Hi Guys and Girls

Maybe I have missed this in the past. I have 2 3000C connected to an axpert invertor but I am using ICC latest software with a cable for the Pi to control the batteries and invertor.

I am noticing that my system is not charging the one battery to SOC of 100 as shown in the pic. 

Any obvious suggestions?

Regards

Did you let them balance each other out before connecting then to the inverter?

Yup I had balanced them out before running. However I now notice my master battery red alarm light is on statically. I have had to reset reboot and rebalance the batteries. Seems to be working now and both SOC have gone to 100%. Possibly a faulty cell or battery?
