I have an MPPT 150|70 charging my batteries and connected to CCGX.
I have a backup solar units connected to an MPPT 100|30 connected to the batteries.
as long as the MPPT100|30 is not connected to the CCGX I can see the MPPT 150|70 on the CCGX and it work properly and I can connect the MPPT 100|30 to my laptop using Victron connect and see that it is working properly.
But once I connect the MPPT 100|30 TO THE CCGX it takes few seconds and I get error# 66 (incompatible device) on the MPPT 150|70
I can't clear this error message.
It looks as if both controllers continue to charge.
CCGX= V 2.72
MPPT 150|70= V 2.00
MPPT 100|30= V 1.56
To my best knowledge these are the latest releases of the products firmware
Is this message a real problem?
If "yes" what is the problem and how to fix?
If it is not a problem how do I disable and remove the error message?
