipped with a 10-inch local touch screen for on-site data monitoring and touch operation, and one RS485 port for remote telecontrol, telemetry and tele-adjustment. The 1500V HV battery cluster is converted by seven paralleled DC-DC modules to the 800V DC bus, supplying bus-side loads or the PCS. All power and signal cables enter and exit from the bottom. The unit consists of a DCDC cabinet (800×800×2300mm) paired with a battery container (~3000×2438×2890mm).

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.
