The current ABYC guidelines are a bit out of date, and they will require GFCI breakers by next summer. I think you would provide more protection for your boat and nearby swimmers if you added a GFCI in the circuit to the battery charger and took the AC ground through to the charger, but NOT to the DC negative. That would also eliminate the need for the galvanic isolator.
