High battery voltage alarm on ccgx coming from mppt
Maybe its a High voltage warning for the panel High volts going over 150 volts, so whats the max OC voltage of the solar string, As I could see the string voltage going high when the batteries are full and the MPPT is turning off.
As you are NOT on the VRM its a bit hard to tell, but in one of you screen shots I see the Panel voltage was 111 volts and on a very cold day with a lot of sun Maybe the voltage is getting up there
and maybe there is a display fault and reading is 151.63 volts and not 51.63
to prove this or not drop one panel out of the strings for a while and see if the problem stops
