Shorepower US&EU for 48V system

Hi I’m working a boat and like to know what the best products suited for my needs are.
I’ve got a 48vdc 690ah battery bank which I’ll use with some kind of inverter(s) to reach an inverter capacity of about 10kW, 120V 60Hz.
The battery bank will be charged from shore power, with a charging capacity of at least 100A and should be suitable for use in US (125/250Vac 60Hz) and EU (250Vac 50Hz), preferably I’d just have one shore inlet. One way to achieve this would be by using a Victron Isolation Transformer after the inlet, but the 3600W power isn’t enough for my needs.
So my question is can you parallel connect the Victron Isolation Transformers?

What charger(s) would be best for my 48V battery bank? (I’ve thought about Quattro but using it only as a charger seems like a waste)

What Inverter(s) should I use to output 120Vac 60Hz from my 48V batteries?

Or is there a completely different solution to my boat?, Thankful for answers.

Yes, you can parallel the Isolation transformers, but do ensure that equal wire lengths are used for all.
Best to use either the Quatro or Multiplus 2 for inverter/ Charger combination - this eliminates the need for separate chargers. Quatro has 2 AC inputs, Multiplus has 1 AC input. you can get both for 120V 60Hz, or set them up as 120-0-120, which may be better for a 10kW size install.

So it should be done like this? and split phase after the Multipluses.

If the Isolating transformers are 3.6kVA, then you only need 3 to provide for the 10kVA. The outputs are all paralleled, and this ac bus then has both ACin 1 from the multi’s connected to it.
