Entry-Level Solar Storage, Purpose-Built for Inverters — JKBMS JK-PB1A16S10P V19 100A Inverter BMS for 8S–16S Home ESS
The JK-PB1A16S10P V19 is the entry point to the JKBMS Inverter BMS series — purpose-built for home solar energy storage systems. With UART, CAN, and RS485 communication ports, 1A active balancing, and built-in Bluetooth monitoring, it delivers direct inverter integration at 100A continuous current. For smaller home solar systems and budget-conscious ESS builds that still demand proper inverter communication, this is the right starting point.
Compatible chemistry: LiFePO4

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, up to 100A)
- ☀️ Residential solar + hybrid inverter installations with smaller battery banks
- 🔦 Off-grid solar systems requiring direct inverter BMS communication
- 🔋 Budget-conscious ESS builders wanting proper inverter protocol support
- 🏢 OEM & DIY ESS builders requiring entry-level Inverter BMS

Used this BMS to replace a faulty off brand one. It took this BMS 4 weeks to fix all of the badly out of balanced cells.. none of them were similar to each other. Cells were .4v out and all over the place.. I couldnt take the pack a part to parallel balanced them so I had to let this BMS take its time to correct them. It saved me lots of cash. Im ordering another one for the other battery right now. Excellent shipping time to the middle of Canada.. about a week.
Perfect communication and support. Delivery was super fast. It's not the first time I've used their product. Highly recommend.
Recibido en tiempo. todav��a no lo he usado. todo parece bien.
Ottimo prodotto.
item as spec, fast shipping
