This project is a 240kW storage DC-DC + 125kW PCS all-in-one converter cabinet, delivered by Wenlida Power Electronics as a complete integrated storage DC conversion and grid-tie inverter solution. On the DC side, six 40kW storage DC-DC modules are paralleled (rated 240kW): battery side 400-600Vdc (≤100A per module), converted to a 700-800Vdc DC bus (≤57A per module) at 97% efficiency, supporting CV/CC. On the AC side, one 125kW PCS accepts 615-950Vdc (max 203A) and inverts to AC400V three-phase 3-wire/4-wire (max 200A, 50Hz), realizing bidirectional energy conversion between the battery and the AC grid/load. The unit features a touch screen, RS485 (Modbus RTU) / Ethernet (Modbus TCP) / CAN2.0 three-channel communication, smart forced air cooling, IP54 protection and comprehensive protections. It suits C&I storage, PV-storage integration, grid-tie/off-grid supply and demand-charge management.

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接口和一路CAN接口，支持遥控、遥测、遥调功能。储能电池簇（400-600Vdc）经6台并联DCDC模块变换至700-800Vdc直流母线，再由125kW PCS逆变至AC400V交流侧并网或带载；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, and one RS485 port plus one CAN port for remote telecontrol, telemetry and tele-adjustment. The battery cluster (400-600Vdc) is converted by six paralleled DC-DC modules to a 700-800Vdc DC bus, then inverted by the 125kW PCS to AC400V for grid connection or load supply. All power and signal cables enter and exit from the bottom of the cabinet.
