Good day, a Victron 3 phase system with 2 x 5.1 kWh BSL batteries is behaving very peculiar.
Until recently, it was fully functional but suddenly it started to behave such that when the battery is being charged it will stop to charge between 85% to 87% SOC. And no matter what we do it will not charge further either from PV or from the grid. It appears as if the BMS is stopping charging at this point and we cannot figure out why.
We have verified all settings as per Victron instructions for the BSL batteries and have upgraded to the latest firmware on the Cerbo, Quattro's and MPPTs and it had no effect.
We have reached out to the battery supplier as we believe it is probably the BMS or the battery that is faulty but I thought it prudent to check the forum here if anyone has come across something like this?
Below is a screenshot taken right now when there is full sunlight and more than enough PV available.
Kind regards
