1. Compatible design for 3 - 16 strings, charging and discharging through the same port, 3 to 16 strings, continuous charging and discharging at 200A (temperature rise within 30 minutes is less than 40 degrees).
2. Isolated RS485 / Isolated RS232 / Isolated UART (choose one of the three).
3. Isolated one - wire communication (independently optional), isolated CAN (independently optional).
4. Built - in Bluetooth / External LCD display can be connected and power supply is provided (independently optional).
5. Can be connected to 4 - lamp, 5 - lamp, 6 - lamp LED power display board (independently optional).
6. Battery pack low - temperature charging pre - heating function (independently optional).
7. Battery pack parallel constant - current charging module can be added (independently optional).
8. 4G remote data module (independently optional).
9. The industry's most advanced improved Kalman filter (predictive modeling) SOC algorithm, discharging with transient current under complex working conditions (the maximum error of lithium iron phosphate SOC is 3%, the same algorithm as BYD electric vehicles, not a simple amp - hour voltage method).
10. Can be suitable for the strong interference environment of the inverter.
11. The main program can be upgraded via Bluetooth, and parameters can be modified via Bluetooth.
12. Weak - current switch controls discharge, and the Bluetooth APP can turn on/off discharge (standard configuration).
13. The charging and discharging ports can be short - circuited arbitrarily.
