In the examples above, the battery is charged to 100% even though the forecast is for uninterrupted sunshine (the forecast values are the max achievable In winter for me). If the battery was at a higher state of charge it would charge less. For example:
2023-11-25 00:20:58 38 % 7.7
Charge instruction set: 80% target at charge rate of 36%
(I have set a minimum of 80% to reduce the risk of undercharging)
It does look like when the battery is fully depleted at 4% the forecast is ignored and the battery charged to 100 regardless. Because this behaviour is inconsistent with normal operation, it makes it hard to correct for by adjusting usage amount.
