I am running a Victron Quattro 8kva (24V) 230V inverter and use it exactly that way.
Generally when running on dock
power all of the power is converted to DC (using a Skylla-I charger
and auto-switching isolation transformer). This means that the boat is running 230V/50hz
In this configuration both 230V busses are on the inverter only output, I do need to add a load sheading solid state relay for the hot water
heater and air conditioners so that if dock
power goes away these don't pull the batteries down.
I can also take the output of the isolation transformer and run it directly to one of the inputs of the inverter charger
. This means in Europe
I see 50hz/230V with 16A of capability, on a US 208V dock I get 60hz/208V, on a US 240V dock I get 60hz/240V, and on a US 120V dock I get 60hz/240V.
If the generator kicks on the inverter will prefer the generator input and shift in all cases to 50hz/230V.
Away from the dock, the hot water heater, air conditioners, and washing
machine are on the secondary output of the inverter. These are not powered on unless the generator input is active.
The really nice piece of this is:
a) everything is automatic and internal to the inverter
b) the shore power input is never overloaded as the inverter will support the input load and keep it below the isolation transformer or shore power limit
c) the generator input is never overloaded
Really love the Victron gear
, their support has been exceptional.
