I have a 4kwh battery now and as it's getting more sunny here, I need to come up with a solution to control the battery power export to home.

I have an ESP monitoring the main meter, telling me if I consumer from or export to grid. Also I have two micro inverters with some solar power (960w, 460w)) attached that always feed in. During summer the is enough to power the base consumption (200-350W).

So I would be thankful for ideas recommendations to control the battery that it does not feed into the grid. I have EVCC setup, but apparently that is not made for home batteries.

Where is the battery connected in this system? DC side of one of the inverters, or separately connected to another inverter/charger on the mains side

second case, separate battery with integrated inverter and panels

can the inverter be controlled?

Yes, FoxESS Avocado 22 Pro, via App or custom modbus integration.

that's an AIO system, it should have integrated battery charge/discharge control modes in it anyway unless i'm missing something

I would need to connect my meter to that system in some way, which I currently cant with esp home. Also it's unclear to me if that is working via cloud or not.
