How to setup anything like "Reverse Power Assist"

For a ESS with grid meter, I have additional AC coupled inverter what occasionally exceeds the allowed grid feed in capacity. How is a setup, to switch the Multis to charging mode in case of exceeding the grid feed in? It is the intention to lower the grid feed occasionally by charging batteries with MP2 instead of using additional MPPTs. Inverter is not Fronius but Kaco what also offers Sunspec protocol for Modbus.

In case of nearby 100% SOC I have to shut down the AC inverter by other methods or cerbo relay output but this seems another problem.

Install it on your ac 2 out. Then program it with the generator assistant.

If the ac supports modbus though you could probably use node red on venus os large to control it. Will be a more elegant solution.
