The battery gets charged only by the PV array. Not the grid. The car charging interface is designed to take power from the PV's first. Since I don't drive the car every day it's not a problem but I could charge it from the grid if I needed to. With charge controllers you can dedicate how much power, where you want it to go, percentages, ect. At my "on grid" home here in the Burien area the utility acts as my battery. The system within less than a 1/60 of a second can go to batt power for inverting and maintain my household AC if the grid power hiccups or drops completely. Shall we say... a "big" UPS for the house. This is very, very common for folks who are "grid connected". You obviously just have to spend a little bit more money, but if you want absolutely bullet proof AC that can't fail.. it's the only way to go. Net... net though the PV array gives me a "surplus" of power to the grid over time and thus the FIT.
