22.94 kWh from solar production were stored in my ab2000s battery from solarflow 800. Only 18.12 kWh were used in the house. That suggests only 79% usage efficiency of solar power storage. Is this normal? What are other users' numbers? What are all these losses from?
Note that the AC charging component in the image was from me charging the battery to 100% on day 1 in mid June. So the above numbers are conservative, at the end of the month the battery was likely not at 100% so the discharge figure for solar should actually be a bit lower (since it includes a little bit from the initial AC charging).
