Mine is also estimated for 11 September and I’m also wanting to know if it will be fixed/adjusted (my estimate is 13.7kWh while my inverter shows 46.6kWh)
The solar input is still estimated for 11 September. The inverter recorded 32.08 kWh. AGL online data shows the electricity bought from grid was 14.38 kWh and that sold to grid was 6.84 kWh; meaning a usage of nearly 40 kWh. Our average daily usage is about 16kWh.
The 11/9/19 is still showing as an estimate for me too and now 26/9/19 is giving a low estimate too (13.7kWh on AGL estimate vs 34.2kWh showing on inverter)
It has now been fixed for me too. But now the Solar Monitoring Web Page has not been updated since 25/9/19. If it is not one thing it is another that misfunctions!
