This project is a 1.2MW PV + 1.2MW storage DC-DC system, delivered by Wenlida Power Electronics as a complete PV-storage DC-bus conversion solution. The system consists of six 200kW PV MPPT DC-DC modules (PV side 200-700Vdc, bus side 750-900Vdc; ≤350A PV-side current each) and six 200kW storage bidirectional DC-DC modules (battery side 1000-1500Vdc, bus side 750-900Vdc; ≤200A battery-side current each), housed in 2 cabinets (each 800×800×2100mm). The DC bus port is rated 1200kW/1600A (750-900Vdc), with PV ports 1-6 and battery ports 1-6 each 200kW per channel. PV DC-DC efficiency is 98% (HV 750V/LV 600V) and storage DC-DC efficiency 98% (HV 1500V/LV 900V), supporting MPPT or CV/CC/CP modes, with static stability ±1% and dynamic ±3%. 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 large PV-storage integration, DC-bus collection for renewable plants, PV-storage-charging and high-voltage DC micro-grids.

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。6路光伏阵列经MPPT变换、6路电池经双向变换,共同汇入750-900V直流母线,实现光伏发电与储能充放电的直流侧灵活调度。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. Six PV strings are converted via MPPT and six battery ports via bidirectional conversion, all collected onto the 750-900V DC bus, realizing flexible DC-side dispatch between PV generation and storage charge/discharge. All power and signal cables enter and exit from the bottom.
