JKBMS JK-PB1A16S15P V19 | 150A Inverter BMS for Home Solar ESS | 8S-16S 24V-48V LiFePO4 | 1A Active Balance + UART + CAN + RS485

Solar-Native Battery Management — JKBMS JK-PB1A16S15P V19 150A Inverter BMS for 8S–16S Home ESS

The JK-PB1A16S15P V19 is purpose-built for home solar energy storage systems. Unlike standard BMS boards adapted for ESS use, the Inverter BMS series is designed from the ground up for direct inverter integration — with UART, CAN, and RS485 communication ports, 1A active balancing, and built-in Bluetooth monitoring. If you're building or upgrading a 24V–48V home solar battery system, this is the BMS that speaks your inverter's language.

Compatible chemistry: LiFePO4

Key Specifications

Why the Inverter BMS Series Is Different

🔌 UART + CAN + RS485 — True Inverter Protocol Support

Standard BMS boards offer Bluetooth and optional CAN/RS485. The JK-PB Inverter BMS series includes UART — the communication protocol used by most residential solar inverters for direct BMS-to-inverter dialogue. This enables the inverter to read battery state of charge, cell voltages, and protection status in real time, enabling smarter charge/discharge control and longer battery life.

⚡ 1A Active Balancing — Built for Daily Solar Cycling

Home solar ESS systems charge and discharge every single day. The 1A active balancer keeps cells matched through thousands of daily cycles — transferring energy between cells rather than burning it off as heat, maintaining full usable capacity over the system's lifetime.

🏠 Home Solar ESS — 48V LiFePO4 Ready

The 8S–16S range covers the most common home ESS configurations: 24V (8S) and 48V (16S) LiFePO4 packs. The 48V 16S configuration is the standard for residential solar storage systems paired with hybrid inverters worldwide.

Who Is This BMS For?

• 🏠 Home solar energy storage systems (24V–48V LiFePO4 ESS)
• ☀️ Residential solar + hybrid inverter installations
• 🔦 Off-grid solar systems requiring direct inverter BMS communication
• 🔋 Backup power systems with solar charging integration
• 🏭 OEM & DIY ESS builders requiring UART inverter protocol support
