Journey from 1P to 3P completed! Next step will be load rewiring in distribution box.

Meanwhile in attached picture one Item is missing. It is 3P 12kW ongrid solar system connected between Victron AC IN and Victron smartmeter. It is Sungrow and not visible by Cerbo GX. There is litle sun and those 200 W produced are lost in calculations.

I have two questions:

  1. How ESS will act when ongrid PV will generate 10kW? What aditional settings recomended?

  2. As this is not Fronius inverter, did anyone made Sungrow or any other PV inverter coupled on AC IN side visible?
