CAN Verified closed-loop confidence: high
- Protocol
- Pylontech CAN (SMA Li-Ion external BMS)
- Inverter setting
- Battery type = Lithium-ion (Li-Ion) / LiIon_Ext-BMS
- Battery / DIP
- Master US5000 A/CAN → SMA ComSyncIn; DIP all 0, Link0 empty; 500 kbps
Cable
Pylontech ↔ SMA ComSyncIn (CUSTOM cable: CAN-H/L line up on pins 4/5, but Pylontech GND pin 6 must be moved to SMA ComSyncIn pin 2)
500 kbps CAN, custom (GND pin6→pin2)
A straight patch lead gives no comms because CAN-GND pins do not match.
Known errors
| Code | Cause | Fix |
|---|---|---|
| Battery not detected | Straight Ethernet used; CAN-GND not mapped | Build a custom cable moving Pylontech pin-6 GND to SI ComSyncIn pin-2 |
