These are input_boolean helper entities.
Sets the battery to charge at 1.8kW from the grid. This is achieved by setting it to 'Self-Powered' mode, setting a high reserve level and having Grid charging enabled.

script.powerwall_mode_time_based_solar |
Prioritises exporting of solar energy vs feeding the house (i.e. battery discharges to support house consumption). Just like the 'Force Export' mode, so does the 'Export Solar Surplus' control toggle rely on the 'Utility Rate Plan' being setup with a higher 'sell price' than the 'buy price'. Otherwise the Powerwall will prioritise consuming the solar power generated rather than exporting it.

This selector helper entity can be used to query which custom mode the Powerwall is currently set to, but also, changing it triggers the automation.powerwall_custom_mode_selector_control automation, which calls the script corresponding to the selected mode.

Energy providers will often provide time-dependent tariffs, usually in the shape of two time periods where one is higher demand so more expensive and the other is lower demand so cheaper. In other cases, providers will bill dynamically throughout the day, in half-hour periods, depending on many factors that influence the cost and carbon impact of buying, selling and supplying energy on the network.
Therefore, manually set schedules are required for automations, which is my case. Your automations may require other inputs for taking decisions.
Schedule that defines time periods when provider tariff is peak or off peak (effectively expensive or cheaper - high rate or low rate). Used to control an automation that enables charging of the battery at the cheap rate period Octopus Tariff Battery Mode Control. This particular schedule helper means low rate == cheap == off peak.
