Boat currently has 120 30amp service
needs 220v for new ac
1 option ( I’m told) is to pull 120v from a breaker on main panel
to the victron autotransformer and the 220v out to the ac unit
ac out 1 from Quattro to autotransformer wired to 120/120/220
split then 120 to A side of current panel 120 to B side and the 220 to a sub panel with breaker for the ac unit.
is one way better than the other.?
im concerned about option 1 because I can’t find anything like that described in any victron manual
