R27 LE - electrical

[Jcat2010]

A recent post has me wondering about two electrical issues.

Anyone have a good AC wiring schematic for the R27 with genset and inverter ? Specifically, are the ELCI and galvanic isolator only in the shore power circuit - between the main panel and the shore power receptacle ?

Also, how is neutral to ground switching achieved for the inverter and the generator ? Is it via the main interlocked breakers (I have three breakers, shore power, Genset, and Inverter breakers, mechanically interlocked) or within the Inverter and the generator (by relays ?)

The shore power is by way of the 30 amp receptacle, to the ELCI at the location of the ELCI the shore power grounds should be isolated (separated) from boat grounds, and the shore power ground is routed to the Galvanic isolator and then back to the ELCI to connect to the boat ground.

I have not torn into the inverter/charger but I ASSUME the neutral ground bond is at the inverter and is switched depending on the source. BUT I AM NOT 100-% sure of this yet.

A full schematic may exist but the only one I can find is in the owner's manual.
