Hello!
I've got an off grid setup with 3 quattro 48/15000, 2 SMA Tripower 25000TL and 5 modules of BYD LVL 15.4. Installation and configuration went through no hitches, all unit firmware was updated. CCGX usually reports high battery voltage even at 54.9v. Any ideas as to how to resolve this?
Regards.
If it is a new install you may find one or two cells inside the battery have gone higher than the rest in the pack. What we normally do on a new install is charge to the full voltage and keep them there for about a week and let the battery 'settle down' with no cycling so it can sort itslef out. A bit more difficult in an off grid situation.
I have not used byd but have seen the error on a few other brands.
If your pack total is not over the charge voltage max then that is most likely the issue of a cell imbalance with a runaway voltage.
