That definitely helps. So in your case all shore power feeds through the Mass GI 3.5, presumably protected by a 16A circuit breaker in the lazarette? Is that the size breaker you have? I have a 32A breaker in the lazarette, which is too large for the 4mm2 wire Amel installed, and it would not safely protect that size isolation transformer. I plan to change that to a 16A breaker and use a similarly-sized isolation transformer like yours (I am using the Victron 3.6 unit). I just want to be sure that the breaker doesn't trip all the time if AC loads exceed the 16 amps permitted.

This is the answer from Mastervolt concerning the Installation of charger/inverter on Amel 54 "The AC is not connected to the DC terminals inside, the DC is floating to the housing. however, the AC input is not galphanic isolated from the shore, for this you need a isolation transformer, and create your own ships ground in your boat. the combi Ultra has an option to switch on a ground relay, this means the neutral in AC output will be connected to the ground in inverter mode automatically. in charger mode (this means there is a AC input like a shore connection, then this relay will be deactivated, because theoretical, the hot and neutral line can be swapped, and you don't want the hot line to be connected to the ground. our high frequency isolation transformer is 88000355 mass GI 3,5 http://www.mastervolt.com/products/mass-gi/mass-gi-35-kva-16a-lightweight/ hope this helps, best regards, Edwin van der Kroon" Any comment ?
