How can the outlet strip show an open ground if there
is no ground?

Please draw the circuit.  That would make things much clearer.

Please draw the circuit.  Please include all the wires involved
in the outlet strip and the circuit tester.

That could be for lightning protection.  That's on the DC side.

It would be extreeeemely unsurprising to find that the DC side 
is transformer-isolated from the AC side of the inverter.

Please draw the circuit.  Maybe you are smart enough to discuss 
circuits without the aid of a diagram, but I am not.
