Product overview

The JK BMS V19 is a 200A active-balance inverter BMS built for solar energy storage systems. It manages 8S–16S lithium packs at 25.6V, 48V and 51.2V, and communicates directly with your inverter through RS485, CAN, Bluetooth and RS232 ports — so the inverter follows the BMS’s real SOC, voltage and current limits instead of estimating them from pack voltage.

A 4.3″ touch screen gives you live cell voltages, pack current, SOC, temperature and alarm status on the battery itself, with no laptop and no phone required. The same data is available in the JIKONG Android / iOS app over built-in Bluetooth, and parameters can be adjusted from either interface.

Key features

• 8S–16S, 25.6V / 48V / 51.2V — one board covers 8S, 15S and 16S LiFePO₄ packs used in 24V and 48V solar storage banks.
• 200A continuous current — suits large home storage and server-rack packs without paralleling BMS units.
• 2A active equalization — energy is transferred between cells rather than burned off, keeping pack capacity stable over thousands of cycles.
• Inverter communication: RS485 + CAN — works with mainstream hybrid inverters using Pylontech CAN, Deye/Sunsynk, Growatt, Voltronic/Axpert, Luxpower, SRNE, MUST, Goodwe and Sofar protocols.
• Bluetooth + RS232 — monitor and set parameters from the JIKONG app, or integrate over serial.
• 4.3″ touch screen — real-time cell and pack data on a colour display, touch settings included.
• Heating function — low-temperature heating control for cold-weather charging.
• Full protection suite — over-charge, over-discharge, over-current, short circuit, over-temperature and cell voltage dropout protection.
• Self-powered from the battery pack — no external power supply, <5mA without communication, <15mA with RS485/CAN active.
• CE certified.

Packaging and delivery

• Selling unit: single item
• Each BMS is packed with its harness set, temperature sensors and communication cable in a foam-lined carton suitable for international transit.
• Bulk orders are quoted with DDP sea shipping to your door. As explained in the note above, DDP sea freight is quoted per destination country and confirmed in writing before payment.

Inverter compatibility

The V19 firmware includes the protocols used by mainstream home-storage inverters: Pylontech CAN, Deye/Sunsynk, Growatt, Voltronic/Axpert, Luxpower, SRNE, MUST, Goodwe and Sofar, and Victron systems through a Cerbo GX over CAN. The inverter must be set to the protocol that matches its battery communication setting.

If you are not sure which protocol your inverter expects, send us the inverter brand and model with your inquiry and we will confirm compatibility before you order.
