You could put in the green ground screw to bond neutral/ground bar to box, move all ground wires to that bar, remove the extra ground bar.
Technically I think a wire between the bars should be sufficient to trip largest (or all?) breaker, but your will never see more than inverter can drive.
The deal is, we don't want to rely on current through steel box to protect branch circuits. Only good conductors. Bonding box protects for short to box.
Better to get things wired somehow so you keep your hands off. The moment you use two hands, it is more dangerous (ask me how I know!)
