Battery discharging overnight

ZenUser27H5nGD6

Hi,
My AB2000X battery was at 28% when the night started. In the morning it was 11%. There was no house injection. The Hyper 2000 is set to follow Smart CT. What is wrong?

Das Gerät verbaucht selbstverständlich auch im Standby selbst Strom aus dem Akku.

Thank you. I thought about this but last night the battery was at 11% and this morning at 10%. All in Standby. So it doesn’t seem that it was normal to discharge from 28% to 11%. Something else went wrong

The BMS does not reliably determine the State of Charge (SOC). The SoC is determined by measurement. Unfortunately, this is not very accurate. In particular, small charge/discharge currents are obviously not recorded (and are therefore not included in the SoC evaluation).

Have a look at this wiki

I think Gemini will help to translate.

Awesome. Thank you. I will follow the recommandations you give. Best.
