My house is single phase. I am using a 3 phase carlo gavazzi et 340 meter. I have connected the system like the meters manual connection to Victron inverters, except I don't have a PV inverter like the drawing. MCB to slot 1, slot 4 to inverter and bridged to slot 5. Slot 2 to non critical loads in my DB. Is this the correct wiring of this system? What settings should I use to make sure the Quattro only supplies excess PV to my non critical loads and not feed back to the South African grid? (The batteries is Pylontech so I cannot put all my loads on the inverter output only critical loads)
