"Passthrough" on a multiplus

Hello everyone,

my site is composed of these elements:

nr. 1 Multiplus 3000/48
nr. Smartsolar 250/85 & 3.2kW of solar panels
nr. 1 Cerbo + Display
nr. 1 Smartshunt
nr. VE.BUS BMS + nr. 4 Lithium 12,8V / 100Ah battery system from Victron
nr. 1 Energy Meter ET112

So here's the problem:

I activated the ESS Assistant but the panels are not working (I did not limit the power), meaning that there are about 180V but no Amperé flowing. Battery is about 97% (50V) and the inverter I see is in "passthrough" mode.
Home is now consuming about 100W.
The inverter has AC IN set as italian grid connected and all the parameters in VE.Config are fine.

Any idea how to fix this?

Thanks,

Mike

There are 6 main reasons described in FAQ in the ESS manual.

10.4. Q4: Why is the VE.Bus state in pass-through?
