Cable
Sofar ↔ Pylontech (Sofar-specific RJ45↔RJ11: BAT RJ45 pin4=CAN-H, pin5=CAN-L → inverter RJ11 — not straight Ethernet)
RJ45↔RJ11, custom
Use the CAN port, not RS485.
Known errors
| Code | Cause | Fix |
|---|---|---|
| ID52 | BMS Disconnected — no inverter↔battery comms | Confirm the RJ45↔RJ11 cable/pinout and that the CAN (not RS485) port is used |
