So over the last couple of nights, my BYD B-Box 10.24kwh has started losing charge overnight.
A view over the last 7 days clearly shows this.
Victron 48/5000/70-100, running with a CCGX and a SmartSolar MPPT. ESS is running in Optimised mode with BatteryLife, Min SOC at the moment is 70% (Last night it was 65%)
Also noticed that I put nearly 7kwh of solar into the battery today for only a 29% climb in battery SoC.
There's no DC consumers on the system.
Batteries are 3 weeks old now.
Is this normal behaviour or do I have a possibly faulty battery/bms?
