Ich habe es jetzt einmal getestet. Wenn ich den Haken bei "Soft export control set" entferne, fängt er an, die Batterie leer zu saugen und ins Netz einzuspeisen. Bei Haken gesetzt und 0 % passiert nichts.

This is what AI says:

In Deye Hybrid inverters, the "Soft Export Control" and "Hard Export Control" settings are used to manage how much solar energy is exported to the grid, especially in regions where grid export is restricted or needs to be limited.

Here's a breakdown of what each setting typically means:

🔹 Soft Export Control

• Function: Limits the export of power to the grid gradually.
• How it works: The inverter monitors the power flow using a CT (Current Transformer) clamp and adjusts the inverter output to minimize export, but some export may still occur briefly due to response time.
• Use case: Suitable where minor export is acceptable or where regulations are not extremely strict.

🔹 Hard Export Control

• Function: Enforces a strict zero-export policy.
• How it works: The inverter completely blocks any power from being exported to the grid. It may even curtail solar production if the load and battery cannot absorb the energy.
• Use case: Required in areas with strict no-export regulations or where the utility provider mandates zero feed-in.

⚙️ How to Choose?

• If your grid operator allows limited or occasional export, use Soft Export Control.
• If your grid operator requires strict zero export, use Hard Export Control.

Both settings rely on correct CT clamp installation to measure grid interaction accurately. Misconfigured CTs can lead to incorrect export behavior.
