Product Description

GCE 384V 250A master and slave high voltage BMS with 4U iron case overall solution for BESS and backup

GCE 384V 250A high voltage BMS introduction:

We normally make 15/16 strings of cells as a 48V or 51.2V battery pack. 384V consists of eight 15S 48V battery packs connected in series.

you need to install GCE 15S slave BMS(BMU) into each of your battery packs.For whole system, you need to install 8pcs of bmu for each pack.

And all these 8 bmu connecting to each cells collecting voltage, tempreture from cells.automatically balancing the voltage difference. Master BMS(RBMS) will get datas from each BMU by cascading connection.

GCE High voltage BMS features:


1 Advanced battery management system---The highly integrated battery management system can realize seamless monitoring.

Perfect self-checking and running status checking function, with HMI display screen,

system running information is clear at a glance.

3 Complete and reliable system control and protection strategies, comprehensively guarantee battery safety, and escort to extend the life of battery packs.

Modular design, configurable and expandable---multiple energy storage units can be

flexibly combined and expanded into a larger energy storage system.


Abundant communication interfaces---multiple RS485, CAN, Ethernet, dry contact input

and output interfaces, supporting communication with most PCS and monitoring servers on the market.


The communication interface protocol is flexible---the factory comes with the company's

communication protocol, and it can also be adapted to the PCS of different manufacturers according to customer needs.

7 The built-in large-capacity memory chip can store a large amount of key operating data, and an SD card can be added to realize battery historical data storage

Automatic circulation control and automatic parallel/offline control can easily realize the

parallel connection of battery packs.
