I have connected all load and PV at AC out. My Growatt inverter is measured by the 3EM, so I configured it at the AC OUT.
What happens is that VRM subtracts the PV power from the AC Load. So the AC Load does not shows the real power.
When I connect the PV to the AC IN and the load to AC OUT and I configure the Shelly as connected to AC IN, the grid power is not shown correctly.
The Grid Metering in the ESS menu is set to Inverter/Charger. I don't have a grid meter

What am I doing wrong?
