Hi all, I would like to use a multiplus 2 as a charger (without PV). I would like to charge the battery from the grid (AC-in). When the battery is full, it should supply all connected AC loads up to a SoC e.g. 20 percent. The battery should then be charged again via AC-in. Can I achieve this with ESS or do I need additional logic (e.g. Node-Red or similar)?
