JK BMS P-Link Parallel Communication Board for Multi-BMS Systems

Overview: JK BMS P-Link Parallel Communication Board

The JK BMS P-Link Board is a parallel communication module that enables multiple JK BMS units to operate together in parallel battery configurations. When you connect multiple LiFePO4 battery packs in parallel (each with its own BMS), the P-Link board synchronizes communication between BMS units, providing unified pack monitoring, balanced load sharing, and a single communication interface to your inverter.

Key Features of JK BMS P-Link Board

• Function: parallel BMS communication coordinator
• Compatibility: JK Inverter BMS V19 series
• Connection: RJ45 ports for each BMS unit
• Synchronizes pack voltage, current, SOC across all BMS units
• Single inverter communication output for parallel banks
• Compact PCB for in-enclosure mounting
• Plug-and-play setup, minimal configuration required

When You Need a P-Link Communication Board

If you are building a battery bank with multiple parallel LiFePO4 packs (for example, two 48V 200Ah packs in parallel for 400Ah total capacity), each pack needs its own BMS. Without a P-Link board, your inverter only sees data from one BMS, while the others operate independently. The P-Link board solves this by aggregating data and providing a single coordinated communication output.

Common Use Cases for Multi-BMS Systems

• Parallel battery banks for expanded capacity
• Modular battery systems where capacity grows over time
• Commercial installations with multiple battery cabinets
• Off-grid systems with redundant battery banks

Benefits of Parallel BMS Communication

Unified Battery Monitoring

The P-Link board aggregates data from all connected BMS units, providing your inverter with complete visibility of the entire parallel battery bank. This ensures accurate state of charge (SOC) readings, voltage monitoring, and current flow measurements across all battery packs.

Balanced Load Sharing

With synchronized communication, all BMS units work together to ensure balanced charging and discharging across parallel packs. This prevents individual packs from being overworked and extends the overall lifespan of your battery system.

Simplified System Management

Instead of managing multiple independent BMS units, the P-Link board provides a single communication interface to your inverter. This simplifies system configuration, monitoring, and troubleshooting.
