Electrical Consumption and Production values

I am trying to understand the values being reported in the simulation report. I built a simplistic system with only loads a PV array to try and better understand the numbers. I have PV system that has an annual production that is ~94% of the total AC consumption as set in my scaled annual average kWh. 

The simulation report shows the correct expected PV kWh production but has "grid purchases" in the production category. The Production table sums up both of these. Then the consumption table reports the expected kWh consumption per my scaled annual average value set in the design, but the total equals the number from the Production table.

I don't understand why the grid purchases are so high or why they are being reported in the production table. Can you help me understand what I'm doing wrong?

I can't seem to paste a screenshot here but the values read:

Production Table:

Imported PV Production 253,503

Grid Purchases 125,834

Total 379,338

Consumption Table:

AC Primary Load 270,465

Total 379,338
