The VRM is not showing the energy flow direction

Hello,

currently I have a pretty simple installation in my house. I have a ET112 energy meter between the grid and the AC loads and a Cerbo GX device to read the energy meter.

Also I have a PV microinvertor with 400W panel connected directly to the AC loads - it is not compatible with Victron products.

I wanted to log and analyze my actual consumption before expanding my installation. I plan to add additional PV panels, Multiplus inverter and Li Ion batteries to build an ESS.

Unfortunately the VRM is not showing the energy sent to the grid from the microinvertor . When the AC loads are small, the ET112 meter is showing a negative current and negative power, but the VRM is showing just zero.
