BCU + BMU Guaranteed Safety and Performance
Each module has a capacity of 10.24kwh, with an output of 102.4V 100Ah. Its operating voltage range is 672-784V, and the charge-discharge current is 45A/0.3C.
These modules use a BCU to monitor the operating status of every single cell, which helps prevent issues like overcharging, over-discharging, overheating, and short circuits.
The BMU unit on the top connects to each BCU, forming an intelligent BMS. This setup ensures the entire system operates safely and with high efficiency.

Work with Inverter/MPPT Controller
On the back of each module are RS485, CAN, and other ports. You can connect it in parallel with other modules to reach 30kwh, 40kwh, 50kwh, 60kwh, or 70kwh. It has strong compatibility and works well with most mainstream inverters to form a solar system. If you are unsure about compatibility with your inverter or MPPT controller, please contact us for a solution.
