Got a friend who has an odd situation I have never ran across and thought I would run it by you all.
He has a boat dock completely made out of wood with a fiber glass canopy. No metal anywhere other than bolts and nail holding the thing together. It is supported by pile driven wood poles. There is no utility service conductors of any kind ran to the dock.
He has a 400 watt solar panel on the canopy using a charge controller to keep batteries charged up, and the batteries running a 2000 watt inverter.
The inverter only has plug receptacles for the AC output which is both CB and GFCI protection. The inverter supplie one boat lift, one overhead light, and a stereo. The inverter is 12 volt and made for a vehicle. It has a ground terminal.
The question he asked me is how to ground the inverter? I say it does not need a earth ground reference. What say you?
