Hi
I was hoping someone can help.
I have a Growatt SPH5000 inverter. The inverter has been working fine for over a year.
Previously, I had 5kw of Lead Acid batteries, all worked fine.
Recently, I upgraded the batteries to 15kw Lithium Ion with a Daly BMS controller.
The Daly BMS shows correct details on the phone app (i.e 48V etc) via Bluetooth & Wifi.
However, the inverter is displaying a fault of "BMS Com Fault".
This error message is seen regardless of using RS485 or CAN connection between the BMS & Inverter.
I have 2 identical Daly BMS's controllers, both have the same issue.
Both BMS are able to communicate with my PC via the CAN A/B wires.
I have checked the wires for both RS485 & CAN (RS485 B connected to 1&8. And A to 2 & 7). And for CAN - H to 4 (Blue) and L to 5 (Blue/White)
I have changed the protocol of the BMS ( i.e set to Growatt & RS485/CAN).
The voltage from the BMS to the Inverter is healthy, i.e at 52V.
The inverter Mode is set to "Lithium".
What could I be doing wrong?
