Power usage

[JCS68]

Looking for answers why my kWh usage on my AGL bill is about 50% higher than the usage from the grid shown on my solar edge app?

I have no controlled load. 

i would expect the readings to be very close,

Is this a new thing happening with an established solar system, with no past problems ?

Or, a new-ish SolarEdge system, and this is an issue with your first bill ?

My SolarEdge data and AGLs figures are close each quarterly bill, usually so close it's a matter of a kwh or so.
