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. 1.jpg

Also, the "To Grid" energy is not shown.

Can I configure it somehow so to show the correct values in VRM ?

Hello Bruce,

You can see below how I added the ET112 between the grid and the AC loads (sorry I don't have picture now).

BTW, the ET112 is measuring the power and the energy consumed by my AC loads correctly.
