Product details

Integrated BMS 75S 100A Master Slave BMS with CAN RS485 protocol for Solar Energy Storage Syestem

Integrated BMS (Battery Management System) is primarily composed of the BMS master control board, BMU(battery management unit), high-voltage board, switching power supply, Hall sensors, DC contactors, microswitches, fuses, and power terminals, all integrated into a device.

This offers advantages like space-saving design, flexible installation, and cost-effectiveness, making it suitable for small-capacity batteries like LFP. The main application is charge-discharge management of LFP battery systems.

Specification】30S-75S, 50A/100A.

All-in-one design】The integration of all the key components into a single unit results in a space-saving and compact overall design.

Flexible Installation】The integrated nature of the BMS makes it easier and more flexible to install, especially in applications with limited space.

Cost-Effective】The integrated approach helps to reduce the overall system cost compared to assembling individual components.

Compatible inverters】The integrated BMS supports CAN & RS485 protocols and it is compatible with the protocol of most well-known inverter brands in the market, such as DEYE, Growatt, Goodwe, Sofar, Sungrow, Kehua, ATESS, Megarevo, Sinexcel, Pylontech, Solis Sermatec and more.

What You Will Get】1 integrated BMS, 1200mm voltage and temperature sampling wire harness.

 

BMS Key Features: 

  • Each battery management unit (BMU) covers 15 battery strings, with a total of 5 battery management units for 75 battery strings.
  • There are 3 temperature collection probes for every 15 battery strings, totaling 15 probes.
  • Hall sensors are used for current collection, providing safe and reliable operation without heat generation.
  • SOC estimation error is less than or equal to 5%.
  • There is 1 CAN and 1 RS485 communication interface for inverter/PCS-BMS communication, as well as 1 Ethernet interface for connecting to the host computer software.
  • LED indicators show the working status (4-digit SOC, 1 operation indicator, 1 fault indicator).
  • 3 DIP switches are used to set the BMU address.
  • 3 dry contact outputs are provided.
