Hello, I have several solar panels and three different Victron Blue Solar chargers, a MultiPlus 12/3000, a BMV712 and CC GX installed. For the last several weeks I noticed that the Li Battery gets less and less charged, the charge cycle turns off at 93.5% by now. The charge slows down once the battery voltage on the BMV reaches 14.2V, though for the parameters enabled it should stop charging at 14.4V after three minutes.
I am looking for recommendations to charge the battery up to 99.5%, as it had worked like this for the last two years.
The only change in the installation is the addition of the CC GX and I replaced the MasterVolt inverter with a Victron MultiPlus 12/3000 (however, the unit is turned off most of the times), only the solar chargers are always on.
The system has worked very well so far, and I paid little attention. I also upgraded the firmware changes, as they became public. Since this is a gradual charge degradation, I wonder if any of the firmware changes causes this behavior.
