Hi all, i recently added a new battery to to the system, so now there is 2, 1st was installed with rest of system august 2024, i have an issue with the battery on bottom of stack not charging/discharging correctly. If i switch the batterys around it always charges the top battery fine. Have tried to get help from growatt but they are not to good at replying. New battery has been installed for about a month. Supplier told me to charge both to same soc a few times and then connect batterys together, works fine for about half a day but then lower battery goes on standby, any help/advice would be much appreciated!!
