You should have 4 inverter outlets, each paired with another regular shore power outer next to it and marked with a blue label "Inverter Outlet". Located next to Bluray player, under dinette, front tv, rear tv.
The inverter is not large enough for most kitchen chores such as coffee maker or toaster and therefore not available at the galley, although the switch is there. It is basically there for entertainment features, computer use which is pretty slick because everything else but air conditioner works on 12vdc from the battery.
One might be tempted to increase the inverter size but I wonder (doubt) if the inverter system wiring is large enough to handle it.
