Hello All

Is it possible to stop my battery from disscharging to the grid, i much prefer to keep all my stored energy to run the house only.
Thank you
John

Maz hi.
By default, in eco mode, it should export to the grid only after the batteries have filled up, or more generally when the solar generation exceeds consumption of the house plus the rate at which the batteries can accept energy (which tends to drop as they fill up).

There's usually a small trickle in/out of the grid since the inverter has to react to changes in usage,but that's negligible.
