Residual Grid Consumption During Battery Charging with Victron Multiplus II

[Baldric]

I have a Victron Multiplus II 48/10000 together with a Color Control GX and a DIY 16 kWh LiFePO4 battery installed in a house using AC-Coupling. The system is configured to cover the needs of the house, store the extra energy in the battery, and once the battery reaches 100% send the extra energy to the grid.

The issue is that while the battery is charging, the system still draws a small amount of electricity from the grid, as shown in the attached image.

Is there a way to avoid this? Can the system be configured so that it always sends a small amount of energy to the grid and the grid consumption stays at 0, as long as I have enough production from the panels and the battery?

PV Inverter : 2931W
AC Loads: 344W
Grid: 112W –> This is really annoying

Exactly zero is not possible due to a dynamic system.

What can be done is to always export, never import from grid, if battery have enough capacity when PV is missing.

In Remote Console → Settings → System Setup → ESS → Grid Setpoint

Test with setpoint -50W to -150W

Thank you @Radunre . It works…
