Pylontech modules blocking charge / discharge

I have 4 x 3000 pylontech and 4 x 3000c batteries connected together with one of the C models as master. I have noticed on the Venus GX under the Pylontech section that sometimes it indicates that only 4 batteries are online and 4 modules blocking charge / discharge. This mostly happen at night but during the day it indicates 8 modules are online. Is there a problem with my configuration?

From that screen we do not know what your settings are. Only what the system is detecting and doing.

So the system is seeing the batteries.

What other settings are there? On the mppt and victron? The linked page has the set up for Pylontec and Victron.

Usually though in a new system it is best to keep them charged for the first few days to help with balancing and "settling in". I have not personally used the 3000c but on the rest of the pylons i have seen they are only happy to cycle after a few days some even a week depending on bank size.
