If you will be traveling the world, you will have to deal with the hassle no matter what you buy, so it really doesn't matter (220v-50hz is more common so could actually be a benefit).
A good fairly straight forward method is to set the boat
up as follows:
- Large battery charger
that functions on 110 or 220.
- Large inverter
that matches your boat system.
powers the AC loads and the battery charger
keeps the batteries
up. Eliminates issues with frequency and voltage regardless of the power source. Since the batteries
are largely just a pass thru, they don't experience significant wear and tear but can allow the charger to be sized for continuous not peak loads. The inverter needs to be sized for peak loads (such as starting the air/con).
If we have-
a 'Universal' 90-250 VAC 45-65Hz input voltage battery charger.
or other battery charging
etc also only charging
our battery bank.
Then our Battery bank powering our Inverter (or a number in parallel) running all our AC loads.
The advantages are many.
All original AC wiring
As stated previously the Batt charger only needs to be sized for average load, not momentary peak.
The battery bank will even out any peak loads.
Shore and Generator
is often 'dirty' sometimes varying surprisingly markedly in voltage and frequency. Good Inverters have a good clean output, so better for sensitive devices and appliances
Good inverters also have a good 'surge' capacity for Aircond start ups etc. If you add soft starts this is even better.
Victron PowerAssist, makes this even better when shore or generator is on.
This is basically a big UPS, so if your shore power
suddenly goes out you boat power doesn't.
So saving on rewiring and appliances. Spend a bit for a Universal voltage charger. The money
you save on not rewiring and appliances invest on good a inverter/s.
Just a suggestion.
