Product Description



GCE HV LiFePO4 Battery 38S 121.6V 50A Integrated BMS for UPS Home ESS Micro grid ESS Large Scale ESS Solar Carport ESS


Overview of GCE HV BMS:


For home ESS, 75S240V 100A BMS can work with an inverter to construct a perfect home Energy Storage System. BMS typically works with an inverter, charger, UPS, and PCS. In some cases, there will be communication protocols required for the communication between master BMS and another device. The BMS and the inverter work together to realize the energy storage function of peak shaving and valley filling.


The 30s to 75s BMS adopts a master-slave integrated design and relay solution to meet the lithium battery demand of multiple strings of small capacity batteries. Greatly reduce the use cost of users; 60s-270s adopts master-slave three-level architecture, which can meet the series and parallel requirements of high-capacity single lithium batteries within 1000V.




* Multiple communication interfaces
RS485, CAN, Ethernet, dry contact input, and output interfaces can establish communication with most PCS and inverters in the market.

* With 3.5inch / 7inch HMI display
Perfect self-test and running status detection function, with HMI display screen, the system running information is clear at a glance.

* Intelligent Cell Balancing
Efficient passive balancing is used to maximize the usable capacity of battery packs.

* Health Monitoring
Monitors internal resistance of individual cells and the measured capacity of the battery pack.

* Field Programmable
Parameters such as voltage ranges, current limits, and many other settings are easily field changeable.

* Current & Voltage Protection
Protects the battery pack from over-charge and over-discharge thereby extending cycle life.

* Thermal Management
Over-temperature and under-temperature protection with fan controls for cooling or heating.



GCE HV BMS Configuration:


HV 38S 121.6V50A BMS includes:

Master BMS, Model#: RBMS07S-38S50A and its wire accessories, include 6p temperature sensoring wires and 16p voltage sensoring wires.

There are two different models for integrated BMS, one is a standalone model while the other one is parallel with its cost slightly higher than the standalone model.
