Ditto...
"Pull ground along with PV to inverter."
Bond your panels to a single EGC wire.. and run it with your positive and negative PV wires to the charger/inverter.
Bond all of your metal structures... panel frames, chargers, inverters etc.. to the SINGLE EGC ground at the main panel.
Lightning mitigation is a whole other system involving air terminals higher than your array attached to ground rods.
Many install surge protection devices (SPD) and ground rods at the array so that when a huge EMF from a close strike in the air induces a huge voltage in the metal panel frames the SPD clamps shut and shunts that voltage to ground through the momentarily attached ground rod. After the strike the rod is not connected and you probably need a new SPD.
