This included PDF associated with an POWER INVERTER describes the requirement for grounding the CHASSIS as well as the DC RETURN cables to be compliant with the NEC.
Perhaps your POWER INVERTER MANUAL does not go into much detail as listed in this specific PDF...
Read POWER INVERTER Install procedure section...
Although specific to a particular model of Samlex inverter this owner's manual contains a
lot of information about inverter installation in general and is certainly
far more informative than the pathetic manual which came with my own Motomaster branded inverter from Canadian Tire. It too has a chassis ground lug but the manual makes zero reference to it so last year when I wired the inverter to power our trailer "whole house" I didn't bother with it. I never had any issues I know of but this spring I plan to ditch the whole house scheme and wire the inverter output to dedicated duplex receptacles in the camper and this time intend to wire the inverter chassis ground lug to the frame of the trailer with 8 AWG wire. Thanks for that link Roy! :D
