PV production is shown as critical load

In VRM the PV production is shown as critical load. I already read on the forum I should switch my PV production to phase 1. I have two PV inverters combineer power 6kW this will exeed the limit of one phase.

Is there a different solution? I don’t really want to invest in expensive 3 phase energy meters.

I have a 3 phase MP ii system measuring solar production with two ET112.
