Hello!
I have a 3 phase ESS system with a PV inverter on the AC-in and another one on the AC-out.
Grid and PV inverters are measured with ET340 sensors that are connected with separate USB RS 485 cables to the Cerbo and of course configured correctly. In the ESS menu the grid meter is also selected. The following video shoes the problem with the AC loads and Grid readings.

As you see the PV inverter production, the battery charging and the critical loads are almost totally stable.
The grid and AC loads are jumping up and down for no reason. I have to mention here that all the loads on this system are only connected on the AC out of the Victrons so are only measured as Critical loads.
There is nothing connected between the grid and the Victron AC-in besides the PV inverter. So the AC loads should always be zero!
The problem is more intense when there energy values are high.
Any ideas?
