I did not see the status, it doesn’t show (AFAIK) in VRM and I wasn’t until now at the unit. But the animation showed flow to the battery whenever the sun power was higher than demand. It did recharged the battery with the remaining sun light to 85%.
Yes, I have cable, I crimped & tested it myself as I didn’t have any suitable on hand. The battery is the one you found documentation for. The battery now shows in Cerbo GX Remote Console in Device List:
As for communication, there are no dropped packets:
It would be nice to have some documentation for this page - is it like ping? No dropped packages = OK? What about the state “ERROR-ACTIVE” - is that normal?
EDIT: Based on other posts, looks like “ERROR-ACTIVE” is actually OK and means “ERROR-CHECKING-ACTIVE”.
I’ve double checked now, the “BMS controlled” option still doesn’t show…
