Product Features

※ Advanced battery management system – highly integrated battery management system can realize seamless monitoring.

※ Perfect self-inspection and operation status detection function, combined with HMI display screen, the system operation information is clear at a glance.

※Perfect and reliable system control and protection strategies to fully ensure the safety of the battery and escort the extension of the service life of the battery pack.

※ Modular design, configurable and expandable – multiple energy storage units can be flexibly combined to expand into a larger energy storage system and can support up to 160 batteries in series.

※ Rich communication interfaces – multi-channel RS485, can, Ethernet, dry contact input and output interfaces, supporting communication with most PCs and monitoring servers on the market.

※ Flexible communication interface protocol – the factory comes with the company’s communication protocol, and PCs of different manufacturers can also be adapted according to customer needs.

※ Capacity is great — the built-in high-capacity memory chip can store a large number of key operational data, and an SD card can be added to store the historical data of the cell

※ Automatic circulation control and automatic parallel / offline control can easily realize the parallel connection of battery packs.
