JKBMS module interface communicating photovoltaic inverters

JKLink is an interface adapter compatible with the JKBMS bms of the JK-BD6Axxxxxx and JK-BxAxxxxxxxxxx families. JKLink Smart Battery Monitor is a professional product that allows you to integrate the battery with the inverter and check the battery status. Once connected, it will automatically configure battery parameters in the inverter and can send important parameters to the cloud via MQTT protocol. Installation is relatively simple, but it is recommended to be performed by an authorized, knowledgeable person.

Compatibility with inverters:

The JKlink Smart Battery Monitor is compatible with most inverters (Victron/GoodWe/SMA/Voltronic/MPPSolar/Invt/EaSun/Growatt/Deye/etc) that have an RS485 or CAN interface for battery management. Gives you the option to choose between different inverter families from the web interface.

Features and capabilities:

Display battery parameter data
Battery Voltage (V), Battery Current (A), Battery State of Charge (SOC), Total Power (Wh)
External and battery temperature (degrees Celsius)
Fan speed (rpm)
Fan speed control based on external temperature sensors/BMS and load/unload current
RS485 and CAN port for battery management in the inverter
Programmable relay, high or low battery voltage
WiFi internet connection for cloud-based monitoring and control (MQTT)
Web interface for battery status and parameters
Inverter and BMS status, charging/discharging status, voltage, current, power, SOC, capacitance, average cell voltage, cell delta voltage, external/MOS/internal temperatures, fan speed, relay status.
MQTT broker for Home Assistant and cloud services
