My inverter is connected to the ground bus bar/grounding conductor in both the AC Main panel as well as the AC sub-panel to which it is connected. There is a lug on the inverter casing specifically for "DC Ground." The manual shows this ground being connected to the battery enclosure - and also indicates that it must be bonded to the ground rod with wire that is as large as the largest DC wire.
This would involve running ~20+ feet of 4/0 cable in my system. Which I would do... but my enclosure is made of wood - and thus no reason/method of grounding. Is there any reason the DC side of the system cannot float? Everything is bonded to my primary grounding electrode on the AC side of course. The ground/neutral bond is here at the meter as well.
