Ground Wire Size for Multiplus 12/3000 watt inverter/charger

I'm using two positive 2/0 gauge wires and two negative 2/0 gauge wires per connection to battery. What size ground wire do I need for the inverter ground? If I'm reading correctly, it says I use the same wire for the ground which would be two 2/0 gauge wires for ground. Is that correct?

To protect for a DC positive short to ground fault scenario, you should technically use a ground cable that is able to carry the DC fuse / circuit breaker current.

Generally this will mean a similar size cable to the DC power cables, or possibly a little thinner depending how far oversized the DC cabling is to keep voltage drop down.
