Stand-by state switching

[rsaemann]

I have a H3 inverter, which got a new feature since spring 2024: Enabeling a standby-state and setting a stand-by threashold.
This means: If the inverter detects very few energy consumption, it will switch off its inner inverter mechanics and has about 0W loss.
This is usefull in winter: My inverter has almost 150-200W power loss when switched on. So at night, he consumes more power doing nothing than he collected during the day. By using the standby-state threashhold, the inverter will put itself into idle mode when the battery is low, so I do not need buy power for it.
But in spring and summer the problem is on the other side. When the inverter detects too low power usage, he is switched off and I need to buy from the energy supplier, although my battery is almost full.

Now comes my idea for intelligent standby-state:
I would like to know if somebody has already found the addresses for this state (enabeling standby, and setting the threashold).
If battery is full, then disable the standby. Should power everything from the battery.
If battery is low, then enable standby. Go to idle state to save power comsumption, when sun is down and battery is empty.

For your interest: When in Standby/Idle state, the backup energy supply is feed directly from the net side.
