Is that right? It doesn't make a lot of sense to me but I don't have a ton of knowledge about such things.
You need a qualified electrician then as inverters are AC and need to be wired correctly.
Normally a boat with shore power
has grounding standards in place which should be conformed to by any new AC system installation
On shore power
wants to go home to the local power station and will use whatever means available to get there. With an inverter, home is back on the boat so there is maybe less chance for you to get a shock....generally speaking.
You should abide by the standards set in the country your boat was made in.
Get a marine
electrician, don't try to solve it by reading these forums
... even though there is lots of great advice
. Do a search on Shore power grounding maybe.
AC, shore power, inverters and generators are too dangerous to be played with when you do not know what you are doing.
