300A + 2A Active Balance — No Compromises

⚡ 300A Continuous — For the Most Demanding Home ESS Installations
High-power hybrid inverters, large-format battery banks, and homes with significant peak load requirements need a BMS rated for 300A. The JK-PB2A16S30P V19 provides maximum current headroom for high-power discharge events while the 2A active balancer keeps every cell matched through daily solar cycling.

🔌 UART + CAN + RS485 — Full Inverter Protocol Support
UART enables direct BMS-to-inverter communication using the protocols supported by most residential hybrid inverters. CAN and RS485 provide additional integration options for advanced EMS and monitoring systems. Real-time battery state reporting allows the inverter to optimize charge/discharge decisions — maximizing solar self-consumption and extending battery life.

⚡ 2A Active Balancing — Daily Cycling at Maximum Scale
At 300A, cell imbalance can develop faster under load. The 2A active balancer continuously equalizes cells during charge, discharge, and rest — keeping your large-format battery pack tight and healthy through thousands of daily solar cycles.
