I use a Woods/Yellow Jacket brand inline GFI for my Syncro Westy.
They come in all different wire sizes.
Mine is the 10/3 15amp version.
Roughly $45 at a contractors supply.

with the neutral side.  It will trip if there's the slightest difference
(along the lines of 20mA), since this indicates current flowing through
something that it ought not flow through (like a human body).  Inverters
shouldn't effect this operation.
