: You must connect your PC to the Console port of the master battery using a specialized RS232 to RJ45 cable. Ensure your COM port is correctly identified in
Essential for diagnosing issues that trigger BMS alerts, such as excessive cell temperature (e.g., 48-50°C during charging).
: A standard USB-to-RJ45 (FTDI) cable often requires modification because Pylontech uses specific pins: Pin 3 (TX), Pin 6 (RX), and Pin 8 (GND) . Configuration :
Monitor the data the BMS sends to hybrid inverters via CAN-bus, such as charge limits (typically ~53.2 V for a 48 V stack). Module Listing:
