That is a lot sent to grid, no storage with that honking system? although you seem to be getting paid more for the export than you pay to get from it lol Nice export rate you got.
I didn't get batteries because we are lucky enough to have 1:1 net metering so the grid is like a giant battery with no roundtrip efficiency loss. I already had a standby generator when I got the solar panels or I might have got some storage for backup purposes though.
