I had the same, 2 base green v2s, the first showed fine in the parallel group page the 2nd showed alarms. I think that page in the software is buggy. I connected in direct to my 2nd battery and it shows up fine no errors on the single pack page. Also manual says you will get incorrect info if looking at parallel group display when only have one battery. Use single pack screen.This doesn't look healthy :D Either you have some weird settings that it can't read the values properly or ... There are different passcodes for being able to write to different locations. I've not had to do it now for a while so can't remember, but I think it was 8888 and 6666 or was there a third one as well. I know I needed a different one to change the capacity (defaulted to 280Ah, I installed MB31, which is 314Ah).
