Site with existing generation - negative power use - battery model work?

I am looking at the results of my first modeling run and have some questions about the results. (I looked back at the forum discussion and I still wasn't clear on this.)

The site has a few MW of existing generation, so there are periods in the site's baseline hourly load data where the existing site is putting power onto the grid.

Now the site wants to add PV and Batteries.  In the modeling results, it is clear that the battery is storing the new PV system's output, but is SAM also able to know that the site's negative production hours are times that it could charge the battery and is it able to include those saving in the results?

Thank you!
