jkraushaar I don't find the portal Settings tab the friendliest and easiest at first sight. The options are: ECO; Timed Charge; Timed Discharge; Timed Export; Battery Options and Reset to defaults. Just click/tap on ECO (to get a vertical line just to the left of it) and ensure it is Enabled, then click/tap Submit.
The old Mode 1 is now referred to as "ECO". For many people this is the mode you want to run in. The mode provides energy to your house from the inverter via PV or battery. When PV exceeds house load, the battery charges. When house load exceeds PV, the battery discharges. When the PV exceeds house load and the battery is fully charged (or charging at the maximum rate), the inverter exports to the grid up to your limit. If the battery is depleted and there is no PV, you will import from the grid to supply the house load.
If you want to charge or discharge for any reason (usually you have a Time of Use tariff that you can make/save money with), you can set times when this should happen.
