I have an existing Off-Grid-system:
MPPT 150/45 (updated) --> VE.direct
MPPT 150/70 (updated) --> VE.direct
BMV 700 --> USB
Multiplus 48/5000/70 (updated to V460)--> VE.Bus
I changed the batteries to a new BYD B-Box Pro 10.0
All necessary parameters I programmed before changing the batteries.
After starting the BYD-Box the CCGX starts but all devices appear except the B-Box Pro. Because of that the batteries shut down after a while caused by no data connection.
The cable is OK.
What is missing to get appearance of the BYD- Battery Box ?
