I have two Quattro 48/10Kva. The L1 unit has always had a very loud buzzing when in inverter mode even with no loads connected. L2 unit has never had this buzzing. Any clues as to why only the L1 unit sounds like this?
These are my first Victron gear so I'm not sure if this is normal but given the L2 unit doesn't make the same sound I wanted to run it past the community here.
