If you only use 2kWh per day and you want to keep the SOC in the mid-range (as usually recommended for battery longevity) you could adjust the start or stop time as GerryAZ mentioned so it only replaces as much energy as you ...

It's probably on the verge of losing the next bar. The first bar is roughly 15% and each subsequent bar is roughly 7.5%. The numbers aren't exact so having 11 bars at 78.xx% SOH is not impossible although I'd expect it to be at 10 bars fairly soon.
