JK Inverter BMS Communication

One of the major advantages of the PB2A16S20P is its inverter-oriented communication capability.

The BMS can communicate important battery information to a compatible inverter, allowing the inverter and battery to work together based on battery status and configured parameters.

Depending on the inverter and communication protocol, information may include:

Battery Voltage

Battery Current

State of Charge (SOC)

Charging Status

Discharging Status

Battery Temperature

Cell Voltage Information

Protection Status

Battery Alarms

Important

Communication is not automatically guaranteed with every inverter brand/model. The inverter must support the appropriate JK communication protocol and connection/interface. Correct communication cable, protocol selection and BMS/inverter settings are also required.

2A Active Cell Balancing

The JK BMS provides 2A active balancing.

Active balancing helps maintain better voltage consistency between individual cells by transferring energy between cells rather than simply wasting excess energy as heat.

This is particularly beneficial in a high-capacity 314Ah battery, where maintaining cell consistency can contribute to better overall battery performance.

JK 4.3-Inch Touchscreen LCD

The battery is equipped with a JK 4.3-inch Touchscreen LCD Display.

The touchscreen provides a convenient interface for checking battery information directly from the battery without depending entirely on a mobile phone or external monitoring system.

Information Available on the Touchscreen

Depending on the BMS configuration, the display can show:

Total Battery Voltage

Battery Current

Battery Power

Battery SOC %

Individual Cell Voltages

Cell Voltage Difference

Active Balancing Status

Balance Current

Battery Temperature

MOS Temperature

Charging Status

Discharging Status

Cycle Information

Protection/Alarm Status

The touchscreen makes battery monitoring much easier for home, commercial and solar installations.
