Prioritize Grid Export Over Battery Charging

Feature Request: Prioritize Grid Export Over Battery Charging

Is it possible to configure the inverter to prioritize exporting power to the grid and only charge the battery when solar production exceeds the grid export limit?

Use Case:
I’d like to control when the battery gets charged. Specifically, during morning hours when electricity prices are higher, I want all available solar power to be sent to the grid. Battery charging should only occur in the afternoon when prices are lower and solar production exceeds the grid export limit.

While the Eco charge/discharge settings are somewhat helpful, they don’t fully address this scenario. For example:
I still need to set the battery to discharge when exporting to the grid and when solar production exceeds the grid export limit, the surplus energy is not automatically stored in the battery.

You can simply set the battery charge current to 0, see #363, works very well. The charge current gives you full control when and how much to charge.

Using battery_charge_current to 0 disables charging correctly. However, I fail to return to delayed/smart charging when I set a battery_charge_current >0. It will immediately and strictly charge at that current until the target SOC is reached. How do I return to delayed charging or at least PV surplus charging so it doesn't consume grid energy to charge the battery when household consumption + battery_charge_current * battery_voltage < PV Total`?
