Adding new Pylontech US3000C to system

Hi guys

New here. I've added 1 new US3000C bank to my existing setup as below:

Victron EasySolar 3kva with built in BlueSolar Charger MPPT 150/70

12 PV panels x 250w

Pylontech 2 x US2000 and 1 x US3000


I've made the US3000C the master and got the batteries to balance. Their voltages are almost the same when I tested them. I'm getting an error code #38 input shutdown due to battery over voltage. As per Victron, I've disconnected the PV and batteries from the system. I then added the batteries and then the PV back. The error code still keeps coming back.

Do the batteries need to be left for a day or so to balance?

Also need to know if I need to increase the charge current from the PV?

Regards,

D

Managed to sort it out. Left the batteries to balance overnight, then disconnected the batteries and PV, rebooted the system to clear the error codes. Then connected the batts and PV. All working.
