For the months April until June, my Enphase PV system has a reading of:
Exported energy: 1925 kWh
Imported energy: 609 kWh
Now, I got my first 3-month-bill for the same period from my electicity company, an this has a slightly different reading:
Exported energy: 2208 kWh
Imported energy: 640 kWh
So, the bill reads about 15% more energy delivered to the grid, and about 5% more energy imported from the grid.
Is there anything I can do, tune in PVOutput to get this readings closer together? As I see, I can apply rules here in PVOutput, but “only” for Power adjustements, and not for Energy adjustments, right? Is this the one and only choice I have to adjust this? I assume, that the electricity meter from the power company is more accurate than the power CT’s (current transformer) from the Enphase installation…
