In the meter settings, you can activate a switch to indicate that a storage tank is present. If you activate this, we pay attention to typical control behavior and adjust the control. You can also set an eco offset in your meter settings. We then try to feed this power into the grid during wallbox control. The default setting of 100 watts covers most situations. If you want less storage discharge, increase the eco offset to 200 W - 500 W. For the wallbox settings, you should select the Clever charging mode, as the storage system could be discharged to a greater extent in the other modes. You should also leave the proportion of solar power at 100%, as with a lower proportion the difference is first taken from the storage system before the power comes from the grid.
