Connected up my Seplos-based battery to HYD 6000-EP inverter for the first time just last night. Battery is charging and discharging successfully, but am having problems getting the CAN communication working on it.
I connected an ethernet cable into the CANBUS port on the BMS, then connected wires as follows, based upon the Seplos and Sofar manuals:
Seplos CAN-H (PIN 5 - white/blue) into Sofar COM port CAN-H (PIN 1)
Seplos CAN-L (PIN 4 - blue) into Sofar COM port CAN-L (PIN 2)
Seplos ground (PINS 3 and 6 - orange + white/orange) into Sofar COM port GND-S (PIN 7)
However, when I plug it in, the alarm light on the inverter comes on for a second or so, and there is a BMSCommFault event in the log history. I have tried selecting both the PYLON and DEFAULT battery types, but the system reverts to GENERAL after the fault event.
I also tried not having the ground PINs connected but no change.
Anybody able to suggest what I've done wrong? Thanks!
