Why am I pulling from the grid?

I finally got my system running, still waiting on pte. As you can see I’m only using .5kW in my home so why can’t the PW send that? Why do I need the grid to send .2?

This has happened fairly often and I’ve been checking my daily usage with my electric company and it’s still around 2-5kWh per day even though I have a 15kW system that far exceeds my usage. Like, by more than double. I’m trying not to have an electric bill at all but I’m still going to have a small one at this rate.
