What does COC on screen mean?
Do you mean SOC?
SOC = State of charge, the amount of energy in your battery.
no it is COC - it loads and then it shows COC
Can you please make a screenshot?
Ah, I thought you meant a Cerbo GX Display. It would have been good to mention what device you have.
thks to you for reacting
