The only thing this problem is preventing me from doing is buttoning up the system ... so the covers are off for now. It "runs" it just doesn't run like I want it to (that is with the SMA not throwing errors in its logs) ...I know it doesn’t help right now but I’m hoping within the next week or so I should have my system ready for testing. I have a canbus (https://canable.io/) to usb so I can probably see if I get similar results or at the very least run a CAN dump.
We have had one light flicker event, but I didn't witness it so I can't confirm if it was true or not, from the SMA being odd (even though the batrium now controls the remote relay (SMA SI Bat OUT > Batrium Relay > Remote trip circuit I created)
The only thing I can think of is that the CANBUS on the SMA SI requires the 120ohm resistor and pins 4/5/2 ... my IXXAT Usb-to-can does reference this is possible in the documents I have read but I don't have another setup on the side to test if this is true. I previously went through other pins for my electric motorcycle BMS / Controller to do the programming so I have never used those pins on my IXXAT before.
That said, the SMA SI will not run without a proper connection and input from the Batrium's Rj45 ... so it is "working" and at the same time not "working" I haven't tried a new cable yet ... it seems odd that a cat8 cable wouldn't be "good enough or better" than a normal Cat5 cable for example.
So yeah, all that to say having your setup doing a can dump in a week is very helpful as you might run into the same problem I am with the pins or you might not. And theoretically I got your same setup it should "work" for me to see what is going on. But right now, I can't get anything but a connection ... no Rx or Tx data on the computer side of things.
