Pull request overview
This PR fixes an interaction between the “export more solar” optimisation pass and EV charging: it prevents the optimiser from converting an idle export window into a freeze export window when that window overlaps a scheduled car charging slot (unless the configuration allows the car to charge from the battery).
Changes:
- Update
optimise_solar()to skip enabling freeze export (export limit99.0) on idle export windows that intersect a car charging slot whencar_charging_from_batteryis disabled. - Extend the optimise-solar test harness to configure car charging slots and the
car_charging_from_batteryflag. - Add targeted tests verifying overlap handling (blocked vs allowed when charging-from-battery is enabled).
