38S121.6V 50A Integrated High Voltage BMS Battery Management System for Energy Storage UPS
GCE Integrated BMS Overview:
Integrated BMSs are composed of BMS main control board, BMU sampling board, high voltage board, switching power supply, Hall sensor, DC contactor, micro switch, power terminal, structural box, wiring harness, etc.
For home ESS, 38S121.6V 50A BMS can work with an inverter to construct a perfect home Energy Storage System. BMS typically works with an inverter, charger, UPS, or 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.
GCE HV BMS Configuration:
One complete set of HV 38S121.6V 50A 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.

High Voltage BMS Application:
GCE high voltage BMS is an intelligent overall solution. We can connect battery modules with different types of strings in series to higher voltage systems, GCE BMS will assign addresses to each connected battery module, and if a cell is damaged, we can easily find and replace it. Multiple battery clusters can also be assigned addresses through DIP switches. We allow 8 battery clusters to be connected in parallel. Of course, you can also connect more battery clusters in parallel to meet your MWh energy storage needs. But our suggestion is that you can use every 8 battery clusters as a battery bank and have N battery banks in parallel. Our BMU can be divided into 8 series, 12-16 series, and 17-24 series of three specifications of PCB. In this way, you can meet the average distribution of your various total strings of batteries.
