JK PB2A16S20P Inverter BMS The battery uses the JK PB2A16S20P Inverter BMS, specifically designed for high-performance battery systems and inverter-integrated applications. BMS Specifications Model: JK PB2A16S20P Type: Inverter BMS Charge Current: Up to 200A Discharge Current: Up to 200A Peak Discharge: Up to 350A Active Balancing: 2A Series Support: Up to 16S Cell Monitoring: Yes Temperature Monitoring: Yes Inverter Communication: Supported with compatible systems 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. 24V 314Ah Battery Energy Capacity The battery provides approximately: 25.6V × 314Ah = 8,038Wh Therefore, the battery stores approximately 8.04kWh of nominal energy. Actual usable energy depends on: BMS settings Depth of discharge Inverter efficiency Load characteristics Battery temperature Operating conditions Backup Time Examples The following figures are approximate and based on the battery's 8.04kWh nominal energy. Load Approx.
